Rube Goldberg is an overly complex contraption designed to accomplish a simple task. The best RGMs emulate their namesake by using a variety of everyday items in a whimsical way to create a series of chain‐reaction steps to accomplish a simple task. In the contest, exhibitors not only employ physics and engineering, but humor and storytelling, to create their RGMs. This activity is a team event of at least 3 and no more than 10 members.
Requirements: ‐ Teams of at least 3. Minimum of 10 steps ‐Machine must operate in 2 minutes or less ‐ Exhibit physical size limited to 6 feet x 6 feet x 6 feet ‐ Explain one thing/step on the machine that they use science content and skills to help solve a problem/challenge
‐Create a blog (webpage) to show the Rube Goldberg Machine online
‐RG machine itself
‐Display, binder, poster illustrating the process of the doing the activity/project.
Teams will be able to explain their Rube Goldberg machine to the judge and demonstrate their machine as well. These will be scheduled throughout Friday of the fair in 30 minute intervals and will be set up to avoid any other judging conflicts that team members may have. The second phase of the judging will consist of a showcase public event (Friday Evening) where each team will demonstrate their machine. Both events are required and team representatives should be present for both events.
