Course-integrated Undergraduate Research Experiences (CUREs) involve large numbers of students in real research. We describe a late-year microbiology CURE in which students use yeast to address a research question around beer brewing or synthesizing biofuel; the interdisciplinary student-designed project incorporates genetics, bioinformatics,…

We designed a hands-on laboratory exercise to demonstrate why injecting an aqueous polymer solution into an oil reservoir (commonly known as "polymer flooding") enhances oil production. Students are split into three groups of two to three. Each group is assigned to a packed Hele-Shaw cell pre-saturated with oil, our laboratory model of…

Rocket propulsion is often introduced as an example of Newton's third law. The rocket exerts a force on the exhaust gas being ejected; the gas exerts an equal and opposite force--the thrust--on the rocket. Equivalently, in the absence of a net external force, the total momentum of the system, rocket plus ejected gas, remains constant. The law of…

Roadways are literally soaked with petrochemical byproducts, oils, gasoline, and other volatile substances that eventually run off into sewers and end up in rivers, waterways, and other undesirable places. Can the roads be cleaned of these wastes, with their proper disposal? Can vehicles, robots, or other devices be designed that could be driven…

As the United States strives to achieve energy independence, students need to be literate about energy and environmental issues. In this article, the authors present a lesson about the nation's electricity resources that is part 1 of a free, comprehensive unit on coal and energy that is available online (http://tinyurl.com/coalenergyunit). The…

The Deepwater Horizon explosion on April 20, 2010, and the subsequent release of oil into the Gulf of Mexico created an ecological disaster of immense proportions. The estimates of the amounts of oil, whether for the amount released per day or the total amount of oil disgorged from the well, call on numbers so large they defy the capacity of most…

The United States is currently experiencing its worst man-made environmental disaster, the BP Deepwater Horizon oil leak. The Gulf of Mexico oil spill is severe in its impact, but it is only one of several global oil spill disasters in history. Students can utilize the technology of Google Earth to explore the spatial and temporal distribution of…

To engage students in a real-world issue (Bransford, Brown, and Cocking 2000) that affects their communities, the author designed an entire unit to investigate air pollution in their home state, Connecticut. The unit's goal is to understand how the use of resources, such as fossil fuels, might affect their quality of life. Through this unit,…

A significant issue associated with ethanol-gasoline blends is the phase separation that occurs with the addition of small volumes of water, producing an ethanol-deficient gasoline layer and an ethanol-rich aqueous layer. The gasoline layer may have a lower-than-desired octane rating due to the decrease in ethanol content, resulting in engine…

A multi-tool approach incorporating traditional lectures, multimedia learning objects, and a laboratory activity were introduced as the concepts surrounding hydrogen fuel-cell technology in college chemistry courses. The new tools are adaptable, facilitating use in different educational environments and address variety of learning styles to…

A survey of adults that shows considerable misunderstanding of two major ideas--that there is no energy in fuels and burning involves two stages--is discussed. Proposed are fundamental changes in the way ideas about burning are introduced to children. (KR)

When the fossil fuels unit was first designed for Science 101 (the currently approved provincial guide for grade 10 science in Manitoba), Canadian support materials were very limited. Since students are asked to interpret data concerning energy consumption and sources for certain fossil fuels, the need for appropriate Canadian data became obvious.…

Describes exercises to examine the global carbon cycle. Students are asked to predict consequences of increased carbon dioxide emissions into the atmosphere and to suggest ways to mitigate problems associated with these higher levels of atmospheric carbon dioxide. A comparison modeling exercise examines some of the variables related to the success…

The Northwest Power Plan, developed by the Northwest Power Planning Council to deal with the increasing demands for energy by the Pacific Northwest, is discussed. An idea of how sufficient energy could be produced as well as preserve the qualities of life that make the Pacific Northwest special is presented. (KR)

The Zimbabwe Secondary School Science Project (ZIM-SCI) developed student study guides, corresponding teaching guides, and science kits for a low-cost science course which could be taught during the first 2 years of secondary school without the aid of qualified teachers and conventional laboratories. This teaching guide, designed to be read in…
