Take a closeup look at different types of machines and how they are used. Your students will build two different types of simple machines; learn about the mechanical advantage of each; measure their work input and output; and determine how well each machine operates by calculating their efficiency. In the process, they’ll identify the primary factors that affect efficiency. Based upon their findings and newly gained knowledge of efficiency, the students will then be asked to design and test their own, more efficient simple machine.
