IGG INVESTIGATE and EXPLORE: Choice Challenge 16
Make a windmill and try it outdoors
- A sheet of white or coloured A4 paper for each Brownie
- Drawing pin
- Colouring pencils
Template in attached file
Windmills use wind energy to make electricity.
· Cut out a square template in attached filefrom the sheet of A4 card/paper
o Fold one corner of the paper until it meets the opposite edge, forming a triangle – make sure they are even
o Cut off the extra paper and unfold your perfect square
· Using the ruler draw a line joining diagonal corners – see template
· Cut along these lines from each corner for about 10cm
· Using your colouring pencils, colour in the template
· Pull the corners down to the centre point
· Stick a drawing pin through the centre of the paper, making sure it is also stuck through the 4 folded corners. This is the wheel of the windmill
· Now stick the pin of the wheel into the unsharpened end of your pencil
· Blow on the windmill or bring it outside and hold it up to the wind
The force of the wind turns the windmill around. On wind farms there are large windmills.
These windmills are similar to the one you made. The wind turns them and this is used to make electricity.
