Windmill Challenge

 First we introduced the idea of windmills and wind power by looking at images of all kinds of windmills, from dutch windmills with pumps to wind farms.

 Then we got crafty and made simple paper windmills to demonstrate wind direction & power

We then moved on to making the bespoke bottle windmill design we had created using a plastic bottle, paper and clear acetate, a kebab stick, cork, thread and a button! 

 These bottle windmills pumped the button up and down on the thread and depending on the wind direction the button went either up or down. We now understood about wind power and pumping.
