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 Mac. Donald's farm!
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)
Present New Information A spectrum of transverse waves ► Can travel through vacuum ► Travel at 30000 m/ s in vacuum ► Many everyday uses ►
H/W to complete an EM spectrum Overview Picture ► It should include: Write it in your planner 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: ► http: //www. darvill. clara. net/emag/index. htm
Construct – 15 minutes You’re now going to use multimedia science to find out about the electromagnetic spectrum - collect your core or challenge sheet
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?
Apply to demonstrate You’re going to create and complete a survey on the uses of em waves in Y 10 everyday life!! You will need to write the questions you will ask, then collect the data, and then write a conclusion, summarising it Success Criteria By the end of the 40 minutes you will have an overview of how each of the waves are used by Y 10, and which are used most frequently. 15 mins to write 15 mins to collect data 10 mins to analyse & conclude
Sharing our findings ► Tell out the person next to you what you found ► Pair! – 1 minute ► Share! Now be ready to tell the class
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!
