Rock cycle at your fingertips

Today's new ELI is 'The rock cycle at your fingertips; modelling the rock cycle with your fingers'

The rock cycle is an abstract concept which pupils can find difficult to understand. For example, when asked how a rock formed, one student responded, “It went through the rock cycle” much as laundry goes through a wash cycle – something that is done to a rock to change it.’ This activity helps to explain the process.
Other teaching ideas about the rock cycle and many suggestions for hands-on activities, can be found on our website.
