In this lesson, students will employ the enzymatic decomposition reaction of hydrogen peroxide to investigate how chemical reactions are affected by enzymes and different substrate concentrations. Students will be challenged to control the rate of the reaction by adjusting the amount of substrate and thus changing the catalase activity. Foam production, created by the enzymatic breakdown of hydrogen peroxide into water and oxygen, will function as a proxy for the reaction rate. Based on their…

An experienced chemistry professor used to say that it took about one explosion per week to maintain college students' attention in chemistry lectures. At that rate, we'd get in pretty big trouble with a lot of parents and teachers! Don't worry, we still have lots of bubbles, fizzes, bangs, and color changes for you to explore.
