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…

Hydrogen production from electrochemical water splitting via hydrogen evolution reaction (HER) powered by sustainable energy has been recognized as one of the most promising alternatives to traditional fossil fuels. To integrate the fundamental knowledge of chemistry, electrochemistry, and materials science with practical application and…

Science and society are inseparably linked, shaping each other in ways that define our world, emphasizing the need to teach science for empowering students capable of taking meaningful action toward building a sustainable and just society. Developing sustainability competencies in students is an important step toward this goal, with controversial…

Virtual mobility experiences provide a valuable option to enrich student learning and development from home. However, there is a lack of evidence of how these online experiences are leveraged in STEM and their potential positive effect on students' critical thinking capabilities. This study explores and details the design of a short-term virtual…

Household water treatments (HWT) can help provide clean water to millions of people worldwide who do not have access to safe water. This article describes four common HWT used in developing countries and the pertinent chemistry involved. The intent of this article is to inform both high school and college chemical educators and chemistry students…

We discuss an experiment on wind energy performed with home-made apparatus. The experiment reproduces a laboratory windmill, which can pump water from a lower level to a higher one. By measuring the gain of the gravitational potential energy of the pumped water, one can determine the power extracted from the wind. The activity was carried out with…

Geology is increasingly involved in the planning and implementation of community development projects throughout the globe. A partnership among the Water For Life organization, Wheaton College in Illinois, and the village of Tushile in Kosovo during the past few years has proven to be successful in potentially sustainable improvements, including…

One activity that gets children thinking about how electricity is made involves exploring hydro (water) power. Water has been used as a source of energy for thousands of years for mechanical purposes such as grinding corn, bellows for furnaces or sawmills for cutting wood or slate. For about a century hydro power has been producing electricity…

Instructional strategies determine the approaches an educator may take to achieve learning objectives. Research has shown that sets of strategies or instructional models anchored on social constructivist learning theories were found to be effective in enhancing active participation. It is particularly influential and meaningful in many areas of…
