In urbanized areas, incorporating residents' concerns and priorities into the stormwater management debate has focused on adults rather than youth. This study used Photovoice, a tool that includes photographs taken by youth, to uncover youth concerns and perceptions about their local watersheds. This study consisted of a comparative study of two…

Many of us are familiar with the demonstration of boiling water in a paper cup held over a candle or a Bunsen burner; the ignition temperature of paper is above the temperature of 100°C at which water boils under standard conditions. A more dramatic demonstration is melting tin held in a playing card. This illustration is from Tissandier's book on…

Measurement of plasma osmolality (P[subscript osm]) remains popular for assessing hydration status in exercise science. However, a controlled reliability assessment of micro-osmometry using small sample volumes to measure Posm remains to be performed. This study aimed to examine the reliability of a cryoscopic micro-osmometer requiring 15-µL…

This paper explains and analyses a virtual gamification experience developed by a teaching group from the University of Catania (Italy) and the University of Cordoba (Spain). A competition based on professional tasks about hydrological planning was implemented in two subjects on Hydrological Sciences. The teaching experience was designed to…

Purpose: The market of bottled water is one of the largest in the world. Paradoxically, the consumption of water in plastic bottles is highest in countries rich in the potable tap water of excellent quality. This paper aims to gain a better understanding of the factors that foster or hinder the intention to use refillable water bottles by…

Teaching the fundamentals of chemical kinetics on the college level is challenging to teachers and students alike due to its abstract nature of concepts and limited connection with real context applications. This study consisted of two phases starting with designing a chemistry education for the sustainable development-based learning environment…

Micellar catalysis has become an important aspect of the chemical industry's effort to "go green". However, this chemistry has yet to be fully explored in educational settings such as second-year organic chemistry laboratories. Reported herein is a discovery-based nucleophilic aromatic substitution experiment that introduces chemistry…

This paper describes two studies comparing students' explanations of an oxidation-reduction reaction after viewing the chemical demonstration and one of two different particulate-level computer animations. In the first study, the two animations differed primarily in the complexity of the visual images. Students viewing the more simplified…

The present study reports an empirical investigation into concept formation of young children. Based on interviews conducted before and after participating in a playfully enacted chemistry lesson at a culture center, it is analyzed how 6-year-old children conceptualize water, molecule, and chemistry. Theoretically, the study is informed by…

Urinary schistosomiasis is endemic in sub-Saharan Africa, including Sudan, the risk for schistosomiasis is widespread, especially in the major irrigation systems in the Gezira area between the Blue and White Nile Rivers and both "Schistosoma mansoni" and "Schistosoma hematobium" are endemic. A cross sectional descriptive study…

Developing scientific literacy about water systems is critical for K-12 students. However, even with opportunities to build knowledge about the hydrosphere in elementary classrooms, early learners may struggle to understand the water cycle (Forbes et al., [Forbes, C. T., 2015]; Gunckel et al., [Gunckel, K. L., 2012]; Zangori et al., [Forbes, C.…

Purpose: This paper aims to investigate the knowledge, attitude and behaviour of foundation chemistry learners concerning the sustainable development concept. Design/methodology/approach: Qualitative and quantitative studies were conducted. Atlas.ti software was used to analyse the chemistry curriculum based on selected themes and sub-themes. A…

Two South African professors and two U.S. professors investigate the need for environmental education in preparing U.S.-based preservice teachers for a South African study abroad trip.

Environmental health issues are major risk factors in the global burden of disease. This paper therefore focuses on the most important link between health and environment. It discusses the most important environmental threats to health in the 21st Century especially in the low and middle income countries. It reviews the burden of disease from…

The current study aims to investigate the mental models of primary school students about marine environments and how variables such as gender, grade level, and city of residence affect their mental models. To this end, 100 students were selected from each of the four grade levels of primary education in Turkey; thus, a total of 400 students…
