Appreciating Oxygen Hilton M. Weiss Photosynthetic flora and microfauna utilize light from the sun to convert carbon dioxide and water into carbohydrates and oxygen. While these carbohydrates and their derivative hydrocarbons are generally considered to be fuels, it is the thermodynamically energetic oxygen molecule that traps, stores, and provides almost all of the energy that powers life on earth.

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.

Teaching Biologically Relevant Chemistry throughout the Four-Year Chemistry Curriculum Sarah R. Kirk, Todd P. Silverstein, and Jeffrey J. Willemsen First-year chemistry students learn introductory chemistry using case studies which deal directly with human health issues and biological processes. Second-year students choose between two equivalent versions of the second-semester course: one that stresses synthetic organic chemistry and another that stresses bioorganic chemistry.

Mineral Analysis of Whole Grain Total Cereal Paul Hooker This article describes the quantitative analysis of the elements iron, zinc, and calcium in Whole Grain Total Cereal, a cereal product that claims to contain 100% of the daily value of several vitamins and minerals. This experiment can be implemented at several instructional levels including chemistry courses for science and nonscience majors, and in more advanced chemistry courses such as quantitative or instrumental analysis.

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. Petracco, Marino. J. Chem. Educ. 2005, 82, 1161.

Let's Drive "Driving Force" Out of Chemistry Norman C. Craig "Driving force" is identified as a misleading concept in analyzing spontaneous change. Driving force wrongly suggests that Newtonian mechanics and determinism control and explain spontaneous processes. The usefulness of the competition of ?H versus ?S in discussing chemical change is also questioned. Entropy analyseswhich consider the contributions to the total change in entropyare advocated.
