Teaching Nutrition and Digestion in KS3 Science

Pupils name the seven parts of a balanced diet and their jobs, sort everyday foods by nutrient and describe the effects of obesity, starvation and deficiency diseases such as rickets and scurvy. They follow food through the organs of the digestive system, match carbohydrase, protease and lipase to the molecules they break down, explain absorption by villi and describe how gut bacteria help us.

• Name the seven nutrients in a balanced diet and what each one does.
• Describe the effects of an unbalanced diet.
