Learning about Earth's interior

After the students used clay to make mini-volcanoes, we will discuss the variety in their results and how important it is to keep in mind that not all volcanoes look the same. Volcanoes will form differently based on many reasons.
Tuesday we used baking soda and vinegar and "erupted" the volcanoes. The students observed the different results based on the "flow" of the baking soda/vinegar lava.
