Energy From The Wind

This week at Science Club we were learning about wind. We found out that wind is caused when hot air rises and cooler air moves in to take its place.

We made whirling snakes.
When you hold them over heat they spin clockwise.
When you hold them over cold they spin anti-clockwise.
The hotter or colder it is below them the more they spin.

We also had a go at making windmills. This was quite tricky but Bradley managed to make his work well. When the windmill turned it pulled up the load (blutac) at the back.


Windmills can be used to generate electricity. These types of windmills are called wind turbines. This way of generating electricity is a good one because wind energy is renewable and wont run out.
