Weir Farm: Home of an American Impressionist
This site examines the farm acquired by painter Alden Weir (1852-1919), where he summered for nearly 40 years (northeast of New City). At a time railroads were expanding, populations were increasing, and America's agrarian system was being replaced by industry, Weir was an artist who found inspiration in the quiet everyday settings of New England, and, in many ways, defined our vision of the American landscape.
The Influences of Art on Yellowstone
This site features paintings, photos, and drawings, many of which contributed to the creation of the nation's first national park. The waterfalls, geysers, rock formations, and vistas in these works helped spread an appreciation of the wonders of Yellowstone. When President Grant signed into law the bill establishing Yellowstone as our first national park in 1872, he set in motion the tradition of preserving other tracts of great beauty for future generations.
American Visionaries: Thomas Moran
features paintings and sketches of the noted American landscape painter. Moran's pencil and watercolor field sketches and paintings captured the grandeur and documented the extraordinary terrain and natural features of the Yellowstone region. His artwork was presented to members of Congress by park proponents and helped inspire Congress to establish the National Park System in 1916.

Windows Into Wonderland - Yellowstone Electronic Field Trips
The geysers and hot springs of Yellowstone are surface manifestations of larger geological processes—the study of which has attracted scientists for more than 100 years. This 55 minute interactive program discusses how early studies were conducted in the park and illustrates that scientific research is an ongoing process. Students will learn how research methods change with technological advances and examine current investigations into the geologic forces of the vast living laboratory of Yello
You Decide: Should U. S. airport security use profiles that include ethnic profiling characteristics
This educational guide focuses on ethnic profiling and related issues. Students are invited to examine the arguments on both sides of the debate, developing critical thinking skills as they work through the activities.
