Dating Lava Flows on Mauna Loa Volcano, Hawaii
In this video segment adapted from NOVA, scientists search for carbonized remains of plants preserved in lava flows to find out how long it has taken rain forests on Hawaii to regenerate after a volcanic eruption.
"That Broke Down the Ethnic Barriers": A Steelworker Describes the Decline of Ethnic Hostility in th
Tensions among industrial workers of different ethnic backgrounds often proved a barrier to unionization in the late nineteenth and early twentieth centuries. It was, for example, a key factor in the defeat of the 1919 steel strike. In the 1930s, however, that began to change, particularly under the auspices of the CIO. In this 1974 interview done by historian Peter Gotlieb in 1974, Polish-American steelworker Joe Rudiak recalled how ethnic hostility declined in the "CIO days," particularly amon
"Kill the Indian, and Save the Man": Capt. Richard C. Pratt on the Education of Native Americans
Beginning in 1887, the federal government attempted to "Americanize" Native Americans, largely through the education of Native youth. By 1900 thousands of Native Americans were studying at almost 150 boarding schools around the United States. The U.S. Training and Industrial School founded in 1879 at Carlisle Barracks, Pennsylvania, was the model for most of these schools. Boarding schools like Carlisle provided vocational and manual training and sought to systematically strip away tribal cultur
"Oh God, For One More Breath": Early 20th century Tennessee Coal Miners' Last Words
Coal mining and railroad work were the two most dangerous trades in the United States in the early 20th century. Coal miners frequently died in spectacular explosions and cave-ins that could kill dozens or even hundreds at a time. Although most testimony about coal mining disasters came from survivors and observers, the men who suffocated to death in the Fraterville, Tennessee mines in May 1902 left behind their own grim account. Trapped in the mine after an explosion and with their air rapidly
"We Ought to Have the Right to Belong to the Union": Frank Smith Speaks on the 1919 Steel Strike
In the dramatic 1919 steel strike, 350,000 workers walked off their jobs and crippled the industry. The U.S. Senate Committee on Education and Labor set out to investigate the strike while it was still in progress. In his testimony before the committee, Hungarian-born Frank Smith, a Clairton worker, used his support for the war effort as evidence of his Americanism. "This is the United States," he argued, "and we ought to have the right to belong to the union."
Goodbye Honey Buckets
In this case study activity, students will investigate arctic geology and hydrology as well as tundra ecology and consider options for sewage treatment. Public safety, environmental impact, and issues of construction and engineering will be explored. This Starting Point example page builds on the Lifelines Online case study and includes learning goals, context for use, teaching notes and tips, teaching materials, assessment ideas, references and topics covered.
Coffee Coloured Children
'Coffee Coloured Children' is a powerful exploration of the impact of cultural pressure on self-image. Based on the daily experience of mixed-race children, the narrator recalls the pain and confusion of her own childhood spent in an all-white neighborhood with a white mother and an absent black father. The work opens with a video essay showing adults and children of many ethnicities interacting harmoniously to an upbeat and soulful song with a chorus about 'coffee-colored people.' Through narra
Damnation of Faust: Charming Landscape
'Charming Landscape,' the conclusion to Dara Birnbaum's 'Damnation of Faust' trilogy, shows the debris of a demolished city playground. The self-exploratory narration of two teenage girls is played over images of crowd scenes (often violent) from the civil rights movement, student protests, and the Tianenmen Square demonstrations. The work, which is approximately six and one-half minutes long, is dedicated to Pam Hysinger and Georgeann Ditelli, the teenagers whose words serve as narration. Music
Sun's Impact on Earth's Temperature
In this activity, middle school students view NASA images and movies of Venus, Earth, and Mars to deduce weather patterns and manipulate computer models to test competing hypotheses. By completing this activity, the learner will compare weather patterns observed on Venus, Earth, and Mars; manipulate computer models to investigate the influence of solar distance and atmosphere; evaluate various solar system hypotheses using a computer model.
Space Science Is for Everyone: Creating and Using Accessible Resources in Educational Settings
This brochure is offered as a tool for science, technology, engineering and mathematics educators who are working with students with disabilities. Some activity descriptions are supplemented with case study examples addressing a particular disability.
Hodges Health Career - Care Domains - Model
Hodges’ Health Career (Care Domains) Model provides a conceptual framework upon which users can map problems, issues and solutions across four knowledge domains: Interpersonal; Sociological; Scientific; & Political (Autonomy). The public may also be taught to use the model, enabling engagement, understanding and concordance in planning and outcome evaluation. Brian Hodges' original notes, a resources page and links (800+) are included. Additional material on health informatics and the potenti

Physical weathering includes abrasion, fragmentation, frost wedging, and thermal expansion and contraction. Chemical weathering includes solution, oxidation and hydration, and hydrolysis. The lecture notes are supported by images such as photographs, satellite photos, and diagrams depicting glacial features and frost wedging.
At a Crossroads: The King of Prussia Inn
recounts the history of this inn, built originally as a farmhouse in 1719 at an intersection of two roads northwest of Philadelphia, not far from Valley Forge. The inn provided hospitality to travelers when the colony was just a scattering of farms.
