Simple Machines Sub Plan (No Prep): Machine Hunt & Chain Design, Grades 5-8

A made-up workshop hides 12 simple machines, two of each of the six kinds, and every one is marked with a number but never a name. Students name each machine, say what it changes (the size of a force, its direction or the distance it moves), then design their own Rube Goldberg-style chain of at least four simple machines that ends by ringing a bell. They label a sketch and write one sentence per link.
