KS3 lesson introducing the idea of electrical power and cost. Will most likely last around 45 minutes. Can be accompanied with a worsheet to last the full hour if needed.

KS4 lesson taking students through the applications and uses of equations to calculate Ke, GPE, and Ee. Each equation is introduced in a way where students begin to think about the equations, and how different factors affect the amount of energy in different stores, before students begin to consider the use of equations in an exam context. Differentiated questions demanding students convert units and consider the form of their answers. What’s more, the final questions require students to interchange values between stores of GPE, Ke, and Ee.
