Tongland Power Station generates hydroelectricity from the power of the River Dee. A simple demonstration with plastic bottles is used to explain how electricity is generated. Water from the River Dee is collected into a reservoir. This is then released through a pipe which channels it towards a turbine. The moving water turns the turbine, which generates the electricity. After this the water continues its flow down the Dee towards the sea. Tongland is one of six power stations on this river system. It generates enough electricity to light up 18,000 homes.

Pupils could be shown a range of photographs which depict power stations in a negative way. They can be asked to annotate their ideas onto photocopied pictures of a power station in a certain coloured pen. Then pupils could share their thinking with the rest of the class. After some discussion the teacher could present a research question to the class such as: "Why do we need power stations?" Pupils can then be shown the clip and once it has concluded, the teacher can lead a discussion on what power stations provide for us. Discussion can be around more positive thinking, for example electricity which gives us TV, warmth, lights. Pupils can then record these ideas on their original pictures in a different coloured pen. Using different coloured ink to record their ideas allows pupils to see how they have considered two opposing ideas.
