Simple Machines

Children are introduced to the concept and history of simple machines in this physical science worksheet. Kids learn how the idea of simple machines, which originated with Greek philosopher Archimedes, inspired the work of scientists like Galileo Galilei and artists like Leonardo da Vinci. Illustrations and a matching activity help students conceptualize what each of the six types of simple machines—wheel and axle, pulley, inclined plane, wedge, and screw—look like. Designed for a fourth grade science curriculum, this resource lends well to STEM inquiry.
