Secret Lab 1: Volcanoes

Find out about erupting volcanoes

Factual series explaining all the mysteries of the world of science in BSL! In this episode, Professor Knowitall and his sidekicks Dr Spark and Dr Bright look at the awesome power of volcanoes. How are they formed, and what comes out of them? Professor Knowitall shows us the earth’s crust and how it is made up of incredibly hot liquid iron, which radiates heat. It is magma that is nearer the surface that shoots up during a volcanic eruption. Meanwhile, Dr Spark goes climbing in Snowdonia in Wales to show how lava turns into solid rock. Aimed at children of Key Stage 3 level. Don’t miss it!
