Making Windmills in the Secret Garden

As part of the science - colour mixing theme at school this week, the children made their own colourful pinwheels (or windmills). 
To make you will need...
a square of paper (or thin card)
colouring pencils or crayons
scissors
hole punch
paper fastener (or split pin)
straw (or stick) 
We started with a square of paper and coloured each section a different primary colour (red, yellow, blue) and also a secondary colour (green).
We then carefully cut towards the centre from each corner but stopping short of the middle of the square.  
then we hole punched a hole in each corner and a also a hole in the middle.  We then folded each each section towards the centre and fastened with a split pin (paper fastener).  we then attached a straw (or stick).  Then held them in the wind and watched them spin.
Perhaps you could have a go at making your own colourful windmill too.
