"Wards"

Consists of one support, 5 plumb lines, 1 roll of tape, and 5 figures (triangle, L, trapezoid, parallelogram, parallelopiped). This kit helps students in the individual research of the center of gravity of a flat body, the conservation of the result on paper, the possibility of a graphic verification, and the discovery of the geometric research method.

Studying dynamic tension has never been easier with this simple form truss kit. The kit includes a half-meter truss with hooks on both sides, V-shaped clamp.Recommended stand and rod, item 470137-892 Required but not included are masses and spring scale.

For demonstrating the differential expansion of two metals as shown by the curvature produced when the bar is heated. Each metal band is 200 x 15mm and riveted together.

Right angle and equilateral prisms are available in a variety of forms.

Spectrometer prisms offer a different index of refraction for every need.

Introduce students to different standing waves.

Measure an electric current by determining the magnitude and direction of the horizontal component of Earth’s magnetic field. Set the compass needle parallel to the coil, pass an unknown current through, and measure the angle of deflection. Features copper magnet wire, adjustable potentiometer, compass, and non-magnetic stand. Required but not included is one D battery.

Made of brass, interchangeable on pillars, fitted with insulators of ebonite on base. Spheres 5cm diameter, Cylinder 12.5 x 5cm diameter, Cone 10 x 5cm length x diameter.

Multiple value resistances with 4mm sockets

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.
