"Wards"

This condenser box provides different values of Electrolytic capacitors, ranging from 1μF to 4.7μF. Built on a 8 x 5" plastic box. All these capacitors are of ± 10% tolerance and are of 63 volts working voltage.

This pulley is ideal for use with photogates sensors. Pulley is mounted on free-running ball bearings with minimum friction. Mounted on a removeable rod of 150 x 10 mm diameter.
Diameter 65 mm with spokes
Ideal for use with Photogates

Mounted on a wooden stand with a scale, the apparatus is comprised of a three-limbed glass tube with rubber tubing on the center.

Demonstrate the effect of pressure to water depth.

Mounted on molded plastic base, the unit consists of a base into the top of which may be screwed one of a set of four vases of differing shapes. An aperture in the bottom has a thin rubber diaphragm across it, bearing upon the short arm of the lever pointer. A moveable index on the vertical rod enables the height of water in vases to be set at same level. The apparatus is mounted on moulded plastic base that measures 25 x 17.5cm. The experiment is performed by screwing in each vase, in turn, and filling with water to the same level. It will be seen that the given height of water will result in the same deflection of pointer whatever shape of the vase.

Show the difference between three pendulums with different lengths.

Comprised of a thick plastic base with four rubber feet, along with with an 18cm diameter aluminium plate with an insulating handle.

Perfect compliment for a ray box.

Great optical bench accessory.

Accessories for demonstrating properties and laws of motion using linear air tracks.

Demonstrate rotary motion from a charge.

Bridge has broad, heavily plated brass strips mounted on polished hardwood base.

A useful set for density, specific heat and gravity.

Investigate the dependence of pressure on a gas with changes in temperature and volume.
