Solving Problems With Simple Machines is a compilation of a few videos from a few years back. The segments of the video explain what simple machines are and give examples of using simple machines like levers, pulleys, axles, and wheels.
Applications for Education
Before showing the video to students I would ask them to answer a question like, "what is a machine?" or "what do you think machines do?" Then after watching the video I'd follow-up with a question along the lines of, "can you think of other examples of simple machines?" before moving on to having students build simple machines like those found in Exploratorium's Science Snacks.
