Craft project: Use red, blue and yellow cellophane to make a color wheel that teaches about combining the primary colors. Have your child see how many colors can be made by overlapping the cellophane layers. To see even more colors, the color wheel doubles as a spy glass that your child can look through to make the colors of things change.
