Rube Goldberg's Professor Butts and the Self-Operating Napkin (1931)
The intermediate grades used National Kid Inventors Day, January 17th, as a jumping off point to talk about the process of inventing, inventions that have changed our world, and the physics of simple machines, gravity and other physics principles. (Trivia fact: Physics is Mrs. Kovacic's favorite science.) We then learned about a man who developed very complex machines to accomplish simple tasks: Rube Goldberg. See the links below for a news story about Rube and the contest his family foundation continues as well as a great example of a music video that features a Rube Goldberg machine.
