Insufficient knowledge of chemical hazards can cause unsafe behaviors, diseases, and accidents in the laboratory, hence educational interventions are significant. Due to its unique qualities, distance learning via educational applications has grown dramatically. This study aimed to determine the efficacy of a safety training intervention via…

The benzoin condensation of benzaldehyde is a staple of the undergraduate organic chemistry laboratory, introducing the current topic of nucleophilic carbene organocatalysis. Our procedure makes notable improvements to current practice, including the elimination of solvent waste and an "18-fold reduction of reaction time." We have…

Environmentally overburdened communities need information and resources to cope with hazards. We describe, and use a case study to depict, a participatory process of engaging Detroit stakeholders with academic researchers in the co-production of environmental health communication tools to enhance their capacity to address the unjust conditions.…

In this laboratory activity, students were tasked with determining the heat of combustion for each of three common sugar substitutes: saccharin, aspartame, and sucralose. The heats of combustion were determined via three different methods: bomb calorimetry, heats of formation derived from semiempirical calculations, and tabulated average bond…

Early care and education (ECE) environments influence children's lifelong health behaviors, growth, and development. Although the number of interventions to improve health in ECE environments is increasing, few have been designed for and tested in family child care homes (FCCHs). This study reports the process evaluation of two interventions to…

Lead exposure has been linked to neurological, reproductive, and developmental effects, and approximately 3.5% of Chicago children under the age of 3 years have elevated blood lead levels. The aim of this research was to provide outreach opportunities to address the issue of lead exposure in water and soil. A series of seven community-based health…

We created a 2-week, dual-module summer course introducing high school students to environmental toxicology by teaching them quantitative polymerase chain reaction (qPCR) as a way to quantify gene expression of chemical defense proteins in response to exposure to environmental pollutants. During the course, students are guided through the various…

This study aimed to investigate the effect of the analytical chemistry laboratory (ACL) course, designed, and conducted according to the flipped learning approach (FL) on prospective science teachers' (PSTs) meaningful understanding and interpretation of knowledge in the context of the environment. Seventy-three second grade PSTs participated in…

Petroleum products are very flammable and can ignite at extremely low temperatures if exposed to an open flame source or not handled appropriately. Individuals who handle petroleum products in the petroleum industry and fuelling stations are known as "petrol station attendants". The study was a descriptive cross-sectional study carried…

It is widely known that systematically developed training manuals can be used to improve knowledge and practical skills and promote positive attitude of trainees. This research thus aimed to develop a training manual to help reduce the use of pesticides by para rubber farmers in Nonkheng Sub-district, So Phisai District, Bueng Khan Province,…

This study compared reported chemistry anxiety in an undergraduate chemistry course between online and classroom students. Results indicated slightly higher levels of anxiety for online students although findings were not statistically significant. However, activities resulting in high anxiety for both groups were identified. Gender was identified…

A laboratory experiment to study the effect of soil amendments in the bioremediation of polluted soils is described. Students extracted and measured 0.01 M CaCl[subscript 2]-soluble Cd, EDTA-soluble Cd, and DTPA-soluble Cd concentrations in contaminated soils, treated with a liming material (mussel shell), and/or with an organic amendment (pine…

Modern society is under increasing threats of natural and technological disasters, which involve complex interactions among science, technology and social structures. Although a scientific understanding of disasters is an immediate global issue, there is limited discussion about how disasters can relate to science education. To address this gap,…

Background: Faculty in nursing and history at Creighton University directed two service-learning courses on the history and public health implications of lead (Pb) exposure in Omaha, NE. As part of their service requirements, students conducted or observed blood lead screenings in area schools and reflected on these shared experiences in…

With the advancements in broad-spectrum sunscreens and the recent bans on benzene-based sunscreens due to their environmental toxicity, there has been a push toward broad-spectrum sunscreens containing in organic active ingredients. In this study, a procedure was developed to analyze the particle size and size distribution of inorganic active…
