This complete set of materials makes possible multiple dramatic demonstrations of basic electrostatic principles.

The Current Balance is an excellent tool for studying electric currents.

Perfect for density experiments, use this set determine the mass and volume of each sample and graph the mass versus volume. The slope of the straight line that results is the density of the material.
