Learning journey
Your child is discovering how their body works — exploring the respiratory, circulatory, and nervous systems in detail, and understanding how lifestyle choices affect their health and development.
Evidence of understanding
- Explain how regular exercise strengthens the heart, lungs, and muscles
- Describe how a poor diet high in sugar and fat can lead to obesity, tooth decay, and heart problems
- State at least two harmful effects of smoking (damages lungs, increases heart disease risk) or alcohol (damages liver, affects brain)
Assessment prompt
Can Healthy Lifestyle Choices explain how what they eat, how much they exercise, and how much they sleep affects how their body works — and why smoking or drugs are harmful?
