Entropy and the Shelf Model: A Quantum Physical Approach to a Physical Property Arnd H. Jungermann
A quantum physical approach relying on energy quantization leads to three simple rules which are the key to understanding the physical property described by molar entropy values.

Synthesis of Aspirin: A General Chemistry Experiment John A. Olmsted III
An experiment is described that is suitable for the early portion of the laboratory in a general chemistry course and integrates organic examples. It is the two-step synthesis of aspirin starting from oil of wintergreen. The mechanism for this synthesis provides examples of three major classes of chemical reactions: hydrolysis, condensation, and proton transfer.

Synthesis of Exotic Soaps in the Chemistry Laboratory Otto Phanstiel IV, Eric Dueno, and Queenie Xianghong Wang
A variety of different triglyceride sources ranging from Vietnamese garlic oil to a local restaurant's grill sludge were saponified to generate a series of exotic soaps. Students did not quantify their results, but described their products in terms of color, texture and odor.

Does Copper Metal React with Acetic Acid? Stephen DeMeo
Starting with a discrepant event and led through a series of experiments, students of an introductory chemistry course investigate if copper metal reacts with acetic acid. Finding that oxygen from the air plays an important role in the reaction of these substances, students ultimately realize that the conditions under which two reactants interact are important in determining the type of products that are made.

An Organoleptic Laboratory Experiment John M. Risley
Compounds in ten different classes of organic molecules that are used in the fragrance and food industry are provided to students. Students whiff the vapors of each compound and describe the organoleptic properties using a set of terms utilized in the fragrance and food industry. A set of questions guides students to an understanding of the relationship between structure of molecules and smell.
