Unit 3 - Water Power!
Using Water to Turn on the Lights
Water is a very powerful resource. Did you know that water can be used to create electricity.
Read the following articles to find out about the different ways of generating electricity from water.
- BBC Weather Centre Climate Change [article]
- CBBC Newsround: Water Power [article]
- BBC GCSE Bitesize: Science: Generating Electricity [article]
- BBC News: How it works: Wave Power [article]
Choose one of the methods of generating electricity from water and create a fact file for the other pupils in your class. The fact file should describe how electricity is generated (using diagrams) and identify where you could get this sort of energy (at the coast, in hills or mountains, in the middle course of a river).
Now look at the following clips and articles and think about the advantages and disadvantages of getting electricity from water:
- BBC News: Tidal Energy System on Full Power [article]
- BBC Primary Focus: Green Power Teachers notes and worksheets [PDF]
Discuss these advantages and disadvantages with the rest of your class. Find out why water power is sometimes called ‘renewable energy’. Do you know about other types of energy sources that are not renewable?
