This video is a tutorial science investigation that is aimed at a Stage 2 (Years 3/4) classroom.

On a windy day it is hard to keep your hat on! The power of the wind can even be strong enough to power large wind turbines to make electricity! In this experiment, find out how you can make your own instrument to measure the speed and power of the wind. How does it work?

The original idea is from Science Buddies and can be found here: http://www.sciencebuddies.org/science...

Hope you enjoy :)
