This is a great project for students to get their hands dirty and experience authentic science and engineering! Students will build a Rube Goldberg machine as a culminating STEM project after their unit on Force, Motion and Energy. They need 6 steps, 3 different simple machines and 3 different types of energy. I'm always amazed at what they come up with! One time I had a student roast a chicken. Another student blew up a birthday cake! Enrichment extensions are included but rubrics and brainstorming sheets are additional.
