Water is one of Earth's fundamental natural systems. It is crucial to foster water literacy in today's global citizens, particularly through formal education. The purpose of this research, in parallel with a study focused on human dimensions of water systems (Mostacedo-Marasovic et al., in press), is to examine water-related K-12 standards for…

Topics associated with the chemical sciences form a significant part of the curriculum in science at the primary school level in the U.K. In this methodology paper, we demonstrate how a wide range of research articles associated with the chemical sciences can be disseminated to an elementary school audience and how children can carry out…

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.…

This ethnographic research examines how children enact developing understandings in science through multiple interactions. Grounded in sociocultural theoretical frameworks, we consider learning to be a social, cultural practice, with understandings as co-constructed between participants through talk and in interactions. With these underpinning…

Visual representations, including photographs, sketches and schematic diagrams, are a valuable yet often neglected aspect of textbooks. Visual means of communication are particularly helpful in introducing abstract concepts in science. For effective communication, visuals and text need to be appropriately integrated within the textbook. This study…

The decomposition of water by electricity, and the voltaic pile as a means of generating electricity, have both held an iconic status in the history of science as well as in the history of science teaching. These experiments featured in chemistry and physics textbooks, as well as in classroom teaching, throughout the nineteenth and twentieth…

There is on-going international interest in the relationships between assessment instruments, students' understanding of science concepts and context-based curriculum approaches. This study extends earlier research showing that students can develop connections between contexts and concepts--called "fluid transitions"--when studying…

A wide variety of out-of-school time (OST) programs across the U.S. offer science education opportunities that cover many scientific disciplines and use diverse pedagogical practices (National Research Council [NRC], 2009). However, to improve youth's scientific literacy, OST educators need to "have the disposition and repertoire of practices…

This review explores Ben-Zvi Assaraf, Eshach, Orion, and Alamour's paper titled "Cultural Differences and Students' Spontaneous Models of the Water Cycle: A Case Study of Jewish and Bedouin Children in Israel" by examining how the authors use the concept of spontaneous mental models to explain cultural knowledge source of Bedouin…

There has been much interest in magnetite (Fe[subscript 3]O[subscript 4]) due to its utility in adsorbing high concentrations of arsenic in contaminated water. The magnetic properties of the material allow for simple dispersion and removal from an aqueous system. An inquiry-based laboratory has been developed that illustrates these unique…

Teaching about the nature of science is seen as a priority within science education, and has also been highlighted as a suitable context for challenging the most able ("gifted") learners at secondary school level. This article discusses a practical session designed to introduce the idea of physical (natural) laws. The session asks…

This document describes some experiences in a science/technology/society (STS) program for an eighth grade science course at a small rural school in Iowa. The background information about the school and the general goal of the STS program are outlined. The curriculum structure of the program related to water as a reusable resource is presented.…

This article presents a model for the development of an environmentally oriented unit designed to be implemented as an integral part of the science core curriculum. The program's main goal is encouraging students at the junior high-school level to develop systems-thinking and environmental insight as a basis for environmental literacy. A…

Discusses the need for hands-on training for technician-level chemists. Describes a technician training program at Southeast Community College that emphasizes wastewater plant operations and laboratories. Outlines the course sequence for the six-quarter environmental laboratory technician curriculum. (TW)

This document was designed to help teachers provide ninth grade students in New York City with opportunities to learn about scientific processes as well as basic reasoning skills which underlie problem-solving processes in scientific and nonscientific disciplines. The first section of the guide, "The Environment," contains lessons which…
