Reviews growing concern about the quality of tapwater as a source of drinking water. Investigates the preferences of people for tapwater, filtered tapwater, and commercially bottled water, before and after a taste test. Results indicate a preference for bottled water before the taste test and a preference for filtered water after tasting. Contains…

Presents the study of declining Anuran populations as a mystery to be solved by teams of investigators. Student teams research assigned topics and develop scenarios to explain the declining populations. Provides background information on Anurans along with clue sheets. Describes possible extensions for the activity and provides the source for a…

Examines pre-/posttests, land use plans, and oral presentations in order to assess whether the Conservation Camp was successful in increasing the knowledge and abilities of young people to consider water-quality impacts in land-use decisions. Results indicate that the camp was an effective method of teaching young people water-quality land-use…

Describes using microcosms as a mechanism for teaching lake acidification caused by acid input. (ZWH)

Presents a three-day mini unit on purification of drinking water that uses the learning cycle approach. Demonstrates the typical technology that water companies use to provide high-quality drinking water. (JRH)

Describes three programs that are a result of a bead filtering system used for aquaculture developed in a university setting. Two of the programs described are career-training experiments for high school and junior high school students. (LZ)

Describes a comparative study project where seventh grade students tested water samples from 10 cave sites that had been tested 24 years ago in a study that had attempted to determine if pollution in the environment had reached cave water. Discusses lab skills and some results of the study. (JRH)

Describes a free online service that can enhance water quality studies by allowing students from across the United States to share data. This telecommunications service from the University of Louisville combines chemistry, biology, environmental science, mathematics, and computer technology into interdisciplinary water quality studies. (JRH)

Describes a multidisciplinary, team-taught introductory course on water. Focuses on the chemistry section of this course which used a systems approach to introducing students to the aquatic chemistry of natural systems. (Contains 16 references.) (Author/ASK)

This paper describes how a water monitoring program uses a science research paper to help students apply knowledge learned from the field, the lab, and class discussion. The application consists of examining water quality data of a river and determining what factors had an impact on the river, either biotic or abiotic. Students are asked to…

A method for demonstrating eutrophication that can be used as a simple illustration of the phenomenon or as a basis for problem-solving activities is presented. A sample worksheet with procedures for this activity and discussion questions is included. (Author/KR)

Presents an experiment on collecting data while measuring the dissolved-oxygen levels in Thames River tap water straight from the water mains and dissolved-oxygen levels in rainwater containing Hornwort water weed over 24 hours. (Author/ASK)

This guide aids in finding water quality solutions to problems from sediment, animal wastes, nutrients, pesticides, and salts. The guide allows users to learn the fundamental concepts of water quality assessment by extracting basic tenets from geology, hydrology, biology, ecology, and wastewater treatment. An introduction and eight chapters are…

Presents an exercise that gives students a real feeling for experimental errors and demonstrates the importance of frequent repetition and averaging. (JRH)
