The children in Hawthorn have started to look at rocks and soils. We have carried out a few experiments using food to represent the different aspects of rock formation. The children grated chocolate to create sedimentary rock and then used the heat, and some pressure from their hands, to form it into metamorphic rock. They then melted some more chocolate in the microwave to represent magma and allowed it to cool which created a chocolate version of igneous rock.
In another experiment they used different types of cereal and some brute force! The children crushed the cereal up and created layers to form an image of the layers of the earth. We added some water for moisture and allowed them to settle for a day before turning them out. We think our experiments worked quite well, just a shame we couldn’t eat any!
