Transporting Energy

Materials Required:

1. Miniature 6-volt hobby lamps
2. Lamp sockets
3. Hookup wire
4. Jumper leads with alligator clip ends
5. Six-volt lantern battery with spring top connectors
6. Modelling clay
7. Ice-cream bar flat sticks
8. Glue or adhesive tapes
9. Toy-buildings
10. Scissors
11. Screwdrivers

The electricity that burns the lamps at home is the result of energy changing forms several times, as it is being transferred to the end use from a great distance.

There are several sources to create this energy at the power plants. Some plants use the heat available from burning fossil fuels, which is then converted into steam, used to turn the shafts of generators. Running water of streams and waterfalls are used by hydroelectric generators and even radiation energy is used through nuclear power plants to produce the steam to push the shafts of the generators.

To see a miniature yet accurate functioning of the same in your own house, first construct the model of a town. Now use your 6-volt lantern battery to prepare a power plant. With the hookup wire, connect three hobby lamp sockets into your wiring.

Now prepare a T by sticking the ice-cream sticks together, so that they look like telephone poles. Fix these poles to a base with the help of the modeling clay, so that they can stand up on their own without any support. Fix the wires in such a way, so that they can go on from the top of it.

Now attach lamps to the model houses that you have. With the telephone posts and houses, you now have a miniature city. The telephone wires will connect the wires from the batteries to the lamps that are fixed to the houses in your city. Energy is changed, each time it moves from your generator to these lamps and thereby illuminates them.

Electric Supply

Thick cables carry electric current from power stations. Some of these cables are below the ground. Pylons or metal pillars are erected to support these cables when they are to be carried overhead. A system of cables and pylons link all the power stations in the country to a big network known as the grid. The picture below shows how the network carries electricity to your town. The cables carry plenty of electric power. For power to be safely used it has to be decreased or “transformed” at substations. Demand for power may vary from place to place and this is why the network allows it to be diverted from areas of low demand to areas with a higher demand. If the electric supply fails from one power station, it is sent along the same cables in the grid, from another power station. Thus the electric power supply remains un-interrupted in that area.
