Materials
Clean, damp sponge
Tempera paints (red, orange, yellow, green, blue, purple)
Large white construction paper
Directions
Place small amounts of tempera paint in the color order of the rainbow along the length of the damp sponge. Invert the sponge on the white paper that’s taped to the table. Invite your child to move the sponge across the paper. He’ll delight in what he has created – a beautiful rainbow! Repeat the process as long as your child is interested.
