A Rube Goldberg machine is a creation named after American cartoonist Rube Goldberg. It is a machine intentionally designed to perform a simple task in an indirect and overly complicated way. Usually, these machines consist of a series of simple unrelated devices; the action of each triggers the initiation of the next, eventually resulting in achieving a stated goal. They are a brilliant way to explore forces, such as friction or gravity, and levers. Attached is a photograph of one and below are some links to YouTube videos of brilliant Rube Goldberg machines. They take hours and hours to perfect, the Honda advert 'Cog' (YouTube link below) for example took 606 takes to get a perfect run.

It must have a super simple mission, for example carrying a ball across the room or down the stairs, and it must be really over the top! Lego is a perfect tool for this job, as are things like cut toilet roll tubes, marble runs and folded paper, so you might want to raid the cupboards! Use the attached format to help you to plan and design your machine before you construct it. Share your difficulties and successes so that other children in the class can have a helping hand with their designs. Finally, record your efforts and share them on Seesaw. Good luck!
