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…

Nursery growers are one of the largest agricultural users of water. Researchers have been developing new water treatment techniques and technologies for nursery growers to assist in preserving this precious resource, yet adoption within the industry has been limited. Extension professionals need to work closely with nursery growers to encourage…

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…

Promoting collaboration and discourse in asynchronous online courses is challenging; students need something engaging to talk about, a communications medium in which to fluidly discuss it, and a social environment that supports discourse. We designed a fully online introductory geoscience lecture and lab course called Geology Goes Hollywood that…

The comprehension of the reactivity of the elements is an important goal to be achieved in undergraduate courses in inorganic chemistry. Therefore, at Universidade Federal de São Carlos (UFSCar), the B.Sc. in chemistry has a laboratory course dedicated to the chemistry of the elements. However, we have noticed a decrease in students' interest in…

Background: Consuming sugar-sweetened beverages is associated with several chronic health conditions. In the United States, government regulations and behavioral health interventions to reduce the consumption of sugar-sweetened beverages and increase the consumption of healthy beverages have shown limited effectiveness. Differences in motivation…

Working with stories of children's relationships with place and technologies from an early childhood education pedagogical inquiry research project in Melbourne, Australia and Victoria, Canada, this article takes up the concept of "pedagogical intentions" to consider how educators and researchers might cultivate intentional teaching…

This paper tells about the mental model of prospective scholars on the topic of temperature and heat. The purpose of this research is to improve students' mental model by using problem based learning (PBL) model. The number of samples in the study amounted to 72 students with two different classes. The results of the study showed that, (1) the…

"You Live in a Watershed" is a state park exhibit about watersheds. We conducted a two-pronged assessment of learning and attitudes. Study 1 employed a pretest-intervention-posttest design with 30 children visiting the exhibit on a fieldtrip. We found significant increases in knowledge and attitudes. Study 2 was a quasi-experimental…

The purpose of this study is to investigate students' mental models of the marine environment and to further examine how these models are related to their perceptions of marine problems. One hundred twenty-eight ninth grade students from a large harbor city in southern Taiwan completed a survey including a drawing activity and a set of two-tier…

Virtual mobility experiences provide a valuable option to enrich student learning and development from home. However, there is a lack of evidence of how these online experiences are leveraged in STEM and their potential positive effect on students' critical thinking capabilities. This study explores and details the design of a short-term virtual…

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 most challenging global problems of our age involve coupled human--environmental systems within the Food-Energy-Water Nexus. The undergraduate students currently in our classrooms will be tomorrow's global citizens, each of whom must be prepared to understand and reason about these challenges and ultimately make decisions about them in a…

According to the Framework Education Programme for Elementary Education in the Czech Republic, part of Health Education is nutrition and food intake, including the drinking regimen. This paper's objective is to analyse that using the results of two extensive curricular studies performed at the Faculty of Education, Palacký University Olomouc. Both…
