Take a hands-on approach to teaching students about polarity, conductors and circuits. This comprehensive kit contains materials for 15 individual experiments, each designed to help students discover a specific aspect of electrical flow or magnetic forces. By using common materials, students can see the influence of electricity and magnetism on our everyday lives. Includes: socket, wire, compass and all materials needed to conduct activities, and an illustrated instruction manual. (Please note: One D battery is required but not included.)
