Engineering: How the Six Simple Machines Support the World

In Engineering: How the Six Simple Machines Support the World, young engineers ages 12 to 15 learn how modern engineering is based on the six simple machines that humans have been using for thousands of years. The screw, pulley, wedge, wheel and axle, inclined plane, and lever are used to build roads, skyscrapers, bridges, engines, and even other tools. Hands-on STEM activities encourage use of the engineering design process as kids brainstorm and build practical prototypes and explore how we might employ simple machines in the future.
