Keeping It Simple
Keeping It Simple


In science, third graders recently studied simple machines, which include the lever, inclined plane, screw, wedge, pulley, and wheel and axle. As the culminating activity for this unit, each student was tasked with constructing a model of a labor-saving device featuring two or more simple machines, which were presented to parents, faculty, and staff at an expo on December 20. Take a look at some of the prototypes.
