In this evidence-based paper, an activity is described where students develop and validate conceptual designs of a gear train mechanism composed of spur gears. The design and operation of motion and power transmission systems is an important topic of study for mechanical engineering students. This topic is usually most closely associated with the mechanical engineering profession and may be addressed in a first-year course by describing the need for such systems and investigating equations of simple systems. In the activity described in this paper, students analyze the system, search for components from a catalog, and validate their design by building 3D computer models and running kinematic simulations on CAD software. The activity was successfully administered to an introduction to mechanical engineering class of 221 students during the Spring semester of 2017. A discussion of the resources and personnel required (faculty and graduate teaching assistants) is also presented. The activity is considered simple to implement only requiring a computer station with installed CAD software offered by most engineering programs. Continuous improvements to the activity are made based on faculty observations as well as a survey administered to the students.
