additional resources for teachers
The following are some resources that are related to water and are available from other organizations.
“What’s in Your Water?” by Betty Jo Chitester and Weslene T. Tallmadge, Chemistry Department, Gannon University, Erie, Pennsylvania is a directed case study that uses a fictionalized story about a family that has recently moved to the Washington DC area and is confronted with a situation involving lead contamination of the municipal water supply. Students learn how basic chemical principles apply to human health and safety and, through selected readings, are introduced to sources of lead drinking water as well as background information on municipal water supply treatment. The case includes opportunities for exploring the ethical issues involved in the DC lead contamination incident as well as for getting some practice in applying general chemical principles such as solubility and concentration units. This case would be appropriate for use early in a fundamental chemistry course, after students have been introduced to ionic compounds, atomic structure, ions, and unit conversions.
