This item is a research-based lesson plan on the topic of total internal reflection (TIR), designed for use in introductory physics classrooms. It is aligned with the Interactive Lecture pedagogic approach. The purpose of the lesson is to help students apply Snell's Law to discover circumstances under which the TIR phenomenon occurs. This resource was peer reviewed by the SERC Pedagogic team (Science Education Resource Center). **NOTE: This lesson requires use of a refraction tank, available at science supply companies for $80-100. This item is part of the SERC Pedagogic Library, a collaboration between SERC Pedagogic Service Project and ComPADRE. SEE RELATED ITEMS on this page for a link to the full collection.
