A Simplified Model To Predict the Effect of Increasing Atmospheric CO2 on Carbonate Chemistry in the Ocean  Brian J. Bozlee, Maria Janebo, and Ginger Jahn
The chemistry of dissolved inorganic carbon in seawater is reviewed and used to predict the potential effect of rising levels of carbon dioxide in the atmosphere. It is found that calcium carbonate may become unsaturated in cold surface seawater by the year 2100, resulting in the destruction of calcifying organisms such as coral.

Experimental Determination of Ultraviolet Radiation Protection of Common Materials  Susana C. A. Tavares, Joaquim C. G. Esteves de Silva, and João Paiva
The oxidation of iodide is used as an indicator for the degree of exposure to UV radiation and to investigate the protection given by a simulation of ozone using plexiglass plates, sunscreen lotions, cotton cloth with different colors, and aqueous solutions with different concentrations of natural organic matter.

"Holes" in Student Understanding: Addressing Prevalent Misconceptions Regarding Atmospheric Environmental Chemistry  Sara C. Kerr and Kenneth A. Walz
This study evaluated the misconception that global warming is caused by holes in the ozone layer, other ideas surrounding atmospheric chemistry that are responsible for the entanglement of the greenhouse effect and ozone depletion in students' conceptual frameworks, and the effectiveness of computer-based online data-analysis exercises to address these shortcomings.

Geographical Information Systems (GIS) Mapping of Environmental Samples across College Campuses  Kathleen L. Purvis-Roberts, Harriet P. Moeur, and Andrew Zanella
In this laboratory experiment, students take environmental samples (concentrations of nitrogen dioxide) and geospatial coordinates with a global position systems unit at various locations around campus, map their data on a geo-referenced map with geographical information systems software, and compare their results to those observed by governmental agencies.

Chemical Behavior  Paul G. Jasien
In order to increase student understanding of the seemingly confusing behavior of chemical substances involved in environmental chemistry, an analogy between chemical and human behavior is presented. The analogy focuses on how the same individual can behave differently due to his/her social surroundings.
