As more paint was added and the marble was moved around the lid, the colours began to mix together to form secondary shades.
So in addition to the STEAM components, colour mixing was also being explored by the children. There was also some interesting discussion about the kind of lines the marble 'wrote' including straight, curvy and zigzag.
Children also had to exercise control as the marble could easily fall off the lid if they weren't careful and deliberate with their actions.
Even with a lot of paint on the lid the children were able to manipulate the marble by using a very strong magnet.
Look at these lovely shades of new colours!
Once the child had finished exploring, we encouraged him or her to make a print of the art by placing a large piece of paper on top of the paint...
...and lifting it off!
