I recently checked Mouse Paint by Ellen Stoll Walsh out of the library. It's a simple and fun picture book about three mice who find some paint and learn about mixing colors.
The red mouse stepped into a yellow puddle and did a little dance. His red feet stirred the yellow puddle until...
'Look,' he cried. 'Red feet in a yellow puddle make orange!'
The illustrations are made with paper collage and are bold and effective. Maia and I have both been enjoying this book. I'd like to try some color mixing with Maia soon. Of course she mixes colors on paper (and in the paint bowls) when she's painting, but at this point the haphazard color mixing usually ends up a muddy brown. I'm thinking of a more specific color mixing project, perhaps with just two colors at a time.
Perhaps we'll try an activity like Gwyn's at My Kids Art. She put yellow and red paint into a plastic bag and let her boys squish it around until it made orange. She said they had lots of fun with it!
I've also read about filling an ice cube tray with water and giving your child a dropper and some food coloring to experiment with color mixing.
Any other color mixing activity suggestions?
