This web page provides a list of learning activities for Junior level Thermodynamics and Statistical Mechanics classes. Each activity includes a description and learning goals, guides for instructors, handouts or worksheets,  and reflections of instructors who have used the activity when available. Among the materials are simple labs, investigations of PV and TS diagrams, exploration of concepts in probability, and partial derivative in thermodynamics. Links to related mathematical concepts are also provided.

This material is part of the Paradigms in Physics project at Oregon State University. This work promotes the use of active student learning in upper division physics courses. Both learning materials and learning strategies are provided to help both students and instructors.
