A project of the National Science Foundation, ChemConnections modules use guided, discovery-based learning activities to promote a deep understanding of a broad range of chemistry concepts and problem-solving techniques. Each module poses a central question for example, "What's in a Star?" or "How Can We Make Our Water Safe to Drink?" that students investigate through guided discussions, collaborative laboratory work, reading and writing assignments, case teaching, policy simulations, Web research, and videos.

This introductory text explores the structure/solubility relationships of organic compounds, explains how to extract pesticide residues from fruits and vegetables, analyzes the extract for pesticide content using gas chromatography, and uses the data collected as a basis for discussion about the issues surrounding pesticide regulation. Intended for use in the laboratory portion of an introductory environmental chemistry or general chemistry course.

This introductory laboratorymanual will help students design a sampling plan, understand theinstrumental and analytical techniques used for the assessment ofwater quality, learn how to interpret data and use statisticalanalyses, and apply scientific reasoning to an environmentalproblem. Ideal for use in the laboratory portion of anintroductory environmental chemistry or general chemistry course,the manual provides substantial background information aboutwater chemistry and gives the instructor a choice of proceduresfor each analysis, from instrument-intensive techniques to thoserequiring nothing more than a buret and a few chemicals.AncillariesAdetailed Instructors' Manual is available for adopting professors.
