In Australia, the impacts of urbanisation and human activity are evident in increased waste generation and the emissions of metals into the air, land or water. Metals that have accumulated in urban soils almost exclusively anthropogenically can persist for long periods in the environment. Anthropogenic waste emissions containing heavy metals are a…

Each year countries suffer great tragedy when natural disasters destroy schools and disrupt children's education. In addition to causing immediate harm to children, there is mounting evidence that the direct impact of natural disasters can translate into a series of indirect long-term effects. For some time, multilateral and bilateral development…

The 21st -century learning paradigm requires teachers to provide teaching materials that can develop students' thinking skills. This research aims to determine the effect of the web module science integrated local batik potential toward the thinking ability of seventh-grade students of junior high school. The research method used was…

Alternative farming techniques are often more efficient and conserve resources more effectively than conventional farming, which can harm the environment with pesticides and synthetic fertilizers (Pimental 2005). To learn the theory, application, and related science concepts of sustainable farming techniques, students can collaborate to create an…

Presented is a project-based learning (PBL) laboratory approach for an upper-division environmental chemistry or quantitative analysis course. In this work, a combined laboratory class of 11 environmental chemistry students developed a method based on published EPA methods for the extraction of dichlorodiphenyltrichloroethane (DDT) and its…

In seeking an avenue to save money, an urban city made a choice to alter the drinking water for its residents and created a crisis, which all community stakeholders were unprepared to address. The Flint water crisis has been given national attention by celebrities and politicians, but the long-term issues related to families, children, and…

Saudi Arabian Petrochemical Company (SAPCO), a petrochemicals manufacturer, has decided to make some major internal changes to gain increased market share and continue its success. It has been easy going for some time now, and business has been very good, but in order to take that next step, SAPCO needs to attain the Responsible Care…

A Wolff-Kishner reaction that does not require hydrazine has been developed. The reaction sequence has two steps: formation of a carbomethoxyhydrazone from methyl hydrazinocarboxylate and acetophenone, then decomposition of this intermediate by treatment with potassium hydroxide in triethylene glycol. Purification is by filtration through a plug…

School leaders across the United States face the challenge of creating safe and secure environments across their campuses in a way that helps promote the achievement of schools' educational objectives. To help them meet this challenge, the U.S. Department of Homeland Security's Cybersecurity and Infrastructure Security Agency asked the Homeland…

We live in an age in which the destruction of the environment has become a major concern. However, until recently, environmental problems have not become a major issue for the philosophy of education. The reason for this is that for a very long time the philosophy of education was intimately related to the concept of nature as the foundation and…

Arsenic is a toxic element to which humans are primarily exposed through food and water; it occurs as a result of human activities and naturally from the earth's crust. An experiment was developed for a senior level analytical laboratory utilizing an Inductively Coupled Plasma-Mass Spectrometer (ICP-MS) for the analysis of arsenic in household…

Transition metals play an important role in many biological processes, however, they are also toxic at high concentrations. Therefore, the uptake and efflux of these metals must be tightly regulated by the cell. Bacteria have evolved a variety of pathways and regulatory systems to monitor the presence and concentration of metals in the cellular…

The objective of our program is to foster and facilitate authentic research experiences in middle and high school science courses. We do so by providing students with a complete experience in scientific experimentation and communication. The centerpiece is a set of experiment modules in which students investigate the effects of toxic chemicals on…

Pesticide exposure represents a significant occupational health hazard for farmworkers, and handwashing is one strategy to reduce exposure via the dermal route. After learning about recent research findings regarding the lack of handwashing utilized by North Carolina farmworkers in the field, the North Carolina Farmworker Health Program approached…

Public school facilities primarily serve an educational role, and they also serve a civic role as voting places and emergency shelters. School districts collectively spend tens of billions of dollars each year on facilities construction needs at the nearly 100,000 K-12 public schools nationwide. About half (an estimated 54 percent) of public…
