First … Do exercise 1 on the worksheet: label the diagram. 2. Talk in your group and discuss how wave power generates electricity.

Next Look at the following picture slides and check your answers to exercise 1.

The energy in waves can be harnessed to produce electricity.

As waves crash into a chamber on the seashore,

they drive air into a pipe on the top of a chamber

The pipe is fitted with a turbine which rotates as the air is forced past it.

As the waves leaves the chamber, air is sucked back down the pipe, keeping the turbine moving.

The turbine is connected to a shaft, which powers a generator to convert the energy into electricity.

Electricity is sent via pylons and cables to homes around the country.

Now … Do exercise 2 on the worksheet: match the two parts of each sentence. 5. Do exercise 3 on the worksheet: write sentences using the prompts.

Presentation (for classes working in groups only) 6. Give an oral commentary on the picture slides.
