Colour Spinners!!

We have been looking at colour wheels. First we divided a circle into seven equal segments. We then coloured the segments in the order of the raimbow.

 

To spin the wheel quickly, we made a lego machine using cogs and gears.

 

When we spin the wheel the colours mix to make white.

 

(the camera is quicker than our eye so it still looks coloured on this picture)
