The theoretical basis of reactive oxygen species and their impact on health issues are relatively easy to understand by biomedical students. The detection of reactive oxygen species requires expensive equipment, the procedures are time consuming and costly, and the results are hard to interpret. Moreover, cause-and-effect relationships in the…

This article connects Extension education and the Healthy Homes Initiative. Background on housing research and education is provided in the context of four issues (toxic materials, dangerous gases, hazards related to asthma, and other residential hazards). The federally funded Healthy Homes Partnership is described, and implications for…

This project involved developing a method to remediate large quantities of aqueous waste from a general chemistry laboratory experiment. Aqueous Ni(II) waste from a general chemistry laboratory experiment was converted into solid nickel hydroxide hydrate with a substantial decrease in waste volume. The remediation method was developed for a…

E-waste contains hazardous chemicals and materials that threaten the environment and human health, when improperly disposed. This study examined levels of awareness of e-waste disposal among university students in Ghana, and their proenvironmental decision-making using two outcome variables: "knowledge on environmental impact and policy…

Fascination with fireworks and pyrotechnics can be used for educational purposes. Several aspects of pyrochemistry such as redox reactions, flame colors, or the theory of combustion can be incorporated in the curriculum to illustrate some basic chemical principles, guaranteeing a lesson that will be engaging and memorable. Beyond classic…

The center for Disease Control and Prevention (CDC) has found that 1 in 110 children in the US have been diagnosed with Autism Spectrum Disorder (ASD), up from 1 in 150 in 2007. A study in the "Journal of Pediatrics" in October 2009 revealed similar numbers. Parents of 1 in 90 children reported that their child has ASD. That report is now 1 in 58.…

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…

This paper presents an analysis of an environmental justice (EJ) program adopted by the South Coast Air Quality Management District (SCAQMD) as a part of its regulation to phase out a toxic chemical used by dry cleaners. SCAQMD provided financial incentives to switch early and gave establishments in EJ neighborhoods priority in applying for…

Many education institutions have embraced the growing push for sustainable design and have built environmentally friendly facilities that use resources more efficiently. But the plaudits that administrators receive for LEED certification and other recognition of their efforts may be meaningless if the green commitment ends when a building is…

This activity is designed to provide students with an overview of environmental health and to encourage them to think critically about how they can minimize their potential negative health impacts from environmental exposures. Objectives: Students will (a) define environmental health, (b) analyze media wherein environmental health issues are…

Introductory physics courses present the basic concepts of radioactivity and an overview of nuclear physics that emphasizes the basic decay relationship and the various types of emitted radiation. Although this presentation provides insight into radiological science, it often fails to interest students to explore these concepts in a more rigorous…

Investigations that integrate concepts from geological sciences with biology and chemistry are rare. The authors present an investigation that introduces high school students to microbe-mineral interactions by tying together anaerobic respiration, reduction reactions, metal ion solubility, and groundwater pollution. During the investigation,…

We examine the effects of the Cleveland Metropolitan School District's (CMSD) districtwide efforts to improve school safety, order, and conditions for learning. These approaches include implementing (1) a social and emotional learning program for elementary students (PATHS); (2) a planning model for students exhibiting academic or nonacademic…

Much of our understanding of metabolic pathways has resulted from the use of chemical and isotopic labels. In this experiment, a heavy isotope of carbon, [superscript 13]C, is used to label the product of the well-known RuBisCO enzymatic reaction. This is a key reaction in photosynthesis that converts inorganic carbon to organic carbon; a process…

The vast majority of energy necessary for cellular function is produced in mitochondria. Free-radical production and apoptosis are other critical mitochondrial functions. The complex structure, electrochemical properties of the inner mitochondrial membrane (IMM), and genetic control from both mitochondrial DNA (mtDNA) and nuclear DNA (nDNA) are…
