Every time I teach Biology we do food tests. Identification of Biomolecules. This lab has a good data sheet which allows students to mark down their predictions. Biomolecules are also called macromolecules. Here is a Google slide deck demonstrating positive tests for carbohydrates, lipids, and proteins. These tests require Benedict’s solution and biuret solution. Home Science Tools has both. What is the point? I like to reinforce concepts. This lab introduces kids to identifying substances with test reagents. (BTW, the orange beakers are for wastes.)
