Designed to be used with a maximum of 6V for safety. Used to construct a simple electrical circuit to demonstrate how current depends on resistance and voltage, and also to demonstrate simple parallel and series circuits. Three lamp receptacles mounted ..

Construct simple electrical circuits with or without a switch to learn about the flow of electrical current. Discover which connections are successful and which ones cause a “short circuit.” Includes: 2 “D” batteries, 2 battery h..

Teach students how circuits work with this fully exposed bell! This device rings out when an electrical circuit is completed. Includes: wood stand, banana plug jacks, adjustable hammer, and instructions. Requires an energy source such as a hand generato..

Grades 5-12.
Ideal for introduction of resistance in a circuit. Plastic base features 10 kinds of resistance: 5, 10, 15, 200, 470, 1,000, 2,000, 10,000, 50,000, and 100,000. Connect using 1/8" sockets. 8" x 5" x 1".

Designed to study series and parallel circuits. Five mini lamp sockets are mounted on a 4" x 11" styrene base having 10 connecting posts and eight connecting links. Buss bars connecting the receptacles allow for quick changing from parallel to s..

Grades 2-8.
Create a simple circuit as you learn about electricity, currents, voltages, series circuits, and much more. Includes “D” cell battery holder, knife switch, two light bulb holders, five alligator connector cords, a..
