Teaching Time: 50min

Target Group: Key Stage 2

Curriculum Links:

Science: Working scientifically; Living things and their habitats

English: Reading and Comprehension

PSHE: Core Theme 1 - Health and Wellbeing

Design and technology: Cooking and nutrition

Learning Objectives:

All students will:

  • understand that microbes can be found on our food and can transfer to humans.
  • understand that cooking food properly can kill harmful microbes.
  • understand that bacteria multiply very quickly.

Some students will:

  • understand that refrigeration only stops microbes growing, it doesn’t kill them.


This Food Hygiene lesson demonstrates how dangerous microbes can infect humans through raw and undercooked foods.

Activities include:

  • Students prepare a pretend chicken sandwich that allows them to see how far they have spread dangerous microbes.
  • Worksheets facilitate a discussion on “do’s and don’ts” for kitchen cleanliness and management.
  • The Fridge Game can be used as a classroom game/demonstration to show where food should be stored in the fridge to prevent cross contamination.
