If you’ve never done this project with your art students, it’s a great way to teach value. I think I’ll take it one step further next time, and make them “Impossible Pipes.”
For this project, the kids used a dark piece of construction paper and oil pastels.
They first drew out their pipes with a pencil and a ruler. Then, using a solid color, they colored the pipes. Finally, they added the white and black, keeping the light source coming from one location.
