Simple Machines


We have been using Lego to learn about some of the simple machines. We have experimented with models to find out how pulleys, levers, gears and wheels and axles work. Gears and pulleys can be followers and drivers. We learnt that with gears the follower goes in the opposite direction to the followers, except if it has a gear (an idler) in between.
