Addressing food, energy, and water issues through a systems approach is essential for Native American communities, where climate change, natural disasters, and pandemics further strain access to these vital resources. Tribal communities experience a disproportionate impact from these global crises, which heightens and exposes existing…

A previous study mentioned that students' action responses towards water pollution are incongruent with the training they received in schools. Conducting a course of two weeks with elementary students (N = 22) aged 9-10 in Hong Kong, the study aims to connect primary students' perceptions of the causes, consequences and responsive actions on water…

The development of students' argumentation competence is one of the major aims of science education and everyday problems, such as decisions on the consumption of tap water or bottled water, which may be suitable contexts to encourage it. Citizens consider of interest certain controversies associated with the bottled water consumption as an…

Water sciences education is paramount to sustainable groundwater resource management, especially of drinking water, but misunderstandings about groundwater among non-experts remain widespread. Groundwater residence is an especially challenging concept to learn because it is not directly visible in typical circumstances. The present study uses a…

This paper discusses the use of an estuary monitoring toolkit "Nga Waihotanga Iho" as a central part of a Maori-centred education project undertaken by Kaipara hapu (sub-tribe), Te Uri O Hau, in Northland, New Zealand. The toolkit was designed by New Zealand's National Institute for Water and Atmospheric Research (NIWA). In this project,…

Water analysis is an excellent interdisciplinary topic for project-based learning. An undergraduate course was designed to engage the senior undergraduate chemistry students in a real-life experience. In this course, students developed methodologies based on published American Society for Testing and Materials (ASTM) methods for the measurement of…

Background: We investigate the nature of planning the canoeing of rapids and its reasoning processes, while at the same time advancing a syncretic approach to cognitive and situative theories of learning. Building upon the work of Lucy Suchman, we examine how canoers plan to run rapids and how plans serve as resources for action. Methods: In…

Music cannot be separated from its historical, geographical, and cultural context; therefore, it is important that students be taught music from a variety of genres, cultures, and historical periods relevant to the music to which they are introduced. In this article, I introduce an interdisciplinary approach through contextualization of the…

The contamination of wastewater with metals and the use of biotechnologies to remove them is commonly discussed in theoretical biology, microbiology and biotechnology classes aimed at undergraduate students. This work introduces an easy, economical and safe practical laboratory class related to this topic. The practice consists in performing batch…

A glass filled with carbon dioxide gas upside down on a plate of water constitutes an excellent demonstration of the solubility of gases. If the water level on the plate is maintained the CO[subscript 2] will slowly dissolve and the column of water will rise inside the glass, without quite reaching the ceiling, before an opposite process sets in:…

The long and complex history to define the composition of water as H[subscript 2]O is summarized. This case study could be useful not only to introduce the history of chemistry in the classroom but also to teach the basic tenets of the nature of science (NOS). Water has been present in several turning points in the history of chemistry such as the…

The non-SI unit sverdrup, named to honor Norwegian oceanographer and meteorologist Harald Ulrik Sverdrup (1888-1957), is adopted for quantifying large-scale volume transport by oceanographers, meteorologists, and atmospheric physicists. The sverdrup is used to appraise the volumetric rate of evaporation, precipitation, runoff, transport of ocean…

One of the most popular demonstration experiments pertaining to Bernoulli's principle is the production of a water spray by using a vertical plastic straw immersed in a glass of water and a horizontal straw to blow air towards the top edge of the vertical one. A more general version of this phenomenon, appearing also in school physics problems, is…

There is a consensus that the content of education for sustainability should be integrated into the curriculum, engaging students in activities that promote awareness and practice of sustainability. To achieve this goal, it is essential to adopt a student-centered approach that involves creative, stimulating, and challenging activities. This…

Purpose: This study explores whether farmers across England believe that advice on diffuse water pollution from agriculture (DWPA) which is currently provided for free at the point of delivery is credible, relevant, and legitimate ('CRELE') enough to justify paying towards. Methodology: A mixed-methods study consisting of an online questionnaire…
