Describes the success of a West Virginian program of extension education for the training of sewage treatment plant operating personnel. (AN)

Discusses evidence of water pollution by nitrogen and phosphorous from fertilizers. Concludes that restrictions should be on watershed, not state or national basis. 35 references. (AL)

A bibliography of contemporary publications on an adequate supply of usable water" compiled to be of assistance to interested students, teachers and librarians. (NH)

Assesses the knowledge and perceptions of Michigan residents about groundwater in order to develop a comprehensive educational program and provide baseline information to document the program's impact over time. (Author/CCM)

The preparation of 7-hydroxy-3-carboxycoumarin starting from 2,4-dihydroxybenzaldehyde, and malonitrile, by one-pot consecutive reactions, carried out in water under heterogenous conditions is presented. The experiment encourages students to think in terms of reaction mechanisms.

The omission of the concentration of water in the atmosphere and the variation in it is discussed. The water vapor, carbon dioxide and methane are the important dominant greenhouse gases.

Previous failures to condition preferences for the unacceptable taste cues sucrose octaacetate (SOA) and citric acid (CA) using a reverse-order, differential conditioning procedure (Forestell & LoLordo, 2000) may have been the result of low consumption of the taste cues in training or of their relatively low acceptability to rats that are thirsty…

It is quite easy to make a version of the well known Cartesian diver experiment that uses two immiscible liquids. This allows students to test their knowledge of density and pressure in explaining the diver's behaviour. Construction details are presented here together with a mathematical model to explain the observations.

Our physics students like to watch a ball bouncing underwater. They do this by dropping a weighted plastic ball into a 1000-ml cylinder filled with a linearly stratified salt-water solution at room temperature. The ball oscillates and comes to rest at about mid-depth. Its motion is analogous to the damped vertical oscillations of a mass hanging…

Here is a quick way to measure the index of refraction of water using the phenomenon of total internal reflection.

Did you know that the water you use today is the same water that was used millions of years ago? How is this possible? Water is continuously replenished through a naturally occurring process known as the water cycle. To help students learn about this important concept, an eight-day unit was created for fifth-grade students to explore the water…

Education administrators do not have to be deeply committed to the ecology movement to see the value of conserving energy and providing more environmentally friendly facilities. Reducing energy costs frees up funds for learning programs. Providing more healthful facilities can help students and teachers ward off illness and disease and perform…

With the global crises facing the planet that bring major implications, (Hart & Nolan, 1999; Hungerford & Simmons, 2003) it is imperative that there be an environmentally literate citizenry who can identify, solve, and prevent environmental issues. Since middle school students are evolving into participating citizens and are developing the…

Our paper explores how and what adults living and working in the Alpine region of Victoria understand and are learning about the changes to water availability, in a time when the response to water availability is subject to extensive debate and policy attention. Interviews for this study were conducted in the towns of Bright and Mount Beauty, with…
