A Project Based Learning (PBL) methodology was used in the practical laboratories of the Advanced Physical Chemistry department. The project type proposed simulates "real research" focusing on sol-gel synthesis and the application of the obtained sol as a stone consolidant. Students were divided into small groups (2 to 3 students) to…

Operation Cleansweep is a free pesticide disposal program that has operated in Florida since 1995. The program is open to commercial facilities, including agricultural production establishments, golf course operators, and pest control companies. Since its inception, the program has had more than 1,700 participants and collected more than 1,000,000…

Indoor environmental quality (IEQ) may not be the only aspect of a green school, but it is one of the most significant. Advanced environmental instrumentation technology now provides school business officials with tools to measure the factors that contribute to their schools' IEQ. These new devices make it possible to identify the toxic or…

Some simple chemistry is used to demonstrate how Fe(II) ions, formed during iron corrosion in acid aqueous solution, can reduce toxic Cr(VI) species, forming soluble Cr(III) and Fe(III) ions. These ions, in turn, can be precipitated by neutralizing the solution. The procedure provides a treatment for industrial wastewaters commonly found in…

College and university science programs generate hazardous waste that must be dealt with and disposed of in accordance with state and federal regulations. During a recent renovation and addition project for the State University of New York at Plattsburgh (SUNY Plattsburg), the author was contracted to analyze existing regulations, research best…

Migrant and seasonal farmworkers are typically Spanish-speaking, Latino immigrants with limited formal education and low literacy skills and, as such, are a vulnerable population. We describe the development of the "Pesticides and Farmworker Health Toolkit", a pesticide safety and health curriculum designed to communicate to farmworkers…

Ten or even five years ago, it would have been a major undertaking for a school district to convert to a comprehensive green cleaning program. At that time there was little precedence and no "roadmaps" for doing so. Thus schools faced numerous challenges that included: (1) what defined a green cleaning product; (2) should a comprehensive program…

Lead is a good example of a metal that was used for many things over centuries--in water pipes, paints, on roofs, and in leaded petrol, for example--but was superseded as scientists discovered "new" metals, and because its toxicity became a problem. It was originally an important element in pewter utensils, alloyed with tin; it made the…

As sensors and computers become smaller and smaller, it becomes possible to add intelligence or smartness to common items. This is already seen in smart appliances, cars that diagnose their own maintenance problems, and military hardware that is something straight out of a science fiction book. In this article, the author looks at a design…

Introducing students to the process of scientific inquiry is a major goal of high school and college labs. Environmental toxins are of great concern and public interest. Modifications of a vertebrate developmental toxicity assay using the frog Xenopus laevis can support student-initiated toxicology experiments that are relevant to humans. Teams of…

The ingredient lists of your shampoo, makeup, and moisturizer are likely to include a dizzying number of unknown ingredients. What these ingredients are and do is a mystery to most consumers. However, many cosmetics contain ingredients that are linked to health problems and environmental concerns. While examining every ingredient in your beauty…

"Towards Healthy Schools: Reducing Risks to Children" is the fourth in a series of triennial state of the states' reports from Healthy Schools Network and its partners in the Coalition for Healthier Schools, dating from 2006. Previous reports assessed state-by-state environmental health hazards at schools, offered compelling personal…

Previous research identifies changing world cultural norms as the impetus for a worldwide trend promoting environmentalism. However, the extent to which countries comply with the norms promoted and codified by environmental organizations and treaties has been less rigorously tested. Suspected noncompliance is generally explained as "decoupling"…

This article discusses where teachers stand from a legal point of view when pupils, who have been told to wear eye protection, take it off during the practical lesson, and an accident happens. It also discusses the disposal of dissection and other waste from animal parts used in school science. (Contains 1 footnote.)

Chemicals are ubiquitous in the environment, and human exposure to them is inevitable. A benchmark investigation of industrial chemicals, pollutants, and pesticides in umbilical cord blood indicated that humans are born with an average of 200 pollutants already present in their bodies. The study found a total of 287 chemicals, of which, 180 are…
