Volcanoes!

4th graders have been learning about changes to Earth's surface (fast and slow processes). We watched a short Discovery Education clip on the three types of volcanoes and then the kids worked in groups to build a volcano. We used math to measure the diameter and height of the volcanoes. After we erupted the volcanoes, students measured the flow of "lava" that erupted. The activity was so much to teach the kids about landforms.
