The invention of machines has had a profound impact on human history. Machines, both simple and complex, have been used for many purposes, from making our lives easier to waging war. Students encounter many kinds of machines each day, including some that use motors.
The invention of machines has had a profound impact on human history. Machines, both simple and complex, have been used for many purposes, from making our lives easier to waging war. Students encounter many kinds of machines each day, including some that use motors. In Working with Motors and Simple Machines, students learn about 3 simple machines (inclined plane, pulley, and lever) and how these machines reduce the effort force needed to do work. Students also explore motors and how they function. Students are challenged to combine their knowledge of motors and machines to design a system that lifts a heavy load.
