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…

This paper proposes an experiment in which students build microdevices for conveniently electrolyzing water and use image recognition and processing technology to measure the volume of gas generated during the reaction in a noncontact way. Taking advantage of three ratio relationships between (i) gas volume and the area of bubbles, (ii) the…

Adsorption of methylene blue and malachite green was carried out using "Luffa cylindrica" sponges as adsorbing material. We provide a very illustrative exercise about the use of common natural materials requiring little preparation to solve environmental tasks in a routine laboratory situation such as using dyes. In addition, the…

A new laboratory experiment investigating the ternary phase equilibrium of water-propan-2-ol-sodium chloride with one-, two-, and three-phase regions has been developed. Observations of the type and number of phases of a series of mixtures of the three components were made, and the results are then used in a systematic way to more finely choose…

The aim of the study was to investigate the effect of the Common Knowledge Construction Model (CKCM) lesson sequence on grade 7 students' conceptual understanding of the "water pollution" topic. Within a pre-experimental (one group pre-test/post-test) research design, this study was conducted with 25 (12 females and 13 males) grade 7…

Due to global water consumption and an intensification of the resulting consequences there is a need for education regarding sustainable water consumption. Regarding Education for Sustainable Development, the ongoing water use of the industrialized countries needs to be discussed in the classrooms. Therefore, the aim of this paper is to present…
