Bubble escape and drag race for schools

here are many different types of volcanoes. Shield volcanoes have a broad rounded shape and gentle splattery eruptions often described as fire fountains. Strato volcanoes are sharp and steep sided and have violent explosive eruptions. But what makes these two types of volcano look and erupt so differently? It is mainly controlled by how think (viscous) or runny the magma in the volcano is...

In this experiment you can use 3 different thickness (viscosity) liquids to see what differences runny or thick magma can cause in volcanoes.

Vinegar Volcano for schools

Volcanoes form when hot molten rock (magma) under the ground erupts at the surface, but what causes the molten rock to erupt? Eruptions are often driven by gases escaping…

In this experiment you can start a chemical reaction that creates a gas, and see how the gas escaping drives an eruption.

This experiment and video was devised by the Volcano Seismology group in the Earth Science Department, University of Cambridge.
