Fun art project with the kids! Easy abstract painting that anyone can do! Just blob the paint on the canvas in random spots and blend! (would be interesting how students could make different pictures w/ the same colors and same blob positions)
Trace the shadow of your sculpture - foil figure or another object with a clearly identifiable shape. Ask, "If I hold the light here, will the shadow move?" Explore how the shadow elongates and shortens as the light is moved.
