Kinetic Analysis of Amylase Using Quantitative Benedict's and Iodine Starch Reagents  Beverly Cochran, Deborah Lunday, and Frank Miskevich
This laboratory emphasizes that enzymes mediate the conversion of a substrate into a product and that either the concentration of product or reactant may be used to follow the course of a reaction. It does so by using an inexpensive scanner and open-source image analysis software to quantify amylase activity through the breakdown of starch and the appearance of glucose.

Sedimentation Time Measurements of Soil Particles by Light Scattering and Determination of Chromium, Lead, and Iron in Soil Samples via ICP  Patricia Metthe Todebush and Franz M. Geiger
In this two-part general chemistry laboratory activity, students study soil samples from home and from campus. In part one, the samples are placed in water and the suspended colloid fraction is separated using filtration, followed by a determination of colloid sedimentation rates via light scattering. In part two, the solid phase of the soil samples is dissolved in acid and analyzed for chromium, lead, and iron using an inductively coupled plasma spectrometer. The experiment can be expanded to include arsenic. Through these experiments students can draw conclusions about the physical and chemical behavior of solid components in soil, paying particular attention to their propensity for transporting and chemically transforming pollutants in the environment.

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.

Glass Doesn't Flow and Doesn't Crystallize and It Isn't a Liquid  Stephen J. Hawkes
It is widely believed that glass flows in historic time and it is often asserted that glass is a liquid. The evidence of archeology, geology, and viscosity and of research on glass structure and on conservation of antique glass is examined and the conclusion in the title is reached. These fallacies should not be taught.

A Closer Look at Phase Diagrams for the General Chemistry Course  Stephen A. Gramsch
The information provided by the high-pressure phase diagrams of some simple systems (carbon dioxide, water, hydrogen, and iron) can provide a useful extension to the traditional discussion of phase diagrams in the general chemistry course. At the same time, it can prepare students for a more illuminating presentation of the concept of equilibrium than is possible through the discussion of gas phase, acid-base, and solubility product equilibria alone.

Global Metabolism of Elements: Principles and Applications in Bioinorganic Chemistry - XI  Ei-Ichiro Ochiai
The biosphere, as its members metabolize the elements, can thus contribute to the overall global geocycling of elements. A diagram is used to indicate several different manners of the contribution and their extents of contribution to the geoprocesses. This overall process incorporating the effects of the biosphere is termed here as "global metabolism" and is illustrated for iron, mercury and arsenic.
