This primary resource introduces children to the human digestive system. Discover what happens to our food once we’ve eaten it. How strong is the acid in your stomach? How many jobs does your liver have to carry out? Why do we have an appendix?

Pupils will learn about the different organs that make up the digestive system and what their functions are in our National Geographic Kids’ Science primary resource sheet.

The teaching resource can be used in study group tasks for discussion about food and nutrition.

It could be used as a printed handout for each pupil to review and annotate, or for display on the interactive whiteboard using the images included in the resource for class discussion.

Activity: Ask children to use the facts provided to discuss why we need to eat healthily. Pupils could be given a diagram of the digestive system to label, using the resource sheet to help them. As a class exercise, show the children pairs of images of food and ask them to pick the one that is most nutritious, giving reasons for their answers.


N.B. The following information for mapping the resource documents to the school curriculum is specifically tailored to the English National Curriculum and Scottish Curriculum for Excellence. We are currently working to bring specifically tailored curriculum resource links for our other territories; including South Africa, Australia and New Zealand.
