Home Economics - MATSEC SEC
The SEC Home Economics syllabus tests four linked areas: food and nutrition, family and consumer studies, textiles and clothing, and housing and home management. Questions rarely ask you to recite a list; they place you in a situation - a family on a tight budget, a toddler who refuses vegetables, a shirt whose care label you must interpret - and expect you to apply principles and justify your choices.
Core rules and concepts
- Energy and nutrients: carbohydrate and protein supply 4 kcal per gram, fat 9 kcal per gram (alcohol 7). Reference intakes are averages for a group, not targets for one person.
- Meal planning: balance across the day, variety, seasonal and local produce, cost per portion, and adaptation for dietary needs (coeliac, diabetes, vegetarian, allergies).
- Food safety: keep high-risk foods out of the 5–63 °C danger zone, hold fridges at 5 °C or below, freezers at −18 °C, and cool cooked food quickly before chilling.
- Consumer studies: distinguish needs from wants, calculate a budget surplus or deficit, and know that "best before" is about quality while "use by" is about safety.
- Textiles: fibre properties (cotton absorbent but slow-drying; polyester strong but heat-sensitive) must match the care label instructions.
Worked example
A 15-year-old girl has an estimated requirement of 2,000 kcal a day. Her breakfast supplies 60 g carbohydrate, 10 g protein and 15 g fat. Energy = (60 × 4) + (10 × 4) + (15 × 9) = 240 + 40 + 135 = 415 kcal. As a share of the day: 415 ÷ 2,000 × 100 = about 21%. The reasoning matters as much as the number - convert grams with the correct factor for each nutrient, then express the result against the daily reference figure, not against the meal.
Traps that cost marks
Using 4 kcal per gram for fat; quoting a "serving" when asked for a portion; treating "best before" as a safety date; listing ingredients in a budget answer without costing them; and describing what to do without saying why.
