GCSE AQA Physics - P1.8-9 -  Electrical Appliances, Energy and Power
New GCSE AQA Physics lesson on 'Energy and Power of Electrical Devices' written in line with new AQA Physics specification.

Starter gets pupils discussing common electrical devices and the useful and wasteful energy transfers they make.
To start looking at Power pupils discuss what power means for familiar figures.
Main includes a clear description of what Power is in Physics and an explanation of the units. This lead onto clear example of using the equation and to a classroom activity looking at power rating of electrical devices and making energy transferred calculation from them.
Included is a review of the power efficiency calculation with examples.
A task sheet allows pupils practice use of the lessons knowledge.
A final line of questioning draws on knowledge of previous topics to review and consolidate content.

Lesson Objectives:
1) State and explain what power is and the unit for power.
2) Relate power ratings to different electrical devices.
3) Calculate power rating of electrical devices.
4) Calculate the energy used and wasted by devices and therefore their efficiency.

Worksheet includes 'Energy & Power' task to be printed on one A4 sheet to save on printing. Set-up to print '2 pages per sheet' to produce one worksheet.
