Addresses questions about the nature, source, and history of acid rain. In addition, discusses the questions: Why is acid rain a problem? Is acid rain getting worse? What is the threat of further problems? Concludes that it is time to act on the problem and recommends an appropriate course of action. (JN)

General methods for determining skilled labor needs for water supply and wastewater treatment plant operation as applied in Turkey are outlined along with a model program for training personnel to meet these needs. (DC)

Provided are details for a game designed to help secondary school or college students understand the types of problems encountered in applied hydrobiology and the financial and time constraints involved in their solution. (PB)

This article is the first of three articles in a series on the acid rain problem in recent years. Discussed are the causes of acid precipitation and its consequences for the abiotic and biotic components of the terrestrial and aquatic ecosystems, and for man-made materials. (Author/SA)

University of California Sea Grant Extension Program provides training and technical assistance to fishers, farmers, planners, and conservationists on projects such as coastal ecosystem health, marine environmental protection, fisheries management, aquaculture, salmon habitat restoration, and controlling nonpoint-source pollution; supports…

Described is a skit to be performed in an elementary school classroom about the water cycle. Included are a list of materials, procedures, and suggestions for role cards for the players. (CW)

Discusses a course at the University of Wisconsin-Eau Claire which improved instruction in physical hydrogeology, chemical hydrogeology, and water resources. Describes 14 laboratory activities including objectives, methods, and a list of equipment needed. (Author/MVL)

Presents one approach to handling the trade-off between reducing uncertainty in environmental assessment and management and additional expenses. Uses the approach in the evaluation of three alternatives for a real time river water quality forecasting system. Analysis of risk attitudes, costs and uncertainty indicated the levels of socioeconomic…

More than 53 million children and 6 million adults in the United States spend their days in elementary and secondary schools. Reducing environmental risks inside these buildings is critical to maintaining the public health. Almost all of New England's children will spend a large portion of their childhood in school. To help children stay healthy,…

This study examined the impact of two epistemic commitments on the quality of college students' scientific reasoning in the domain of hydrostatics. These were the commitment to the consistency of theory with prior knowledge and commitment to the consistency of theory with evidence. Participants were 12 sophomore science majors enrolled in a large…

The problem of environmental pollution has assumed an unprecedented proportion in many parts of the world especially in Nigeria and its Niger-Delta region in particular. This region is bedeviled with this problem perhaps owing to interplay of demographic and socio-economic forces coupled with the various activities that revolve round the…

This article presents a model for the development of an environmentally oriented unit designed to be implemented as an integral part of the science core curriculum. The program's main goal is encouraging students at the junior high-school level to develop systems-thinking and environmental insight as a basis for environmental literacy. A…

The present study deals with a school-based professional development trajectory for secondary science teachers, aiming at scaffolding teachers in open-inquiry teaching for the topic of water quality. Its design was based on the leading principle of "guiding by scaffolding". Seven experienced teachers participated in institutional…

Teaching ecological concepts in schools is important in promoting natural science and environmental education for young learners. Developing educational programs is difficult, however, because of complicated ecological processes operating on multiple levels, the unlimited nature of potential system interactions (given the openness of systems), and…
