Ideal electrostatic tool for generating voltages.

Great for classroom demonstrations involving power plants or conversion of energy.

This pen provides a great platform for discovering, playing with, repairing, and designing electronics.

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).

Teach magnetism, motion, Newton's Laws, and more with this fun ball launcher. Simply align these powerful neodymium magnets on a linear rail and arrange steel balls in a sequence for a truly engaging lesson.

The Magnetic Force on a Conductor demo show students how a current-carrying conductor behaves when placed in an external magnetic field.

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.

Comprises an inverted “U” tube with its ends closed by sintered discs. For use in experiments involving the measurement of cell EMF under conditions of forward, zero and reverse current flow. The bridge comprises an inverted “U” tube with its ends closed by sintered discs. This apparatus provides a more effective method of making reversible cells then the wet filter paper or agar gel methods. Dia. of arms 13mm, overall width 80mm, overall height 100mm.
