Pendulum Paintings

Pendulum paintings were created by my 8th grade art students. We discussed the forces of gravity and momentum while using a pendulum to paint on canvas. Students painted the background of the canvas first and then selected colors to be used inside the pendulum. A modified water bottle was used to dispense paint as the pendulum moved slowly across the surface. Students tried various techniques, made predictions, and told me that this was "satisfying" to watch.
