We are participating in Greenwave project in which students all over Ireland track the arrival of Spring in the country. We used their directions to make our own anemometer. The cups of the anemometer rotate with the wind and so gives us an idea od the speed or force of the wind. The first day we used it the strong crosswinds damaged one of the arms so we had to rethink our design.

Humans have harnessed the power of the wind to do work for us. Sailors use sails to capture the power of the wind and get their yachts moving. Nowadays the power of the wind is being used to generate electricity and create energy to heat our homes. Wind is a source of renewable energy but unfortunately it isn’t always reliable. Can you think why?
In the 19th century an Irishman Admiral Sir Francis Beaufort created a standardised system for measuring the force of the wind. This system is known as the Beaufort scale. Click here to find a drawing of the Beauford scale
