Food Safety Lab
Students use the scientific method to investigate the role of temperature in microbial growth. In this food preservation lesson, students set up an experiment with fruit in room temperature and in a refrigerator. They record the...
Curated OER
Bacteria and Illness
Students research information on bacterium and their relationship to food borne diseases. In this science lesson plan, students complete internet research to construct and analyze the growth cure of common bacterium and food-borne...
Learning Games Lab
Understanding Water Activity
How does water activity play a role in food spoilage? First, the learners think about which types of foods would be best to take on a backpacking trip based on the water activity of different foods. It then walks through why water...
Learning Games Lab
Testing and Adjusting pH
Pupils learn how to control food spoilage by adjusting the food's pH. They see that one of the most dangerous bacteria can grow in food if people don't handle and store food properly. Using knowledge of the bacteria's preferred pH,...
