Document: http://sciencecases.lib.buffalo.edu/cs/collection/detail.asp?case_id=490&id=490 Abstract: The release of toxins into the environment and the federal government’s tracking of that using the Toxic Release Inventory (TRI) compiled by the U.S. Environmental Protection Agency (EPA) are the focus of this case study, which uses GIS to explore the potential impacts of the release of such substances. The case was developed for an introductory environmental...

Document: http://sciencecases.lib.buffalo.edu/cs/collection/detail.asp?case_id=421&id=421 Abstract: In this dilemma case study, the executives of a popular restaurant chain must decide whether to use irradiated meat, in this case, beef, to protect its customers from the bacteria, E. coli. Students learn about food irradiation and discuss issues related to food safety and the public’s acceptance of new food technologies. As developed, the case could be...

Document: http://sciencecases.lib.buffalo.edu/cs/collection/detail.asp?case_id=419&id=419 Abstract: In this case study, students hear arguments on both sides of a debate over wildlife management and must integrate ethical and scientific perspectives to formulate their own opinions. The case as written is most appropriate for an environmental ethics or policy course, but could also be used in an introductory or interdisciplinary environmental studies course.

Document: http://sciencecases.lib.buffalo.edu/cs/collection/detail.asp?case_id=197&id=197 Abstract: In this case study, students speculate on what may have caused a major fish kill in an estuary in North Carolina. In the process, they explore how land runoff and excess nutrients affect aquatic communities, and learn about the complex life cycle of the dinoflagellate Pfiesteria. The case is appropriate for an introductory environmental science course, a general...

Document: http://sciencecases.lib.buffalo.edu/cs/collection/detail.asp?case_id=599&id=599 Abstract:This case explores two-species interactions, especially mutualism, and presents students with a problem, namely, the inconsistent treatment of the concept of mutualism and symbiosis in many textbooks. It begins with a question that students will probably not feel qualified to answer: Is the equation of mutualism and symbiosis in a textbook correct? It then guides students through...

Document: http://sciencecases.lib.buffalo.edu/cs/collection/detail.asp?case_id=272&id=272 Abstract: This case is an exploration of the process of natural selection using white clover (Trifolium repens) as an example. In general, two forms of white clover can be found around the world in various habitats. One type is able to produce cyanide in its leaves, while the other is not. This variation within the clover species,...

Document: Valence Graphic Organizer Abstract: Number of valence electrons for the atoms of this group

Document: Draw an Atom Learning Task (1)   Abstract This task was begun in the Unit, Finding Order; in this unit, this task is repeated after instruction on the wave-mechanics model of the atom.  

Document:ElementRoundtable   Abstract: Element Silent Roundtable Task-This task is an example of an activating, team-building strategy. Each student will write with a different color marker. When instructed to start, one member of the group will write the name of an element on the board, then pass it to the right. Each member of the group will add one element...

Document: Chemistry Unit 2 – Finding Patterns Abstract: This unit, Finding Patterns, takes an inquiry approach to understanding the patterns of properties that exist among the elements. These patterns in properties are then linked to the wave-mechanics concept of atomic structure and the quantum atom. Beginning with isotopes and average atomic mass, as a way of understanding the importance of the...
