MD loved doing this color mixing activity, he loves anything with water and color. Seeing the colors change as he mixed them was very exciting for him. He had difficulty using the dropper though as he has not quite yet figured out the squeeze and release. So of course I helped him out.
One reason I like the Montessori philosophy so much is the emphasis on having children pick up and clean up after themselves and caring for their environment. We have been making a lot of progress in this area lately.
