Worksheets and lesson ideas to challenge students aged 11 to 16 to think hard about digestion, the digestive system and balanced diets (GCSE and Key Stage 3)
This is a great demonstration to help students conceptualise the different processes that occur within the digestive system. Use this opportunity to review the differences between physical and chemical changes as digestion is a helpful context to clarify these key terms.
The digestive system
GCSE and Key Stage 3 worksheet on the digestive system. I think it helps students understand digestion if they see the digestive system as one long (0.9 m) tube. First show students this incredible video of the digestive system from the National Geographic. In this activity students draw, label and state the parts of the digestive system, extending the structure from the mouth and finishing at the anus. (PDF)
Nutrients, nutrition and a balanced diet
Key Stage 3 worksheet on nutrients and balanced diets. Students evaluate the healthiness of an inflight snack box by considering the nutrients in each food. They then design their own, alternative and (hopefully healthier!) snack box. (PDF)
