Unit 1 dives into simple machines, gears, and sprockets and chains. In each of these, you'll be learning the basics of what the functions of these simple machines are, where they can be found, and why understanding the math of these simple machines is important as an engineer! The unit will wrap up with a unit test and a compound machine project, where you'll be using multiple simple machines/gears/sprocket and chains to build a machine that works with each other to perform a specific function.
