PocketLab Voyager/Wonder Gears: An Experiment on Gear Ratios and Angular Velocity

Submitted by Rich on Mon, 03/12/2018 - 03:10

Gears date back many centuries and are extremely useful since they can change the direction imposed by a source of power, as well as torque and speed.  This lesson describes an experimental study of the relationship between gear ratio and angular velocity by using PocketLab Voyager and Wonder Gears.    Wonder Gears is listed for ages 3+, with this lesson heavily emphasizing the “+” part of the description—since this lesson is perfect for junior high students aged 12 through 14.  This is one of the many advantages of PocketLab as it allows studying science principles quantitatively with toys initially designed strictly for creative play by very young children. The accompanying pdf file contains a detailed description of the experiment as well as a data table that can be duplicated for student use.
