This is a worksheet on the electromagnetic spectrum which covers the uses and dangers of each wave. I have included the information sheets so that they can be used as a marketplace activity. Worksheets are differentiated (3 parts).

I used this lesson with a low ability KS4 class (AQA P1). Contains full differentiated powerpoint with worked through examples. Worksheets to cover each area. I gave them an A3 sheet with a house on, they had to add appliances and identify the inputs and outputs of each and then the calculate the efficiency, from this they could calculate the cost to use each appliance. each task is differentiated. covers: structure of an electricity bill inputs and outputs efficiency cost of an appliance Powerpoint and structure of activity are all my own. Worksheet is created from various sources.
