Science Fair Projects: Energy

Grade 4-6AAlthough there are several interesting activities here, most are very basic and it is questionable whether they are really up to science-fair standards. Most are quick demonstrations or parent/child activities that focus on basic energy-related concepts. Several are devoted to exploring energy transfer and storage in different materials. A few are somewhat odd, requiring only paper and pencil, suggesting that readers categorize home appliances, list ways to conserve fossil fuels, learn to read an electric meter, list items that could be unplugged without causing inconvenience, and enumerate ways to save energy at home and school. While these are all admirable goals, they do not really constitute experiments. Many are, however, a lot of fun. There are also a few simple wiring projects involving batteries, lamps, and even solid-state components that are fascinating and teach electronic principles. There is even an attempt at practical skills, as youngsters are encouraged to learn how to calculate the cost of operating different electrical devices. Instructions and diagrams are down-to-earth and clear but very brief. Concluding questions help students evaluate the results of the activity. Safety concerns are repeated frequently, and when adult supervision is needed, the list of necessary equipment includes "an adult."
