Simple Machines

Simple machines help people do work. "Work" has a specific definition in physics, but a basic way to think about it is that work is making things move. For early learners, we provide opportunities for them to experience the ways that simple machines make moving things seem easier. In these resources, Sid introduces the simple machines of wheels, levers, inclined planes, and pulleys. Children are provided with opportunities to engage in scientific thinking and problem solving using these new tools.
