Next Look at the following picture slides and check whether your diagrams were correct.

The energy in flowing water can be harnessed to produce electricity.

Rainwater flows down hills and into a river Rainwater flows down hills and into a river. It then builds up in a reservoir behind a dam.

The water is released through a channel in the dam and falls on to a turbine, causing it to turn.

The turbine is connected to a shaft which, as it turns, drives a generator.

The generator produces electricity.

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

Now … 4. Do exercise 3 on the worksheet: complete the gaps.
