This study reviewed the evolving capabilities of hydro-drones, Unmanned Aerial Vehicles (UAVs) which are used for spraying and cleaning with a focus on water management, and it revealed that the unique capabilities of hydro-drones offered the potential to create challenging and rewarding education and training programs, designed to provide new or…

Water is essential for life. The brain, heart, kidneys, and lungs require continued hydration to function, and our bodies need water for digestion, nutrient absorption, blood distribution, and so much more. While water comprises around 60% of the adult body, 75% of infants' bodies are water. Children also drink more water per pound of body weight…

Local leaders are essential for helping Michigan achieve its 30-year water strategy goals. The Michigan Water School is an Extension nonformal educational program to address the knowledge gap of local leaders. We evaluated programs conducted from 2017 to 2019. Results revealed program outcomes in knowledge, attitudes, perceptions of criticalness…

Water is critical to our health and well-being, yet one in three people do not have access to safe drinking water. Earth's water is threatened by pollution, deforestation, urban growth, and climate changes. This article describes a unit for kindergarten children called The Water We Drink.

We use novel information about fixture-specific water lead levels (WLLs) in Portland, Oregon schools to explore inequalities in students' potential for exposure to lead in drinking water at school. We find that Black and Hispanic students were in classrooms with higher WLLs than white students primarily because they attended different schools. The…

With water shortage and increasing demand for water, education may have an important role in promoting the sustainable management of water resources. Educational curricula are the key resources used by teachers for students' teaching and training purposes. This study assessed water culture and water education-related criteria and standards in…

This article recounts our field experience and research in TfD in the Ofabo community, Kogi State, Nigeria. Through socially engaged performance and participant observation, this study finds that the poor state of drinking water in the Ofabo community results from government negligence, inadequate awareness, and the inactivity of community…

The incorporation of interdisciplinary education, a topic of significant global interest, is increasingly being recognized as a key aspect of educational innovation in Vietnam. This recognition extends to several fields, including STEM (Science, Technology, Engineering, and Mathematics) education. This research aims to design and implement a STEM…

Silver and its compounds have been widely used in experimental teaching, industrial production, and other fields. In these processes, a large amount of wastewater containing silver is usually produced, which might contribute to environmental pollution. Therefore, recycling silver from wastewater not only has good economic value but also meets the…

Coagulation is an important process in the context of water purification; and the seed protein of the moringa tree ("Moringa oleifera") is a remarkably effective coagulant. The laboratory course described here is designed to provide high-school students with a stepwise, hands-on experience in investigating the protein-rich coagulant…

Common wisdom holds that ATP hydrolysis is spontaneous because of the weakness of its phosphoanhydride bonds, electrostatic repulsion within the polyanionic ATP[superscript 4]-molecule, and resonance stabilization of the inorganic phosphate and ADP products. By examining the pH-dependence of the hydrolysis Gibbs free energy, we show that in fact,…

We present an example of one of the modelling projects we assign to students in our differential equations classes. Students are asked to determine how to run a cost-efficient hot water heating system. We consider a cylindrical tank filled with water and heated by a heating element immersed in it. Together with students we discuss physical laws…

A functionalized fiber (PAN[subscript ADMAP]F) was synthesized by immobilizing "N,N'"-dimethyl-"N"-(4-pyridinyl)-1,3-propanediamine (ADMAP, a DMAP analogue) onto the surface of polyacrylonitrile fibers (PANF). The structure and morphology of the functionalized fibers were characterized by Fourier transform infrared…

The statics of fluids may seem simple at first but often poses problems for students when it comes to applying it to concrete cases. Despite its relatively simple laws, some subtleties, mainly related to the elastic characteristics of a fluid, must be noted. This elasticity allows the pressure exerted in a part of the fluid to propagate in its…

A classical mechanical structure with an internal degree of freedom is shown to reflect off a potential well. Such behavior is impossible for point-like or rigid classical particles. This numerical study provides insight for students studying internal energy and degrees of freedom.
