Pupils needing extra support:

Could use the diagram on the Presentation: Blender bike to help them draw their design; could use the Knowledge organiser to help them choose the size, layout and orientation of gears on their design. 

Pupils working at greater depth:

Could draw the bike onto their mounting board and be provided with corrugated card, scissors and split pins to make additional gears to complete the prototype; should create a 30-second video clip explaining how the eco-gadget bike will work using the gear and pulley prototype.
