This is a multi-step, multi-week Rube Goldberg Group Project that I did in 7th grade for many years, and it was ALWAYS super fun and a highlight of the year. It accompanies a Physics Unit on Forces, Simple Machines, and Energy, and is best to incorporate into a 4-6 week unit. I can easily be adapted for grades 6-12, varying the concepts of physics that are expected to be demonstrated.The goal is to design and engineer a Rube Goldberg machine and present it to peers, other classes, or even the
