One setup for many experiments: enabling versatile student-led investigations

Abstract

This article presents an experimental setup capable of conducting various experiments. The setup is used to accurately determine the acceleration due to gravity using either the pendulum or free fall experiment, as well as to allow students to conceive and conduct their own experiment. We discuss the design of the setup and the experiments conducted with it, highlighting the versatility and potential use for open inquiry. We include students’ perception on this particular experiment and how it led to an interesting and educational open inquiry.
