Rocks Under Your Feet

This starter activity from the Institution of Engineering and Technology (IET), provides a quick, engaging introduction to a lesson on the link between sewage and the underground tunnel system. Students identify from a geological survey map, the bedrock on which their town is built.

The study of rocks can be made more relevant to the students by making a connection between the rocks they investigate in their science lessons and the rocks they would find in their local area. This can encourage students to think about the implications that any potential large-scale tunnelling and boring work might have on the bedrock on which their town is built.

This activity accompanies the Shifting Sewage film which looks at the sewage tunnels being built under London, and has been designed for both mathematics and science and can be delivered either independently or through a planned sequential approach.

This resource is supported by a full set of activities in the Shifting Sewage collection.
