This worksheet can be used for Children to create their own Kindness Project rocks. Keith Haring's work actually fits in perfect with this art lesson. Haring Believed that art should be for everybody and his cheerful brightly colored pop art makes for awesome happy rocks! Kids are encouraged to design 4 rock templates in Haring's style and then make their own rocks. I use acrylic Paint on the rocks and Encourage the kids to paint a base color in a thin layer a few times to make sure the color POPS.
