Why Choose us?

Points to consider

You will need to show the company name and logo.

Identify the advantages of your chosen generators.

Suggest how you might

overcome any disadvantages.

Use the materials provided to show where you would locate the energy sources and the factory, and the area likely to be

taken up by each.

1. The Generation Gap

The seas at the North coast of the island are very shallow

Sunshine is very good : average

temperature is 18°C

Rainfall averages 5cm per month

Tides: Strong powerful currents

experienced on the South of the island

Seas to the south

of the island

have vast oil

deposits

There are coal deposits to the

North East of the island

Wind is constant

The river cuts through deep wide valleys as it makes its way to the sea in the West

There are sheltered harbours and very

rich fishing grounds in the South

There is one forest in the South East, which has been turned into a bird

reserve, and feeding grounds.

Most of the inhabitants on the island are

farmers

Factory requirements : 3.5MW

1. The Generation Gap: About the Island

Outline the area taken up by each type of generator.

Make ‘flag’ markers to show on the map where you plan

to put the generators.

Calculate the power output expected from your system and enter the totals in the

chart provided.

1. The Generation Gap

• Tidal : 0.5MW is maximum allowed if the generator is not to affect local fish populations.

• Solar: Covering the whole roof of the factory with solar panels will generate 0.5 MW power.

• Wind: A 1MW wind farm will be allowed on site.• Geothermal: is not available at this location.• Hydro: 1MW can be produced for the factory at this location.• Biomass: is not available at this location.• Wave : 0.5MW can be produced per 100m coastline (West

Coast sites).• Fossil Fuels : The Government Grant Scheme does not permit

the use of fossil fuels. • The Factory will require at least 3.5 MW electricity, preferably

involving a maximum of 3 types of renewable energy sources.

1. The Generation Gap

Solar• Solar energy is free.• A solar power station does not work at night.• It is expensive to build solar power stations.• Lots of solar cells are needed to produce the same amount

of electricity as fossil fuels.• Solar energy produces no waste or pollution.• Solar power stations are unreliable unless you live in a

sunny place.• Enough energy reaches earth from the sun, every minute, to

meet our demands for a whole year.

1. The Generation Gap : Pros and Cons

Wind• Wind turbines are noisy.• The land beneath a wind farm can still be used for farming.• Wind farms produce no waste or gases.• Wind farms can affect television reception nearby.• Lots of wind turbines are needed to produce the same

amount of electricity as fossil fuels.• Wind farms can be tourist attractions.• Wind is free, no need to buy fuel.• Wind farms are best next to the coast. Buying land at the

coast is expensive.• Wind turbines can spoil the scenery.

1. The Generation Gap : Pros and Cons

Wave• Waves are a source of renewable energy.• Some designs of wave turbine are noisy.• You need a suitable site where the waves are strong.• The wave turbine produces no pollution.• A wave turbine has to be anchored to the sea bed to

withstand the roughest seas.• Wave turbines can ruin the scenery.• Wave turbines do not produce a lot of electricity compared to

fossil fuels.

1. The Generation Gap : Pros and Cons

Tidal (i) Barrages• They don’t need fuel.• There are very few suitable sites.• They are very reliable.• They only produce electricity about 10

hours a day, when the tide is moving in or out.

• They produce no pollution or other waste.

• Very expensive to build.• Once the dam or barrage is built, the

energy is free.• They can affect the environment over a

large area – feeding birds, marine life.

(ii) Offshore Turbines• They are like

underwater wind farms.• They are much easier to

build.• They don’t affect the

environment in the way a tidal barrage would.

• There are many more suitable sites.

1. The Generation Gap : Pros and Cons

Hydroelectric• Hydroelectric energy is clean and produces no pollution.• Dams are very expensive to build.• Once the dam is built, the energy is virtually free.• Water can be stored above the dam ready to cope with peak

demands.• Finding a suitable site is difficult.• Building a large dam can flood a large area causing problems

for animals and people.• It doesn’t produce a lot of electricity when compared with

fossil fuels.

1. The Generation Gap : Pros and Cons

Fossil Fuels• They were made millions of years ago and are NON

Renewable.• Coal can be easily transported to power stations.• Oil and gas can be piped to the power station.• Burning coal causes acid rain.• Mining can destroy the landscape.• Transporting oil on ships can cause sea pollution.• Burning fossil fuels produce gases which cause the

‘Greenhouse Effect’.• Very large amounts of energy are produced by burning fossil

fuels.

2. Beat the Goalie

You will be provided with • A kit to make a launch pad for a Ping Pong ball• An empty Pizza box• Bendy straws• Cocktail sticks or skewers• Coloured card• Sticky tape• Pens and scissors

Your task, as a team, is to transform these materials into a simple ‘Beat the Goalie’ game

Making the Launcher

The snap-on part of the battery holder should be used as an on-off switch

Don’t wear out the battery too soon!

The two motors should be connected so that they spin in opposite directions

Clockwise on right, anticlockwise on left

Teams may investigate the effect of changing the angle of launch of the ball

2. Beat the Goalie

Making the Game

The completed launcher should be taped on to the front edge of the pizza box.

It should fold out when the box is opened

The goal should be constructed at the other end of the box, which is opened out flat.

A goalkeeper should be designed, using the card and straws, to be operated by a player behind the goal

The size of the goals is up to you, but the goals and goalie should fit in the box when not in use

Safety glasses should be worn by those closest to the game

3. Mars Express

• Imagine you are working for a toy/games manufacturer who wishes to capitalise on the recent public interest in the NASA and the European Missions to Mars.

• Your task is to design and make a children’s board game of an

Expedition to Mars, using available materials.

• The final product must fit neatly into the box provided.

4. Electrical Quiz Board

Choose your own topic for the quiz and decorate the quiz board to match your theme.

Electrical quiz board  An electrical Quiz board –lights up or buzzes if answered correctly Pupils choose their own theme for the quiz and design the board to give both the questions and the answers.

 Paper fasteners placed beside each statement allow you to place a connecting wire on the back of the quiz joining each question to the correct answer.

The quiz can be pasted on to the top of the pizza box and the wires fed through the lid to connect with the battery

The battery should be housed inside the box and the bulb or buzzer mounted on the lid. The circuit is complete when a connection is made between a question and the correct answer.

(Buzzers need to be connected the right way round – red is positive, black is negative.)
