“A Rube Goldberg machine is a contraption, invention, device or apparatus that is deliberately over-engineered or overdone to perform a very simple task in a very complicated fashion, usually including a chain reaction. The expression is named after American cartoonist and inventor Rube Goldberg (1883–1970). Over the years, the expression has expanded to mean any confusing or complicated system. Wikipedia The Physical Science Classes had the challenge of developing Rube Goldberg inventions to see how physics works. They were given certain elements they were to include; pulleys, levers, water, weights, angles. They were judged by a faculty panel on creativity, success, preparedness. All groups were definitely creative. Group 1 – Candy Land. Their contraption was decorated to look like a candy machine, and ultimately, present a cupcake and release confetti. Group 2 – It’s a Party. This group had everything from noise poppers, to balloons popping, to getting scissors to cut a string to release beads. Group 3 – Wedding Bells. Included in this project was getting a ring placed on a finger and having a ball carrom through a maze to drop on a computer to get it to start playing the Wedding March. Group 4 – It’s Christmas. Using a cell phone to start the mechanism, then ended, after going through many complicated maneuvers, getting a egg to drop into a boiling pot.
