Hyman Fire Piston
This apparatus vividly demonstrates the rise in temperature that occurs when a fixed mass of air in a transparent cylinder is compressed by a hand operated piston. A piece of tinder, which is provided, ignites in the transparent cylinder: much as a diesel engine obtains ignition. The cylinder and piston can also be used to demonstrate the effect of decompression, being the immediate lowering of temperature and the consequent condensation of water vapour inside the cylinder the cloud formed can easily be seen. Cylinder Dimensions: (L) 198.00 mm (OD) 15.00 mm (ID) 9.00 mm

Bimetallic Compound Bar, Premium
An improvement on the riveted version, this bonded copper and steel bimetallic strip comes mounted in a wooden handle for ease of use. Heating on either side causes the strip to bend as the two metals expand by different amounts. Comes with instructions. Dimensions (L incl. handle): 300mm); Bimetallic Strip (L x W) 200 x 13 mm.

Motor/Generator Unit
This unit can be used for variety of purposes to illustrate energy transfers: it can be used to lift mass or stretch bungee cord, and to generate an electrical current when the mass falls again or the bungee cord is released. It can also be turned by hand to generate current. The motor/generator (6-9 V) is mounted on robust metal base, and the gearing of the unit and the sizes of the pulleys have been chosen to enable variety of qualitative and quantitative experiments to be undertaken.

Energy Transfer Unit
Developed for the Science Enhancement Programme (SEP) this single unit demonstrates range of different energy transfers; for example, how energy is transferred electrically from hand-turned dynamo to motor. The unit is accompanied by booklet that discusses some of the key teaching and learning issues that surround the energy concept, and provides series of activities that illustrate how the unit can be used to develop simple and coherent ways of talking about energy.

Solar Educational Kit, Modular
A kit comprising 8 solar modules, low-inertia motor, impeller, connecting lead and copper links for cell interconnections and housings and brackets to enable the construction of various solar powered projects. The modular concept of this kit enables experimentation with differing voltages and currents to produce the required circuit. The kit also includes comprehensive booklet covering principles of solar power, together with useful connection diagrams and output calculation formulae.

Stirling Engine, Low Temperature
An affordable Stirling engine which works at very low temperature differences. A cup of warm water (must be at least 60 °C) can make the motor run, which means that water heated by sunlight can become hot enough to drive this motor. Like other Stirling engines, this type works by converting temperature differences into mechanical energy as warm air expands and cold air contracts. This is utilized in closed system where the same air is pumped back and forth between cold and hot engine part. Illustrates perfectly how Stirling engines operate and can be used with many different heat sources. Weight: 330 g. Dimensions (H x W x D): 144 x 90 x 90 mm.

Ice Melting Kit
Demonstrates the difference in conductivity of two different substances. Comprises two identical looking square blocks but of different materials, one of thermal conducting material and other of thermal insulating material. On placing ice on both of them, ice melts faster on one of them showing the difference in their conductivities.
