*Explain the energy transfers in a system by producing a Sankey diagram.
*Apply calculation to find the efficiency of a device.

Are your students aiming above a grade 5? Stretch them to:
*Link the design process for a device to explain how you could improve the efficiency.

This resource includes little extras to help challenge all of your students.
