This 17-minute DVD is meant to help teachers use the Van de Graaff generator in demonstrating the principles of static electricity. The program shows twelve accessories in use with a clear explanation that connects to the physical laws involved. It will show how each demonstration should look when the machine is operating properly. In addition, there is an extensive text which gives a complete description of each demonstration.
