What to do
1. Demonstrate how to dip the paintbrush into the water and squeeze two or three drops of
water into each color in the watercolor tray.
2. Have the children dip the small sponge into the water and wet the entire surface of their paper.
3. Before the water dries, tell the children to dip their brush into a warm or cool color, coating it
4. When they are ready, have the children paint a rainbow arch on their paper. Repeat the process
with the other colors of the rainbow, blending them.
