Abstract
Students at the high school level are guided by instruction into discovering a scientific law. The process utilizes laboratory activities centered around the scientific method. Students investigate heat transfer in various metals using calorimetry. The activities include designing experiments, collecting data, using graphical analysis, and hypothesizing. This culminates in the discovery of the Law of Dulong and Petit. In all, approximately ten 50-minute class periods are used.

The Heat Is On: An Inquiry-Based Investigation for Specific Heat
Deborah G. HerringtonJournal of Chemical Education2011 88 (11), 1558-1561The Heat Is On: An Inquiry-Based Investigation for Specific Heat
Deborah G. HerringtonJournal of Chemical Education2011 88 (11), 1558-1561A substantial number of upper-level science students and practicing physical science teachers demonstrate confusion about thermal equilibrium, heat transfer, heat capacity, and specific heat capacity. The traditional method of instruction, which involves ...

Mary Laing and Michael LaingJournal of Chemical Education2006 83 (10), 1499Dulong and Petit's law played an important role in the development of the periodic table as Mendeleyeff used this method in 1870 to correct the atomic weights of indium, cerium, and uranium that were wrong in the table of 1869. The discontinuous variation ...
