7th Graders Create Exothermic Reaction

7th graders created an exothermic reaction in chemistry class!
During the "Witches Brew Spooky Elephant’s Toothpaste" lab, 7th graders observed a rapid exothermic reaction between yeast, hydrogen peroxide, warm water, and dish soap. Adding yeast instantly triggered the solution to foam and erupt beyond the beaker. To evaluate the process, students tracked both chemical and physical indicators: heat generation, color shifts, and the transition of the initial liquid mixture into a warm, toothpaste-like semi-solid substance.
