This lesson recaps what materials are and different examples. It then focuses on why materials are chosen for specific purposes, the properties of materials to suit a particular purpose (e.g. why we wear clothes made out of cotton), and ultimately the lesson focus is to compare different materials and conduct experiments to select the best material for a bike seat.

Included is a whole lesson presentation and worksheet for comparing the materials.
