Why do volcanoes erupt?

In Maple class this week we have asked the question… “Why do volcanoes erupt?”

We watched videos of volcanic eruptions and talked about where the name volcano comes from. John was very excited to learn that it came from a Roman god called Vulcan who was the god of fire.

We then coloured and labeled a diagram of a volcano.

We used Plasticine to create all the layers of the earth. We started by making the core and then wrapped it in the outer core and then wrapped it in the mantle. Finally we added the earths crust with sea and land. We then cut them open so we could see all of the layers.
