Understanding the dynamic relationships of the entities that have the most impact on an organization - or that the organization impacts the most - is at the core of stakeholder management approaches. In this article, we present an experiential exercise that provides a creative practical, low-overhead, discussion-oriented classroom activity 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…

Water electrolysis, a well-known and simple experiment, confirms that a water molecule comprises hydrogen and oxygen atoms. In this experiment, hydroxide or hydrogen ions generated from each electrode were identified using an indicator based on the assumption that electrodes, electrolytes, and indicators do not participate in the water…

The automated water filtration design challenge integrates computer programming and basic electronics concepts through the SIMILAR systems engineering design process. The SIMILAR systems design process is to state the problem, investigate alternatives, model the system, integrate the system, launch the system, assess performance, and reevaluate…

Surfing has a great educational potential. This paper shows Physical Education (PE) teachers how to introduce surfing in their lessons although they are far from the coast and the waves. Our intention is to show its implementation through several stages that will progressively bring students closer to practicing surfing. For that purpose, we…

Groundwater contamination is a serious environmental problem, given that all living things depend on this essential resource. Groundwater represents less than 1% of all water found on Earth, but nearly 90% of the freshwater used comes from groundwater (USGS 2016). The problem-based activity described in this article actively engages students in…

The anomalous thermal expansion of water in the 0 °C-4 °C range is extremely important to life on Earth, but it is normally not presented experimentally in educational settings. This paper presents a simple experiment to explore the anomalous thermal expansion of water in the 0 °C-4 °C range and the heat exchange processes in natural bodies of…

The design and operation of the vapor-absorption refrigerator (VAR) are described using the principles and tools typically covered in upper-division undergraduate physical chemistry courses. The objective is to enable students to understand in detail how this device works and how it compares with more typical vapor-compression refrigerators.…

Water is a meaningful context for children to engage in inquiry, and to acquire and use science and engineering practices, such as developing spatial thinking and early concepts of water dynamics. This book shows teachers how to provide children with opportunities to engineer water movement through pouring and filling containers of various kinds…

This article describes how fifth grade students participated in a place-based environmental education initiative in West Michigan that supports teachers who want to involve their students in citizen science by protecting local water resources. Every year, Groundswell works with about 100 teachers at 30 schools to engage students in citizen science…

The debate over the mechanisms responsible for the flow rates of simple tube siphons has received much attention in the physics education and general physics literature in the past decade. Particularly with regard to the driving mechanism for water siphons, some suggested explanations emphasize contributions, or lack thereof, from the atmospheric…

This laboratory experiment introduces students to an important reaction in biomass valorization and allows them to gain a practical understanding of green chemistry. Acid-catalyzed dehydration reactions of fructose to 5-hydroxymethylfurfural and thus humins were performed both with and without aqueous solvent, along with two different catalysts…

The non-SI unit sverdrup, named to honor Norwegian oceanographer and meteorologist Harald Ulrik Sverdrup (1888-1957), is adopted for quantifying large-scale volume transport by oceanographers, meteorologists, and atmospheric physicists. The sverdrup is used to appraise the volumetric rate of evaporation, precipitation, runoff, transport of ocean…

Sustainability is emerging as a prominent curricular initiative at the undergraduate level, and as a result, involving students in real-world problems in the classroom and laboratory is an important goal. The specific problem of a dwindling supply of clean and safe drinking water is also of utmost importance and relevance. This general chemistry…

The authors describe their resources for raising awareness and encouraging positive water behaviours among young children. The DRY (Drought Risk and You) project brought together a multidisciplinary team to create a research-informed storybook and teachers' notes for 7- to 11-year-olds. This article takes a brief look at the book and reflects on…
