Agriculture's negative effect on water quality has become increasingly well documented. Farmers have a range of conservation practices available, yet rate of adoption is not optimal. Extension and other agricultural stakeholders play a key role in promotion of conservation practice adoption. We used survey data to examine relationships between…

This relatively rare thermometer has a rather unusual display: lower temperatures are located at the top of the scale, higher ones at the bottom. A sphere on a chain floats in a suitable liquid, sinking at high temperatures when the density of the liquid decreases and rising in the increased density at low temperatures. With reasonable effort and…

This research explored the power of dominant partnerships in promoting community development. Two local communities sited in a coastal West African town, recorded notable transformation as a result of their members' long-standing interaction with a famous close by higher education institution. With a sample of three hundred and seventy-two…

Recent national reforms focus on learning disciplinary core ideas through engaging in science and engineering practices. These reforms also call for students and teachers to use crosscutting concepts (CCCs), or analytical lenses, that support scientific sensemaking and connections across disciplines. The "Framework for K-12 Science…

Faculty in the Chemistry and Environmental Science programs at St. Mary's University in San Antonio, Texas, collaborated to develop an undergraduate course in Field-Based Environmental Chemistry. The course was developed and implemented as a 2-semester, 1-semester, and online, synchronous course offered during the 2020/21 COVID-19 pandemic. As…

Science educators demonstrated that students' framings -- their expectations of what is going on -- influence how they participate, and what science knowledge they reveal, in clinical interviews. This paper complements research that explores how interviewers are likely to affect student framings, by exploring how subtler interactions can lead…

The Suzuki-Miyaura cross-coupling reaction, which is one of the most important methods for C-C bond formation in modern organic synthesis, exhibits broad functional group compatibility. A Suzuki-Miyaura cross-coupling protocol is reported that is suitable for demonstrating this compatibility in undergraduate laboratories. In this reaction, two…

This paper describes environmental systems games developed for energy and water resource use designed to be adaptable from high school to undergraduate use. Two of the games are computer simulations with adjustable levels of difficulty that can be done in a computer lab or as a homework assignment. The third is a peer-to-peer roleplayer game…

This article will investigate the philosophy of science of Roy Bhaskar (1944-2014) as a coherent basis for environmental education. The work of Bhaskar serves as an in-depth approach to understanding how to apply critical realism (the critical and the realist) to matters such as environmental education, because he concretely theorises the…

Several problems such as the deterioration in water regime, climate's getting harsh, desertification and the decrease in agricultural productivity have been experienced in and around Lake Avlan which was dried in 1970's entirely for the purpose of opening new cultivation areas. Upon the deterioration, the gates of the regulators were closed by the…

This study aims to design a mechanism with which the density of any solid or liquid can be determined without measuring its mass and volume in order to help students comprehend the concept of density more easily. The "solidensimeter" comprises of two scaled and nested glass containers (graduated cylinder or beaker) and sufficient water.…

Tourism is important because it can revive economically a community around tourist attractions. North Sumatra Province, which includes Medan, shows great potential for the development of marine tourism. However, it is not run optimally. Moreover, poor quality infrastructure and human resources are also a threat to marine tourism in Indonesia. This…

A low-cost alternative to the typical scientific laboratory water bath or a hot plate stirrer water bath is proposed. Readily available immersion circulators have been developed for sous vide cooking. These precision cookers are designed to maintain water at an exact temperature and thus are well-suited for the similar laboratory requirements of a…

Undergraduates can become effective agents of environmental outreach when challenged to produce evidence-based messages to inform the public about local environmental issues. We recount our experience partnering our undergraduate students with community organizations dedicated to water stewardship to create a "Pedal and Paddle Pollution…

The interaction between water and surfaces is observed in our daily lives and is used in laboratories to study materials properties, such as interfacial tension. Making the connection between fundamental scientific phenomena and everyday observations is a powerful method of highlighting the importance and relevance of science to the K-12…
