Use this set of 4 demonstrations to introduce or to review the concepts of thermodynamics. Students observe and interpret demos illustrating the concepts of heat sinks, extreme endothermic reactions, and exothermic reactions resulting in crystallization. Data analysis and assessment questions help prepare students for the AP® Chemistry Exam. Materials are sufficient to perform the set of 4 demonstrations twice.

Introduce or review the concepts of thermodynamics in preparation for the AP® Chemistry Exam. Also suitable for general chemistry or freshman chemistry, this kit includes 4 demonstrations:

• The Burning Dollar Bill—Illustrates how the high specific heat capacity of water makes it a natural heat sink.
• Boiling Water in a Paper Cup—Gives yet another dramatic example of a water heat sink.
• Frozen Beaker—An extreme endothermic reaction causes a beaker to freeze tightly to a meterstick.
• Sodium Acetate Stalagmite—Helps explain the exothermic reaction that portable hand warmers utilize.

Carolina Chemonstrations® for Use with AP® Chemistry kits help students understand the particle level interactions that result in dramatic observed phenomena. Multiple demonstrations in each kit give students a framework for understanding AP® Chemistry concepts and help students move from the big picture to hard science. Students demonstrate their grasp of the concepts underlying the demo through a particle level explanation, apply their knowledge to analyze the data presented, and think critically about the topics by answering assessment questions. Materials in each kit are sufficient to perform each set of demos at least twice.
