Resumen de Keychain Ziplines: a Practical Way to Study Velocity in the Calculus Classroom

Lisa Driskell, Audrey Malagon

• Using materials that are easy to procure, students create a zipline for a weighted keychain. They measure distances and times to calculate average velocities and explore the idea of instantaneous velocity. This inquiry-based calculus activity has been tested as a first day activity in classrooms at a variety of institutions and has received positive student and instructor feedback.
