Five single slits of different widths in a slide frame.

A useful tool for measuring the magnetic field strength for experiments. The range of the probe is 200 and 2kG with a resolution of 1G at 0 - 200 G. The included probe is a hall probe, which is a flat style probe to fit into small gaps.

Visually illustrate the difference in specific heat.

All in one unit for studying pressure, temperature and volume of a gas and to demonstrate the relationship between them.

This extra large electroscope is ideal for classroom demonstrations of electrostatic principles. A lightweight metal vane is used as a pointer in the electroscope. This lightweight metal blade deflects when the electroscope plate is charged. A transparent scale is provided to measure the angle of the deflection. Front glass window slides up to allow insertion of ionizing material in chamber.

This TeacherGeek Mini Hub is designed to slide directly on a motor shaft. It is comprised of two parts that are held together with a single screw. This allows you to secure 2, 3 or 6 turbine blades. When the hub is mounted on the motor shaft and driven by the wind, electricity is generated.

A pair of 100g gliders designed for use with air tracks 470157-654 and 470157-664.
