Compiled are abstracts and indexes to selected print and non-print materials related to wastewater treatment and water quality education and instruction, as well as materials related to pesticides, hazardous wastes, and public participation. Sources of abstracted/indexed materials include all levels of government, private concerns, and educational…

Although progress has been made in curbing industrial pollutants in larger communities, small, nonindustrial communities lack strategies for reducing unregulated toxic sources to the influent stream. This article outlines one environmental organization's model for reducing these toxic sources that can be used to help small communities nationwide.…

Evaluates the state of drinking-water quality in the United States. Maps the number of reported cases of waterborne disease by state and lists 23 cities with violations of contaminant standards 1 or more times from 1992 to 1994. Briefly describes four primary drinking-water pollution causes and six management options. (LZ)

This is the teacher's guide to a student text designed to help users understand: (1) what groundwater is and how it is part of the hydrologic cycle; (2) how groundwater travels; (3) how groundwater is stored, purified, or contaminated; (4) the five physiographic regions in Virginia that store groundwater; and (5) the everyday activities that help…

Long Island Sound is an estuary of national significance and provides important economic, recreational, and aesthetic value to the citizens of Connecticut and New York. Investigations have been conducted regarding living marine resources and nutrient loading. However, Long Island Sound is often overlooked as an educational resource. This guide is…

Discusses the management of the earth's water resources. Describes the global water cycle and the status of water pollution. Recommends that a water-management project should lean toward increasing the efficiency of water consumption rather than toward increasing the supply of water. (YP)

I have found that students easily understand that a measurement cannot be exact, but they often seem to lack an understanding of why it is important to know "something" about the magnitude of the uncertainty. This tends to promote an attitude that almost any uncertainty value will do. Such indifference may exist because once an uncertainty is…

Differentiation and integration played large roles within classic developmental theories but have been relegated to obscurity within contemporary theories. However, they may have a useful role to play in modern theories as well, if conceptualized as guiding principles for analyzing change rather than as real-time mechanisms. In the present study,…

The Pecos River of the nineteenth century, unlike its faint twenty-first century shadow, was a formidable watercourse. The river stretches some 755 miles, from the Sangre de Cristo Mountains northeast of Santa Fe to its eventual merger with the Rio Grande. Control over the public domain of southeastern New Mexico came from controlling access to…

A comparison of capillary rise and nucleation is presented. It is shown that both phenomena result from a balance between two competing energy factors: a volume energy and a surface energy. Such a comparison may help to introduce nucleation with a topic familiar to the students, capillary rise. (Contains 1 table and 3 figures.)

In this Activity, students perform quantitative calorimetric measurements on samples of ice/water heated by incandescent light bulbs and with convection with room-temperature surroundings.

Educators in many disciplines recognize interdisciplinary teaching as effective for student learning. This article provides a model for developing an interdisciplinary literacy and science study with states of water as the core scientific study with corresponding literacy strategies. Authors have included suggestions for children's literature as…

In the author's book titled "The Incredible Water Show," the characters from "Miss Alaineus: A Vocabulary Disaster" used an ocean of information to stage an inventive performance about the water cycle. In this article, the author relates how she turned the story into hands-on science teaching for real-life fifth-grade students. The author also…

Materials for teaching a unit on water pollution are provided in this teaching package. These materials include: (1) a student reading booklet; (2) a reference booklet listing a variety of popular chemical, biological, and physical tests which can be performed on a local waterway and providing information about the environmental effects and toxic…

The benefits of using data logging to teach "how science works" are presented. Pedagogical approaches that take advantage of other school ICT are briefly described. A series of simple, quick experiments are given together with their resulting charts. Examples of the questions that arise from the charts show how the rich data lead to the refinement…
