Background: For centuries windmills have been used to do work for us such as grinding flour or pumping water out of rivers. More recently windmills have been developed to use the power of the wind to generate electricity.

Challenge: To make wind power work for you!

Task: To Design and build and windmill/wind turbine which can raise five 1p pieces 50cm above the ground just using wind power.

Example:  

Use a hair dryer to provide your ‘wind’

You will need to think about…	Suggestions for Equipment:
Shape of the blades Size of blades Thickness of blades Number of blades How the shaft is attached to the table	✓ Scrap card✓ Sellotape ✓ Masking tape (optional) ✓ Pencils	✓ Scissors✓ String ✓ Paper/ plastic cup ✓ Hair dryer ✓ Five 1p pieces

Extra Challenge

Can you make your windmill using scrap material, rather than buying anything new and making it cost effective by;

• Reducing waste to a minimum (card, sellotape, string)
• Using something other than a hair dryer to provide the wind power?

Top Tips

• Use the TASC Wheel to help organise your thoughts and work.

• Plan out your ideas and present them showing all the stages of your work. You could use photos, words, drawing or a mixture of all 3.
