StoryLab: How Enzymes Work
This story lab aligns to an investigations students do with enzymes where they put hydrogen peroxide on liver and observe bubbles produced from the reaction with catalase. This investigation has several versions for different levels of biology (regular track, intro, and AP) though the story lab was intended for the intro track students who do…

Investigation: How Do Enzymes Work?
This lab is fairly basic, but when given with guided instruction how enzymes catalyze reactions, students can have a hands-on experience into how proteins are related to function.

Investigation: Enzymes
This simple investigation can be completed using materials easily obtained from stores. In a series of tests, students observe how the enzyme catalase breaks down hydrogen peroxide into oxygen and water. Catalase is found in living tissues, but a good reaction can be observed when using chicken livers. The bubbling of the peroxide serves as…
