Thermal Paper as a Polarity and Acidity Detector

Thermal paper such as that used for point of sale receipts typically functions by darkening when exposed to heat. The pigment system used in this paper also darkens when exposed to solvents of intermediate polarity and acids. This enables thermal paper to be used as an inexpensive sort of indicator paper for a variety of demonstrations.

A Manipulative Paper Tool for Teaching Organic Nomenclature: Part 3- Common Names of Major Classes of Organic Compounds

This is the third in a series of classroom activities using paper tools to teach organic nomenclature. This post covers the two common naming systems used for carboxylic acids and derivatives, and second for alcohols, thiols, ethers, amines, and ketones.

A Manipulative Paper Tool for Teaching Simple Organic Nomenclature: Part 2, IUPAC Naming of Major Classes of Organic Compounds

To help introduce students to organic nomenclature in a way that clearly summarizes the patterns that exist in the IUPAC system, a series of paper tools were developed. The paper tool in this activity can be used to introduce the IUPAC naming of major classes of organic compounds. These paper tools are easy to print and distribute to every student each semester.
