New GCSE AQA Physics lesson on 'Cable and Plugs' written in line with new AQA Physics specification.
For starter different plugs from the around the world can be put in bags to be passed around or a dismantled plug. Pupils are to guess what is in the bag. Following this pupils are to discuss why there are different types of plugs around the world which lead to discussion of the AC/DC war between Edison and Tesla (this part of the lesson can be easily removed if not suitable for the class).
The anatomy of a plug is shown and explained in detail for all 3 wires, colours and function. Safe wiring of a plug is reviewed which leads to a class activity to wire plugs safely. Plug design is reviewed through questioning required properties of different plug parts and appropriate materials to each property required.
How electrical devices can become live or how people can get electric shocks is reviewed and illustrated.
The lesson concludes with a collection of review questions.
Lesson Objectives:
1) Review AC/DC current and how it caused us to have different plugs.
2) Recall the different colour wires in a plug.
3) Relate different wires to their function.
4) Identify and explain the safety features of a plug.
