Today we used simple machines to learn how spreading a force over a distance can make it easier to move objects. We reviewed the six simple machines and how they work. The class then proceeded to explore levers, pulleys and a compound machine consisting of an incline plane and a pulley. We discussed how collecting a lot of data can mask some of the inaccuracies and irregularities that occur in elementary classrooms. Kelly shared literacy connections and how you can use literacy to initiate a an engineering project. In the afternoon we presented our group with an engineering challenge. They would have to design a Rube Goldberg device that incorporated three simple machines.
To wrap up our day, our docent Julie, took us on a tour of the 15th floor of Wilson Hall and of the Linac Accelerator.
