Haryana BSEH Secondary Home Science cheat sheet

Home Science is the applied science of home and family living; it draws on biology, chemistry, physics, economics, psychology and sociology and applies them to everyday family situations.

Its five classical areas are food and nutrition, textiles and clothing, home management (resource management), child development, and family/community living; housing, hygiene and consumer education are commonly added.

Scope runs from the individual (health, diet, clothing) to the family (budget, relationships) to the community (sanitation, nutrition education, consumer protection).

Interdisciplinary character: Home Science is not one science but an integration; a single problem such as malnutrition is studied through food science, economics and child care together.

Career paths after Secondary: dietetics and nutrition, food technology and quality control, textile and fashion design, interior design, preschool/child care, community development, extension education, and consumer journalism.

Higher-study routes include B.Sc. Home Science, B.Sc. Food Technology, B.A. Fashion Design, B.Ed. for teaching, and diploma courses in dietetics, preschool teaching and interior decoration.

Public-sector roles include Anganwadi worker/supervisor, nutrition educator, extension officer, school teacher, and hospital dietitian assistant; private roles include food-service, retail textiles and child-care centres.

Entrepreneurship options: tiffin service, bakery, tailoring and boutique, day-care centre, interior consultancy, and home-based food preservation units.

A Home Science student is expected to demonstrate practical skills (cooking, stitching, budgeting, child observation) alongside theory; practical marks are part of assessment.

Family functions: reproduction, socialisation of children, economic support, emotional security, care of the dependent (young, old, sick), and transmission of culture.

Family types by structure: nuclear (parents and children), joint (several generations/related couples), and extended; by residence: patrilocal, matrilocal, neolocal.

Stages of the family life cycle: beginning (couple), expanding (young children), launching (adolescents leaving), contracting (empty nest), and ageing; needs and resources shift at each stage.

Needs are classified as primary (food, clothing, shelter) and secondary (education, recreation, status); Maslow's order is physiological, safety, belonging, esteem, self-actualisation.

Resources are human (time, energy, knowledge, skills, attitudes) and non-human (money, goods, land, community facilities); they may be renewable or non-renewable.

Resource characteristics: limited, usable in alternative ways, and interchangeable; management means choosing the best use of scarce resources to reach goals.

Relationships within the family rest on communication, role sharing, empathy and conflict resolution; authoritarian, democratic and laissez-faire styles produce different outcomes in children.

Community resources include schools, health centres, Anganwadi, panchayat, libraries, cooperatives and self-help groups; families both use and contribute to them.

Small family norm and delayed marriage are linked in Indian health education to lower maternal and child mortality and better resource availability per child.

Five food groups: cereals and millets; pulses and legumes; milk and meat products; fruits and vegetables; fats and sugars. A balanced diet draws from all groups in proportion.

Macronutrients - carbohydrates (4 kcal/g), proteins (4 kcal/g), fats (9 kcal/g); micronutrients - vitamins and minerals supply no energy but are essential.

Protein: made of amino acids; animal proteins are complete, most cereal proteins are limiting in lysine; combining cereal and pulse (dal-rice, roti-dal) improves protein quality.

Deficiency diseases: protein-energy malnutrition (kwashiorkor - oedema, moon face; marasmus - severe wasting), vitamin A (night blindness, xerophthalmia), vitamin D (rickets, osteomalacia), iron (anaemia), iodine (goitre, cretinism), vitamin C (scurvy), thiamine (beriberi), niacin (pellagra).

Vitamin classification: fat-soluble A, D, E, K (stored in liver/fat, excess can be toxic); water-soluble B-complex and C (excess excreted, must be supplied daily).

Health is a state of complete physical, mental and social well-being, not merely absence of disease (WHO definition); it is influenced by food, hygiene, environment and lifestyle.

Energy needs rise with age until adulthood, are higher in pregnancy, lactation and heavy work; a sedentary adolescent needs fewer kilocalories than a manual labourer.

Food safety: wash hands and produce, keep cooked food covered, avoid reheating repeatedly, use clean water; diarrhoea and worm infestation are largely water- and food-borne.

Adulteration tests commonly taught: starch in milk (iodine gives blue colour), metanil yellow in turmeric, chalk in flour; buying certified (ISI, FSSAI, Agmark) products reduces risk.

Meal planning is planning meals in advance to meet nutritional needs within available money, time, skill and seasonal foods; it prevents waste and monotony.

Principles: adequacy (all nutrients), balance, variety in colour/texture/flavour, economy (seasonal and local foods), satiety, and consideration of family members' needs, likes and religious practices.

Indian meal pattern: cereal staple (roti/rice), pulse (dal), vegetable, milk or curd, and fat; fruits and protective foods fill micronutrient gaps.

Meal frequency: three main meals plus healthy snacks; adolescents and children need snacks, elderly need smaller frequent meals; breakfast should not be skipped.

Food exchange lists allow substitution within a group - e.g. one exchange of cereal can be exchanged with another cereal, not with a pulse - to keep nutrient value constant.

Dietary guidelines for Indians recommend using whole grains and millets, limiting sugar and salt, using iodised salt, and including green leafy vegetables and fruits daily.

Special diets: during pregnancy add extra protein, iron, calcium and folate; during lactation add energy and fluids; in diabetes reduce refined sugar, in hypertension reduce salt, in obesity reduce energy-dense fried foods.

Cost control: buy seasonal vegetables and local fruits, use whole pulses and cereals, avoid packaged snacks, plan a weekly menu and a shopping list, and use leftovers safely.

Hygiene in meal planning includes clean utensils, safe water, covered storage and serving food promptly to prevent contamination.

Cooking methods: moist heat (boiling, steaming, stewing, pressure cooking) and dry heat (baking, roasting, grilling, frying); each changes nutrient retention and texture differently.

Water-soluble vitamins (B and C) are lost by leaching into cooking water and by heat; use minimal water, short cooking time, and steam or pressure cook to retain them.

Do not add soda (sodium bicarbonate) to vegetables or pulses for colour or quick cooking - it destroys thiamine and vitamin C.

Vitamin C-rich foods are best cut just before cooking, cooked in acid medium (tamarind, lemon) and not overcooked; copper vessels are avoided for acidic foods.

Effects of heat on protein: coagulation (egg white sets), denaturation; on starch: gelatinisation (rice absorbs water and softens), dextrinisation (bread toasts); on fat: smoking point and rancidity.

Preservation principles: remove moisture (drying, dehydration), lower pH (pickling in acid), add preservatives (salt, sugar, oil), apply heat and seal (canning, bottling), and use cold storage.

Home preservation methods: sun drying, salting, pickling (oil, salt, vinegar, spices), making jams, jellies, marmalade, squash and syrup, and freezing.

Jam sets with pectin, acid and sugar at the right concentration; jelly is clear fruit-juice gel; marmalade contains citrus peel; a good set is tested by the sheet or wrinkle test.

Rancidity is the spoilage of fats giving an off smell; prevented by storing oils in a cool dark place, in opaque containers, and by adding antioxidants naturally present in vitamin E-rich foods.

Food spoilage causes: enzymes, microorganisms (bacteria, yeast, mould), insects, moisture and oxygen; safe storage means cool, dry, covered and pest-free conditions.

Fibres are classified as natural (cotton, silk, wool, jute - plant and animal origin) and man-made (rayon, polyester, nylon, acrylic); staple fibres are short, filament fibres long and continuous.

Cotton: good absorbency, strength when wet, poor elasticity, shrinks; burns with a paper smell and grey ash. Silk: protein fibre, lustrous, weaker when wet; burns with a burnt-hair smell. Wool: protein, warm, felts on washing, burns with burnt-hair smell.

Polyester and nylon are synthetic, strong, quick-drying, thermoplastic (melt on hot iron), non-absorbent, and burn with a melting bead and chemical smell.

Yarn is made by spinning fibres; fabric by weaving (warp and weft interlacing), knitting (interlocking loops, stretchy) or non-woven bonding; weave types include plain, twill and satin.

Basic hand stitches: running, back, hemming, blanket, chain and buttonhole; basic machine seams: plain, French, run-and-fell; seam finish prevents fraying.

Body measurements for a garment: bust/chest, waist, hip, shoulder width, sleeve length, back length and skirt length; take measurements over fitted clothing, keeping the tape snug but not tight.

Pattern layout and cutting: place the pattern on the straight grain (parallel to the selvedge), use required seam allowance, mark darts and notches, and cut with sharp shears.

Care labelling and laundry: sort by colour and fabric, use correct water temperature, treat stains before washing, dry in shade for coloured fabrics, and iron at the fibre's safe temperature.

Stain removal: protein stains (blood, egg) with cold water - never hot; grease with absorbent powder or detergent; ink with alcohol; always test on a hidden part first.

Clothing selection considers climate, occupation, age, figure, fashion, durability, comfort and budget; clothing also protects from heat, cold, insects and injury.

Functions of a house: shelter and protection, privacy, space for family activities, storage, and a setting for health and social life.

Selection of a house/site: soil and drainage, safe water, sunlight and ventilation, access to school, market, health centre and transport, freedom from noise, dust and flooding.

Principles of house planning: orientation (long axis east-west to reduce heat), cross-ventilation with openings on opposite walls, zoning of activity areas, and provision for future needs.

Activity zones: living/social, sleeping/private, work/service (kitchen, washing), and circulation (passages); noisy and quiet areas should not overlap.

Kitchen work triangle links sink, cooking range and refrigerator; a short, unobstructed triangle reduces steps and fatigue. Work centres are storage, preparation, cooking, serving and washing.

Elements of design: line, form, colour, texture and space; principles: balance, rhythm, proportion, emphasis and harmony. Colour schemes are monochromatic, analogous and complementary.

Colour psychology: warm colours (red, orange, yellow) advance and make rooms look smaller; cool colours (blue, green) recede; light colours reflect light and make small rooms look larger.

Furnishing: curtains (length, fabric, lining), floor coverings, cushions and wall décor should match function and scale; washable, light-fast fabrics suit Indian conditions.

Space management: use vertical storage, multipurpose furniture, foldable items, wall niches and under-bed boxes; de-clutter regularly and store by frequency of use.

Ventilation and lighting: daylight plus cross-ventilation reduce dependence on fans and lights; task lighting is needed for reading, cooking and stitching.

Management process: planning (setting goals), organising, implementing and evaluating; it is cyclical and flexible.

Budget: a written plan of income and expenditure; steps are estimating income, listing fixed and flexible expenses, allocating for savings, and comparing actual with planned spending.

Fixed expenses recur regularly (rent, school fees, insurance); flexible expenses can be adjusted (food, clothing, recreation); savings should be treated as a planned expense.

Time management tools: daily time plan, priority lists, doing peak-energy work at peak-energy hours, combining tasks, and delegating within the family.

Energy management: work simplification (use labour-saving tools, arrange work centres, sit for long tasks), avoiding fatigue and maintaining good posture.

Decision-making steps: identify the problem, list alternatives and their consequences, choose, act, and evaluate the result - used for purchases as well as household plans.

Consumer rights include safety, information, choice, being heard, redressal and consumer education; the Consumer Protection Act, 2019 provides a three-tier redressal system (district, state, national commissions).

Standard marks to look for: ISI (BIS) for industrial goods, FSSAI for food, Agmark for agricultural produce, Hallmark for gold, and Ecomark for environment-friendly products.

Consumer responsibilities: check weights, dates and labels, ask for a cash memo, avoid impulse buying, compare unit prices, and complain with proof if cheated.

Advertising techniques (glamour, repetition, celebrity endorsement, bandwagon) aim to create desire; a wise consumer separates need from persuasion and reads the fine print.

Development follows principles: it is continuous, proceeds from head to foot (cephalocaudal) and from centre to periphery (proximodistal), and moves from general to specific responses.

Stages: infancy (0–2 years), early childhood (2–6), later childhood (6–12), adolescence (12–19); each has characteristic physical, motor, cognitive, language, emotional and social milestones.

Motor milestones: head control around 3 months, sitting with support 5–6 months, sitting alone 7–8 months, standing with support 9–10 months, walking 12–15 months.

Piaget's stages: sensorimotor (0–2, learning through senses and action), preoperational (2–7, symbolic play, egocentric thought), concrete operational (7–11, logical about concrete things), formal operational (11+, abstract reasoning).

Play is the child's work: it develops muscles, language, imagination and social skills; types include solitary, parallel, associative and cooperative play.

Immunisation schedule (Indian national schedule): BCG, OPV and hepatitis B at birth; pentavalent/OPV at 6, 10 and 14 weeks; measles-rubella and vitamin A at 9 months; boosters at 16–24 months and DPT at 5–6 years.

Breastfeeding: colostrum (first yellowish milk) is rich in antibodies and must not be discarded; exclusive breastfeeding for the first 6 months, complementary feeding from 6 months with continued breastfeeding up to 2 years.

Care of the newborn and young child: warmth, clean cord care, hygiene of feeding bottles, safe sleep, timely weaning foods, and watch for danger signs (poor feeding, fast breathing, fever, convulsions) requiring a health worker.

Adolescence brings puberty, growth spurt, secondary sexual characters, and needs for iron and calcium, menstrual hygiene, emotional support and correct information.

Personal hygiene: daily bath, oral care twice a day, handwashing with soap before eating and after toilet, clean nails, hair and clothing, and safe disposal of body waste.

Handwashing steps: wet hands, apply soap, rub palms, backs, between fingers, thumbs and nails for at least 20 seconds, rinse with clean running water, dry with a clean cloth or air.

Safe drinking water: boiling for 10–20 minutes or for 1–2 minutes after the rolling boil, chlorination (bleach solution in correct dose), filtration and covered storage; do not dip hands or dirty cups into stored water.

Sanitation: use of toilets, safe excreta disposal, drainage of waste water, covered garbage bins, and control of flies, mosquitoes and rodents to prevent diarrhoea, typhoid, cholera, malaria and dengue.

Waste segregation at source: biodegradable (kitchen waste, paper) for composting and non-biodegradable (plastics, glass, metals) for recycling; hazardous waste (batteries, medicines) kept separate.

Composting converts kitchen and garden waste into manure; vermicomposting uses earthworms; both reduce landfill load and enrich soil.

3Rs - reduce, reuse, recycle - plus refuse and rot; single-use plastic avoidance, cloth bags, and repair of items reduce environmental burden.

Pollution types: air (smoke, vehicle exhaust, burning waste), water (sewage, industrial effluent), soil (plastic, chemicals), noise (loudspeakers, traffic); each has specific health effects.

Water conservation: close taps, fix leaks, reuse rinse water for plants, rainwater harvesting; energy conservation: switch off unused lights, use LED and solar water heaters.

Environmental awareness extends to tree planting, protecting local water bodies, avoiding open burning, and participating in community cleanliness drives.

A project report typically includes title, introduction/need, objectives, method or procedure, observations or results, discussion, conclusion and references.

Practical skills assessed include cooking and plating, stitching a simple garment or article, stain removal, first aid, child observation, budgeting, and making a consumer complaint.

For a food practical, record the recipe with ingredients in standard measures, method, time, cost per serving and nutrient contribution; use standard cups and spoons, level measures.

For a textile practical, record body measurements, fabric chosen and why, pattern, stitches used, and finishing details; keep seam allowances even and press as you sew.

A child-study observation records age, setting, behaviour observed (motor, language, social), and interpretation against developmental norms - without naming the child.

A consumer-education project can compare unit prices of two brands, check labels for FSSAI/ISI marks, or draft a complaint letter with a cash memo as proof.

Market surveys should use a simple, short questionnaire, a clear sample (e.g. 20 households), and tally results; avoid leading questions.

First aid basics: for burns cool with running water, for cuts press clean cloth to stop bleeding, for choking and fainting follow taught steps, and always refer serious cases to a health facility.

Safety in the practical room: tie hair back, use dry hands for electrical appliances, turn pot handles inward, keep a wet cloth away from hot oil, and know where the first-aid box is kept.

Evaluation of a practical uses criteria such as accuracy, neatness, hygiene, time management, use of resources, originality and presentation.

Extension education carries useful knowledge from the school/college to families; its steps are identifying needs, planning, executing, and evaluating change in behaviour.

Teaching aids for community work: charts, flash cards, flip books, posters, demonstrations, role play, puppets and street plays; choose the aid for the audience's literacy level.

A demonstration teaches by showing and telling: introduce the topic, show the method step by step, let learners practise, and summarise key points.

Nutrition education messages should be simple, locally worded and use local foods (millets, seasonal vegetables, curd) rather than unfamiliar or costly items.

Anganwadi and ICDS services include supplementary nutrition, pre-school education, immunisation, health check-ups and nutrition/health education for mothers.

Self-help groups enable small savings, micro-credit and collective enterprise; Home Science skills such as food processing, tailoring and craft can become group livelihood.

Home accidents are prevented by non-slip floors, safe storage of kerosene, medicines and pesticides, guarding stairs, and keeping sharp and hot items out of children's reach.

Waste-to-wealth projects: cloth bags from old fabric, paper bags, compost from kitchen waste, and reusable sanitary or household items.

Documentation of community work should record date, place, target group, activity, participation and outcome, so that it can be evaluated and repeated.

Viva questions often test definitions: balanced diet, food group, exchange list, resource, budget, development, hygiene, adulteration - answer with a definition plus one example.

Distinguish similar terms: jam vs jelly vs marmalade; staple vs protective food; growth vs development; fixed vs flexible expense; warp vs weft; boiling vs steaming.

Label reading: look for ingredient list, net weight, date of manufacture and best-before, FSSAI licence number, nutrition information and storage instructions.

Measurement conversions used in practicals: 1 cup ≈ 200 ml, 1 tablespoon ≈ 15 ml, 1 teaspoon ≈ 5 ml, 1 kg = 1000 g; use level, not heaped, measures for accuracy.

Costing a recipe: total cost = sum of (quantity used × unit price); cost per serving = total cost ÷ number of servings; compare with market price of a similar product.

Sensory evaluation of food uses appearance, colour, aroma, texture, taste and overall acceptability, scored on a simple scale such as 1–5 or 1–9.

Common practical faults and their cause: hard chapatis (kneading/resting too little), curdled milk on boiling (acid or old milk), stiff jam (over-boiling), skipped stitches (tension or needle fault).

Record-book marks depend on regularity, neatness, accuracy, diagrams and reflection; viva marks depend on clarity and correct use of technical terms.

Home Science integrates its areas in daily decisions: a family choosing a cheaper cereal, storing it safely, cooking it to retain nutrients and budgeting for it uses food, resource management and hygiene together.

Health is influenced by the interaction of diet, hygiene, housing, clothing and emotional relationships - not by any one factor alone.

Sustainable living choices: seasonal and local food, mending and reusing clothes, low-energy appliances, solar drying, composting and water harvesting.

Gender equity in the home: sharing of household work, equal education for girls, and recognition of unpaid care work are part of family resource management.

Consumer vigilance in daily life: comparing unit price, refusing adulterated or expired goods, insisting on a bill, and using the consumer commission if cheated.

Disaster and emergency readiness at home: stored water, torch, first-aid box, important documents in a waterproof cover, and a family meeting point.

Ageing family members need softer foods, calcium and vitamin D, safe flooring, good lighting, and social contact; young children need supervision, immunisation and play.

Home Science careers connect to national priorities: nutrition (Poshan Abhiyaan), sanitation (Swachh Bharat), child care (ICDS) and consumer protection.

ICDS (Integrated Child Development Services) delivers supplementary nutrition, immunisation, health check-up, referral, pre-school education and nutrition education through Anganwadi centres.

Mid-Day Meal (PM POSHAN) provides a cooked school meal to support attendance and nutrition; menu should supply about one-third of a child's daily energy and protein needs.

National programmes relevant to Home Science: Poshan Abhiyaan (nutrition), Anaemia Mukt Bharat (iron-folic acid, deworming), iodised salt promotion, and Swachh Bharat (sanitation).

ORS (oral rehydration solution) is the first-line treatment for dehydration from diarrhoea; zinc supplements are also recommended; continue feeding during diarrhoea.

Vitamin A supplementation is given to children at 9 months with the measles-rubella vaccine and then at fixed intervals up to 5 years.

Growth monitoring uses weight-for-age and height-for-age charts; a flat or falling growth curve signals a need for health-worker referral.

Adolescent health: iron-folic acid tablets, menstrual hygiene with clean absorbent and safe disposal, and awareness of nutrition for the growth spurt.

Food fortification adds micronutrients to staples - iodised salt, fortified wheat flour and rice, double-fortified salt with iron and iodine; fortification complements, not replaces, a balanced diet.

A practical file should be dated, titled, and written in the candidate's own words; copied text earns no credit and is easily detected.

Diagrams and flow charts (work triangle, food groups, growth chart, seam diagram) should be labelled, neat and to scale.

A recipe card format: name, ingredients with measures, method in numbered steps, time, servings, cost per serving and one nutrition note.

A survey report format: objective, sample and tool, findings in a table, interpretation, conclusion and one practical suggestion.

Oral presentation: open with the purpose, use 3–5 key points, show a sample or chart, and close with a summary; keep within the allotted time.

Evidence of work - photographs of the prepared dish, stitched article or chart, with a short caption - strengthens project evaluation.

Reflection section: state what was difficult, what was learnt, and what would be done differently; this shows applied understanding.

Group projects should record each member's contribution; assessment often includes both group output and individual understanding.

First aid aims to preserve life, prevent worsening and promote recovery until professional help arrives.

Burns: cool under running water for at least 10–20 minutes, cover with a clean non-fluffy cloth, do not apply oil, toothpaste or ice, and do not burst blisters.

Cuts and bleeding: wash hands, apply pressure with a clean cloth, raise the injured part, clean the wound and cover it; refer for deep or dirty wounds and check tetanus status.

Choking: encourage coughing; if the airway is blocked, give back blows and abdominal thrusts as taught; call for help immediately.

Fainting: lay the person flat, raise the legs, loosen tight clothing, ensure fresh air and do not pour water into the mouth.

Electric shock: switch off the current before touching the person, then check breathing and call for help; never touch with bare wet hands.

Poisoning: do not induce vomiting unless advised; keep the container and take the person to a health facility with it.

Kitchen safety: turn pot handles inward, keep a lid or wet cloth to smother a pan fire, never pour water on an oil fire, and keep children away from hot surfaces.

A home first-aid box should contain sterile gauze, adhesive plasters, cotton, antiseptic, ORS, paracetamol, scissors, tweezers, a thermometer and a list of emergency numbers.

Unit price comparison: divide the price by the quantity (per gram, per ml) to compare differently sized packs; the larger pack is not always cheaper per unit.

A cash memo is the main proof of purchase; without it, a consumer complaint is much harder to establish.

Labels must state name and address of manufacturer, net quantity, ingredients, date of manufacture, best-before/use-by, and FSSAI licence number for food.

Food adulteration is adding a cheaper or harmful substance to food; common tests use iodine (starch), hydrochloric acid (metanil yellow), and water (chalk in flour).

Sale of goods: check the return/exchange policy before buying, keep the warranty card, and note that 'no exchange on sale items' must be disclosed before purchase.

Online buying risks: fake reviews, misleading photos, hidden delivery charges; pay by traceable mode and keep screenshots of the order.

Banking basics for families: savings account, recurring deposit for planned goals, and the importance of not sharing PIN/OTP with anyone.

Advertising literacy: identify the persuasion technique (fear, celebrity, bandwagon, free gift) and ask whether the product meets a real need within the budget.

Consumer complaint steps: approach the seller, then the manufacturer/consumer helpline, then the District Consumer Commission with bill and proof.

Gelatinisation: starch granules absorb water and swell on heating, thickening the liquid; cooling sets it into a gel (e.g. custard, halwa).

Dextrinisation: dry heat converts starch to dextrins, giving brown colour and flavour to toast, roasted grains and browned flour.

Caramelisation: sugar melts and browns on heating; overheating gives a bitter taste.

Coagulation: proteins set on heating (egg, paneer); adding acid (lemon) or salt speeds coagulation of milk protein.

Emulsification: an emulsifier (egg yolk lecithin, mustard) holds oil and water together, as in mayonnaise.

Leavening agents: yeast (biological, produces carbon dioxide by fermentation), baking powder and soda (chemical), and air/steam (physical) make dough rise.

Effect of acid on vegetables: acids (tamarind, lemon) firm up pectin and slow softening; alkalis make vegetables mushy and destroy vitamins.

Enzymatic browning: cut fruits such as apple and brinjal darken due to polyphenol oxidase; dipping in salt water, lemon juice or blanching slows it.

Smoke point: oil heated beyond its smoke point breaks down, gives off-flavour and harmful compounds; do not reuse oil repeatedly.

Washing steps: sorting, mending, stain removal, soaking (short), washing, rinsing, starching (optional), drying and ironing/folding.

Soaps are sodium salts of fatty acids (alkaline); detergents work in hard water and are available for delicate fabrics; hard water wastes soap and leaves scum.

Starching gives crispness and body to cotton; use thin starch for light fabrics and thick for collars and cuffs.

Ironing temperatures: cotton high, linen high, wool medium with a damp cloth, silk low, synthetics low; a hot iron melts polyester and glazes wool.

Shrinkage is highest in cotton and rayon; pre-shrink fabric by washing before cutting, or buy extra length.

Darning repairs holes by weaving threads across the hole; patching is used for larger holes, and a neat patch matches grain and colour.

Buttons, hooks and press studs are fasteners; buttonholes should be worked with matching thread and reinforced at the ends.

Storage of clothes: clean and dry before storing, use neem or dried herbs against insects, avoid naphthalene directly touching woollens, and air woollens before storing.

Readymade garment fit: check shoulder seam position, ease at bust/hip, sleeve length and hem; alterations are limited by seam allowance.

Weaning foods should be soft, semi-solid, single-ingredient at first, and introduced one at a time to detect allergy; start around 6 months alongside breastfeeding.

Common childhood illnesses and signs: diarrhoea (dehydration - use ORS), fever, cough and cold, ear discharge, skin rash; danger signs need immediate referral.

Discipline should be consistent, explain the reason, and use withdrawal of privileges rather than physical punishment; punishment teaches fear, not understanding.

Language development: cooing, babbling, first words around 1 year, two-word sentences around 2 years, and rapid vocabulary growth in early childhood.

Toilet training is possible when the child shows readiness - dry nappies for a stretch, ability to sit, and interest - usually between 2 and 3 years.

Play materials for young children should be safe (no small parts, non-toxic paint), simple, and suited to the child's stage rather than expensive.

Teething usually begins around 6 months; clean gums and first teeth with a soft cloth or brush and avoid sweetened bottles at bedtime.

First aid for a child: keep calm, assess breathing, control bleeding, and never give medicines without advice; keep poison control and doctor numbers handy.

A good house plan provides light and ventilation (window area about one-fifth of floor area is a common guide), privacy, storage and safe circulation.

Kitchen types: one-wall, two-wall (corridor), L-shaped, U-shaped and island; the U-shape suits large kitchens, the one-wall suits small flats.

Ventilation may be natural (windows, ventilators) or mechanical (exhaust fan, chimney); a kitchen chimney removes smoke and grease.

Floor coverings: durries and carpets add warmth and absorb sound; washable mats suit kitchens and bathrooms.

Curtain types: pleated, café, roman and roller; heavier, lined curtains give privacy and insulation, sheer curtains admit light.

Lighting types: general (ceiling), task (study lamp, kitchen counter), and accent (decorative); use energy-efficient lamps.

Colour scheme choice depends on room size, light, function and user preference; a small dark room benefits from light, cool colours.

Furniture arrangement should keep doorways and passages clear, place the bed away from draughts, and group seating for conversation.

Home safety: non-slip bathroom flooring, grab bars for the elderly, covered electrical sockets for children, and clear stairways.

Lifestyle diseases - obesity, type 2 diabetes, hypertension and heart disease - are linked to excess energy intake, fried and sugary foods, and physical inactivity.

Body Mass Index (BMI) = weight in kg ÷ (height in metres)²; under 18.5 is underweight, 18.5–24.9 normal, 25–29.9 overweight, 30 and above obese (adult Asian cut-offs are often lower).

Obesity management: reduce energy-dense foods, increase fibre (whole grains, vegetables), exercise regularly, and avoid crash diets.

Diabetes diet: regular meal timing, complex carbohydrates, high fibre, limited refined sugar and sweets, and monitoring as advised by a doctor.

Hypertension: limit salt and pickles/papads, avoid smoking and excess alcohol, maintain weight and exercise; salt restriction is central.

Anaemia prevention: iron-rich foods (green leafy vegetables, jaggery, liver, pulses), vitamin C to aid iron absorption, and avoiding tea with meals as it inhibits iron absorption.

Smoking, tobacco chewing, alcohol and substance use are major preventable health risks; awareness and refusal skills are part of health education.

Physical activity for adolescents: at least 60 minutes of moderate activity daily; for adults, about 150 minutes a week of moderate activity is advised.

Mental health: adequate sleep, supportive relationships, and seeking help for persistent sadness or anxiety are part of overall health.

Safe water supply at home: protected source, storage in a covered container with a tap, cleaning the container regularly, and treating water before drinking.

Excreta-related diseases (cholera, typhoid, dysentery, worm infestation) are prevented by toilets, handwashing with soap and safe water.

Mosquito control: empty stagnant water from coolers, pots and tyres; cover water storage; use nets and screens; dengue and malaria mosquitoes breed in clean stagnant water.

Air pollution at home comes from chulhas, open burning and poor ventilation; a smokeless chulha or LPG with a chimney reduces indoor smoke.

Waste management hierarchy: prevent, reduce, reuse, recycle, recover (compost/energy), and dispose as the last option.

Plastic waste: avoid single-use plastic, carry cloth bags, segregate and give plastic for recycling; burning plastic releases toxic fumes.

E-waste (old phones, batteries, chargers) should be given to authorised collection points, not mixed with kitchen waste.

Noise pollution harms hearing and concentration; keep loudspeakers and TV volume low and observe silence zones.

Green practices at home: grow plants on balconies, harvest rainwater, use natural light, and repair rather than discard.

Portfolio building: collect recipes, stitched samples, charts, survey reports and photographs; a portfolio demonstrates skill at interviews and admissions.

Self-employment costing: add material cost, labour, overheads and a margin to fix a price; keep a simple record of sales and expenses.

Hygiene and licensing for a home food business: clean premises, safe water, trained handling, correct labelling and FSSAI registration.

Customer service basics: clear communication, keeping promises about quality and delivery, and handling complaints politely.

Communication skills for extension work: speak in the local language, use examples, invite questions, and check understanding by asking the learner to repeat or demonstrate.

Interview and application readiness: know the job's requirements, prepare examples of practical work, and keep certificates and portfolio ready.

Digital skills: use a smartphone for price comparison, online banking safely, and sharing information; verify before forwarding messages.

Teamwork and time management in group projects: divide work by skill, set deadlines, and record individual contributions.

Ethics in applied work: honesty in reporting, respect for privacy in child and family studies, and no exaggeration of product claims.

Read the whole paper first, mark questions you know, and allocate time by marks - a 5-mark question needs more points than a 1-mark question.

Definition questions need a precise one- or two-line definition plus one example; avoid vague wording.

Difference questions need a two-column table with paired points on the same basis (e.g. natural vs man-made fibres: origin, absorbency, strength).

Reason questions ('Why is soda not added to vegetables?') need a cause-and-effect answer: soda destroys vitamin C and thiamine, so nutrient value falls.

Diagram questions need a labelled, neat diagram and a one-line caption; label in pencil and write labels horizontally.

Practical-viva preparation: revise definitions, unit conversions, food-group classification, first-aid steps and fabric-care symbols.

Time-saving revision: make one-page summaries per domain, use mnemonics for lists (food groups, deficiency diseases), and practise past-paper question types.

Common mark-losing errors: unlabelled diagrams, answers without examples, mixing up deficiency diseases, and ignoring the marks allotted.

In practical exams, keep the work area clean, follow safety, present neatly, and be able to explain each step you performed.

Cereals and millets (wheat, rice, maize, bajra, ragi) are the main energy source, supplying carbohydrate, some protein, B vitamins and fibre; whole grains retain more fibre.

Pulses and legumes (dal, gram, rajma, soyabean) are the main plant protein source and also supply iron, calcium and B vitamins.

Milk and milk products supply good-quality protein, calcium, riboflavin and vitamin A (in whole milk); curd is easier to digest and helps gut flora.

Meat, fish, eggs and poultry supply complete protein, iron, zinc and B vitamins; egg white is a reference protein.

Green leafy vegetables supply iron, calcium, carotene (vitamin A precursor), vitamin C and fibre; darker leaves are richer.

Yellow and orange fruits and vegetables (carrot, papaya, mango, pumpkin) are rich in carotene; citrus fruits (orange, amla, guava) are rich in vitamin C.

Fats and oils (ghee, mustard oil, groundnut oil) supply essential fatty acids and help absorb fat-soluble vitamins; excess adds energy.

Sugar and jaggery supply energy only; jaggery retains some minerals but is still a concentrated sugar and should be limited.

Iodised salt supplies iodine; use it in moderation and add near the end of cooking to retain iodine.

Drying is the oldest method; vegetables and fruits are blanched, dried in sun or a dehydrator, and stored in airtight containers away from moisture.

Pickling uses salt, oil, acid (vinegar or lemon) and spices; the acid and salt inhibit microorganisms; use dry spoons and keep the surface covered with oil.

Jam, jelly and marmalade need pectin, acid and sugar; fruits low in pectin (strawberry) need added pectin, while citrus and apple are rich in it.

Squash and syrup are preserved fruit juices with sugar and preservative (sulphur dioxide or sodium benzoate in permitted amounts); store in sterilised bottles.

Canning requires sterilising jars, filling hot, exhausting air, sealing and heat processing; a failed seal or bulging lid means spoilage - discard.

Freezing slows microbial growth but does not kill microorganisms; blanch vegetables first, pack airtight and thaw in the refrigerator, not at room temperature.

Refrigerator storage: cooked food above raw meat, covered containers, do not overload, and keep the temperature between 1 and 4 °C.

Dry storage: cool, dark, ventilated place, airtight containers, rotation of older stock to the front, and protection from insects and rodents.

Signs of spoilage: off smell, slime, mould, gas, changed colour or texture; never taste to check - discard.

Communication has a sender, message, channel, receiver and feedback; barriers include assumptions, unclear words, emotions and poor listening.

Active listening means giving attention, not interrupting, asking questions and reflecting back what was heard.

Conflict resolution steps: stay calm, state the issue without blame, listen to the other side, look for options, agree and review.

Parenting styles: authoritarian (strict, little explanation), authoritative (firm with explanation and warmth - usually most effective), permissive (few limits), uninvolved.

Sibling relationships teach sharing, negotiation and fairness; parents should avoid comparisons and give each child some individual attention.

Care of the elderly in the family: respect, inclusion in decisions, help with health needs, and attention to loneliness.

Adolescent–parent communication improves with open questions, respect for privacy, consistent rules and shared meals.

Family crises (illness, financial loss, death) need honest communication suited to the child's age, reassurance and routine.

Gender-fair practices at home: shared chores, equal schooling, and equal say in decisions benefit family well-being.

Metric units: 1 kg = 1000 g, 1 litre = 1000 ml, 1 metre = 100 cm; use the unit asked for and show the working.

Standard measures: 1 cup ≈ 200 ml, 1 tablespoon ≈ 15 ml, 1 teaspoon ≈ 5 ml; level measures give repeatable results.

Percentage: part ÷ whole × 100; used for nutrient contribution, budget share and wastage.

Cost per serving = total ingredient cost ÷ number of servings; compare with the market price of a similar ready product to judge economy.

Budget balance: total income = total expenditure + savings; if expenditure exceeds income, cut flexible expenses first.

BMI = weight (kg) ÷ height (m)²; convert height in cm to metres before calculating.

Energy contribution: multiply grams of nutrient by its kilocalorie value (carbohydrate 4, protein 4, fat 9) to find the energy from each.

Fabric requirement ≈ length of garment + sleeve length (if cut separately) + seam allowance + shrinkage allowance; check against the pattern envelope.

Time planning: list tasks, estimate time, set priorities, and add a buffer; compare planned with actual time to improve next time.

Anganwadi centre provides supplementary nutrition, pre-school education, health check-ups and nutrition education for pregnant women and children under six.

ASHA worker links the community with the health system - antenatal care, immunisation, ORS and referral advice.

Panchayat and municipal bodies manage water supply, sanitation, drainage, street lighting and waste collection.

Schools, libraries and youth clubs provide learning, recreation and awareness activities; Home Science students can conduct extension activities through them.

Self-help groups and cooperatives offer savings, credit and collective marketing for home-based enterprises.

Consumer helpline and District Consumer Commission provide redressal; keep the bill and proof of complaint.

Police, fire service, ambulance (108-type emergency numbers) and hospital contacts should be displayed at home and in school.

NGOs and voluntary organisations support nutrition, sanitation and child welfare projects; students can volunteer or survey with them.

Balanced diet: a diet that supplies all nutrients in the required amounts and proportions for a person's age, sex and activity, with some extra for fibre and water.

Food group: a set of foods with similar nutrient composition, grouped so that a balanced diet can be planned and exchanged within the group.

Adulteration: the addition of a cheaper, inferior or harmful substance to food to increase quantity or improve appearance; detected by simple chemical tests.

Preservation: treating food to stop or slow spoilage so it can be stored and used later, by removing moisture, heat, cold, acid, salt, sugar or air.

Development: progressive change in the child's capacity and behaviour over time; growth is increase in size or weight, a part of development.

Resource: anything used to achieve a goal; human resources are within the person, non-human resources are material and environmental.

Marks are commonly given for accuracy, neatness, hygiene, safety, time management, use of local and economical materials, and viva answers.

Common deductions: missing conclusion, unlabelled diagram, unmeasured ingredients, untidy work area, unsafe handling of hot or sharp items.

Keep a rough notebook for observations in the practical room and write the fair record neatly afterwards.

FSSAI is the food safety regulator; packaged food must carry its licence number, and consumers can complain about unsafe or mislabelled food.

Food fortification adds vitamins and minerals to staples; fortified rice and wheat flour, iodised salt and double-fortified salt are common examples.

Poshan Abhiyaan aims to reduce malnutrition, anaemia and low birth weight through convergence of nutrition services and behaviour change.

Anaemia Mukt Bharat targets anaemia through iron-folic acid supplementation, deworming, fortified foods and testing.

ORS and zinc are promoted for childhood diarrhoea; continued feeding and fluids prevent malnutrition during illness.

Vitamin A supplementation and deworming are part of child health services delivered through schools and Anganwadi centres.

Mid-day meal guidelines require a hot cooked meal, hygiene in cooking and serving, and a varied menu with local foods.

Food safety at home: separate raw and cooked food, cook thoroughly, keep food at safe temperatures, use safe water and raw materials.

Consumer can report food adulteration to the local food safety office with a sample and receipt.

Fibre identification tests: burning test (smell and ash), feel test, and solubility test; cotton smells of paper, wool and silk of burnt hair, synthetics melt into a bead.

Yarn count and twist affect fabric strength and texture; higher twist gives a smoother, stronger yarn.

Warp threads run lengthwise, parallel to the selvedge; weft threads run across; the bias is at 45° and stretches most.

Fabric finishes: mercerisation (cotton, adds lustre and strength), calendering (smooth surface), sanforisation (controls shrinkage), water-repellent and flame-retardant finishes.

Dyeing and printing: dyeing colours the whole fabric, printing applies colour in patterns; fastness to washing and light determines quality.

Basic pattern symbols: grain line, fold line, notch, dart, buttonhole and seam allowance line; cutting on the fold gives a symmetrical piece.

Seam allowance is usually 1–1.5 cm; clip curves and trim corners before turning to get a smooth shape.

Care symbols: washtub (washing), triangle (bleaching), square with circle (drying), iron (ironing temperature), circle (dry cleaning).

Wardrobe planning: choose clothes that mix and match, suit the climate and occasion, and fit the budget; mend promptly to extend life.

Work simplification reduces fatigue by better arrangement: store frequently used items within easy reach, group similar tasks, and use both hands.

Kitchen work triangle: the three sides should total roughly 4–8 metres for efficient movement; obstacles inside the triangle increase steps.

Standard counter height is about 85 cm, with the work surface slightly lower for tall users and higher for short users to avoid stooping.

Storage principles: store at the point of first use, keep heavy items low, keep frequently used items at eye-to-hand level, and label containers.

Zoning at home: separate noisy (kitchen, living) from quiet (study, bedroom) areas and keep the toilet away from the kitchen.

Space-saving furniture: bunk beds, folding tables, wall-mounted shelves, and storage under the bed or stairs.

Good lighting reduces eye strain; place study lamps on the opposite side of the writing hand to avoid shadow.

Ventilation and cross-ventilation reduce humidity, smoke and odours; a kitchen must have an exhaust or window.

Home maintenance: check taps for leaks, whitewash regularly, repair cracks, and keep drains clear to prevent mosquitoes and dampness.

Six consumer rights: safety, information, choice, being heard, redressal and consumer education; later additions include the right to a healthy environment.

Consumer Protection Act, 2019 covers goods and services, e-commerce, and misleading advertisements; it provides for product liability and unfair trade practice penalties.

Three-tier redressal: District Commission (lower value claims), State Commission (appeals and higher value), and National Commission (highest value and appeals).

A complaint should state the facts, the loss or injury, the relief sought, and attach the bill, warranty, photographs or correspondence.

A cash memo, warranty card, guarantee and label are the consumer's evidence; keep them until the product is used up.

Misleading advertisement claims can be complained about to the regulator; exaggerated health claims about food are a common example.

Jago Grahak Jago is a consumer awareness initiative; the national consumer helpline assists with complaints.

Standardisation marks: ISI for industrial goods, FSSAI for food, Agmark for agricultural produce, Hallmark for gold, and Ecomark for environment-friendly products.

Wise buying steps: identify the need, gather information, compare brands and unit prices, check the label and mark, buy, and keep the proof.

Physical growth: birth weight doubles by about 5 months and triples by 1 year; height increases by about 50 per cent in the first year.

Social smile appears around 6–8 weeks; stranger anxiety around 7–9 months; parallel play in toddlers; cooperative play in early childhood.

Language: crying and cooing in the first months, babbling at 6–9 months, first meaningful word around 1 year, two-word phrases around 2 years.

Cognitive development in early childhood is marked by symbolic play, curiosity, short attention span and egocentric thinking.

Emotional development: attachment to the mother or caregiver in infancy, temper tantrums in toddlers, and growing self-control in later childhood.

Nutrition for the young child: breast milk up to 6 months, complementary foods from 6 months, family food by 1–2 years, small frequent meals and no force feeding.

Immunisation and growth monitoring at the Anganwadi centre protect the child; keep the immunisation card safe.

Care of the child with diarrhoea: give ORS and zinc, continue feeding and breastfeeding, and seek help for blood in stool or persistent vomiting.

Safety at home for the child: gate the stairs, cover sockets, keep medicines and sharp objects out of reach, and supervise water play.

Segregate waste at home into wet (biodegradable), dry (recyclable) and hazardous (batteries, medicines, sanitary waste).

Composting needs a mix of green (kitchen waste) and brown (dry leaves, paper), moisture, air and time; turning the pile speeds decomposition.

Vermicomposting uses earthworms to convert organic waste into nutrient-rich manure; keep the bed moist and shaded.

Rainwater harvesting collects roof water into a tank or recharge pit; it reduces dependence on groundwater and prevents flooding.

Water conservation at home: fix leaks, use a bucket instead of a running tap, reuse vegetable-washing water for plants, and cover stored water.

Energy conservation: switch off unused lights and fans, use LED bulbs, use solar water heaters, and keep refrigerators away from heat sources.

Tree planting and care: choose local species, water regularly, protect saplings, and avoid cutting trees; trees reduce dust, heat and noise.

Avoid open burning of waste and crackers; it releases harmful gases and worsens air pollution.

Community action: cleanliness drives, awareness rallies, school eco-clubs and plastic-free campaigns involve families in environmental improvement.

Menu planning for a family of four: include cereal, pulse, vegetable, milk product and fruit across the day; keep one seasonal vegetable and one fruit for economy.

Packing a balanced tiffin: a cereal staple, a protein item, a vegetable or fruit, and water; avoid too much oil, sugar or packaged snacks.

Safe food handling: wash hands and utensils, keep raw and cooked food separate, cook thoroughly, store at safe temperature, and use safe water.

Kitchen first aid: cool a burn with running water, cover a cut with a clean cloth, and never apply toothpaste or oil to a burn.

Stain removal at home: cold water for blood and egg, detergent for grease, lemon and salt for rust or ink, and sunlight for mildew on cotton.

Mending and repair: stitch a tear promptly, replace missing buttons, darn holes in socks and elbows, and repair hems to extend garment life.

Budget for a small family: list fixed expenses first, then flexible; set aside savings and an emergency fund before spending on wants.

Home cleaning routine: sweep and mop daily in the kitchen, clean the toilet with disinfectant, wash dustbins, and air bedding in sunlight.

Emergency kit: torch, first-aid box, ORS, candles, matches, drinking water, important documents and a list of emergency numbers.

WHO definition of health: a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.

Energy values: carbohydrate 4 kcal/g, protein 4 kcal/g, fat 9 kcal/g; alcohol supplies about 7 kcal/g but is not a nutrient.

Adult BMI categories: underweight below 18.5, normal 18.5–24.9, overweight 25–29.9, obese 30 and above (WHO adult cut-offs).

Colostrum is the first thick yellowish milk, rich in antibodies (immunoglobulin A) and should be given to the newborn within the first hour.

Exclusive breastfeeding is recommended for the first 6 months; complementary feeding starts at 6 months and breastfeeding continues up to 2 years.

ORS is a mixture of salt and sugar in water that replaces water and electrolytes lost in diarrhoea; zinc is given along with it.

Standard marks: ISI (BIS) for industrial goods, FSSAI for food, Agmark for agricultural produce, Hallmark for gold.

Consumer Protection Act, 2019 replaced the 1986 Act and covers e-commerce and product liability.

3Rs of waste management: reduce, reuse, recycle; the wider hierarchy adds refuse and rot (compost) before recycle.

Knife cuts and their use: slicing for even cooking, dicing for salads and stuffings, chopping for gravies, and julienne for garnishes.

Methods of cooking with examples: boiling (rice), steaming (idli), pressure cooking (dal), shallow frying (paratha), deep frying (pakora), baking (cake), roasting (chana).

Advantages of pressure cooking: saves fuel and time, retains more water-soluble vitamins, and cooks pulses and tough meats quickly.

Sprouting increases vitamin C, improves digestibility and reduces anti-nutrients in pulses; germinate in a moist, clean cloth and use fresh.

Fermentation (curd, idli, dhokla) improves digestibility, adds B vitamins and beneficial bacteria; use a clean starter and warm conditions.

Basic hand stitches: running (gathering, tucking), back (strong seams), hemming (neat edges), blanket (edges of blankets), chain (decoration), buttonhole.

Seam types: plain (simple, needs finishing), French (neat, for light fabrics), run-and-fell (strong, for children's clothes and jeans).

Home cleaning agents: soap and detergent for grease, acid (lemon, vinegar) for hard water stains, bleach for disinfection (use with care and never mix with acid).

Fire safety at home: keep a bucket of sand or a fire extinguisher in the kitchen, never pour water on an oil fire, and turn off the gas after cooking.

Nutrition education aims at behaviour change, not just knowledge; use local foods, demonstrations, and repeated messages.

Growth charts plot weight or height for age; a child below the line or with a falling curve needs assessment and referral.

Nutritional assessment methods: dietary survey (24-hour recall, food frequency), anthropometry (weight, height, MUAC), clinical examination and biochemical tests.

Mid-upper arm circumference (MUAC) is a quick field measure of wasting in children; a coloured tape classifies the child.

Common nutritional problems in India: protein-energy malnutrition, iron-deficiency anaemia, vitamin A deficiency, iodine deficiency disorders and obesity in urban areas.

Dietary guidelines recommend plenty of vegetables and fruits, whole grains and millets, limited fat, sugar and salt, and adequate water.

Food-based approaches to malnutrition: kitchen gardens, poultry and dairy, inclusion of millets and pulses, and improved cooking practices.

Health education on hygiene: handwashing with soap at five critical times - after toilet, after cleaning a child, before food preparation, before eating, and before feeding a child.

Community participation makes programmes work: involve mothers' groups, school children and local leaders in planning and monitoring.

Goal setting: distinguish short-term (a school bag), medium-term (a cycle) and long-term (a house) goals; plan savings accordingly.

Money management steps: record income, list expenses, prepare a budget, keep accounts, review monthly and adjust.

Time savers at home: plan the day, combine tasks (soak dal while preparing vegetables), use pressure cooker and mixie, and share work among family members.

Energy savers: sit for long tasks, keep frequently used items at waist height, use a trolley, and avoid unnecessary trips.

Decision-making in purchase: compare brands, check unit price, read the label, consider durability and after-sales service, and avoid impulse buying.

Consumer aids: cash memo, warranty card, guarantee, standardisation marks, and the consumer helpline.

Resource substitution: use time for money (cook at home instead of buying), or money for time (buy a labour-saving appliance) depending on which is scarcer.

Family budget shares: food, housing, education, health, clothing, transport and savings; needs come before wants, and savings are a planned item.

Records help: keep bills, bank passbook, insurance papers and a simple account book; review insurance and savings annually.

Orientation: in hot climates, the longer walls face north-south and the shorter walls east-west to reduce heat gain; verandahs and sunshades protect windows.

Ventilation rate depends on window area, position and openings on opposite sides; a ventilator near the ceiling removes hot air.

Kitchen planning: place the sink near the preparation area, the cooking range near the window or chimney, and storage near the work centres.

Bathroom planning: non-slip flooring, proper drainage slope, ventilation, and a water source away from the kitchen.

Bedroom planning: quiet location, cross-ventilation, storage for clothes, and a bed away from direct draughts and bright light.

Living room furnishing: group seating for conversation, leave circulation space, and use a focal point such as a window or artwork.

Curtain selection depends on privacy, light control, room size and washability; lined curtains give privacy and insulation.

Floor coverings: small rugs define areas in a large room; washable mats suit kitchens and bathrooms.

Home safety for children and elderly: stair rails, non-slip mats, adequate lighting, and no loose wires or low-hanging cords.

Personal hygiene includes bathing daily, brushing teeth twice a day, washing hair regularly, trimming nails, and wearing clean clothes.

Handwashing with soap removes germs; the five critical times are after toilet, after cleaning a child, before cooking, before eating and before feeding a child.

Menstrual hygiene: use clean absorbent, change every 4–6 hours, wash with clean water, and dispose of used pads wrapped in paper in a covered bin.

Oral hygiene: brush twice daily with fluoride toothpaste, rinse after sweets, and visit a dentist for persistent pain or bleeding gums.

Foot care: wash and dry feet daily, wear clean cotton socks, cut nails straight across, and wear well-fitting footwear to prevent infection.

Safe water: boil, filter or chlorinate; store in a covered container with a tap and clean it regularly.

Food hygiene: wash hands and produce, cook thoroughly, keep cooked food covered, and avoid eating from unhygienic street vendors.

Cough and sneeze etiquette: cover mouth and nose with a handkerchief or elbow, and wash hands afterwards.

Sleep and rest: adolescents need about 8–9 hours of sleep; regular sleep improves concentration and health.

Washtub symbol with a number gives the maximum washing temperature; a hand in the tub means hand wash only; a cross means do not wash.

Triangle symbol: empty means any bleach allowed, crossed means no bleach, and diagonal lines mean only oxygen bleach.

Square symbol: a circle inside means tumble dry; dots indicate heat level; a line means line dry; a crossed square means do not dry.

Iron symbol: dots indicate temperature - one dot low (synthetics), two dots medium (wool, silk), three dots high (cotton, linen).

Circle symbol: dry clean only; a letter inside indicates the solvent; a crossed circle means do not dry clean.

Washing sequence: sort by colour and fabric, mend first, treat stains, soak briefly, wash, rinse well, dry in shade for colours, iron and fold.

Soap vs detergent: soap is alkaline and forms scum in hard water; detergent works in hard water and rinses easily.

Stain removal: cold water for blood and egg, absorbent powder for grease, lemon and salt for rust, and alcohol for ink; test on a hidden part.

Storage: clean and dry clothes, use neem leaves against insects, air woollens, and avoid naphthalene touching the fabric directly.

Play is essential for physical, cognitive, language, social and emotional development; it is the child's natural way of learning.

Types of play by age: solitary (infants), parallel (toddlers), associative and cooperative (preschool and older children).

Play materials should be safe, non-toxic, age-appropriate, simple and varied; homemade toys from safe waste material encourage creativity.

Outdoor play develops large muscles, coordination and social skills; indoor play develops fine muscles, imagination and language.

Storytelling and rhymes build vocabulary, listening and imagination; ask simple questions afterwards.

Free play allows the child to choose and explore; guided play adds adult support without taking over.

Television and mobile screens should be limited; too much screen time reduces active play and interaction.

Play and disability: adapt toys and games so children with different abilities can join; inclusive play builds empathy.

Adults should supervise, provide safe space and materials, and allow the child to solve problems rather than doing it for them.

Why should vegetables not be overcooked? Heat and water destroy vitamin C and B vitamins; minimal water and short cooking retain them.

Why is dal-rice a good combination? Cereal protein is low in lysine, pulse protein is low in methionine; together they give a better amino acid balance.

Why is vitamin C taken with iron-rich foods? Vitamin C converts iron to a more absorbable form and improves absorption from plant foods.

Why should tea not be taken with meals? Tannins in tea bind iron and reduce its absorption; take tea between meals.

Why is iodised salt added at the end of cooking? Iodine is lost on prolonged heating; add salt near the end and store in a closed container.

Why is colostrum important? It is rich in antibodies, proteins and vitamin A and protects the newborn from infection.

Why is ORS given in diarrhoea? It replaces water and electrolytes lost, preventing dehydration; continue feeding too.

Why is a balanced diet important for adolescents? Rapid growth and activity increase needs for energy, protein, iron and calcium; deficiencies affect growth and learning.

Why is fibre important? It prevents constipation, helps control blood sugar and cholesterol, and adds bulk to the diet.

Define and give one example for: balanced diet, food group, exchange list, adulteration, preservation, resource, budget, development, hygiene, sanitation.

Distinguish: growth vs development; jam vs jelly; staple vs protective food; fixed vs flexible expense; warp vs weft; boiling vs steaming; soap vs detergent.

Know the food groups and one rich source of each major nutrient: protein (pulse, milk, egg), iron (green leafy vegetables, jaggery), calcium (milk, ragi), vitamin C (amla, guava), vitamin A (carrot, papaya).

Know first-aid steps for burns, cuts, choking, fainting, electric shock and poisoning, and when to refer to a doctor.

Know standard marks and their products: ISI, FSSAI, Agmark, Hallmark, Ecomark.

Know the five critical times for handwashing and the steps of safe water treatment.

Know basic measurements: 1 cup ≈ 200 ml, 1 tablespoon ≈ 15 ml, 1 teaspoon ≈ 5 ml, 1 kg = 1000 g.

Know the consumer rights and the three-tier redressal under the Consumer Protection Act, 2019.

Be ready to explain each step of your practical work and why you chose the materials or method.

Textile and fashion careers include design, merchandising, quality control, apparel production and boutique entrepreneurship.

Child development careers include preschool teaching, Anganwadi supervisor, crèche and day-care management, and child counselling with further training.

Interior design and home furnishing careers need knowledge of space planning, materials, colour and drafting.

Extension and community careers include nutrition educator, health worker, NGO programme officer and rural development roles.

Teaching careers need B.Ed. after graduation; Home Science is taught at school and college level.

Entrepreneurship options include tiffin service, bakery, tailoring, day-care, interior consultancy and food preservation units.

Adulteration is adding a cheaper, inferior or harmful substance to food to increase quantity or improve appearance; it can cause illness.

Starch in milk: add a few drops of iodine solution; a blue-black colour indicates starch.

Metanil yellow in turmeric: add a few drops of hydrochloric acid; a pink or magenta colour indicates the dye.

Chalk or stone powder in flour: add dilute hydrochloric acid; effervescence (bubbles) indicates chalk.

Water in milk: a drop of milk on a sloping surface runs down quickly if watery; the lactometer reading falls below the normal range.

Artificial colour in sweets and vegetables: wash with water or rub with a cotton swab soaked in water; colour coming off indicates artificial dye.

Ergot in bajra or wheat: black, elongated grains are visible on inspection.

Buying safe food: check the FSSAI licence number, date of manufacture, best-before date, and seal; avoid loose, uncovered food from unhygienic places.

Report adulteration to the local food safety office with a sample and receipt; the consumer can also use the national consumer helpline.

A healthy house provides light, ventilation, safe water, sanitary facilities, protection from heat, cold, rain and insects, and space for family activities.

Overcrowding spreads infection and stress; adequate floor area per person is a basic health requirement.

Dampness in walls and floors promotes mould and mosquitoes; fix leaks, improve ventilation and repair cracks.

Safe excreta disposal: use a sanitary toilet, keep it clean, and ensure the soak pit or sewer connection works; open defecation spreads disease.

Drainage: waste water should flow away from the house through covered drains to prevent mosquito breeding and bad odour.

Garbage: use covered bins, segregate at source, and dispose of waste daily; do not let water collect in discarded containers.

Indoor air pollution from chulhas and smoke harms the eyes and lungs; use a smokeless chulha, LPG or a chimney.

Vector control: empty and scrub water containers weekly, cover water storage, use nets and screens, and keep surroundings free of stagnant water.

Noise and light pollution affect health; keep volume low and use task lighting rather than glare.

Budget steps: estimate income, list fixed and flexible expenses, allocate for savings and emergencies, spend, record, and compare actual with planned.

Fixed expenses are regular and hard to change (rent, fees, insurance); flexible expenses can be adjusted (food, clothing, recreation).

Savings should be treated as a planned expense; a recurring deposit or small monthly saving builds an emergency fund.

Unit price comparison: divide price by quantity to compare packs of different sizes; the larger pack is not always cheaper per unit.

Impulse buying is unplanned buying triggered by display, sale or advertisement; a shopping list and a waiting period reduce it.

Advertisement techniques: glamour, repetition, celebrity endorsement, bandwagon appeal, free gifts and fear appeal.

Consumer rights: safety, information, choice, being heard, redressal and consumer education.

Complaint steps: approach the seller, then the manufacturer or consumer helpline, then the District Consumer Commission with the bill and proof.

Standard marks: ISI, FSSAI, Agmark, Hallmark, Ecomark; check the mark before buying.

Body measurements: bust/chest, waist, hip, shoulder width, sleeve length, back length and garment length; take over fitted clothing with the tape snug but not tight.

Seam allowance is usually 1–1.5 cm; clip curves and trim corners before turning for a smooth finish.

Basic hand stitches: running, back, hemming, blanket, chain and buttonhole; basic seams: plain, French and run-and-fell.

Fabric choice depends on purpose, climate, durability, washability, cost and the user's preference.

Fibre identification: burning test (paper smell for cotton, burnt hair for wool and silk, melting bead for synthetics), feel and solubility tests.

Care labels: washtub, triangle, square, iron and circle symbols give washing, bleaching, drying, ironing and dry-cleaning instructions.

Stain removal: cold water for blood and egg, absorbent powder for grease, lemon and salt for rust or ink, and alcohol for ink; test first.

Clothing selection considers climate, occupation, age, figure, fashion, durability, comfort and budget.

Five critical times for handwashing: after toilet, after cleaning a child, before cooking, before eating, before feeding a child.

Safe water: boil for 1–2 minutes after the rolling boil, or chlorinate with the correct dose, or filter; store covered with a tap.

Sanitation: use a toilet, keep it clean, ensure safe excreta disposal, and avoid open defecation to prevent diarrhoea, typhoid and worm infestation.

Waste segregation: wet (biodegradable), dry (recyclable) and hazardous (batteries, medicines, sanitary waste).

Composting converts kitchen and garden waste into manure; vermicomposting uses earthworms.

3Rs: reduce, reuse, recycle; avoid single-use plastic and carry a cloth bag.

Vector control: empty stagnant water weekly, cover storage, use nets, and keep surroundings clean.

Personal hygiene: daily bath, oral care twice a day, clean nails, hair and clothes.

Meal planning principles: adequacy, balance, variety, economy, satiety and consideration of family needs and practices.

Indian meal pattern: cereal staple, pulse, vegetable, milk or curd, and fat; fruits fill micronutrient gaps.

Dietary guidelines: whole grains and millets, plenty of vegetables and fruits, limited sugar, salt and fat, iodised salt, and adequate water.

Special diets: pregnancy (extra protein, iron, calcium, folate), lactation (energy and fluids), diabetes (limit refined sugar), hypertension (limit salt), obesity (limit energy-dense fried foods).

Cost control: buy seasonal and local foods, use whole pulses and cereals, avoid packaged snacks, plan a weekly menu and a shopping list.

Food exchange lists allow substitution within a group to keep nutrient value constant; exchange a cereal with a cereal, not with a pulse.

Hygiene in meal planning: clean utensils, safe water, covered storage and prompt serving.

A balanced tiffin includes a cereal staple, a protein item, a vegetable or fruit, and water; avoid excess oil, sugar and packaged snacks.

Menu planning for a family of four: include cereal, pulse, vegetable, milk product and fruit across the day, with one seasonal vegetable and one fruit for economy.

Family functions: reproduction, socialisation, economic support, emotional security, care of dependents and transmission of culture.

Family types: nuclear, joint and extended; by residence: patrilocal, matrilocal and neolocal.

Family life cycle stages: beginning, expanding, launching, contracting and ageing; needs and resources shift at each stage.

Needs: primary (food, clothing, shelter) and secondary (education, recreation, status); Maslow's order is physiological, safety, belonging, esteem, self-actualisation.

Resources: human (time, energy, knowledge, skills, attitudes) and non-human (money, goods, land, community facilities).

Communication has a sender, message, channel, receiver and feedback; barriers include assumptions, unclear words, emotions and poor listening.

Conflict resolution: stay calm, state the issue without blame, listen, look for options, agree and review.

Parenting styles: authoritarian, authoritative (firm with explanation and warmth), permissive and uninvolved.

Community resources: schools, health centres, Anganwadi, panchayat, libraries, cooperatives and self-help groups.

Management process: planning, organising, implementing and evaluating; it is cyclical and flexible.

Budget: a written plan of income and expenditure; steps are estimating income, listing fixed and flexible expenses, allocating for savings, and comparing actual with planned spending.

Time management: daily time plan, priority lists, peak-energy work at peak-energy hours, combining tasks and delegating.

Work simplification: labour-saving tools, arranged work centres, sitting for long tasks, and avoiding fatigue.

Decision-making steps: identify the problem, list alternatives and consequences, choose, act and evaluate.

Consumer rights: safety, information, choice, being heard, redressal and consumer education.

Consumer Protection Act, 2019: covers goods and services, e-commerce and misleading advertisements; three-tier redressal at district, state and national level.

Standard marks: ISI, FSSAI, Agmark, Hallmark, Ecomark.

Advertising techniques: glamour, repetition, celebrity endorsement, bandwagon, free gifts and fear appeal.

Functions of a house: shelter and protection, privacy, space for activities, storage, and a setting for health and social life.

Site selection: soil and drainage, safe water, sunlight and ventilation, access to school, market and health centre, and freedom from noise, dust and flooding.

House planning principles: orientation, cross-ventilation, zoning of activity areas, and provision for future needs.

Activity zones: living/social, sleeping/private, work/service (kitchen, washing) and circulation.

Kitchen work triangle links sink, cooking range and refrigerator; a short, unobstructed triangle reduces steps.

Elements of design: line, form, colour, texture and space; principles: balance, rhythm, proportion, emphasis and harmony.

Colour schemes: monochromatic, analogous and complementary; warm colours advance, cool colours recede, light colours make rooms look larger.

Space management: vertical storage, multipurpose furniture, foldable items and de-cluttering.

Ventilation and lighting: daylight and cross-ventilation reduce dependence on fans and lights; task lighting for reading, cooking and stitching.

Fibres are natural (cotton, silk, wool, jute) or man-made (rayon, polyester, nylon, acrylic); staple fibres are short, filament fibres long and continuous.

Cotton: absorbent, strong when wet, poor elasticity, shrinks; burns with a paper smell and grey ash.

Silk and wool are protein fibres; both burn with a burnt-hair smell; wool felts on washing and silk is weaker when wet.

Synthetics are strong, quick-drying, thermoplastic and non-absorbent; they melt on a hot iron.

Yarn is made by spinning; fabric by weaving (warp and weft), knitting (interlocking loops) or non-woven bonding.

Weave types: plain, twill and satin; the bias is at 45° and stretches most.

Basic hand stitches: running, back, hemming, blanket, chain and buttonhole; basic seams: plain, French and run-and-fell.

Body measurements: bust/chest, waist, hip, shoulder width, sleeve length, back length and garment length.

Clothing selection considers climate, occupation, age, figure, fashion, durability, comfort and budget.

Five food groups: cereals and millets; pulses and legumes; milk and meat products; fruits and vegetables; fats and sugars.

Energy values: carbohydrate 4 kcal/g, protein 4 kcal/g, fat 9 kcal/g; vitamins and minerals supply no energy.

Protein is made of amino acids; animal proteins are complete, most cereal proteins are limiting in lysine; cereal and pulse together improve protein quality.

Deficiency diseases: kwashiorkor and marasmus (protein-energy malnutrition), night blindness (vitamin A), rickets (vitamin D), anaemia (iron), goitre (iodine), scurvy (vitamin C), beriberi (thiamine), pellagra (niacin).

Fat-soluble vitamins A, D, E and K are stored in the body; water-soluble B-complex and C must be supplied daily.

WHO definition of health: a state of complete physical, mental and social well-being, not merely the absence of disease.

Energy needs rise with age until adulthood and are higher in pregnancy, lactation and heavy work.

Food safety: wash hands and produce, keep cooked food covered, avoid repeated reheating, and use clean water.

Adulteration tests: iodine for starch in milk, hydrochloric acid for metanil yellow in turmeric, and acid for chalk in flour.

Cooking methods: moist heat (boiling, steaming, stewing, pressure cooking) and dry heat (baking, roasting, grilling, frying).

Water-soluble vitamins B and C are lost by leaching into cooking water and by heat; use minimal water and short cooking time.

Do not add soda to vegetables or pulses; it destroys thiamine and vitamin C.

Vitamin C-rich foods are best cut just before cooking and cooked in an acid medium (lemon, tamarind).

Heat effects: protein coagulates (egg sets), starch gelatinises (rice softens), dry heat dextrinises starch (bread toasts), sugar caramelises.

Preservation principles: remove moisture, lower pH, add salt or sugar, apply heat and seal, and use cold storage.

Home preservation: sun drying, salting, pickling, jam, jelly, marmalade, squash, syrup and freezing.

Jam sets with pectin, acid and sugar; jelly is clear fruit-juice gel; marmalade contains citrus peel.

Rancidity is the spoilage of fats giving an off smell; store oils in a cool dark place in opaque containers.

Home Science is the applied science of home and family living, drawing on biology, chemistry, physics, economics, psychology and sociology.

Its five classical areas are food and nutrition, textiles and clothing, home management, child development, and family/community living; housing, hygiene and consumer education are commonly added.

Scope runs from the individual (health, diet, clothing) to the family (budget, relationships) to the community (sanitation, nutrition education, consumer protection).

Home Science is interdisciplinary: one problem such as malnutrition is studied through food science, economics and child care together.

Career paths: dietetics and nutrition, food technology and quality control, textile and fashion design, interior design, preschool/child care, community development, extension education and consumer journalism.

Higher-study routes: B.Sc. Home Science, B.Sc. Food Technology, B.A. Fashion Design, B.Ed. for teaching, and diplomas in dietetics, preschool teaching and interior decoration.

Public-sector roles: Anganwadi worker/supervisor, nutrition educator, extension officer, school teacher and hospital dietitian assistant.

Entrepreneurship options: tiffin service, bakery, tailoring and boutique, day-care centre, interior consultancy and home-based food preservation units.

Home Science students demonstrate practical skills (cooking, stitching, budgeting, child observation) alongside theory; practical marks are part of assessment.

Read the whole paper first, mark questions you know, and allocate time by marks; a 5-mark question needs more points than a 1-mark question.

Definition questions need a precise one- or two-line definition plus one example.

Difference questions need a two-column table with paired points on the same basis.

Reason questions need a cause-and-effect answer: soda destroys vitamin C and thiamine, so nutrient value falls.

Diagram questions need a labelled, neat diagram and a one-line caption; write labels horizontally.

Common mark-losing errors: unlabelled diagrams, answers without examples, mixing up deficiency diseases, and ignoring the marks allotted.

Revise definitions, unit conversions, food-group classification, first-aid steps and fabric-care symbols for the viva.

Make one-page summaries per domain, use mnemonics for lists, and practise past-paper question types.

In practical exams, keep the work area clean, follow safety, present neatly, and explain each step you performed.

A project report includes title, introduction/need, objectives, method or procedure, observations or results, discussion, conclusion and references.

Practical skills assessed include cooking and plating, stitching a simple garment or article, stain removal, first aid, child observation, budgeting and making a consumer complaint.

For a food practical, record the recipe with ingredients in standard measures, method, time, cost per serving and nutrient contribution.

For a textile practical, record body measurements, fabric chosen and why, pattern, stitches used and finishing details.

A child-study observation records age, setting, behaviour observed (motor, language, social) and interpretation against developmental norms, without naming the child.

A consumer-education project can compare unit prices of two brands, check labels for FSSAI/ISI marks, or draft a complaint letter with a cash memo as proof.

Market surveys should use a simple, short questionnaire, a clear sample and tally results; avoid leading questions.

First aid basics: cool burns with running water, press a clean cloth on cuts to stop bleeding, and refer serious cases to a health facility.

Safety in the practical room: tie hair back, use dry hands for electrical appliances, turn pot handles inward, and know where the first-aid box is kept.

Extension education carries useful knowledge from the school or college to families; its steps are identifying needs, planning, executing and evaluating change in behaviour.

Teaching aids: charts, flash cards, flip books, posters, demonstrations, role play, puppets and street plays; choose the aid for the audience's literacy level.

A demonstration teaches by showing and telling: introduce the topic, show the method step by step, let learners practise, and summarise key points.

Nutrition education messages should be simple, in local words, and use local foods such as millets, seasonal vegetables and curd.

Anganwadi and ICDS services include supplementary nutrition, pre-school education, immunisation, health check-ups and nutrition education.

Self-help groups enable small savings, micro-credit and collective enterprise; Home Science skills such as food processing and tailoring can become group livelihood.

Home accidents are prevented by non-slip floors, safe storage of kerosene, medicines and pesticides, and keeping sharp and hot items out of children's reach.

Waste-to-wealth projects: cloth bags from old fabric, paper bags, compost from kitchen waste and reusable household items.

Documentation of community work should record date, place, target group, activity, participation and outcome.

Gelatinisation: starch granules absorb water and swell on heating, thickening the liquid; cooling sets it into a gel.

Dextrinisation: dry heat converts starch to dextrins, browning toast and roasted grains.

Caramelisation: sugar melts and browns on heating; overheating gives a bitter taste.

Coagulation: proteins set on heating; adding acid or salt speeds coagulation of milk protein.

Emulsification: an emulsifier such as egg yolk lecithin holds oil and water together, as in mayonnaise.

Leavening agents: yeast (biological), baking powder and soda (chemical), and air or steam (physical) make dough rise.

Acids firm up pectin in vegetables and slow softening; alkalis make vegetables mushy and destroy vitamins.

Enzymatic browning darkens cut apples and brinjal; dipping in salt water, lemon juice or blanching slows it.

Smoke point: oil heated beyond it breaks down and gives off-flavour; do not reuse oil repeatedly.

Washing steps: sorting, mending, stain removal, short soaking, washing, rinsing, starching (optional), drying and ironing.

Soaps are alkaline sodium salts of fatty acids; detergents work in hard water and are available for delicate fabrics.

Starching gives crispness and body to cotton; use thin starch for light fabrics and thick for collars and cuffs.

Ironing temperatures: cotton and linen high, wool medium with a damp cloth, silk low, synthetics low.

Shrinkage is highest in cotton and rayon; pre-shrink fabric by washing before cutting or buy extra length.

Darning repairs holes by weaving threads across the hole; patching is used for larger holes, matching grain and colour.

Buttons, hooks and press studs are fasteners; buttonholes should be worked with matching thread and reinforced at the ends.

Storage: clean and dry clothes, use neem leaves against insects, avoid naphthalene touching woollens, and air woollens before storing.

Readymade garment fit: check shoulder seam position, ease at bust and hip, sleeve length and hem; alterations are limited by seam allowance.

Weaning foods should be soft, semi-solid, single-ingredient at first, and introduced one at a time to detect allergy; start around 6 months.

Childhood illness signs: diarrhoea (dehydration - use ORS), fever, cough and cold, ear discharge and skin rash; danger signs need immediate referral.

Discipline should be consistent, explain the reason, and use withdrawal of privileges rather than physical punishment.

Language development: cooing, babbling, first words around 1 year, two-word sentences around 2 years, rapid vocabulary growth in early childhood.

Toilet training is possible when the child shows readiness, usually between 2 and 3 years.

Play materials should be safe (no small parts, non-toxic paint), simple and suited to the child's stage.

Teething usually begins around 6 months; clean gums and first teeth with a soft cloth or brush.

First aid for a child: keep calm, assess breathing, control bleeding, and never give medicines without advice.

Keep poison control and doctor numbers handy; store medicines and chemicals out of reach.

A good house plan provides light and ventilation (window area about one-fifth of floor area is a common guide), privacy, storage and safe circulation.

Kitchen types: one-wall, two-wall (corridor), L-shaped, U-shaped and island; the U-shape suits large kitchens, the one-wall suits small flats.

Ventilation may be natural (windows, ventilators) or mechanical (exhaust fan, chimney).

Floor coverings: durries and carpets add warmth and absorb sound; washable mats suit kitchens and bathrooms.

Curtain types: pleated, café, roman and roller; lined curtains give privacy and insulation, sheer curtains admit light.

Lighting types: general (ceiling), task (study lamp, kitchen counter) and accent (decorative); use energy-efficient lamps.

Colour scheme choice depends on room size, light, function and user preference; a small dark room benefits from light, cool colours.

Furniture arrangement should keep doorways and passages clear and group seating for conversation.

Home safety: non-slip bathroom flooring, grab bars for the elderly, covered electrical sockets for children and clear stairways.

Lifestyle diseases - obesity, type 2 diabetes, hypertension and heart disease - are linked to excess energy intake, fried and sugary foods, and physical inactivity.

BMI = weight in kg ÷ (height in metres)²; under 18.5 is underweight, 18.5–24.9 normal, 25–29.9 overweight, 30 and above obese (WHO adult cut-offs).

Obesity management: reduce energy-dense foods, increase fibre, exercise regularly, and avoid crash diets.

Diabetes diet: regular meal timing, complex carbohydrates, high fibre, limited refined sugar, and monitoring as advised.

Hypertension: limit salt, pickles and papads, avoid smoking and excess alcohol, maintain weight and exercise.

Anaemia prevention: iron-rich foods (green leafy vegetables, jaggery, liver, pulses), vitamin C to aid iron absorption, and avoiding tea with meals.

Smoking, tobacco chewing, alcohol and substance use are major preventable health risks; refusal skills are part of health education.

Physical activity: at least 60 minutes of moderate activity daily for adolescents; about 150 minutes a week for adults.

Mental health: adequate sleep, supportive relationships, and seeking help for persistent sadness or anxiety are part of overall health.

Safe water supply at home: protected source, storage in a covered container with a tap, regular cleaning, and treatment before drinking.

Excreta-related diseases (cholera, typhoid, dysentery, worm infestation) are prevented by toilets, handwashing with soap and safe water.

Mosquito control: empty stagnant water from coolers, pots and tyres; cover storage; use nets and screens.

Indoor air pollution from chulhas and open burning harms the eyes and lungs; a smokeless chulha, LPG or chimney reduces smoke.

Waste management hierarchy: prevent, reduce, reuse, recycle, recover (compost or energy), and dispose as the last option.

Plastic waste: avoid single-use plastic, carry cloth bags, segregate and recycle; burning plastic releases toxic fumes.

E-waste (old phones, batteries, chargers) should go to authorised collection points, not kitchen waste.

Noise pollution harms hearing and concentration; keep loudspeakers and TV volume low and observe silence zones.

Green practices at home: grow plants, harvest rainwater, use natural light, and repair rather than discard.

Portfolio building: collect recipes, stitched samples, charts, survey reports and photographs; a portfolio demonstrates skill at interviews and admissions.

Self-employment costing: add material cost, labour, overheads and a margin to fix a price; keep a simple record of sales and expenses.

Hygiene and licensing for a home food business: clean premises, safe water, trained handling, correct labelling and FSSAI registration.

Customer service basics: clear communication, keeping promises about quality and delivery, and handling complaints politely.

Communication skills for extension work: speak in the local language, use examples, invite questions, and check understanding.

Interview readiness: know the job's requirements, prepare examples of practical work, and keep certificates and portfolio ready.

Digital skills: use a smartphone for price comparison, online banking safely, and sharing information; verify before forwarding messages.

Teamwork in group projects: divide work by skill, set deadlines, and record individual contributions.

Ethics in applied work: honesty in reporting, respect for privacy in child and family studies, and no exaggeration of product claims.

Read the whole paper first, mark questions you know, and allocate time by marks.

Definition questions need a precise one- or two-line definition plus one example.

Difference questions need a two-column table with paired points on the same basis.

Reason questions need a cause-and-effect answer with the scientific reason.

Diagram questions need a labelled, neat diagram and a one-line caption; write labels horizontally.

Revise definitions, unit conversions, food-group classification, first-aid steps and fabric-care symbols for the viva.

Make one-page summaries per domain, use mnemonics for lists, and practise past-paper question types.

Common mark-losing errors: unlabelled diagrams, answers without examples, mixing up deficiency diseases, and ignoring the marks allotted.

In practical exams, keep the work area clean, follow safety, present neatly, and explain each step you performed.

Cereals and millets (wheat, rice, maize, bajra, ragi) are the main energy source, supplying carbohydrate, some protein, B vitamins and fibre.

Pulses and legumes (dal, gram, rajma, soyabean) are the main plant protein source and also supply iron, calcium and B vitamins.

Milk and milk products supply good-quality protein, calcium, riboflavin and vitamin A (in whole milk); curd is easier to digest.

Meat, fish, eggs and poultry supply complete protein, iron, zinc and B vitamins; egg white is a reference protein.

Green leafy vegetables supply iron, calcium, carotene, vitamin C and fibre; darker leaves are richer.

Yellow and orange fruits and vegetables (carrot, papaya, mango, pumpkin) are rich in carotene; citrus fruits (orange, amla, guava) are rich in vitamin C.

Fats and oils (ghee, mustard oil, groundnut oil) supply essential fatty acids and help absorb fat-soluble vitamins.

Sugar and jaggery supply energy only; jaggery retains some minerals but is still a concentrated sugar and should be limited.

Iodised salt supplies iodine; use it in moderation and add near the end of cooking to retain iodine.

Drying is the oldest method; vegetables and fruits are blanched, dried in sun or a dehydrator, and stored in airtight containers.

Pickling uses salt, oil, acid (vinegar or lemon) and spices; the acid and salt inhibit microorganisms; use dry spoons and keep the surface covered with oil.

Jam, jelly and marmalade need pectin, acid and sugar; fruits low in pectin need added pectin, while citrus and apple are rich in it.

Squash and syrup are preserved fruit juices with sugar and permitted preservative; store in sterilised bottles.

Canning requires sterilising jars, filling hot, exhausting air, sealing and heat processing; a failed seal or bulging lid means spoilage - discard.

Freezing slows microbial growth but does not kill microorganisms; blanch vegetables first, pack airtight and thaw in the refrigerator.

Refrigerator storage: cooked food above raw meat, covered containers, do not overload, and keep the temperature between 1 and 4 °C.

Dry storage: cool, dark, ventilated place, airtight containers, rotation of older stock to the front, and protection from insects and rodents.

Signs of spoilage: off smell, slime, mould, gas, changed colour or texture; never taste to check - discard.

Communication has a sender, message, channel, receiver and feedback; barriers include assumptions, unclear words, emotions and poor listening.

Active listening means giving attention, not interrupting, asking questions and reflecting back what was heard.

Conflict resolution steps: stay calm, state the issue without blame, listen to the other side, look for options, agree and review.

Parenting styles: authoritarian (strict, little explanation), authoritative (firm with explanation and warmth - usually most effective), permissive (few limits), uninvolved.

Sibling relationships teach sharing, negotiation and fairness; parents should avoid comparisons and give each child individual attention.

Care of the elderly: respect, inclusion in decisions, help with health needs, and attention to loneliness.

Adolescent–parent communication improves with open questions, respect for privacy, consistent rules and shared meals.

Family crises (illness, financial loss, death) need honest communication suited to the child's age, reassurance and routine.

Gender-fair practices at home: shared chores, equal schooling, and equal say in decisions benefit family well-being.

Metric units: 1 kg = 1000 g, 1 litre = 1000 ml, 1 metre = 100 cm; use the unit asked for and show the working.

Standard measures: 1 cup ≈ 200 ml, 1 tablespoon ≈ 15 ml, 1 teaspoon ≈ 5 ml; level measures give repeatable results.

Percentage: part ÷ whole × 100; used for nutrient contribution, budget share and wastage.

Cost per serving = total ingredient cost ÷ number of servings; compare with the market price of a similar ready product.

Budget balance: total income = total expenditure + savings; if expenditure exceeds income, cut flexible expenses first.

BMI = weight (kg) ÷ height (m)²; convert height in cm to metres before calculating.

Energy contribution: multiply grams of nutrient by its kilocalorie value (carbohydrate 4, protein 4, fat 9).

Fabric requirement ≈ length of garment + sleeve length (if cut separately) + seam allowance + shrinkage allowance.

Time planning: list tasks, estimate time, set priorities, and add a buffer; compare planned with actual time to improve next time.

Primary Health Centre and sub-centre provide basic curative care, immunisation, maternal and child health services and referral.

Anganwadi centre provides supplementary nutrition, pre-school education, health check-ups and nutrition education for pregnant women and children under six.

ASHA worker links the community with the health system - antenatal care, immunisation, ORS and referral advice.

Panchayat and municipal bodies manage water supply, sanitation, drainage, street lighting and waste collection.

Schools, libraries and youth clubs provide learning, recreation and awareness activities; Home Science students can conduct extension activities through them.

Self-help groups and cooperatives offer savings, credit and collective marketing for home-based enterprises.

Consumer helpline and District Consumer Commission provide redressal; keep the bill and proof of complaint.

Police, fire service, ambulance and hospital contacts should be displayed at home and in school.

NGOs and voluntary organisations support nutrition, sanitation and child welfare projects; students can volunteer or survey with them.

Balanced diet: a diet that supplies all nutrients in the required amounts and proportions for a person's age, sex and activity, with some extra for fibre and water.

Food group: a set of foods with similar nutrient composition, grouped so that a balanced diet can be planned and exchanged within the group.

Adulteration: the addition of a cheaper, inferior or harmful substance to food to increase quantity or improve appearance; detected by simple chemical tests.

Preservation: treating food to stop or slow spoilage so it can be stored and used later, by removing moisture, heat, cold, acid, salt, sugar or air.

Development: progressive change in the child's capacity and behaviour over time; growth is increase in size or weight, a part of development.

Resource: anything used to achieve a goal; human resources are within the person, non-human resources are material and environmental.

Budget: a plan for spending money over a period, matching income to needs, wants and savings.

Hygiene: practices that keep the body, food, water and surroundings free of disease-causing organisms.

Sanitation: safe management of human waste, waste water and solid waste to protect health and the environment.

Practical file cover should carry name, class, roll number, subject and session; each practical should have date, aim, materials, procedure, observation and conclusion.

Recipe format: ingredients in standard measures, method in numbered steps, cooking time, number of servings, cost per serving and a nutrient note.

Stitching sample format: name of article, fabric, measurements, pattern used, stitches and seams, finishing, and a small sketch or sample.

Survey format: objective, sample size and method, questionnaire or checklist, table of results, interpretation, conclusion and suggestions.

Child observation format: age, setting, time, behaviour noted under motor, language, social and emotional heads, interpretation and caution about privacy.

First-aid practical format: situation, steps taken, materials used, do's and don'ts, and when to refer to a doctor.

Marks are commonly given for accuracy, neatness, hygiene, safety, time management, use of local and economical materials, and viva answers.

Common deductions: missing conclusion, unlabelled diagram, unmeasured ingredients, untidy work area, unsafe handling of hot or sharp items.

Keep a rough notebook for observations in the practical room and write the fair record neatly afterwards.

FSSAI is the food safety regulator; packaged food must carry its licence number, and consumers can complain about unsafe or mislabelled food.

Food fortification adds vitamins and minerals to staples; fortified rice and wheat flour, iodised salt and double-fortified salt are common examples.

Poshan Abhiyaan aims to reduce malnutrition, anaemia and low birth weight through convergence of nutrition services and behaviour change.

Anaemia Mukt Bharat targets anaemia through iron-folic acid supplementation, deworming, fortified foods and testing.

ORS and zinc are promoted for childhood diarrhoea; continued feeding and fluids prevent malnutrition during illness.

Vitamin A supplementation and deworming are part of child health services delivered through schools and Anganwadi centres.

Mid-day meal guidelines require a hot cooked meal, hygiene in cooking and serving, and a varied menu with local foods.

Food safety at home: separate raw and cooked food, cook thoroughly, keep food at safe temperatures, use safe water and raw materials.

Consumers can report food adulteration to the local food safety office with a sample and receipt.

Fibre identification tests: burning test (smell and ash), feel test and solubility test; cotton smells of paper, wool and silk of burnt hair, synthetics melt into a bead.

Yarn count and twist affect fabric strength and texture; higher twist gives a smoother, stronger yarn.

Warp threads run lengthwise, parallel to the selvedge; weft threads run across; the bias is at 45° and stretches most.

Fabric finishes: mercerisation (cotton, adds lustre and strength), calendering (smooth surface), sanforisation (controls shrinkage), water-repellent and flame-retardant finishes.

Dyeing colours the whole fabric, printing applies colour in patterns; fastness to washing and light determines quality.

Basic pattern symbols: grain line, fold line, notch, dart, buttonhole and seam allowance line; cutting on the fold gives a symmetrical piece.

Seam allowance is usually 1–1.5 cm; clip curves and trim corners before turning to get a smooth shape.

Care symbols: washtub (washing), triangle (bleaching), square with circle (drying), iron (ironing temperature), circle (dry cleaning).

Wardrobe planning: choose clothes that mix and match, suit the climate and occasion, and fit the budget; mend promptly to extend life.

Work simplification reduces fatigue by better arrangement: store frequently used items within easy reach, group similar tasks, and use both hands.

Kitchen work triangle: the three sides should total roughly 4–8 metres for efficient movement; obstacles inside the triangle increase steps.

Standard counter height is about 85 cm, with the work surface slightly lower for tall users and higher for short users to avoid stooping.

Storage principles: store at the point of first use, keep heavy items low, keep frequently used items at eye-to-hand level, and label containers.

Zoning at home: separate noisy (kitchen, living) from quiet (study, bedroom) areas and keep the toilet away from the kitchen.

Space-saving furniture: bunk beds, folding tables, wall-mounted shelves, and storage under the bed or stairs.

Good lighting reduces eye strain; place study lamps on the opposite side of the writing hand to avoid shadow.

Ventilation and cross-ventilation reduce humidity, smoke and odours; a kitchen must have an exhaust or window.

Home maintenance: check taps for leaks, whitewash regularly, repair cracks, and keep drains clear to prevent mosquitoes and dampness.

Six consumer rights: safety, information, choice, being heard, redressal and consumer education; later additions include the right to a healthy environment.

Consumer Protection Act, 2019 covers goods and services, e-commerce and misleading advertisements; it provides for product liability and unfair trade practice penalties.

Three-tier redressal: District Commission (lower value claims), State Commission (appeals and higher value), and National Commission (highest value and appeals).

A complaint should state the facts, the loss or injury, the relief sought, and attach the bill, warranty, photographs or correspondence.

A cash memo, warranty card, guarantee and label are the consumer's evidence; keep them until the product is used up.

Misleading advertisement claims can be complained about to the regulator; exaggerated health claims about food are a common example.

Jago Grahak Jago is a consumer awareness initiative; the national consumer helpline assists with complaints.

Standardisation marks: ISI for industrial goods, FSSAI for food, Agmark for agricultural produce, Hallmark for gold, and Ecomark for environment-friendly products.

Wise buying steps: identify the need, gather information, compare brands and unit prices, check the label and mark, buy, and keep the proof.

Physical growth: birth weight doubles by about 5 months and triples by 1 year; height increases by about 50 per cent in the first year.

Social smile appears around 6–8 weeks; stranger anxiety around 7–9 months; parallel play in toddlers; cooperative play in early childhood.

Language: crying and cooing in the first months, babbling at 6–9 months, first meaningful word around 1 year, two-word phrases around 2 years.

Cognitive development in early childhood is marked by symbolic play, curiosity, short attention span and egocentric thinking.

Emotional development: attachment to the mother or caregiver in infancy, temper tantrums in toddlers, and growing self-control in later childhood.

Nutrition for the young child: breast milk up to 6 months, complementary foods from 6 months, family food by 1–2 years, small frequent meals and no force feeding.

Immunisation and growth monitoring at the Anganwadi centre protect the child; keep the immunisation card safe.

Care of the child with diarrhoea: give ORS and zinc, continue feeding and breastfeeding, and seek help for blood in stool or persistent vomiting.

Safety at home for the child: gate the stairs, cover sockets, keep medicines and sharp objects out of reach, and supervise water play.

Segregate waste at home into wet (biodegradable), dry (recyclable) and hazardous (batteries, medicines, sanitary waste).

Composting needs a mix of green (kitchen waste) and brown (dry leaves, paper), moisture, air and time; turning the pile speeds decomposition.

Vermicomposting uses earthworms to convert organic waste into nutrient-rich manure; keep the bed moist and shaded.

Rainwater harvesting collects roof water into a tank or recharge pit; it reduces dependence on groundwater and prevents flooding.

Water conservation at home: fix leaks, use a bucket instead of a running tap, reuse vegetable-washing water for plants, and cover stored water.

Energy conservation: switch off unused lights and fans, use LED bulbs, use solar water heaters, and keep refrigerators away from heat sources.

Tree planting and care: choose local species, water regularly, protect saplings, and avoid cutting trees; trees reduce dust, heat and noise.

Avoid open burning of waste and crackers; it releases harmful gases and worsens air pollution.

Community action: cleanliness drives, awareness rallies, school eco-clubs and plastic-free campaigns involve families in environmental improvement.

Menu planning for a family of four: include cereal, pulse, vegetable, milk product and fruit across the day; keep one seasonal vegetable and one fruit for economy.

Packing a balanced tiffin: a cereal staple, a protein item, a vegetable or fruit, and water; avoid too much oil, sugar or packaged snacks.

Safe food handling: wash hands and utensils, keep raw and cooked food separate, cook thoroughly, store at safe temperature, and use safe water.

Kitchen first aid: cool a burn with running water, cover a cut with a clean cloth, and never apply toothpaste or oil to a burn.

Stain removal at home: cold water for blood and egg, detergent for grease, lemon and salt for rust or ink, and sunlight for mildew on cotton.

Mending and repair: stitch a tear promptly, replace missing buttons, darn holes in socks and elbows, and repair hems to extend garment life.

Budget for a small family: list fixed expenses first, then flexible; set aside savings and an emergency fund before spending on wants.

Home cleaning routine: sweep and mop daily in the kitchen, clean the toilet with disinfectant, wash dustbins, and air bedding in sunlight.

Emergency kit: torch, first-aid box, ORS, candles, matches, drinking water, important documents and a list of emergency numbers.

WHO definition of health: a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.

Energy values: carbohydrate 4 kcal/g, protein 4 kcal/g, fat 9 kcal/g; alcohol supplies about 7 kcal/g but is not a nutrient.

Adult BMI categories: underweight below 18.5, normal 18.5–24.9, overweight 25–29.9, obese 30 and above (WHO adult cut-offs).

Colostrum is the first thick yellowish milk, rich in antibodies (immunoglobulin A) and should be given to the newborn within the first hour.

Exclusive breastfeeding is recommended for the first 6 months; complementary feeding starts at 6 months and breastfeeding continues up to 2 years.

ORS is a mixture of salt and sugar in water that replaces water and electrolytes lost in diarrhoea; zinc is given along with it.

Standard marks: ISI (BIS) for industrial goods, FSSAI for food, Agmark for agricultural produce, Hallmark for gold.

Consumer Protection Act, 2019 replaced the 1986 Act and covers e-commerce and product liability.

3Rs of waste management: reduce, reuse, recycle; the wider hierarchy adds refuse and rot (compost) before recycle.

Knife cuts and their use: slicing for even cooking, dicing for salads and stuffings, chopping for gravies, and julienne for garnishes.

Methods of cooking with examples: boiling (rice), steaming (idli), pressure cooking (dal), shallow frying (paratha), deep frying (pakora), baking (cake), roasting (chana).

Advantages of pressure cooking: saves fuel and time, retains more water-soluble vitamins, and cooks pulses and tough meats quickly.

Sprouting increases vitamin C, improves digestibility and reduces anti-nutrients in pulses; germinate in a moist, clean cloth and use fresh.

Fermentation (curd, idli, dhokla) improves digestibility, adds B vitamins and beneficial bacteria; use a clean starter and warm conditions.

Basic hand stitches: running (gathering, tucking), back (strong seams), hemming (neat edges), blanket (edges of blankets), chain (decoration), buttonhole.

Seam types: plain (simple, needs finishing), French (neat, for light fabrics), run-and-fell (strong, for children's clothes and jeans).

Home cleaning agents: soap and detergent for grease, acid (lemon, vinegar) for hard water stains, bleach for disinfection (use with care and never mix with acid).

Fire safety at home: keep a bucket of sand or a fire extinguisher in the kitchen, never pour water on an oil fire, and turn off the gas after cooking.

Nutrition education aims at behaviour change, not just knowledge; use local foods, demonstrations and repeated messages.

Growth charts plot weight or height for age; a child below the line or with a falling curve needs assessment and referral.

Nutritional assessment methods: dietary survey (24-hour recall, food frequency), anthropometry (weight, height, MUAC), clinical examination and biochemical tests.

Mid-upper arm circumference (MUAC) is a quick field measure of wasting in children; a coloured tape classifies the child.

Common nutritional problems in India: protein-energy malnutrition, iron-deficiency anaemia, vitamin A deficiency, iodine deficiency disorders and obesity in urban areas.

Dietary guidelines recommend plenty of vegetables and fruits, whole grains and millets, limited fat, sugar and salt, and adequate water.

Food-based approaches to malnutrition: kitchen gardens, poultry and dairy, inclusion of millets and pulses, and improved cooking practices.

Health education on hygiene: handwashing with soap at five critical times - after toilet, after cleaning a child, before food preparation, before eating and before feeding a child.

Community participation makes programmes work: involve mothers' groups, school children and local leaders in planning and monitoring.

Goal setting: distinguish short-term (a school bag), medium-term (a cycle) and long-term (a house) goals; plan savings accordingly.

Money management steps: record income, list expenses, prepare a budget, keep accounts, review monthly and adjust.

Time savers at home: plan the day, combine tasks (soak dal while preparing vegetables), use a pressure cooker and mixie, and share work among family members.

Energy savers: sit for long tasks, keep frequently used items at waist height, use a trolley, and avoid unnecessary trips.

Decision-making in purchase: compare brands, check unit price, read the label, consider durability and after-sales service, and avoid impulse buying.

Consumer aids: cash memo, warranty card, guarantee, standardisation marks and the consumer helpline.

Resource substitution: use time for money (cook at home instead of buying), or money for time (buy a labour-saving appliance) depending on which is scarcer.

Family budget shares: food, housing, education, health, clothing, transport and savings; needs come before wants, and savings are a planned item.

Records help: keep bills, bank passbook, insurance papers and a simple account book; review insurance and savings annually.

Orientation: in hot climates, the longer walls face north-south and the shorter walls east-west to reduce heat gain; verandahs and sunshades protect windows.

Ventilation rate depends on window area, position and openings on opposite sides; a ventilator near the ceiling removes hot air.

Kitchen planning: place the sink near the preparation area, the cooking range near the window or chimney, and storage near the work centres.

Bathroom planning: non-slip flooring, proper drainage slope, ventilation, and a water source away from the kitchen.

Bedroom planning: quiet location, cross-ventilation, storage for clothes, and a bed away from direct draughts and bright light.

Living room furnishing: group seating for conversation, leave circulation space, and use a focal point such as a window or artwork.

Curtain selection depends on privacy, light control, room size and washability; lined curtains give privacy and insulation.

Floor coverings: small rugs define areas in a large room; washable mats suit kitchens and bathrooms.

Home safety for children and the elderly: stair rails, non-slip mats, adequate lighting, and no loose wires or low-hanging cords.

Personal hygiene includes bathing daily, brushing teeth twice a day, washing hair regularly, trimming nails, and wearing clean clothes.

Handwashing with soap removes germs; the five critical times are after toilet, after cleaning a child, before cooking, before eating and before feeding a child.

Menstrual hygiene: use clean absorbent, change every 4–6 hours, wash with clean water, and dispose of used pads wrapped in paper in a covered bin.

Oral hygiene: brush twice daily with fluoride toothpaste, rinse after sweets, and visit a dentist for persistent pain or bleeding gums.

Foot care: wash and dry feet daily, wear clean cotton socks, cut nails straight across, and wear well-fitting footwear to prevent infection.

Safe water: boil, filter or chlorinate; store in a covered container with a tap and clean it regularly.

Food hygiene: wash hands and produce, cook thoroughly, keep cooked food covered, and avoid eating from unhygienic street vendors.

Cough and sneeze etiquette: cover mouth and nose with a handkerchief or elbow, and wash hands afterwards.

Sleep and rest: adolescents need about 8–9 hours of sleep; regular sleep improves concentration and health.

Washtub symbol with a number gives the maximum washing temperature; a hand in the tub means hand wash only; a cross means do not wash.

Triangle symbol: empty means any bleach allowed, crossed means no bleach, and diagonal lines mean only oxygen bleach.

Square symbol: a circle inside means tumble dry; dots indicate heat level; a line means line dry; a crossed square means do not dry.

Iron symbol: dots indicate temperature - one dot low (synthetics), two dots medium (wool, silk), three dots high (cotton, linen).

Circle symbol: dry clean only; a letter inside indicates the solvent; a crossed circle means do not dry clean.

Washing sequence: sort by colour and fabric, mend first, treat stains, soak briefly, wash, rinse well, dry in shade for colours, iron and fold.

Soap vs detergent: soap is alkaline and forms scum in hard water; detergent works in hard water and rinses easily.

Stain removal: cold water for blood and egg, absorbent powder for grease, lemon and salt for rust, and alcohol for ink; test on a hidden part.

Storage: clean and dry clothes, use neem leaves against insects, air woollens, and avoid naphthalene touching the fabric directly.

Play is essential for physical, cognitive, language, social and emotional development; it is the child's natural way of learning.

Types of play by age: solitary (infants), parallel (toddlers), associative and cooperative (preschool and older children).

Play materials should be safe, non-toxic, age-appropriate, simple and varied; homemade toys from safe waste material encourage creativity.

Outdoor play develops large muscles, coordination and social skills; indoor play develops fine muscles, imagination and language.

Storytelling and rhymes build vocabulary, listening and imagination; ask simple questions afterwards.

Free play allows the child to choose and explore; guided play adds adult support without taking over.

Television and mobile screens should be limited; too much screen time reduces active play and interaction.

Play and disability: adapt toys and games so children with different abilities can join; inclusive play builds empathy.

Adults should supervise, provide safe space and materials, and allow the child to solve problems rather than doing it for them.

Why should vegetables not be overcooked? Heat and water destroy vitamin C and B vitamins; minimal water and short cooking retain them.

Why is dal-rice a good combination? Cereal protein is low in lysine, pulse protein is low in methionine; together they give a better amino acid balance.

Why is vitamin C taken with iron-rich foods? Vitamin C converts iron to a more absorbable form and improves absorption from plant foods.

Why should tea not be taken with meals? Tannins in tea bind iron and reduce its absorption; take tea between meals.

Why is iodised salt added at the end of cooking? Iodine is lost on prolonged heating; add salt near the end and store in a closed container.

Why is colostrum important? It is rich in antibodies, proteins and vitamin A and protects the newborn from infection.

Why is ORS given in diarrhoea? It replaces water and electrolytes lost, preventing dehydration; continue feeding too.

Why is a balanced diet important for adolescents? Rapid growth and activity increase needs for energy, protein, iron and calcium; deficiencies affect growth and learning.

Why is fibre important? It prevents constipation, helps control blood sugar and cholesterol, and adds bulk to the diet.

Define and give one example for: balanced diet, food group, exchange list, adulteration, preservation, resource, budget, development, hygiene, sanitation.

Distinguish: growth vs development; jam vs jelly; staple vs protective food; fixed vs flexible expense; warp vs weft; boiling vs steaming; soap vs detergent.

Know the food groups and one rich source of each major nutrient: protein (pulse, milk, egg), iron (green leafy vegetables, jaggery), calcium (milk, ragi), vitamin C (amla, guava), vitamin A (carrot, papaya).
