Creation of a Robust DIY Speaker Kit to Engage Middle School Students in Hands-On Magnetism Instruction

Speakers have become an integral part of our world, from AirPods to public service announcements. Middle and high school students may not realize that the headphones they use daily depend on a physics concept that is part of their science curriculum – i.e., magnetism. In this work, we designed a DIY speaker kit that aims to connect student school science lessons on magnetism with familiar technology. We optimized a design for these kits that makes the most of hands-on activities to build self-efficacy, with a robust design that simplifies implementation in a classroom setting. The kits use 3D printed parts and easily obtainable electronic components costing < $20 per kit, making this a cost effective and educational demonstration that can be brought to most classrooms. In this presentation, we will discuss the creation of the kit, implementation in classrooms in the Urbana, IL area, and the impact on the students who participated in this activity. We will also share the designs and accompanying educational materials that can be used by others to create these kits and implement this educational module.
