This problem-based case study guides students through a systematic exploration of the scientific issues surrounding the application and development of hydrogen fuel technology. A PowerPoint presentation introduces a New York Times article about the impact of our abundant natural gas resources on the cost of hydrogen fuel production. The article includes an Energy Department estimate that places the gasoline-cost equivalent of hydrogen fuel production, compression, and distribution at less than $4 per gallon, making it a viable option for the transportation sector. Students are then given primary literature articles and a worksheet to help them examine (1) the benefits and drawbacks of using hydrogen as a fuel in automobiles and trucks, (2) the current technological/engineering limitations of using hydrogen fuel, and (3) whether the pursuit of developing large-scale use of hydrogen-powered cars is the right direction for the country. Originally written for a second semester/second quarter general chemistry course, the case study is designed to illustrate the direct application of chemical thermodynamics and gas laws to the production and distribution of renewable fuels.
Set against the restoration of war-torn Gorongosa National Park in Mozambique, The Guide tells the story of a young man from the local community who discovers a passion for science after meeting world-renowned biologist E.O. Wilson.
Discussion guides and more as well.
Scientists have combined cookies, citizen science and robust research methods to track the diversity of ant species across the United States, and are now collaborating with international partners to get a global perspective on how ants are moving and surviving in the modern world. The School of Ants project was developed to help researchers get a handle on the diversity of ant species across the United States.
Pretty cool citizen science.
Anyone can participate! Learn how to create your own sampling kit, sample your backyard or schoolyard, and get our collection back to us so that we can ID the ants and add your species list to the big School of Ants map. Together we'll map ant diversity and species ranges across North America!
