"Janitorial Supplies"

This set demonstrates a wide variety of physical science topics including the resolution of forces on an inclined plane, kinetic and potential energies, uniform and accelerated motions, and the friction between two surfaces.

Six aluminum replacement leaves for the Electroscope Assembly without Flask.

This large Van de Graff generator uniquely offers alternative drive modes, either hand-cranked or motor driven.

Miniature DC motor designed for experiments using low starting voltage (4.5 V) and current (70 mA).

Starter kit containing all the popular size connecting wires for use with a breadboard.

Tradiitonal lever switch for circuit experiments.

Complete electricity kit in a convenient storage case.

Four gears of different sizes, perfect for any investigation or maker project.

Versatile teaching kit contains enough materials for the whole classroom to learn about and experiment with a variety of pulley configurations. Because these activities are hands-on, students get a real feel for the forces at work.

This package of plastic pulleys contains 25 each of 20, 30 and 40 mm diameter pulleys with 3.2 mm bores and one 10 mm pulley with a push fit to a 2 mm motor shaft.

Demonstrate magnetic fields on your desk or overhead with this clear container of iron fillings. Using magnets, you can show students how the fillings move and cluster together.
