Electricity

Now that you’ve learned about circuits, powering bulbs and motors, lets combine

this knowledge with saving the planet.

ElectricityElectricity is the most common form of energy we use at home and at school. It is a secondary energy source, which

means that we get it by converting other sources of energy, such as:

coal oil

natural gas

nuclear energy hydropower solar energy wind power

Some of these energy sources are not renewable , create pollution, and waste. Others provide energy that people haven’t discovered how to store. Which would you use? Why? What are the benefits

and the drawbacks?

You’re using Energy when…You drive to the store You wash your hands

You turn on a computer

Think of all the things you do from when you get up in the morning until you go to bed at night that require an outside source of energy. It’s a long list,

isn’t it?

Think about number of people there are all over the world and how much energy is being consumed. We all have to

find ways to conserve energy. What does that mean?Energy conservation means reducing unnecessary energy use and waste. Consuming less energy also reduces the amount of carbon dioxide and other pollutants released

into the atmosphere. To see some simple ways that people can conserve energy click on the link below.

Now it is your turn.

You and 3 other students are going to make your own brochure. It has to contain:

• energy-saving actions people can take • explains why saving energy is important.• list the pros and cons of one source of

alternative energy You will find all the links, clip art, and photos to use on the

computer desktop folder named Energy Brochure.
