PREP PHYSICS THE RUBE GOLDBERG CHALLENGE 2014 – 2015 This year at BELS saw the largest group of Prep-students yet, and with that came the proportionally increased level of excitement for the completion of some really great Physics Projects. The Rube Goldberg Machine challenge required some creative simple machines to be combined in an attempt to burst a balloon by using as many of these machines as possible, and in the longest possible time. The target time was set as 2 minutes, and there were actually a few students who were able to reach this time! The Rube Goldberg Machine challenge is a practical approach to introduce and enhance hands-on skills in a fun-filled way, while also allowing learning through investigation and trial-anderror. Different materials and practical tools are used during the construction of the projects, and for many students, this is the first “big project” that includes a problem-solving approach which requires creative thinking, an experimental design process, a practical construction process, a written report, and a verbal presentation. Creativity and variety of designs were some of the remarkable aspects of this year’s challenge, as was the use of different mechanisms and processes that were never used at BELS before. Besides the dominoes (simple lever) and inclined planes we also had candles burning through a rope like an ancient time delay mechanism, and water falling into a series of containers, which in turn activated different release mechanisms. Spirals and double-sided boards with multi-level and through-panel push-rods amazed all the observers and judges alike.
