Foamy Fun with Yeast and Hydrogen Peroxide Free Resource – STEM Scholars Hub

This activity explores the fascinating chemical reaction between yeast and hydrogen peroxide, providing students with hands-on insight into how enzymes catalyze reactions and release energy. By observing the foamy reaction (often called “elephant toothpaste”), students learn about catalase, chemical decomposition, oxygen gas formation, and exothermic reactions, while connecting the experiment to real-life processes in the body and nature.

This topic is ideal for students, teachers, and parents/guardians to explore chemistry and enzyme activity in a hands-on, engaging way. It is perfect for class demonstrations, small group experiments, homework, independent practice, or enrichment activities. Answer keys and supporting materials are provided for guided practice.

Blog about the topic is available on the STEM Blog page, and PDF downloadable resources are down below. PowerPoint presentations and reference videos are found on the PPT/Video page.
