How This Project Works in Class

In under 3 hours, students learn how simple machines work, then use the Engineering Design Process to design, test, improve, and share their own Rube Goldberg machine.

  1. 1

    Intro to Rube Goldberg Machines

    The Hook · 10 min

    Students watch an entertaining Rube Goldberg machine in action, learn who Rube Goldberg was, and preview the challenge of building their own chain-reaction machine.

  2. 2

    Learn Simple Machines

    Simple Machines Bootcamp · 80 min

    Students explore all six simple machines — inclined plane, wheel and axle, lever, pulley, screw, and wedge — and learn how each one can help them build a Rube Goldberg machine in Qweebi.

    Design Your Rube Goldberg Machine

    Final EDP Challenge · 40 min

    Students use the Engineering Design Process to plan and build their first Rube Goldberg machine prototype that can feed a pet.

    Improve and Share Your Invention

    Reflection · 40 min

    Students refine their Rube Goldberg machines, then create and submit a show-and-tell video where they showcase their invention and explain the challenges they overcame.
