This site provides visual resources and supporting material about the study of sequence stratigraphy. Resources accessible from this site include informational text, images, animations and short videos which can be integrated into lectures, labs or other activities.
This site is a set of lecture notes from a petrology class by Dr. Susan DeBari at Western Washington University. The lectures explain the process of mineral crystallization and phase relationships as a function of temperature and pressure. Topics covered include the phase rule, one-component systems (unary), two-component systems (binary), and three-component systems (ternary), as well as equilibrium crystallization, equilibrium melting, fractional crystallization, and fractional melting. Diagra
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.
Underneath the Mountains
These lecture notes discuss the role of buoyancy, flexure, and erosion in the earth's topography and the lifetime of mountain ranges. It recalls Pascal's law that pressure of a material overlying a fluid is equal everywhere at a given depth and Archimedes' principle that a body in a fluid is buoyed up with a force equal to the weight (mass x volume) of the displaced fluid. Continents are buoyant crust floating on denser mantle, so a 4 km high mountain range must have a 20 km deep root. According
This collection provides a wide array of visual resources and supporting material about the December 26, 2004 Indian Ocean Tsunami. Visualizations include simple animations, satellite photographs, Quicktime animations and tsunami models. The collection also contains visualizations related to other historical tsunamis and additional resources (beyond visualizations) about tsunamis. Resources can be incorporated into lectures, labs, or other 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
Teaching Structural Geology in the 21st Century
This site from the "On the Cutting Edge" workshop series offers a variety of resources for faculty members who teach undergraduate structural geology. There are collections of classroom activities, internet and computer resources, useful articles and maps, presentations from the summer 2004 workshop on teaching structural geology, working groups and a discussion forum, and lots of creative ideas for teaching structural geology. Students will also find the site useful for supplementing class lect
Teaching Structural Geology in the 21st Century
This site from the "On the Cutting Edge" workshop series contains a collection of activities that can be used in undergraduate structural geology courses. The collection includes lab exercises, classroom activities, problem sets and more.
Teaching About the Ocean System Using New Research Techniques: Data, Models and Visualization
This web collection from the "On the Cutting Edge" workshop series will help undergraduate faculty and students use a new approach to teaching and learning oceanography. The site features the use of models, datasets and visualizations in teaching. The site features a collection of data-rich resources, example teaching activities and visualizations that illustrate oceanography topics. Materials from the 2005 workshop on teaching oceanography are also included.
Solar System Animations
This site features Flash animations that illustrate phases of the moon, distances between planets, total, partial, and annular eclipses, and solar system formation that includes an example of the impact that created the moon. These resources are suitable for use in lectures, labs, or other teaching activities.
Maritime History of Massachusetts
This is is a travel itinerary highlighting 89 historic places that tell the story of Massachusetts' relationship with the sea. Read essays about lighthouses and lifesaving stations, ships and shipbuilding, the U.S. Navy, and maritime commerce.
The Lewis and Clark Expedition: Documenting the Uncharted Northwest
recounts the expedition's crossing of the Lemhi Pass and Lolo Trail, and the time spent at Fort Clatsop near the Pacific Ocean. Although the Corps of Discovery did not realize its dream of finding a water route to the Pacific Ocean, the expedition overcame many obstacles and dangers to open the Northwest to the influence of the U.S., established relations with American Indian tribes, and gathered useful scientific documentation.
Saint-Gaudens National Historic Site: Home of a Gilded Age Icon
Looks at this place in western New Hampshire where the sculptor Augustus Saint-Gaudens established a summer home and studio (1885), conceived a host of projects, became the leader of an art colony, battled cancer, and was buried. It is a window on one aspect of the Gilded Age: the role of the artist.
Two American Entrepreneurs: Madam C.J. Walker and J.C. Penney
This site features the life stories of two business people who lived the American Dream and who helped make that dream a reality for others in their communities. It tells how Walker, an African American woman, and Penney, a former tuberculosis patient, built from scratch their multi-million and billion dollar businesses.
Lexington, Kentucky: The Athens of the West
highlights 29 places that illustrate the transformation of the city from a small frontier post during the Revolutionary War into a center of economic, intellectual, and political activity. Photos, maps, and essays are included.
The Battle of Prairie Grove: Civilian Recollections of the Civil War
helps students place the Battle of Prairie Grove in the context of Arkansas' role in the Civil War. Photos and readings from eye witness accounts of the battle depict the harsh realities of Civil War and its effects on both soldiers and civilians.
The News About the News
This lesson will invite students to explore how news shows are constructed and to assess the way a newscast prioritizes different categories of news.
Representing History: Cambodia - Through the Shadows
This unit introduces students to the modern history of Cambodia in the context of the Cold War. It examines the relationship between Cambodia and Vietnam and the way both countries became drawn into the power struggle between the US and Western capitalism and the Sino Soviet communist axis in the east. Through viewing and discussion of the video and investigating the web resources, students can begin to understand the conventions of documentary in offering access to a version of the truth.
