This booklet can be handed out to your students to guide them through an engineering design project of building their own Rube Goldberg Machine. I start the project by explaining what a Rube Goldberg Machine is and show examples of them online. Honda Sports Center, and Myth Busters all have very complicated (yet impressive) machines while you can find simple ones done by kids on You Tube. This booklet walks them through the planning, design, building, and reflection process. This project is designed for students to work in groups and talk about energy transfers, simple machines, and problem solving in their reflection. There is a section for students to use Tinkercad to design a piece for the Rube Goldberg machine that can be printed on a 3D printer. If you will not be using a 3D printer during the project you can delete the parts referring to Tinkercad. There are rubrics to grade group work for each part of the project and a page for each group member to use to grade each other.
