Gears and Proportions
Students explore gears. In this simple machines and ratio instructional activity, students view a video clip in which front and rear bicycle gears are explained. From a set of gear combinations and gear ratios, students identify high...
Curated OER
Robot Gears
Students build simple gear trains and record data to discover how to compute gear ratios. They investigate the definition of torque and how torque can be increased or decreased in a gear train.
