2. Click on the picture and then move the circle as you read about the different parts of the electromagnetic spectrum.

3. Drawing the electromagnetic spectrum
1. Collect a sheet called ‘Drawing the electromagnetic spectrum’ 2. Your teacher will read out 7 statements about the parts of the spectrum. Listen carefully and draw a simple picture that represents each statement in the appropriate grid square on your sheet. Your pictures do not need to be works of art and the occasional word or number is OK. 3. Once all 7 statements are read out, write a caption for each picture. 4. In pairs, discuss what you understand about the electromagnetic spectrum using your pictures and captions as prompts. 5. Collect a copy of the electromagnetic spectrum statements to read through as you check your understanding of the electromagnetic spectrum.

4. Discussion questions
1. What is happening to the wavelength as we move through the electromagnetic spectrum, from radio waves to gamma waves? 2. Electromagnetic waves carry energy. The shorter the wave, the more energy it carries. Which has more energy – X-rays or microwaves?
