Today we talked about simple machines, where they are found and the different types of machines. While some students didn’t enjoy the less hands on lesson they did enjoy the demonstration of the Class 2 Lever. Yuan in particular seems to have a very good grasp on mechanical principles thus far. Next week we will be talking about combinations of simple machines so please make sure they review the three types of levers, the screw, ramp, and the wedge.
