Windmills are machines that harness the power of the wind to produce electricity. It is alternative energy implemented to shift our main use of energy from non-renewable sources to renewable sources of energy. Windmills have long been used on farms to grind grain or pump water to generate enough power to meet the needs of a large number of people.

For student activity, paper cups and straws can be used to make a prototype of a windmill at home or in the classroom. Student will be going to design a windmill that can lift small items such as coins.
