We are investigating the weather.  We made a wind vane so that we can find out which direction the wind is coming from.  We had to read the instructions very carefully and cut and join the pieces so that it could still move in the wind.  Lots of terrific teamwork was needed as it was a bit fiddly!! We enjoyed testing them outside.  We used a compass to help us find out which way was North.

 

Have a look...
