A robust knowledge of physics entails deeply understanding electricity concepts such as conductivity and resistance. Understanding how circuits work is also critical for ensuring the safe use of electrical technology such as car batteries and downed powerlines. Curricular materials covering these content ideas are readily available for teachers. However, these materials rarely promote the use of research-based practices to effectively scaffold from documented authentic historical episodes of physics research to physics and the nature of science (NOS) concepts. Such practices that invoke a conceptual change approach are a crucial component of inquiry experiences that deepen students' understanding of science concepts and the NOS. The highly contextualized inquiry activity focused on Georg Ohm and electrical resistance profiled here supports teachers' use of historically accurate video vignettes of scientific developments in physics to teach Next Generation Science Standards (NGSS) based NOS and science concepts.
