Using Mathematical Models in Engineering and Science –Using Gears to Learn About Ratios and Proportions
by Kathy Hartley
In this lesson, students will explore the concepts of gear ratios and proportions. They will construct a working gear system and observe how the ratio between gears affects their motion. They will use proportional relationships to find the ratios between different gears in a system.
