Have you ever wondered how all the food that you eat gets digested? It is not only the acid in your stomach that breaks down your food – many little molecules in your body, called enzymes, help with that too. In this activity you will explore the foam-creating enzyme catalase. How much foam can you make? Written instructions are available on our website at https://www.sciencebuddies.org/stem-activities/explore-enzymes-catalase?ytid=FxjXrCyic6o&ytsrc=description

Explore how enzymes work in three simple experiments using toothpicks as a model for enzymatic activity. In experiment one discover what happens to enzyme activity over time. In experiment two explore how changing the substrate concentration effects enzyme activity. And in the third experiment see how temperature alters the enzymatic activity.
