Facing the Music: How Original Was Borodin's Chemistry? Michael D. Gordin
A return to the original sources demonstrates that the evidence for Borodin's reputation as a great chemist, as opposed to a merely good one, is exaggerated.

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.

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.
