Interactive Volcano Lessons

After watching some of our 3rd grade students work on Volcanoes in Science class, I started looking around for   some resources and interactive activities and found a blog post that discusses several great resources for students to use to learn more about volcanoes.  I initially started writing this post in the fall and just recently found the draft after I uncovered   Discovery Channel's Volcano Explorer which allows students to simulate and design different aspects of a volcano, like lava makeup and amount of gases contained inside.   When students make their selections the Volcano Explorer provides a short explanation of how those settings will affect the shape of the volcano and its eruption.
