This study aims at investigating students' awareness of green chemistry principles (GCPs) which are infused in two context-based projects that are related to socio-scientific issues, namely climate change and materials' recycling. At first, content analysis of the projects' activities showed the infusion of four GCPs. Subsequently, the students'…

Children spend as much as ten hours per day, five days a week in childcare centers and preschools. In providing healthy environments, these facilities deal with a variety of pest and pesticide issues influenced by their geographic location, local environment, and pesticide regulations. Some rely extensively on pesticides while others use…

The most important indicator of meaningful learning in science education is that the students learn and often encounter in their daily life in the description. To be able to implement this, students need to be a good science literate. This study was carried out in order to reveal to what extent the teacher candidates can explain the relationship…

This paper describes a method for determination of trihalomethanes (THMs) in drinking water via solid-phase microextraction (SPME) GC/MS as a means to develop and improve student understanding of the use of GC/MS for qualitative and quantitative analysis. In the classroom, students are introduced to SPME, GC/MS instrumentation, and the use of MS…

Due to the unique and advantageous physiochemical properties of nanoparticles, they have been increasingly incorporated into consumer products and emerging technologies. The manufacture, wear and tear of use, and disposal of these nano-enabled products will likely result in the release of nanoparticles into the environment. Unfortunately,…

Purpose: Universities are an example of institutions that aggregate people around work/study who consume water, energy and produce waste daily in their activities, generating an impact on the environment. The purpose of this study is to determine the quantity, composition and recycling potential of waste generated at the Faculdade UnB Planaltina…

The many negative effects that deficient building conditions have on educational quality have long been ignored. Until school systems can ensure all students have access to school buildings that are healthy, safe, comfortable, and dry, we cannot hope to adequately protect the well-being of students and staff, recruit and retain teachers, or…

Exothermic reactions can present safety hazards and there is a recognized need for reaction safety education at the undergraduate level. We present an experiment that illustrates the pitfall of direct scale-up of an exothermic reaction that can lead to thermal runaway. The iodide-catalyzed hydrogen peroxide decomposition reaction yields…

The university traditionally has been the foundation for young adults' professional development, yet the proclivity toward safety culture has garnered less focus in higher education than in the workforce. A survey of faculty at a medium-sized, research-active, private institution revealed specific areas of policy noncompliance as well as specific…

Long before closures due to the coronavirus pandemic, many Pennsylvania schools faced a different health crisis: unsafe facilities. Crumbling buildings, asbestos, lead, and other school facility health and safety risks plague many schools across Pennsylvania, particularly in low-income districts and those that enroll a high percentage of Black and…

To assist Extension professionals working in Texas's Little River Watershed with efforts to educate landowners about reducing amounts of bacteria there, we assessed motivations for and barriers to landowners' adopting best management practices (BMPs). We surveyed 275 landowners in the watershed. Respondents were at least somewhat familiar with…

Lead poisoning harms brain and nervous system development and is most detrimental to children resulting in, among other things, reduced attention span, learning disabilities, higher high school dropout rates and delinquency, and higher likelihood of violent crime in adulthood. One major source of lead poisoning in Wisconsin is old housing stock.…

We demonstrate here a novel laboratory experiment for the synthesis of gold nanoparticles (AuNPs) by using a low energy gold-sputtering method together with a modern, green, and biofriendly deep eutectic solvent (DES). The strategy is straightforward, economical, ecofriendly, rapid, and clean. It yields uniform AuNPs of 5 nm in diameter with high…

In 2018 the Gulf coast of Florida suffered extensive damage from harmful algal blooms (HABs), from as far north as Clearwater Beach south to Naples. The bloom lasted nearly a year, picking up in intensity during the late summer months. HABs occur when conditions such as reduced salinity, higher water temperatures, light saturation, and currents…

A summer workshop was offered to inner-city high school students to explore the sustainability of their consumer choices using a systems thinking model. Students learned about related environmental or health issues due to the manufacturing, use, or disposal of common household products. Then, in the laboratory, they performed experiments to…
