Even though volcanoes look alike, they can be very different based on the types of lava that erupts from their surface. Learn about strata volcanoes, shield volcanoes, and the varying viscosity of lava with an engaging hands-on...

Students engage in a lesson which demonstrates that volcanism is the process whereby materials formed inside the Earth come out onto the surface. They participate in a simple, yet effective, activity which demonstrates how volcanoes...

Students examine how gas pressure causes eruptions of explosive volcanoes, and demonstrate how the build-up of gas from dissolving alka seltzer causes the lid of a film canister to blow off. They compare/contrast between the model and...

Students watch and learn the different levels of "viscosity" in liquids to explain molten lava after viewing a video of a Hawaiian volcano.

Students examine the different flow rates of liquids and how lava's viscosity influences flow.  In this liquids lesson students complete several handouts and a lab activity.

Students explore the Ring of Fire. In this volcano lesson, students discuss active volcanoes in the world and explore viscosity as they participate in a hands-on classroom activity.
