Employs a first-person phenomenological approach to describe an expedition for teachers from the uppermost beginning of a Northern Rocky Mountain watershed to its river output at the bottom. Focuses on the roles of people and place in the construction of new knowledge about the environment. Takes traditional curriculum theory a step beyond simple…

Describes how at Ohio University, the design and construction of the initial phase of a campuswide chilled water system is proving to cut electric costs. (EV)

Coastal communities face difficult choices regarding the use if their waterfront resources. The complexity of issues, contradictory scientific evidence, different visions of the future, and uncertainty regarding community interests add to the difficulty of reaching consensus. The community of Oconto, Wisconsin, attempted to integrate technical and…

Explores ideas for controlling mold buildup in educational facilities. Topics addressed include source identification, prevention of standing water, carpet cleaning, and odor removal tips following water damage. (GR)

Are these students talking about their classmates? No, they are describing the Signing Avatar characters--3-D figures who appear on the EnViSci Network Web site and sign the resources and activities in American Sign Language (ASL) or Signed English (SE). During the 2003?04 school year, students in schools for the deaf and hard of hearing…

The increase in NMR relaxation rates as a result of dissolved paramagnetic species on the sample of superoxygenated drinking water is demonstrated. It is concluded that oxygen content in NMR samples is an important issue and can give rise to various problems in the interpretation of both spectroscopic and NMR imaging or relaxation experiments.

In this final, collaborative paper in the "Learning to be drier" edition, we reflect on and draw together some of the key threads from the diverse narratives in our four site papers from across the southern Murray-Darling Basin. Our paper title, "Wicked learning", draws on a recent body literature (Rittel & Webber 1973)…

This experiment was conducted to test the predictions of two behavioral-economic approaches to quantifying relative reinforcer efficacy. The normalized demand analysis suggests that characteristics of averaged normalized demand curves may be used to predict progressive-ratio breakpoints and peak responding. By contrast, the demand analysis holds…

The purpose of this study was to investigate students' conceptions about watersheds. Specifically: (1) What are students' conceptions of a watershed? and (2) In what ways might students' conceptions vary by grade level and community setting? This study was descriptive in nature and reflected a cross-age design involving the collection of…

This article discusses the need for physical protection and care of infants and young children and families. One of the most important preventable challenges to children's physical safety and protection is toxic substances in their environment. Many toxic substances that affect the central nervous system are in drinking water, soil, air, and areas…

Climate change is having a major effect on water cycles. There is an increased intensity and frequency of severe storms resulting in flooding. Floods in other parts of the world cause death on a major scale. Meanwhile across the planet, one billion people (a sixth of the world's population) do not have access to safe drinking water, and two…

A challenging task in physical studies of the upper ocean using underwater sound is the interpretation of high-resolution acoustic images. This paper covers a number of basic concepts necessary for undergraduate and postgraduate students to identify the most distinctive features of the images, providing a link with the acoustic signatures of…

The paper reports on a study of five pupils' (13-14 years old) learning about freshwater pollution and related theoretical concepts such as drainage basin and water pollution. Much of the instruction is devoted to fieldwork conducted at a polluted lake and other practical activities designed to promote the pupils' understanding of the central…

Seeking to raise money for new academic buildings and programs, Indiana University's board of trustees is exploring outsourcing its "auxiliary-service" units. These units manage printing and food services, the university's bookstores, campus motor pools, and other functions. To prevent job loss and wage cuts among hundreds of long-term…

Increasingly, people are being asked to make decisions about water use in the semi-arid regions of the United States. "Good decisions" depend on an understanding of the linkages between sustainability of the resource, management, and economic development. This article reports on findings from a water quality survey conducted in Colorado,…
