Removing the pollutants from various wastewater is crucial to the environment, ecology, and humans. However, the pollutants are generally removed by chemical decomposition, which not only consumes a lot of energy but also produces carbon emissions. Electrochemical flocculation is effective to extract pollutant molecules and heavy ions from…

If students are asked, "What is the world water crisis?" how would they respond? In the authors precalculus classes, this question is often met with blank stares and students avoiding eye contact. Many students are unaware of the world water crisis--what it is, why it is, or who it affects. Even fewer realize the utility of trigonometry…

A low-cost and easy-to-use water recirculation system for a condenser apparatus was designed and installed in an organic chemistry teaching laboratory. Relying on gravity and a small pump for water circulation, it supplies four stations simultaneously. The water recirculation system works very well with condensers used for distillation and reflux…

We investigated the role of children's conflict monitoring skills in revising an intuitive scientific theory. Children aged 5 to 9 (N = 177; 53% girls, data collected in Germany from 2019-2023) completed computer-based tasks on water displacement, a concept prone to misconceptions. Children predicted which of two objects would displace more water…

Serious games combine education and entertainment to create engaging and effective learning experiences, potentially contributing to science literacy and environmental awareness. This research aims to investigate the effectiveness of a particular serious game, H2OeduK, in educating children aged 10 to 11 years on the urban water cycle.…

Recent studies have reported a growing trend of using student-generated diagrams for assessment in science teaching and research. However, many educators tend to use diagrams to explore students' perceptions of scientists and their work rather than explore conceptual understanding of abstract concepts. In this study, we used diagrams to…

It may be asserted that there is no more effective deterrent to crime than the certainty of detection. Equally true is that there is no surer way to establishing identity than by fingerprints. The detection of fingerprints at the scene of crime is therefore one of the most powerful tools available in casework investigations. However, if the crime…

Purpose: The purpose of this study is to examine the differences in sustainability knowledge, behaviors and attitudes among college students and to estimate the influence of knowledge of sustainability on students' sustainable behaviors. Design/methodology/approach: A cross-sectional online survey was used to collect quantitative data on…

Our study explored current environmental sustainability practices of U.S. camps as well as the motivations and barriers influencing integration of sustainable operational approaches. Using a web survey of camp organizations in Spring 2021, we identified participation in sustainable actions across five broad categories: waste management,…

This paper explains Feeling and Hearing Country as an Australian Indigenous practice whereby water is life, Country is responsive, and Elders generate wisdom for a communicative order of things. The authors ask, as a society of Indigenous people and those no longer Indigenous to place, can we walk together in the task of collectively healing…

Corrosion of metal, especially iron, is a natural electrochemical process that costs billions of dollars every year. Educating college and precollege students, our future STEM professionals, about the chemistry that governs corrosion and its prevention strategies is of paramount importance. In this manuscript, we share a few simple iron…

Nearly a decade ago, the "Framework for K-12 Science Education" argued for the need to intertwine science and engineering practices, disciplinary core ideas, and crosscutting concepts in performance expectations. However, there are few empirical examples for how intertwining three dimensions facilitates learning. In this study, we used a…

This paper materialises the affective emergence of watery assemblages between sea, shark, swimming and British-Bangladeshi Muslim schoolgirls of my PhD research. Watery assemblages pushed further my participant's lived experiences into another layer of 'force field of differentiation' (Alaimo, "Bodily natures: Science, environment, and the…

The inexorable rise in atmospheric carbon dioxide impacts not only global warming but also the acidity of the ocean. Increasing ocean acidity causes a decline in carbonate (as it is protonated), which in turn will negatively impact the ability of calcifying marine organisms to build their calcium carbonate shells. A simple set of equilibrium…

Water safety skills are vital for the safety and well-being of all individuals but especially for individuals with autism spectrum disorder (ASD). Research regarding on-deck water safety behaviors and water safety skills for individuals with ASD levels 2 and 3 is limited. Therefore, the purpose of this study was to evaluate the effects of behavior…
