This interactive resource adapted from The Virtual Cave by Dave Bunnell, presents images of various features found in solution caves and includes detailed information on how these features are formed and where they occur.
Early Image: A collection of illustrations from popular sources.
Early Image is a collection of extinct-animal paintings and sketches produced before 1923 (and therefore in the public domain). Some of the works are of Victorian age and may lend atmosphere to a class emphasizing the history of geology. The works are divided into two categories; prehistoric life before KT and prehistoric life after KT.
"They Are Mostly All Foreigners on Strike": Joseph Fish 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, Homestead, Pennsylvania, steelworker Joseph Fish described conditions in the steel mills as good and maintained that only "one or two" Americans have joined the strike.
Bruce Kent, ordained a Catholic minister in 1958, became general secretary of the Campaign for Nuclear Disarmament (CND) in 1980 and chairman in 1987, the year he resigned from the ministry. In this video segment, he challenges the damaging spin that secretary for defense Lord Michael Heseltine used to undermine CND rather than engage in public debate about nuclear policy. Kent also refutes accusations that CND was in support of 'one-sided,' full unilateral disarmament. Instead, he argues for 's
'City Archives' was written and directed by Richard Foreman, founder and director of the Ontological Hysteric Theater. He serves as the narrator for this work, discussing the power of 'the foreign' and images, talking directly into a microphone in a purposely stilted manner and addressing questions to the viewer. A sort of classroom overpopulated by adults sets the stage for the work. Phrases are written and erased on a blackboard, and women gaze out a window, physically supporting planks of woo
Using Field Labs
Starting Point's introduction to the use of field labs in entry level geoscience classes. The page is a portal to lab examples, a discussion of the benefits of a lab curriculum, and an exploration of the logistical and pedagogical considerations of using field labs. Includes a bibliography and relevant articles from the Journal of Geoscience Education.
Chinese Chestnut Tree Identification
The Chinese Chestnut is commonly mistaken for the American Chestnut. Here are some pointers on the differences between the two. The American Chestnut Society is attempting to re-establish the latter in the North American forest, and biotype diversity requires many American Chestnut crosses with resistant forms.
The Amazing Microbe Hunters
This activity from our family magazine series provides a fun way for kids to learn about how early microbe discoveries led to later ones. The online activity begins with a page of directions for how to play this "hidden picture" challenge. Kids meet the people behind six key discoveries: Anthony van Leeuwenhoek, Edward Jenner, Louis Pasteur, Alexander Fleming, Jonas Salk, Luc Montagnier, and Robert Gallo. To uncover each portion of the hidden picture (an animated microscope) and move to the next

'Color Schemes' features twelve performers and writers of color who collaborate to recount incidents of racism, particularly racism in the entertainment industry. The work uses the metaphor of washing a load of colored clothing and is divided up into four sections based on laundry cycles. Cycle One, 'Soak,' opens with an archival piece of animation about the price of labor, with a particularly offensive rendition of a Chinese man who is referred to repeatedly as a 'coolie.' In a staged vignette,

A young man finds himself in a love triangle involving his brother and his brother's girlfriend, so he turns to Jesus, by calling him on a pay phone. An experimental narrative, 'Radio Inside' explores the struggle between faith and flesh, where black-and-white imagery is contrasted with the protagonist's own thoughts presented in the form of music from various radio channels, from gospel to rock and roll. Contemporary in its style and preoccupations, 'Radio Inside' expresses a particular kind of
Meaning of the Interval
'Meaning of the Interval' is a reflection on openings or intervals that the Japanese call 'ma,' and how they apply to any number of activities in Japan. 'Ma' can be architectural space, the vast stretches of empty space employed in Japanese scroll paintings, or the time between one utterance and another on the Noh stage. Images from Japanese public life, ceremonies, and performances are juxtaposed and layered. Sometimes a split-screen approach is used. Scenes include a Butoh dance performance,
'Hart Island' tells the story of the uses of Hart Island, which has served as an internment locale for homeless men, drug addicts, and prisoners, and as a defense training ground. The work alternates images of Hart Island and the activity there with visual text describing its history. Close-up views of men unloading boxes and digging holes are seen. As the text gradually makes clear, these men are inmates from Rikers Island prison on a work crew. Their job is to bury the unclaimed dead (includin
