1. Read the song lyrics below and start to learn them!
Radio waves are long wavelength, and low frequency
Microwaves are used to heat out food, so it’s safe for us to eat
With infrared here and visible there, ultraviolet radiation everywhere,
The electromagnetic spectrum
Transverse waves are we!
This will be sung to the tune of old MacDonald's farm!

2. The electromagnetic Spectrum Objectives
To know the waves that are in the spectrum (Knowledge)
To be able to explain the uses of the waves (comprehension)
To survey the uses of em waves in different jobs (Synthesis, evaluation & HSW)

3. Present New Information
A spectrum of transverse waves
Can travel through vacuum
Travel at m/s in vacuum
Many everyday uses

4. H/W to complete an EM spectrum Overview Picture
It should include:
The wavelengths (roughly)
The waves in the correct order
Uses of the waves
Dangers of the waves (you are going to find this out at home using the website below)
Diagrams
Let’s look at some examples:
Write it in your planner

6. Construct – 15 minutes You’re now going to use multimedia science to find out about the electromagnetic spectrum - collect your core or challenge sheet

7. Mini Review: What did you learn
Mini Review: What did you learn? 5 minutes Discuss two of the following questions
B/C grade
How many em waves do you think you’ve used today? Give examples of them!
C/D grade
What does long wavelength mean?
A grade
Think about a career you might wish to pursue – which of the waves does it use? How do you think they’re used? Why do you think the wave is appropriate?

8. Apply to demonstrate Success Criteria
By the end of the 40 minutes you will have an overview of how each of the waves are used by Y10, and which are used most frequently.
You’re going to create and complete a survey on the uses of em waves in Y10 everyday life!!
You will need to write the questions you will ask, then collect the data, and then write a conclusion, summarising it
15 mins to write
15 mins to collect data
10 mins to analyse & conclude

9. Sharing our findings  Tell the person next to you what you found out
Pair! – 1 minute
Share! Now be ready
to tell the class

10. Plenary – let’s learn this song then!!
Radio waves are long wavelength, and low frequency
Microwaves are used to heat out food, so it’s safe for us to eat
With infrared here and visible there, ultraviolet radiation everywhere,
The electromagnetic spectrum
Transverse waves are we!
Xrays are used to see our bones, and in airport security
Gamma rays are very dangerous, ‘cause they’re such high frequency
They can travel through water, they can travel through air, they can travel in a vacuum or anywhere
The electromagnetic spectrum
Transverse waves are we!
