Summer means sunshine and here are a couple of neat projects that you can quickly build for exploring two different properties of the sun: radio spectrum analysis and solar radiation measurement. While both of these projects are very simple in their construction, you can still perform crude data collection with each one. Throw in some exciting solar experiments and now youre talking daytime science fun for entertaining youngsters during the dog days of summer.
