This web site contains a set of science fair projects and experiments for teaching the basics of electricity, electromagnetism, and electronics using hands-on activities with circuits and batteries.

Following the construction of a simple "power pack" of two D batteries in series, materials such as a quiz game buzzer, flashlight, compass, electromagnet, galvanometer, or simple telegraph set may be built.

All lab activities use safe, low-voltage battery power and most do not require the purchase of complex materials. Additional links are available to reference materials on the design and history of batteries.
