"Copper to Silver to Gold: The Alchemist's Dream" is an experimental demonstration performed in many schools that involves Zn plating on a Cu coupon to induce brass plating. In this study, a novel method to achieve uniform plating is proposed using a 2.0mol/L ZnCl[subscript 2] aqueous solution, sodium dodecyl sulfate, and Al foil. This…

The purpose of this work is, before the mission, training of personnel searching for explosives with metallic mine detectors for their operations in the battlefield and gaining experience by searching for explosives in a virtual environment. In this context, a search model was created by determining the factors affecting the search for explosives…

This paper presents a history of process safety education and the results of a Spring 2023 survey of US and Canadian departments. The number of departments with process safety education throughout the curriculum and those with a required process safety course both continue to increase. Lower-level learning outcomes are expected in departments…

This study employs the Experiential Learning Theory framework to investigate students' use of a wildfire simulation. We analyzed log files automatically generated by middle and high school students (n = 1515) as they used a wildfire simulation and answered associated prompts in three simulation-based tasks. We first analyzed students' log files to…

Iron is needed for normal development in adolescence. Exposure to individual environmental metals (e.g., lead) has been associated with altered iron status in adolescence, but little is known about the cumulative associations of multiple metals with Fe status. We used data from the 2017-2018 National Health and Nutrition Examination Survey…

The American Chemical Society advocates a shift from rule-based to risk-based safety education for chemistry graduates, emphasizing meaningful student engagement in the risk assessment process for laboratory work. To implement this paradigm shift, we introduced RAMP (Recognize Hazards, Assess Risk, Minimize Risk, and Prevent Emergencies)-based…

Educational robotics (ER) has the potential to be a novel approach to teaching geohazards such as earthquakes at the college level. ER, which provides learners with problem-solving settings, requires proficiency in content knowledge and practical application to address ill-defined problems, challenging learners to master problem-solving…

The dangers of organic dye pollutants and environmental pollution improvement through photocatalytic degradation are important courses in applied chemistry programs in universities. Zinc oxide (ZnO)-based nanomaterials are potent catalytic agents against organic dyes, but few experiments are available for students to understand their role and…

The aseptic technique is essential for minimizing contamination in cell and tissue culture. However, biomedical science undergraduates in Universiti Putra Malaysia face challenges in acquiring hands-on learning experience on proper aseptic techniques due to inadequate facilities, which decreases learning interest and efficiency. To address this,…

A variety of strategies have been introduced to tackle the issue of laboratory safety in academic settings. These strategies include innovative educational tools as students transition from the classroom into the laboratory, the introduction of policies designed to protect the researchers in the laboratory environment, and the creation of teams of…

The discovery of frog abnormalities by students on a school field trip in 1995 sparked hundreds of scientific studies in search of the cause of abnormality. This Socio-Scientific Issue has been used as an inquiry-based learning exercise for training in the practice of science, but it is also well-suited to teaching the nature of science. Our goal…

Designing safer chemicals is an integral part of green chemistry that supports good health and well-being. The teaching of molecule design through relevant courses has important implications for the education of sustainable chemists. In these courses, training in toxicology and hazard assessment is essential for students to study benign chemical…

It is important for children to learn safety skills, especially involving dangerous stimuli such as medicine that can be found in almost every household. This study examined a generalization-enhanced behavioral skills training package to teach children with autism poison safety skills. Three children ages 4- to 10-years-old received generalization…

Academic institutions are faced with the complex problem of accurately determining the hazards associated with a proposed or ongoing project. For many reasons, compressed gas safety can be a significant challenge at universities, especially those that involve research using many uncommon materials. This article is a call to action for implementing…

TNT is both toxic and explosive, and therefore, the detection of TNT represents an environmental concern and a security concern. Dogs are often used for detection, but other methods are needed. This laboratory investigates a ruthenium bipyridine ([Ru(bpy)[subscript 3]][superscript 2+]) luminescence-based trinitrotoluene (TNT) sensor. Students will…
