Make a Volcano

This resource is a guide to building a volcano out of clay.  The reaction between vinegar and baking soda simulates a volcanic eruption. This resource is to a lesson that can be used to teach both chemical properties and reactions, but also major geological features.  The students can observe the physical and chemical properties of vinegar and baking soda and then also the reaction between the two.  The students can create their own volcano and simulate an eruption in a controlled setting.  The materials are easily acquired and inexpensive.
