Students in Ms. Dobler’s STEM club worked to understand the classic chemical reaction by creating elephant toothpaste, which uses soap, hydrogen peroxide, yeast, and water. The hydrogen peroxide breaks down into water over time, and the yeast is added as a catalyst to speed up the reaction. After following the “directions” the first time, students were able to ask their own questions, so they experimented with things like using more or less of the materials to see what would happen.The club meets 12:15-12:45 every Monday and Friday. Mondays are choice days, with 4 or 5 different activities to choose from, ranging from programming, design, and engineering. Friday there is one bigger activity that is led. This Friday’s big activity will be an introduction to the 3D printer!
