After researching the types of volcanoes, have students devise their own plans for making a model of each. They may choose whether or not to actually construct the models. Back to Top 1. Explain how heat built up when Earth first formed. Speculate on how it might be sustained.
Hawaiian volcanoes produce two types of the same variety of lava.
Formulate a hypothesis as to why the same lava can have two different appearances. Explain how gas concentrations could possibly signal a volcanic eruption. Compare Kilauea to White Island volcano. Describe the danger in an eruption such as the ones at Mt. Pinatubo and Mt. St. Helens. But not all lava is the same.
