Conductivity is crucial to our livesРfrom light bulbs to cellphones, we use it every day. But what allows materials to conduct electricity? Are all materials conductive to the same degree? In this activity, we focus on what makes materials conductive (going into a small amount of band theory) and how we classify different materials based on their ability to transport electrons. The lab focuses on circuits, using conductive ink pens from Circuit Scribe , started right here at University of Illinois in the Materials Science department!

Facilities needed: Classroom

Keywords: conductivity, electrons, band theory, circuits, resistance, insulator, semi conductor
