Making Usable, Quality Opaque or Transparent Soap Suzanne T. Mabrouk
First-year and organic chemistry students will learn the chemistry of soap by making some of the eleven described formulations, which produce usable, quality bars of soap. Opaque and transparent soaps are made in two and three hours, respectively. With an introduction to formulation chemistry, organic chemistry students can devise a formulation to synthesize their own opaque soap. Many of the formulations use commonly-available fats and oils, while some formulations incorporate specialty fats and oils for therapeutic purposes, for example, to relieve dry skin or itching.

Our Everyday Cup of Coffee: The Chemistry behind Its Magic Marino Petracco
Coffee beverages are so popular all over the world that there is hardly any need to describe them. But underlying this seemingly commonplace beverage there is a whole realm worth serious scientific study. The complexity of the raw seed matrix, made even more intricate when roasted, requires a deep understanding of its chemical nature. While coffee is not consumed for nutritional purposes, it is appreciated for its taste appeal along with its stimulating effects on mental and physical activity. The attention to quality is of paramount importance to both of these aspects to supply the customers with a pleasant and wholesome product.

We generalized the question into: Why does soap performance depend on the hardness of the water used? A sequence of experiments was carried out to compare the performance of soap in soft and hard water and to illustrate the water-softening action of EDTA and zeolites.

Measuring Viscoelastic Deformation with an Optical Mouse T. W. Ng
A simple demonstration of viscoelasticity can be carried out by attaching a weight to a polymer film and watching it extend over time. For accurate and quantifiable data on the deformation, an electronic displacement sensor should be incorporated. Most of such sensors are expensive. Here, an optical mouse was demonstrated to provide accurate data at low cost. The experiment was also devised in a manner to allow students to learn about viscoelastic deformation experientially.

Chocolate: A Marvelous Natural Product of Chemistry Ginger Tannenbaum
This article is a survey of chocolate from tree to table. After a brief introduction to the history of chocolate and how and where it is grown, the manufacturing process is examined, and the chemistry is explored. A bit of the jargon used in the industry is mentioned. Cocoa butter is a significant ingredient in chocolate, and an investigation of it introduces triglycerides, fatty acids, polymorphic behavior, and molecular packing of the fats in chocolate and how they affect the tempering process. There is a brief discussion of chocolate's non-Newtonian behavior and the resulting challenges presented in the manufacturing process.

A simple procedure for the crude purification of a chromoprotein suitable for a general chemistry laboratory. The protein, phycocyanin, is easy to purify and very stable. It contains a chromophore that can serve to report the integrity of the protein structure: the chromoprotein is dark blue when the protein is folded in its native conformation, and it turns a very pale blue when the protein is unfolded or denatured.

A Simple Method for Demonstrating Enzyme Kinetics Using Catalase from Beef Liver Extract Kristin A. Johnson
A simple visual method of demonstrating enzyme kinetics using beef liver catalase. Filter paper is saturated with beef liver extract and placed into a solution of hydrogen peroxide. The catalase in the extract decomposes the hydrogen peroxide to water and oxygen. Oxygen forms on the filter paper, and the filter paper rises to the top of the beaker. Catalase activity is measured by timing the rise of the enzyme-soaked filter paper to the top of beakers containing different concentrations of hydrogen peroxide.

Consumer Views on Chemical Additives: Are They Natural or Synthetic? A Non-Laboratory-Based Project A. S. Cotterill, D. N. John, and Y. S. Teh
Results of a study demonstrate that consumers are not well informed about identifying natural products but do recognize names to which they have been exposed. Consumers also appreciate that natural compounds can come from a variety of sources and can be synthesized, and that a natural substance is not necessarily good for you or better than a synthetic substance. However, despite this knowledge, consumers do prefer products that contain natural or natural-sounding additives.

The Fizz Keeper, a Case Study in Chemical Education, Equilibrium, and Kinetics Reed Howald
The chemistry of the loss of carbonation from carbonated beverages on storage is considered. Increasing the pressure of CO2(g) will restore carbonation, but an increase in pressure adding air should not affect the equilibria. It can and does, however, affect the kinetics-the rate at which a new equilibrium is established. Thus the Fizz Keeper is effective for storage of resealed pop containers for hours, but not for periods of weeks or months.

"Chemical-Free" Foods: An Investigation of Student's Definitions of a Chemical Gayle Nicoll
This study investigated the pervasiveness of these views among students enrolled in a freshman level college general chemistry course. It was found that only 30 percent of the students in second semester held a scientific definition of a chemical, while another 30 percent held a popular definition. The remaining 40 percent held views intermediate between these.
