This paper focuses on pupils' perceptions of water issues. The instructional situations take place in a Finnish primary school and aim at introducing the Science-Technology-Society (STS) study approach. The primary aim of this study is, in the context of STS instruction, to describe issues that pupils associate with water. This paper involves…

The use of silver in commercial products has proliferated in recent years owing to its antibacterial properties. Food containers impregnated with micro-sized silver promise long food life, but there is some concern because silver can leach out of the plastic and into the stored food. This laboratory experiment gives students the opportunity to…

Sears-Dundes, Christopher; Huon, Yoeup; Hotz, Richard P.; Pinhas, Allan R. – Journal of Chemical Education, 2011
An experiment has been developed in which the hydrogen-atom abstraction and the coupling of propionitrile, using Fenton's reagent, are investigated. Students learn about the regiochemistry of radical formation, the stereochemistry of product formation, and the interpretation of GC-MS data, in a safe reaction that can be easily completed in one…

Chunrasaksakun, Chunwadee – Educational Research and Reviews, 2015
The aim of this study is to investigate the effects of training teachers to enhance their students' achievements in water resource and disaster course and to compare the effects of using the curriculum framework between training teachers or using curriculum framework in the secondary schools in Khon Kaen Province of Thailand. It was found that the…

Losing the Lake: Simulations to Promote Gains in Student Knowledge and Interest about Climate Change
Nussbaum, E. Michael; Owens, Marissa C.; Sinatra, Gale M.; Rehmat, Abeera P.; Cordova, Jacqueline R.; Ahmad, Sajjad; Harris, Fred C., Jr.; Dascalu, Sergiu M. – International Journal of Environmental and Science Education, 2015
Climate change literacy plays a key role in promoting sound political decisions and promoting sustainable consumption patterns. Based on evidence suggesting that student understanding and interest in climate change is best accomplished through studying local effects, we developed a simulation/game exploring the impact of climate change on the…

Enninful, Ebenezer Kofi; Boakye-Amponsah, Abraham; Osei-Poku, Patrick – Journal of Education and Practice, 2015
The printing industry is supposed to be a major contributor to Ghana's development through employment creation and the enhancement of information to the general public. The main purpose of the study was to assess employee motivation on the printing industry within Kumasi Metropolis. The study employed both the quantitative and qualitative surveys…

Newman, Jane L.; Dantzler, John; Coleman, April N. – Theory Into Practice, 2015
The purpose of Science in Action (SIA) was to examine the relationship between implementing quality science, technology, engineering, and math (STEM) service-learning (SL) projects and the effect on students' academic engagement in middle school science, civic responsibility, and resilience to at-risk behaviors. The innovative project funded by…

Howard, A.; Heitman, J. L.; Bowman, D. – Journal of Natural Resources and Life Sciences Education, 2010
It is difficult to demonstrate the soil water retention relationship and related concepts because the specialized equipment required for performing these measurements is unavailable in most classrooms. This article outlines a low-cost, easily visualized method by which these concepts can be demonstrated in most any classroom. Columns (62.5 cm…

Sommer, Wilfried; Meier-Boke, Ralf; Meinzer, Nicholas – Physics Teacher, 2010
The hydromonochord is a horizontal vibrating string that just makes contact with the surface of a water bath. The motion of the string sets up a pattern of swirls on the surface of the water, thus complementing the usual pattern of nodes and antinodes. The device is based on the traditional monochord. A water basin (Fig. 1) has two slits in the…

This article describes the projects on solar hydrogen powered vehicles using water as fuel conducted by teams at Brooklyn Technical High School. Their investigations into the pure and applied chemical thermodynamics of hydrogen fuel cells and bio-inspired devices have been consolidated in a new and emerging sub-discipline that they define as solar…

Sinick, Scott J.; Lynch, John J. – Physics Teacher, 2010
In this work, an inexpensive 10-gallon glass aquarium was used to study wave motion in water. The waves travel at speeds comparable to a person walking ([approximately]1 m/s). The scale of the motion allows for distances to be measured with a meterstick and for times to be measured with a stopwatch. For a wide range of water depths, standing waves…

Schouten, Peter; Putland, Sam; Lemckert, Charles J.; Parisi, Alfio V.; Downs, Nathan – Physics Education, 2012
Across the world, freshwater is valued as the most critically important natural resource, as it is required to sustain the cycle of life. Evaporation is one of the primary environmental processes that can reduce the amount of quality water available for use in industrial, agricultural and household applications. The effect of evaporation becomes…

Keller, John W.; Fabbri, Cindy E. – Journal of Chemical Education, 2012
Analysis of halogenated volatile organic compounds (HVOCs) by GC-MS demonstrates the use of instrumentation in the environmental analysis of pollutant molecules and enhances student understanding of stable isotopes in nature. In this experiment, students separated and identified several HVOCs that have been implicated as industrial groundwater…

Mugnai, Riccardo; Barbosa, Julio Vianna; Baptista, Darcilio Fernandes – Journal of Biological Education, 2012
Teaching collections are of great importance for science instruction at any level. There are several problems linked to the handling and curatorial management of this kind of collection. Among these is the relatively short life-span of specimens, due to the damage from continuous handling by students. Often the specimens used to replenish the…
