Resonant Pendulums: An Inquiry-Based Physics Lab

In this paper we describe a new resonant pendulum inquiry intended for upper-level physical science majors. This activity was originally taught as a part of the Workshop for Engineering and Science Transfer Students in the Physical Sciences (PhysWEST) in 2008. This activity is designed to help students learn process skills necessary for successful scientific research while simultaneously learning about natural frequencies and resonance. One main goal of this activity is to demonstrate how fundamental physical concepts can be used to explain a wide range of phenomena relevant to students from diverse backgrounds and interested in a broad range of degree programs. This paper presents a description of our goals and the key features of the activity design.
