Of all the animals in the oceans, the hammerhead shark may be one of the strangest looking. The exact purpose of the wide, flat head is a mystery, but several theories abound. In this video, we travel to the shark-infested waters of the Galapagos in Ecuador and to a research station in Hawaii to learn about the unusual habits of these sinister-looking sharks. Jonathan swims in schools of hundreds of hammerheads, and yet the sharks ignore him. What are the sharks up to? Please see the accompanying study guide for educational objectives and discussion points.

Learning module on NAFTA, its effects and future possibilities for North American integration.

The survey was designed to obtain national benchmarks on a wide range of health issues, and to enable changes in health to be monitored over time. Information was collected about: the health status of the population; health-related aspects of lifestyle and other health risk factors; and the use of health services and other actions people had recently taken for their health."

In this video segment adapted from Haskell Indian Nations University, student filmmakers explain why it is important to them to make a video about climate change.

This activity uses a cultural story to excite kinesthetic homework, nature journaling and daily adventure in a child's own back yard or kitchen flower pot.

In this video segment adapted from Navajo Technical College, meet two members of the Navajo Nation, one Elder and one scientist, as they share their observations about how precipitation has changed since they were children.

This searchable timeline describes Navajo history from 1200 BC through the year 2002. Throughout the timeline, historical events of the Navajo are described and paired with world history. Useful links to topics concerning the Navajo can be found in the later periods within the timeline. Users can search the timeline using a pull-down menu of time periods.

This bibliography, compiled by the Southwest Research and Information Center, contains resources related to Navajo uranium issues and communities affected by uranium mining impacts since the mid-1970s. Entries were selected for their relevancy to Navajo community concerns, Navajo Nation policies, and health and environmental effects of uranium development on Navajo lands. Topics for resources include articles, books, policy statements, reports, presentations, testimony, and published medical, scientific and sociological literature.

Conventional legislative, administrative, and judicial means of resolving resource allocation and policy disputes in the public sector often produce less than satisfactory results. This is true in democracies around the world. Planners, policy-makers, developers, and advocates of the poor who are concerned about the fairness, efficiency, stability, and wisdom of public sector decision-making are searching for better ways of resolving public policy disagreements. Recent advances in the theory and practice of multi-party negotiation and dispute resolution are, therefore, of great interest. 
This seminar is designed for graduate students with no prior background or experience in the fields of  negotiation or dispute resolution. Lectures, scenarios, case studies, video analysis, and role-play simulations are used to introduce students to the “art” and “science” of negotiation and consensus building. The class also provides an intensive opportunity for each student to build their personal theory of practice and to strengthen their negotiating capabilities.

Bar chart of countries ranked by their net migration flow as of 2005. While the highest net in-flow is generally into large rich countries (USA, Spain, Germany etc.) Afghanistan had the second highest net inflow thanks to returning refugees.

Networks are ubiquitous in our modern society. The World Wide Web that links us to the rest of the world is the most visible example. But it is only one of many networks in which we are situated. Our social life is organized around networks of friends and colleagues. These networks determine our information, influence our opinions, and shape our political attitudes. They also link us, often through weak but important ties, to everybody else in the United States and in the world. 
This course will introduce the tools for the study of networks. It will show how certain common principles permeate the functioning of these diverse networks and how the same issues related to robustness, fragility, and interlinkages arise in many different types of networks.

The Adirondack Mountains tour is part of the New York Landscape Regions Collection of Google Earth Tours, created by a group of New York State science educators. This tour provides an introduction to the geology of the Great Range and the High Peaks as viewed from Algonquin Peak. It also addresses the issue of acid rain, which is a persistent environmental concern in the Adirondacks.

The Allegheny Plateau tours are part of the New York Landscape Regions Collection of Google Earth Tours, created by a group of New York State science educators. These tours showcase examples of Allegheny geology, including the geomorphology of glacial features near Tully, New York, southern Cayuga Lake, the geology and geomorphology of Letchworth State Park and its waterfalls, as well as waterfalls and creeks in the Ithaca Gorges. Schoharie Creek can be toured from its mouth to its source, the St. Lawrence Chesapeake and Valley Heads Moraine can be investigated to examine drainage patterns, and another tour investigates the unique geology and ecology of the Rome Sand Plains. Environmental tours also address the 2006 flooding in the Allegheny Plateau near Port Jarvis and Livingston Manor and provide an overview of the water supply system of the City of New York.

The Atlantic Coastal Plain tour is part of the New York Landscape Regions Collection of Google Earth Tours, created by a group of New York State science educators. This tour introduces students to glacial erratics on Long Island, the Ronkonkoma terminal moraine, and the Rock Hill erratic. Coastal erosion and deposition can be studied by viewing dunes, beaches, and wave cut banks.

The Erie Ontario Lowlands tour is part of the New York Landscape Regions Collection of Google Earth tours. This tour includes glacial history, features, and views of Niagara Falls, the Niagara Escarpment, current and former spillways, and the locks at Lockport, New York. Students can also learn about the geology and glacial history of Canandaigua Lake, one of New York's Finger Lakes, which discharges into the Lowlands. There is also a lab activity in which students analyze maps, images, and information to perform an environmental assessment of the Cascade Mill development.

The Hudson Highlands tour is part of the New York Landscape Regions Collection of Google Earth Tours, created by a group of New York State science educators. This tour introduces Hudson Highlands geology, including glaciology at Bear Mountain, views of the Highlands, and the Ramapo Fault to the south. It also offers other information about the area, including some animals, New York City's water supply, and the Great Swamp.

The Hudson Mohawk Lowlands tour is part of the New York Landscape Regions Collection of Google Earth tours, created by a group of New York State science educators. This tour introduces students to limestone quarrying along the western shore of the Hudson River south of Catskill, New York. They can follow the courses of the Mohawk River and Erie Canal eastward to the Cohoes Falls and the confluence of the Mohawk with the Hudson River. It also provides a look at issues involved with the cleanup of PCB-laden sediments in the Hudson River.
