Learning Games Lab
Controlling Water Activity in Food
Food storage matters! Scholars learn how the amount of water in corn can affect its rate of spoilage. They create a control group, then test three corn samples stored in three different locations for water activity. As a result of the...
Learning Games Lab
The pH Scale and Meter Calibration
What are the different ways to test for pH? First, scholars explore the pH scale and a common way to test for acidity and alkalinity. Then, they learn about the importance of pH in food safety and why variance in pH could potentially...
Learning Games Lab
Gram Staining
Scholars use a lab simulation to test contaminated yogurt for bacteria by gram staining. They learn proper lab procedures for handling bacteria and for sterilizing equipment, and then walk through the process on their own to try gram...
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,...
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
How to Use Oil Immersion Microscope
Teach the class how to use a microscope to identify bacteria in food. Scholars explore the different parts of the microscope and learn how to determine total magnification. They walk step-by-step through the procedure of preparing slides...
