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 its 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 MacDonal d'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 300000000m /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 Lets look at some examples: http://www.darvill.clara.net/emag/ index.htm Construct 15 minutes Youre now going to use multimedia science to find out about the electromagnetic spectrum - collect your core or challenge sheet L ig h t t r a v e ls a s a w a v e .
