The children noticed the paint colors, but their focus quickly shifted to the process of putting the paint on the filters with the droppers, and the mechanism of the droppers themselves.
Can you use one dropper to put paint in another?
Can you fill all the droppers at the same time?
What would happen if you put a new filter on top of one that's already full of paint?
This art activity wasn't all art. But this science activity wasn't all science. This was an exploration of color, of water, of texture, of material. The activity might not have been about creating a product, but the product of color and liquid interacting with solid and diffusion was a product. The art was in the process: the kinetic, changing, evolving process. The art was science, and the science was art.
