OSAT Family and Consumer Sciences (OK109) key terms

Specific skills or behaviors most children can do within an expected age range, such as walking around twelve months. Teachers and caregivers use them to notice typical progress and flag possible delays needing further evaluation.

A lifespan theory proposing eight stages, each centered on a conflict such as trust versus mistrust in infancy or identity versus role confusion in adolescence. Resolving each conflict favorably is said to shape later personality and relationships.

The period roughly from ages seven to eleven when children reason logically about tangible objects and events, master conservation of number and liquid, and can classify and order items, but still struggle with abstract hypothetical reasoning.

A style combining high warmth and responsiveness with clear, explained expectations and consistent limits. Children raised this way tend to show better self-regulation and social competence than those raised under permissive, authoritarian, or neglectful approaches.

The view that a family is an interdependent unit whose members affect one another, so a change in one person or relationship ripples through the whole. It attends to roles, boundaries, communication patterns, and feedback loops.

A framework describing predictable transitions families pass through, such as launching young adults, joining through marriage, raising children, and later-life adjustments. Each stage brings new tasks and stressors that shape household needs and resources.

Adults simultaneously responsible for raising or supporting their own children and caring for aging parents. The double caregiving load affects finances, time, stress, and housing decisions, making it a common case in family resource management.

The physical, emotional, and financial strain experienced by someone providing ongoing care to a dependent person. Respite, support groups, and clear role sharing are typical interventions studied in family and community services.

An individualized education program: a legally required written plan for a student with a disability that sets measurable goals, specifies services and accommodations, and is reviewed at least annually with family participation.

Temporary support an adult or peer provides so a learner can complete a task just beyond independent ability, with the help gradually withdrawn as competence grows. It is a core application of Vygotsky's zone of proximal development.

The value of the next best alternative given up when a choice is made. Spending money on one item means forgoing other uses of those funds, so it underlies budgeting, saving, and comparative shopping decisions.

Interest calculated on both the original principal and previously accumulated interest, so balances grow faster over time. The same mechanism makes carrying credit card debt expensive while rewarding early, consistent saving.

Annual percentage rate: the yearly cost of borrowing expressed as a percentage, including certain fees, so consumers can compare loans and credit cards on a common basis. It differs from the simple periodic interest rate.

A record compiled by credit bureaus showing accounts, payment history, balances, and inquiries. Lenders use it, often with a credit score, to judge repayment risk; consumers may check it for errors and identity theft.

Fraud in which someone uses another person's personal information, such as a Social Security number, to open accounts or make purchases. Prevention includes strong passwords, monitoring statements, and freezing credit when needed.

A scam that impersonates a trusted organization through email, text, or calls to trick people into revealing passwords or account numbers. Recognizing urgent demands and verifying senders independently are key defenses.

Loan practices with unfair or abusive terms, such as excessive fees, hidden costs, or repayment structures designed to trap borrowers in repeated refinancing. Consumer education and disclosure rules aim to reduce it.

A plan that compares expected income with planned spending and saving over a period. A workable budget distinguishes fixed from variable expenses and sets aside money for emergencies and goals.

Money set aside in accessible savings to cover unexpected expenses such as car repairs or medical bills. Financial educators often recommend three to six months of essential living costs to avoid high-interest borrowing.

Browning that occurs when amino acids and reducing sugars react under heat, producing flavor and color in seared meat, toasted bread, and roasted coffee. It differs from caramelization, which involves sugars alone.

The browning and flavor development of sugars when heated without proteins, creating nutty, sweet notes in caramel sauce, sautéed onions, and toasted marshmallows. It begins at different temperatures depending on the sugar type.

A protein network formed when wheat flour is mixed with water and worked, giving bread structure and chew. Its development depends on flour type, hydration, and kneading, and it must be avoided in celiac disease.

A stable mixture of two liquids that normally separate, such as oil and vinegar, held together by an emulsifier like egg yolk or mustard. Mayonnaise and hollandaise are classic culinary emulsions.

A food-safety system that identifies biological, chemical, and physical hazards at each step and sets critical limits, monitoring, and corrective actions at control points. It underpins commercial food safety plans and inspection.

The temperature range roughly between 40 and 140 degrees Fahrenheit where bacteria multiply rapidly. Perishable food should be kept outside this range, with prompt cooling and holding practices in food service.

The transfer of harmful microorganisms from raw foods, surfaces, or utensils to ready-to-eat food. Separate cutting boards, handwashing, and proper sanitizing are standard preventive measures.

A written formula listing exact ingredients, quantities, yield, equipment, and procedure so a dish turns out consistently. It supports cost control, nutrient analysis, and staff training in food service.

Nutrients needed in large amounts for energy and body structure: carbohydrates, proteins, and fats. Each supplies a different number of calories per gram and plays distinct roles in growth and metabolism.

A visual nutrition guide showing a divided plate with proportions for fruits, vegetables, grains, protein foods, and dairy. It translates dietary recommendations into practical meal-building proportions rather than strict servings.

Energy from foods and drinks that supply calories with few or no beneficial nutrients, such as sugary sodas and many desserts. Limiting them helps meet nutrient needs within calorie limits.

Limited or uncertain access to enough safe, nutritious food for an active, healthy life, often because of money or transportation barriers. Community programs and nutrition assistance aim to reduce it.

The basic visual components used to build any design: line, shape or form, space, texture, and color. Designers combine them according to principles such as balance, emphasis, and rhythm.

Guidelines for arranging design elements effectively, including balance, proportion or scale, emphasis, rhythm, and harmony. They apply equally to garment construction, interior spaces, and visual merchandising.

A circular arrangement of hues showing relationships such as complementary, analogous, and triadic schemes. Designers use it to plan pleasing color combinations in apparel, interiors, and textiles.

Designing products and environments usable by as many people as possible without adaptation, through features like step-free entries, lever handles, and adjustable lighting. It benefits older adults, people with disabilities, and everyone else.

Ongoing checks during instruction, such as questioning, quizzes, or lab observation, used to adjust teaching while learning is still happening. It contrasts with summative assessment, which judges achievement at the end.

Evaluation conducted at the end of a unit or course to judge how much learning occurred, such as a final project, portfolio, or exam. Results typically inform grades and program reporting.

Planning lessons so content, process, or product can be adjusted for varied readiness, interests, and learning profiles. In FCS labs it may mean tiered tasks, flexible grouping, and varied reading levels.

An instructional approach in which students investigate a complex, authentic question over time and produce a meaningful product, such as designing a budget for a family or planning a nutritious menu within cost limits.

Managing the amount of food served or eaten to match recommended servings, control cost, and reduce waste. It connects nutrition education, food service management, and consumer budgeting.

Family, Career and Community Leaders of America: a career and technical student organization for family and consumer sciences students, offering leadership development, competitive events, and community service projects tied to classroom learning.

The general workplace competencies employers expect across occupations, such as communication, teamwork, dependability, problem solving, and time management. They are often taught alongside technical FCS content and assessed in FCCLA events.

Structured experiences that connect school learning to real workplaces, such as internships, job shadowing, and supervised clinical or lab placements. Clear learning objectives and supervision distinguish it from ordinary employment.
