Maths KS4

Explore mean, mode and median using test data for a Tunnel Boring Machine to plan an inspection schedule. Use the geometry of circles and cylinders to calculate how much concrete will be needed to make the Tunnel segments. Explore how to model some simple real-life situations using graphs of the form y = mx + c.

Dig Deeper ideas explore grouped frequency tables and cumulative frequency and extend segments and sectors into 3D to consider the volume of water stored in the Tunnel. Can students model the total time to load and unload multiple barges, allowing for docking and undocking times and to load each barge in turn? 

Research projects: research and design a fan system to maintain a constant airflow through a pipe or build a prototype or proof of concept demonstration for an autonomous Tunnel Inspector.
