I've been wanting to have students try this project for a while, but I only had donated hobby motors with an unreliable history. As luck would have it, a science teacher at the high school cleaned out a different cabinet doubling our access to working motors. We had old paper coffee cups, expiring markers, rubber bands, scissors, rulers, and paper lying about. The box you see on the table is what students use as a work tray. This helps keep tables clean and gives students a way to keep their supplies together should they need more time to complete a project.
I found a handout in PDF format and a link to a YouTube tutorial.

Tip for success: Have good tape ready! Old or stretchy tape will not work. I also had a handful of electrical tape for securing wires to the battery.
