In Year 3 this term, we are studying the ‘Extreme Earth’. We have learnt that the Earth’s crust is not solid, but made of plate margins that are moving all the time. At some of these margins, volcanoes occur as is the case with the Ring of Fire in the Pacific Ocean.
Volcanoes occur when pressure builds up under the surface and erupts. Year 3 used the analogy of a cola bottle and mint sweets to observe the idea of pressure building and erupting. They were interested to learn the story of the Roman God Vulcan, from whom we get the word ‘volcano’.
