This resource is a fully differentiated lesson aimed at teaching the new AQA GCSE Physics and Trilogy Physics specification, and links to Internal Energy and Energy Transfers. This lesson has 5 learning objectives that are structured in the IDEAL format: *Identify how you can find the specific heat capacity for a material. *Describe a practical that you can do to test the specific heat capacity of a metal. *Explain how the energy required to heat a material changes with specific heat capacity. *Apply your understanding of efficiency to calculate how efficient your practical is. *Link your understanding of metallic structures to explain why metals tend to have lower specific heat capacities than none metals. This lesson is designed with a challenge objective and challenge questions throughout to stretch your most able students, whilst supporting your LA students. Review the lesson before teaching to see how the animations and objectives will work in your lesson. Enjoy! V1.01 - Update to some of the animations in the powerpoint.
