Description
Detect an approaching thunderstorm. Build a generator. Harness the power in a potato. Keep insects away with sound waves. Find out if it is really dangerous to sit too close to the TV set. Sixth through ninth graders can impress teachers, classmates, and science-fair judges with any of more than 40 fantastic projects that explore electromagnetic forces, static electricity, current flow, motors, resistance and capacitance, generating electricity, solid state electronics, and radio frequency energy. Designed to ensure safety, most of the projects can be completed with readily available, inexpensive materials and supplies commonly found around the home. Following the illustrated construction guidelines, each exploration includes a series of questions to stimulate thinking and further activities.
