  1. We’re going to give you some ideas about how to make a wind turbine. It will generate electricity from ‘wind’ made by a fan! You could try using it outside in the real wind. Or I could blow on it!

  2. We made the tower for the wind turbine out of a large plastic bottle. The bottle is partly filled with gravel. Can you think why? A piece of thick cardboard has been taped on top to make a platform for the turbine head (or rotor) to sit on. I made sure the front edge sticks out further than the bottle so the blades can turn.

  3. Now we can tape the electric motor to the front of the tower. Make sure it sticks out over the front of the card, won’t you? But where are the blades?

  4. The electric motor is going to be the generator. It will produce a small amount of electricity. Look at what to do next to make the blades! You use corrugated plastic to make the blades, dowel to join the blades to the wooden hub and a black pulley wheel – and that makes a turbine. Brilliant!

  5. Not bad Superhero, for our first attempt! Cool. Now what happens?

  6. The turbine is just about ready to test. I’ve had to make a few adjustments but it’s fine now. Can you see how the crocodile clips fix on the back of the electric motor? That looks great!

  7. Do you know what this is, Superhero? Ooh, is it a TV controller? Let’s watch cartoons! No, it’s a digital voltmeter, for measuring electrical output.

  8. We’re ready to test our turbine in front of the fan. After that, we can try changing the shapes of our blades and tilting them different ways to get the best reading on the voltmeter. What fun! Can I have a go? Please, please….

  9. All these different turbine blade shapes were made at school. Which do you think produced the most electricity? Why? Try bending the blades lengthways slightly and see what happens.

  10. Why not cover the plastic bottle with paper and decorate it? You could make it look like a real wind turbine tower or like a more colourful version! Can you think of a slogan to go with your wind turbine? Like ‘Winderful, Wonderful Wind Power’! This PowerPoint is based on work by Ian Mitchell, The Green Egg Company, developed & edited by Amie Andrews for TLCP and Vicky Darrell & Ali Ross, Sundog Energy.
