Using easily available materials, students can show off their smarts by comparing evaporation indoors and out, predicting weather by wind direction, and designing paper airplanes for distance. They'll be amazed at what they can do! #65533; Change the sun's light into heat energy: Take one hot day, ice cubes, a clear-colored soda, and some cola.
