Discusses the difficulty of explaining the concept of entropy, and provides exercises, experiments, and discussions concerning entropy. (MLH)

Describes how to construct an isothermal calorimeter and lists typical results of a displacement reaction using zinc. (LS)

Contains contributed suggestions for laboratory equipment, chemistry activities, and explanations of chemical reactions. (CP)

Described is the use of a spreadsheet to model dynamic phenomena using numerical iterative methods. Uses the discharge of a capacitor, simple and damped harmonic motion, and the flow of heat along a bar as examples. (Author/CW)

Discussed is the idea that energy is the cause of change. This idea, going back to early cognitive development, means that the teaching of energy needs to confront how, thermodynamically, people can perform actions. The change in energy caused by differences is emphasized. (KR)

Shows that the second law of thermodynamics is in the common experience of many people and if taught first, before the law of conservation, can result in fewer misconceptions among pupils. Stresses the use of common experiences in teaching. (CW)
