The hardest part of a science fair is the week spent picking a topic, by which point there is no time left to do it properly. Draw a project and start gathering materials the same evening. Thirty investigations using things most homes already have, each with a real variable to test rather than a demonstration to perform. Teachers handing these out by draw get thirty different projects instead of nine volcanoes, which improves the evening for everybody.
