This article describes several applications of the use of solubility data. It is not meant to be exhaustive but rather to show that knowledge of solubility data is required in a variety of technical applications that assist in the design of chemical processes. (Contains 3 figures and 1 table.)

Intra-household water use and management from a gender perspective has remained a relatively under-researched theme in developed countries. Australia is no exception, with the lack of research particularly evident in the many rural and peri-urban communities. These communities have experienced significant water scarcity in recent years. In this…

In this article I describe an experiment involving the Leidenfrost phenomenon, which is the long lifetime of a water drop when it is deposited on a metal that is much hotter than the boiling point of water. The experiment was carried out with high-school students. The Leidenfrost point is measured and the heat laws are used to estimate the…

Sustainability is one of the leading issues of this time. Climate change is real, and widespread commitment and creativity are needed to combat its negative effects. Higher education is the seedbed of the sustainability movement. Much climate research and environmental science takes place on college and university campuses, which are, by their…

In 1897, about half of all American municipalities used lead pipes to distribute water. Employing data from Massachusetts, this paper compares infant death rates in cities that used lead water pipes to rates in cities that used nonlead pipes. In the average town in 1900, the use of lead pipes increased infant mortality by 25 to 50 percent.…

The current drought conditions in the United States are correlated with inadequate infrastructure, a drop in the levels of the Great Lakes, desertification, and migration. Taken individually, none of these problems may seem alarming. However, in combination, freshwater shortages are a crisis in many areas of the United States. In order to develop…

The integration of student research into a general chemistry laboratory and an environmental geology course has been evaluated for its effectiveness to improve (i) student attitudes about science and chemistry, (ii) student understanding of the nature of experimental science and the scientific method, and (iii) student perceptions of the…

Developed to increase public awareness of the Chesapeake Bay ecosystem, this guide provides information and suggestions for improving the quality of life in the Bay area. Contents include background information and a "what can you do" section on separate topics related to: (1) resources of the Chesapeake Bay watershed; (2) streambank…

This document provides an overview of Peace Corps water and sanitation activities, five case studies (Thailand, Yemen, Paraguay, Sierra Leone, and Togo), programming guidelines, and training information. Each case study includes: (1) background information on the country's geography, population, and economics; (2) information on the country's…

This handbook is designed to meet the aquatic education needs of Minnesota secondary teachers and students (aquatic education referring to the study of freshwater systems). The handbook is divided into three parts. Part 1 (an introduction) provides an overview of aquatic education, a description of the use of the handbook, and two indices to…

How state agencies have addressed privatization in a service setting (municipal wastewater treatment) is discussed. The implications for evaluations of many types of programs, particularly those of local service programs regulated by the states, are explored. Data from a national survey of state environmental regulatory agencies are highlighted.…

Excessive production of pro-inflammatory mediators by activated brain microglia plays an important role in abnormal neuronal function and cognitive deficits. Studies have shown that the intake of flavonoids is inversely related to cognitive decline and dementia in people 65 years of age or older. Luteolin, a flavonoid found in high concentrations…

The objective of many environmental education programs is to promote pro-environmental attitudes and behaviors in students. However, evaluation of these programs has focused on asking participants what they think (attitudes) and what they do (behaviors) regarding the environment problems through self-report questionnaires and interviews. These…

This study aimed at identifying prospective chemistry teachers' misconceptions of colligative properties. In order to fulfill this aim, a diagnostic test composed of four open-ended questions was used. The test was administered to seventy-eight prospective chemistry teachers just before qualifying to teaching in secondary schools. Nine different…

Dwindling resources for tertiary education, has resulted in reduced emphasis on intensive, small group, staff-student collaborative project-based service learning. However, training scientists to manage significant issues, such as sustainable water use, requires an ability to engage both industry and community stakeholders. This paper describes…
