New GCSE AQA Physics lesson on 'Internal Energy' written in line with new AQA Physics specification.
Lesson Outline:
Starter discussed whether a glass of water has energy of not to see what conclusions pupils can draw on this from previous lessons. This leads to a view of a substance on a microscopic scale to highlight that the particles are moving, therefore pupils should be able to deduce must have energy in order to move. Internal energy is then shown to be this energy in substance due to kinetic energy and potential energy. After revisiting the starter how to increase internal energy is discussed The different states of matter are review again but now in relation to internal energy with helpful graphics to support these points. How much energy in a substance is related to specific heat capacity which is typically covered earlier in the course so this provides a great opportunity to review of this topic. Lesson concludes with review questions.
Lesson Objectives:
- Explain what is meant by internal energy.
- Identify and explain how you can increase internal energy.
- Relate internal energy to properties of solids, liquids and gases.
- Explain how particles in a gas exert a pressure.

Great resource
I've downloaded a few of these resources now and they've all been fantastic. A massive time saver, thank you.
Thanks this is a very clear and thorough powerpoint. Life saver when too busy to prepare the slides yourself.
