Wonderful Life: Genes and Evolution
This is the homepage for a course focusing on evolution, the nature of science, and how to write well. The course focuses on Burgess Shale and starts with "Wonderful Life" (Gould, 1989), to study arthropods, evolution, and geologic time from this point, but also analyze why Gould is such an effective writer. The course web site contains the syllabus, descriptions of assignments, links to helpful and interesting resources (including annotated lists of relevant books and scientific controversies),
Quicksand Questions: Short In-class Activity
This Starting Point classroom activity prompts students with questions during a lecture on quicksand. Their answers can be collected with classroom response systems or through a think-pair-share activity. This activity allows an instructor to review the answers with the class and immediately address any points of misunderstanding or content areas that need clarification. The details of this exercise are found on this website, which provides learning goals and context, teaching materials such as
The Berlin Blockade
Clark Clifford was special counsel to President Harry S. Truman from 1946 to 1950. In this video segment, he recounts the 1948 Berlin blockade-the first major East-West confrontation in which Western policymakers were required to grapple with choices that risked war with the Soviet Union, a power seen as capable of overrunning Western Europe. Clifford recalls assessing the risk of an unexpected escalation of tension if moves made by the West were perceived as provocations. He heralds the decisio
Part of the supporting resources for the School of Earth Sciences dynamic earth module, the -Why Topography?- site discusses two models introduced in the 19th century that are still used to explain topographic variations. These models are the Pratt and Airy models of isostasy. In the Pratt model, high topography (relative to surroundings) is due to lower density whereas in the Airy model, high topography is due to thick crust.
This site features Flash animations that illustrate the development of soil horizons and their characteristics. Animations depict the processes of eluviation and illuviation, soil thickness and biomantle development, and a typical progression of soil profile development from bedrock to mature soil. These visual resources may be suitable for integration into lectures, labs and other teaching activities.
Postglacial Flooding of the Bering Land Bridge
This geospatial animation shows sea level rising across the land bridge between Siberia and Alaska. During the last Glacial Maximum (~21,000 years ago), the Bering Land Bridge was a vast tundra plain connecting Asia and North America. At that time, the global sea level was 120 meters lower than it is today. Melting ice sheets and glaciers caused the sea level to rise and flood the land bridge. A QuickTime file of this animation can be viewed or downloaded for analysis, education and outreach. Th
