Rube Goldberg Machines

Over the past semester everyone in year 5 has been building Rube Goldberg Machines. A Rube Goldberg Machine is a very complicated contraption to complete a simple task, like turning on a light or cooking toast ours flicked a lolly into your hand. Building our Rube Goldberg Machines took lots of time and hard work so today we had a chance to show them off. When we showed off our machine we explained who Rube Goldberg was and how our machine worked and then tried it out, our machine only worked once but luckily lots of people were watching. The restrictions to building our machines were, it had to have a number of simple machines and elements equal to the number of people in the group and it had to be confined in the size of one large box. Our group had four people so that meant four elements and four simple machines. Our simple machines were, two inclined planes, three levers, a wedge and a fulcrum. From building our Rube Goldberg Machines I learnt that if        something doesn’t work the first time you should keep on trying. IMG_4652
