Measure Windspeed

As part of the GreenWave Project we usually measure the windspeed. This year the GreenWave project is not running but we are still going to go ahead with the project. Check out instructions for how to make an anemometer by clicking on the image below.

After making the anemometers, we took them to the yard and tested them out. There was a big difference on the number of rotations (360 degrees = 1 full circumference = 1 full rotation that each anemometer completed.

1. Full Rotation is 360 degrees

2. A right angle is 90 degrees

3. A straight line is 180 degrees (think of hitting the Bulls Eye in darts)
