There are only about 25 good locations for tidal power plants in the world. Old Faithful Geyser is a perfect example of this. Water and steam sprays from a hole in the ground where water is heated to such a point that it boils and turns to steam. Holes can be drilled in rocks to release this energy. This is released by splitting atoms by a process called fission which produces heat energy and electricity.
Nuclear energy has a very high cost and can be very economical to look for other alternatives.
This week we will be working in groups to research these different kinds of alternative energy sources. You will be responsible for making a poster to explain a particular alternative and write a report to give information on that source. Library books, pictures, diagrams, encyclopedias are available for you to use. We will report back as a group in three days to share with the others. I will help you with your reports and experiments.
