Excellent inquiry based activity through which students in upper elementary through college can make observations about the patterns of features on Earth’s surface—and draw conclusions about Earth’s tectonic plates.
After having vinegar/baking soda eruptions, students use Play-Doh to mark where the lava flowed. In teams they examine the stratigraphy and map the flows.
Why does Earth have active volcanos and the Moon does not? Students experiment with different sizes of hot water containers to explore which cools first, and what this suggests about planetary history and volcanic activity.
