Students research simple machines and other mechanisms as they learn about and make Rube Goldberg machines. Working in teams, students utilize the engineering design process to design and build their own Rube Goldberg devices with 10 separate steps, including at least six simple machines. In addition to the use of readily available classroom craft supplies, 3D printers may be used (if available) to design and print one or more device mechanisms. Students love this open-ended, team-building project with great potential for creativity and humor.
