Learn about electricity and magnets through experimentation! This kit includes the materials needed to bring students from knowledge of basic electric circuitry to an understanding of the use of magnets and how to transform a power generator into an electric motor. Seven "groups" teach students step-by-step (with color illustrations) about the characteristics of a magnet, direct currents, transforming electricity to magnetic field, transforming from magnetic field to electricity, how to generate electric power with the power generator, change the direction of the current by changing the rotational direction of the power generator and changing the magnetic polarity, and supply battery power to the power generator to make it an electric motor. Ages 8 & up.
