Eutrophication of Lake Wingra: A Chemistry-Based Environmental Science Module Ann C. Howe, Leslie Cizmas, and Robert Bereman
The paper describes the development and field test of a curriculum module for introductory chemistry by an interinstitutional, interdisciplinary team representing the disciplines of chemistry, biology, political science, environmental management and computer visualization. The module was designed to show that a serious and common worldwide environmental problem, the eutrophication of freshwater lakes, is directly related to the chemical reactions of phosphates.

Non-existent compounds Dasent, W. E.
The purpose of this review is to examine compounds that do not violate the rules of valence but which are nevertheless characterized by a high degree of instability, and to consider why these structures are unstable or non-existent.
