The complicated mechanical devices we use daily have their origins in the simple machines whose principals we will explore together. A simple machine has no energy of its own and cannot do work by itself. Hammers, screws, and knives are classic examples of simple machines we use every day. But how exactly do they work most efficiently? These classes will combine Joy Hakim's text “The Story of Science: Aristotle Leads the Way” with an additional study of the ancient study of work and simple machines. Students should be prepared to use measuring and graphing skills to perform experiments and see for themselves how clever the designs of these simple machines actually are.
These classes will be held at the Crystal Lake Park District's Rotary Building on Thursdays from 1-2:30.
