This website contains a series of peer instruction problems on heat and temperature, designed to be solved in a classroom setting. The problems are presented with a qualitative question (usually multiple choice) that is carefully constructed to engage student difficulties with fundamental concepts.  Students consider the problem individually and contribute their answers using personal response systems (clickers).  Students then confer with their cooperative groups and vote again on the correct response. Topics covered include heat lost to friction, mixing liquids of different temperatures, and thermal energy.

This problem set is part of the Physics Suite collection, containing sample problems, peer instruction problems, and alternative homework sets.  See Related Materials on this page for a link to the author's free online book that explains the principles and pedagogy behind The Physics Suite and provides in-depth instructions for the physics teacher.
