Books in Seasonal Science Projects series

"This practical book offers 46 projects...exploring electromagnetic forces, static electricity, current flow, electromechanical devices and motors, resistance and capacitance, the generation of electricity, solid-state electronics, and radio-frequency energy....Using materials that are relatively easy to find, the activities encourage children to learn about electricity through simple experiments and variations....The large format allows each project to appear on one page or spread, eliminating page flipping....Illustrated with simple line drawings, the book provides a good starting point for classroom learning and science fair demonstrations."--Booklist. Experiments designed for safety. 96 pages, 8 1/4 x 11.
