Teacher Developed

Employs Guericke’s Method for Demonstrating the Force of Atmospheric Pressure.

A small scale demonstration of renewable energy, this wind generator can be used with a voltmeter or datalogger to measure and monitor output.

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.

This gyroscope will spin for several minutes.

Quality Lamp Receptacle.

Ideal for small pulley systems, cord is available in a variety of colors, strengths, and lengths.

For your Electrostatic Needs!

Perfect for demonstrating anchoring as well as connectivity, if one student puts a finger on one contact, another student puts a finger on the second contact and both then hold hands, the ball will light up.

A bare copper wire of the highest quality. Available in several standard AWG sizes.

A high quality enameled, copper magnet wire.

A good quality bare iron wire. AWG 20.

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.

Nine level conductivity meter shows the relative conductivity/resistance of liquids and solids. As the conductivity of the tested material increases, the number of glowing red LEDs will increase to a maximum of 8, which indicates a very good conductor. There will be zero glowing red LEDs if the material has a very low electrical conductivity (is a good insulator).
