Micronutrients and water are the 'silent workers' of the human body. While needed in smaller quantities than macronutrients, vitamins and minerals are indispensable for metabolic processes, bone health, and immune function. This topic explores the classification of vitamins into fat-soluble and water-soluble categories, as well as the vital roles of minerals like calcium and iron. Water is treated as a critical nutrient, essential for temperature regulation and waste transport.
Activity 01
Set up stations representing different patients with symptoms like scurvy, rickets, or anemia. Students move in groups to diagnose the deficiency and prescribe specific local foods rich in the missing micronutrient.
Why are micronutrients essential despite being needed in small amounts?
Activity 02
Students create posters explaining the role of water in different body systems. They rotate to view others' work, adding 'sticky note' questions or facts about how Singapore's tropical climate increases hydration needs.
What are the consequences of vitamin and mineral deficiencies?
Activity 03
Students consider how washing or boiling vegetables affects water-soluble vitamins. They discuss their thoughts with a partner before the teacher demonstrates the science behind nutrient loss during food preparation.
How does water regulate bodily functions?
A few notes on teaching this unit
Watch Out for These Misconceptions
If a little bit of a vitamin is good, a lot must be better.
Students often assume supplements are always beneficial. Through collaborative investigation of toxicity (especially for fat-soluble vitamins), they learn that the body stores certain vitamins, which can lead to harmful levels if over-consumed.
Thirst is the only indicator of dehydration.
Many believe they only need water when they feel thirsty. Using a peer-teaching approach to explain the physiological signs of dehydration (like urine color or fatigue) helps students understand that thirst is actually a late-stage signal.
Methods used in this brief
Macronutrients and Energy Balance
Students will explore the roles of carbohydrates, proteins, and fats in providing energy. They will evaluate how energy balance impacts overall health and weight management.
8 methodologies
Diet and Health Conditions
Students will analyse the relationship between diet and diet-related diseases such as obesity, diabetes, and hypertension. They will plan modified diets for specific health conditions.
