In the current study, an engineering design-based STEM activity was designed and implemented for 5th graders. The current activity is expected to provide guidance and perspective to teachers (practitioners) in designing and implementing an activity based on design-based learning, STEM activity, and engineering design process (EDP). At the same…

A key part of the practice of chemistry is the analysis of chemical composition, including through gravimetric analysis and spectrophotometry. However, the complexity of doing multiple calculations to obtain analytical evidence, such as that required to determine an empirical formula, presents a challenge if such analytical methods are to be…

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…

This is a study conducted on the works in the field of children's literature by Ferda Izbudak Akinci who has achieved important goals and created works in the field of children's literature. It has become necessary to conduct the study due to the fact that the author and her works had not been studied with a comprehensive analysis, and the element…

This is a study of water and beverages consumed during pregnancy by mothers of children with autism. Materials included vials for water samples and a survey to describe the water and beverages. Samples were tested for sulfate and surveys evaluated for average daily levels. Results were stratified for selected regions of the United States. Areas…

Despite the essentiality of freshwater to all life on the planet, the populous has inadequate understandings of water. Formal education plays a key role in shaping how individuals and communities make sense of water, its accessibility, management, consumption, and hazards. This article seeks to bring attention to the infuence of cultural framings…

The Griess assay is widely used by regulation agencies as an official method for nitrite quantification in water and food samples. In Brazil, the official method, which has been used to determine nitrite in food, was described by Instituto Adolfo Lutz (283/IV) in 1984. It uses 8 mL of reactants and provides 50 mL (reactants plus sample) of waste…

Siphons have been used since ancient times to transport water between two points over an intervening barrier higher than the water source. This paper describes a practical application of a siphon to provide fresh water to a remote island community in the Solomon Islands. The siphon was constructed from 25 mm diameter blue line polyethylene pipe.…

Space-related activities remain a fertile environment for classroom applications of chemistry through both traditional lecture styles and through collaborative learning projects. With the resurgence of lunar exploration and the expansion of the commercial space sector, serious scholarship, planning, and resources have been focused on extracting…

This study provided practical advice for energy and water conservation message design by examining the role of choice provision (a message feature), message elaboration (a situational factor), and issue involvement (an individual factor) on intentions to conserve. The data were collected through an online survey experiment (N = 857). Across…

A one-pot regio- and stereoselective synthesis of a dipyrromethane and a bis(indolyl)methane based on two consecutive reactions of nitrosoalkenes with pyrrole or indole, respectively, is described as an experiment to be carried out by upper-division undergraduate students in a laboratory classroom. Importantly, the ability of electrophilic…

Sound is an interesting topic for physics lessons at all ages. However, it is difficult to illustrate this ubiquitous phenomenon and many models do not adequately represent the properties of sound and thus promote unwanted conceptions. The experiment presented here avoids this by visualising sound itself with the help of the schlieren technique.…

Tungsten oxide semiconductors are used to photooxidize water. Students prepare WO3, CuWO4, and mixed composition thin film photoanodes. The syntheses are simple, allowing for the quick production of a range of materials. Photoanodes are tested in a photoelectrochemical cell assembled from common equipment, allowing for the direct comparison of…

This article shares a curriculum developed by preservice art teachers to encourage 9th-grade art education students to learn and create together, making decorative rain barrels to help their community's future and discover how artmaking can help provide sustainable ways to address ecological challenges related to their local environment. A…

This paper unfolds the artful and pedagogical potentials of engaging in a simultaneous practice of walking and artmaking in different locations, along bodies of water, and together-apart. Through introducing the term co-living inquiry as a thread between action research and a/r/tography, we suggest how the notion of walking with as both action and…
