Moving air (wind) can turn the blades of windmills or turbines.
Windmills have been used for many years to help us do work like pumping water or grinding wheat for flour.
Wind turbines are now used to generate electricity.
The wind is a renewable energy source as there will always be wind.

Children may think that windmills and wind turbines create wind when the sails or blades spin.

Teaching slide explain that windmills and wind turbines harness the energy of the wind to do work for us or to generate electricity.

Wind turbine - A wind turbine is a device that is turned by the wind to generate electricity.
Energy source - Energy sources can be used to provide heat, light, or power.
Pump - A water pump is a piece of equipment that is used to move water from one place to another.
Generate - To generate electricity is to produce or make it.
Electricity - Electricity is needed for lighting, heating and making machines and appliances work.
