Volcano Eruptions


Students make their own play dough and then, using a 2 liter soda bottle they build a model volcano. The model includes all of the external components as well. The students then use vinegar and baking soda, colored with red food coloring, and erupt their volcanoes. We follow up with detailed discussions on the anatomy of a volcano and how they build up pressure and erupt. We also discuss why the combination of vinegar and baking soda create such a big reaction.
