"Wards"

Economical set for studying friction.

An assortment of 150 compression and extension springs ranging from 15 to 300 mm in length, 4 to 18 mm diameters, and 16 to 32 swg in wire thickness.

This polished copper calorimeter set has everything you need.

With this stainless steel mirror, students can perform experiments using light rays with plane, concave, and convex mirrors all in one convenient and easy to use tool. The flexible metal curve can be switched to convert from a concave to convex mirror.

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.
