I'm in need of sources for KS2 level information on radio waves and Antennas.
The reason is that my son wants to do his science project on receiving NOAA satellite weather images with a homemade antenna. I've all the parts; RTL-SDR, materials for the antenna build (This one which is about as simple as it gets for 137MHz), Raspberry pi and the software that is needed.
The only thing that is missing in some materials at KS2 level to try and help him understand how radio waves and antennas work. Is anyone aware of any materials that would be suitable?
