Colour Changing

Room 12 had done a science experiment about changing colors. The changing of the color involved a disc, three different colours which is red, blue and green. The first thing was use a circle based to help you guide and draw the circles, you have to draw three so two can be glued together and one can be on its own. Once your circles have been drawn we had to colour them in, after that we had to measure the dots that the piece of wool is meant to go threw, and it had to be two centimeters away from each other.
We had to do our dots then cut out the circles and thread the wool threw the two holes. We either had to spin it clock wise or anti clock wise.
