This week the 2nd and 4th graders built their own volcanoes and simulated an eruption. First they saw how to create the volcano using play-doh to represent layers of hardened rock and ash on the volcano cone. Then they learned and observed how a chemical reaction between baking soda and vinegar could simulate a lava flow. Then they built their own volcanoes and they were able to add the vinegar to create their own eruptions!
