Galvanic cells: cell design

Set up and observe the spontaneous redox reaction that occurs between copper metal and silver nitrate solution when they are in direct contact. Then find out how this reaction can be used to generate an electric current. Set up the galvanic cell that utilises this reaction and observe what happens at the anode and the cathode. ...

Galvanic cells: cell reactions

Set up different galvanic cells as specified in given conventional cell notations. Find out the type of reaction that can be used in a galvanic cell, the energy change that occurs and how to interpret conventional cell notation. For each cell, observe the reactions at the anode and cathode at both the physical level and ...

Galvanic cells: electrochemical series

View six galvanic cells built from six different combinations of half-cells of copper, zinc, iron and silver. Observe how the voltmeter needle moves when the circuit is complete, and deduce the direction of electron flow in the external circuit and the polarity of the electrodes. Deduce and record which of the two metals ...

Collection

Energy and forces - early years

This collection of 20 interactive learning objects introduces students to the concepts of forces and energy. It is organised into four categories - energy conversions; forms of energy; energy management; and forces. The learning objects enable students to build energy and food chains, design energy-efficient houses, and ...

Collection

Energy - middle years

This collection of 23 digital curriculum resources is organised into three categories - energy conversions; forms of energy; and energy management. It includes learning objects enabling students to build energy-efficient houses and cars, construct energy chains, harness solar energy for heating, operate nuclear reactors, ...

Collection

Energy - senior years

This collection of 16 digital curriculum resources is organised into three categories - forms of energy; energy conversions; and energy management. Learning objects enable students to build energy-efficient cars; consider environmental and economic implications of a range of energy sources including solar and wind; operate ...

Solahart water heater - asset 1

These are four photographs of solar hot water heaters. The top photograph shows seven solar water heaters on top of the roof of what is probably a factory, with buildings of the city of Perth in the background. The name 'Solahart' can be seen on six of the heaters. At bottom left is a composite of two pictures, the top ...

Solahart water heater - asset 2

This is a colour illustration showing how a Solahart water heater works. It features a smiling-faced sun overlooking a heater that consists of large, flat black plates traversed by pipes, and a storage cylinder with a tap at one end that is releasing water. The movement of water is indicated by arrows, and all the parts ...
