KS3 You are what you eat

Science Unit: The Science of Food


This Science unit looks at the chemicals in the food we eat and that make up our body. This unit includes some standard lab food tests and an overview of the make-up of our bodies with an option to explore further the digestive system. There is an opportunity to explore the science in growing our own food, including photosynthesis and germination as well as practical gardening.  Cooking is used as a context to explore chemical changes, with opportunities to use science in the kitchen.

Learning Intentions: Science

  • Learn about organisms and health
  • Learn about chemical and material behaviour
  • Develop a range of practical skills, including the safe use of science equipment
