This half-term in Year 3, we have been learning all about rocks. We found out that there are three main types of rocks: Sedimentary, Metamorphic and Igenous. To make things a little more interesting and to help with our understanding of how they are formed, we used Starbursts sweets!
Firstly, we arranged our Starburst pieces into a collection of sediments.
Then we built up the coloured layers to make Sedimentary Rock.
The next stage was to use the heat from our hands and more squeezing pressure to make our Starbursts begin to change shape and fuse together to form Metamorphic Rock.
The final stage was to simulate the Metamorphic rock being pushed deeper underground where it is heated to become molten magma.
We heated our Metamorphic Starbursts until they became even softer (almost a liquid) and then allowed them to cool. The result was a shiny substance where the sugar had begun to crystallise – very similar to the crystalline structure of Igneous rock!
We had a fabulous time doing this activity and even had some left over to eat afterwards.
