"Wards"

These robust and engaging kits are designed as a resource for the teaching of introductory electricity.

This complete set of materials makes possible multiple dramatic demonstrations of basic electrostatic principles.

The concept of electric fields can be difficult to visualize, but the Dry Field Mapping Kit makes it easy.

No need to Buy New Magnets

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.

Oersted's Apparatus demonstrates the magnetic field created by a current.

Enhance your electroscope with these fine gold leaves.

Economical set for studying friction.

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.

Economical set for teaching the basics of circuits
