Characteristics of ground water and aquifers are explained to facilitate understanding of their importance in domestic water supplies. Problems of over usage, contamination, and regulation are enumerated and a national protection policy is advocated. (BL)

The concept of health is not only a specific criterion for evaluation of water quality delivered by a distribution system but also a suitable paradigm for overall functioning of the hydraulic and structural components of the system. This article views health, despite its complexities, as the only criterion with suitable depth and breadth to allow…

Five high schools in British Columbia, Canada, participated in an atmospheric sciences project during the winter of 2006-07 established by researchers at the University of Calgary. Precipitation gauges and temperature and relative humidity probes were installed at each school and students were asked to collect a water sample each day that…

Treadle pump (TP) technology has been promoted by Enterprise Works in West Africa as an alternative to the traditional rope and bucket irrigation. The aim is to improve output and incomes and reduce poverty among farm households. This paper reports a short term (two years) assessment of the dynamics of its adoption and impacts, with a special…

"Teaching Science" has, as one of its predecessors, the "Investigating" journal, which first appeared in 1988. Looking back ten years, the winner of the "Most Valuable Paper Award" for 1999 was Kimberley Pressick-Kilborn for her article--"Steps to Fostering a Learning Community in the Primary Science…

This is a ready-to-use simulation that has high school students portraying all of the key players that decide how water from the Colorado River will be allocated. Students act as judges, lobbyists, news analysts, and even protesters during a mock water conference. Water supply is promised beyond nature's delivery, so the problem is real and will…

In order to demonstrate how plants remove water from the soil and release it to the atmosphere, students compared open- and closed-growing systems using drought-tolerant and higher water requirement plants. Then, students designed a drought-tolerant garden demonstrating what they had learned. Through this experience, students not only learned…

Learning about states of matter is fun and exciting when students, acting as water molecules, role-play moving from a solid to a liquid to a gas. The 5-E lesson plan model provides the framework for this activity, ensuring that students actively engage in inquiry science while creatively constructing knowledge. (Contains 2 figures.)

A central problem in higher education is how to best develop in students interdisciplinary thinking and application skills necessary to work and engage effectively in the twenty-first century. Traditional university structures make addressing this problem especially challenging. Using as a model courses with diverse perspectives on water taught by…

The new paradigm for student research should be articulations and collaborations with local governmental, academic, and civic entities. This will enable students to make lasting contributions to bettering their communities through scientific research, and to better understand the practical relevance of science. This article presents two such…

The Environmental Quality Instructional Resources Center in Columbus, Ohio, acquires, reviews, indexes, and announces both print (books, modules, units, etc.) and non-print (films, slides, video tapes, etc.) materials related to water quality and water resources education and instruction. In addition some materials related to pesticides, hazardous…

One means of preventing the top of a pond from freezing involves running a circulating pump near the bottom to agitate the surface and expose it to air throughout the winter months. This phenomenon is similar to that of the flowing of streams in subzero temperatures and to the running of taps to prevent pipe bursts in winter. All of these cases…

As an astronomy instructor, I am always looking for commonly observed Earthly experiences to help my students and me understand and appreciate similar occurrences elsewhere in the solar system. Recently I wrote a short TPT article on frost. This paper is on the related phenomena of precipitation. Precipitation, so common on most of the Earth's…

A basic introduction to concept of a solvation shell around an apolar solute as well as its detection is presented. The hydrophobic solvation of toluene is found to be a good teaching example which connects macroscopic, phenomenological thermodynamic results with an atomistic point of view.

This booklet is designed to help people make environmentally responsible decisions. This activity booklet is targeted at students as part of a learning campaign to help Canadians improve their understanding of the environment. The imaginary journey From the Mountains to the Sea is a trip along the Eco River following molecules of water from high…
