We’ve been looking at the EM spectrum this week which is difficult with SEN students who find the idea incredibly hard to grasp.
To make this topic more hands on we’ve done a series of practical lessons looking at different types of waves. Perhaps you’ll have time to squeeze a few of these in – they do make a dull topic more fun.
Investigating properties of radio waves using a mobile phone by using Bluetooth to send photographs to each other (check your school policy on mobile phone use first!).
Factors which affect Bluetooth signals (worksheet)
Measuring the speed of light using a microwave oven
Using a digital camera to view the infrared signal from a DVD remote control.
Spectrum – splitting white light using a prism.

Ultraviolet sensitive beads (work in sun or with a UV lamp). Also looking at security markers, money, credit cards etc under UV light.
