Background/Context: The issue of how to achieve a racially diverse student population has become increasingly challenging since a 2007 U.S. Supreme Court split decision endorsed the importance of creating diverse schools, while simultaneously limiting the assignment to public schools based on an individual student's race or ethnicity. The article…

At the intersection of online education and preparedness, Johns Hopkins University's (JHU) Center for Public Health Preparedness provides all-hazards preparedness and response training for public health and public safety professionals. This report comes from Jonathan Links' keynote address to the Sloan Summer Research Workshop in Baltimore,…

Showing up at school is critical to a student's success. Students with prolonged or chronic absences from the classroom are likely to fall behind in their studies, and schools with high absentee rates risk the erosion of badly needed funding. As such, it is vital for school and university learning spaces to be environments that do not jeopardize…

The analysis of drinking water for lead, which has well-known health effects, is presented as an instructive example for undergraduate chemistry students. It allows the students to perform an experiment and evaluate to monitor risk factors and common hazard of everyday life.

"Child Care Health Connections" is a bimonthly newsletter published by the California Childcare Health Program (CCHP), a community-based program of the University of California, San Francisco School of Nursing, Department of Family Health Care Nursing. The goals of the newsletter are to promote and support a healthy and safe environment…

Demand for environmentally responsible stewardship is increasing, and the education technology sector is responding. Former L&L Senior Editor Caprice Lawless offers an overview of local and national e-waste legislation and resources for related classroom projects. (Contains 3 resources and 13 online resources.)

A microscale laboratory experiment to investigate the formation and utility of microemulsions is described. Microemulsions are technologically important fluids that can reduce the use of toxic organic solvents. In the experiment, students prepare a microemulsion and compare the solubility of sudan III dye in the microemulsion and in dodecane. They…

Contamination of the environment with heavy metals such as lead presents many health risks. Simple, effective, and field-portable methods for the measurement of toxic metals in environmental samples are vital tools for evaluating the risks that these contaminants pose. This article describes the use of new developments in anodic stripping…

The concentrations of air pollutants in residences can be many times those in outside air, and many of these pollutants are known to have adverse health consequences. Despite this, there have been very few attempts to delineate knowledge of, and attitudes to, indoor air pollution. This study aimed to establish the knowledge of, and attitudes to,…

The age of female puberty appears to have decreased in the United States and western countries as child health and nutrition have improved and obesity has become more prevalent. Also, environmental contaminants, particularly endocrine disruptors, may also play a role in lowering the age of puberty. Puberty at an early age increases the risk of…

Green is often used as a synonym for environmental or ecological, especially as it relates to products and activities aimed at minimizing damage to the planet. Scientists and engineers have long had important roles in the environmental movement. Their expertise is focused on a variety of issues, including increasing energy efficiency, improving…

In this experiment, organic chemistry students perform reactions between three naphthyl acetate derivatives and the diazonium salt Fast-Red TR, under basic conditions. The three naphthyl acetate derivatives used in this study are 2-naphthyl acetate (1a), 6-bromo-2-naphthyl acetate (1b) and 1,6-dibromo-2-naphthyl acetate (1c). The two-step, one-pot…

Concentrations of heavy metals (Cd, Cu, Cr, Pb and Zn) in tissues of Meretrix meretrix Roding (M. meretrix R.), water and sediments from two estuaries were determined. One estuary is located in an urban area of Kota Kinabalu (Likas estuary) and the other in a rural district of Kota Belud (Kota Belud estuary), where both are in Sabah, North of…

This study examined the sensitivity and false-positive error rate of reliable digit span (RDS) and the WAIS-III Digit Span (DS) scaled score in persons alleging toxic exposure and determined whether error rates differed from published rates in traumatic brain injury (TBI) and chronic pain (CP). Data were obtained from the files of 123 persons…

Using the past 3 years of data, for 2003 to 2005, from the National Fire Incident Reporting System (NFIRS) database, the yearly national fire loss for fires on nonadult school properties is estimated at $85 million. Such losses are the result of an estimated annual average of 14,700 fires that required a fire department response. Fires on school…
