"Such Cases of Outrageous Unspeakable Abuse...": A Puerto Rican Migrant Protests Labor Conditions Du
In 1917 the United States declared the inhabitants of Puerto Rico, a U.S. possession since 1898, to be citizens of the United States--a "gift" that many Puerto Ricans resented. Seeing an untapped source of inexpensive labor, the U.S. Labor Department worked with industry to facilitate the migration of Puerto Rican workers to America. During the First World War the War Department agreed to transport Puerto Rican workers to labor camps in the United States where they would be housed and fed while
"Nobody Would Eat Kraut": Lola Gamble Clyde on Anti-German Sentiment in Idaho During World War I
When the United States went to war against Germany in 1917, German Americans faced vicious and unfair attacks on their loyalty. Many anti-German incidents were not recorded, but they lived on powerfully in people's memories. In this 1976 interview, Lola Gamble Clyde, the daughter of an Irish-born Presbyterian minister and a teenager during World War I, described the "hysteria" that faced German Americans in rural Latah County, Idaho.
Volcanoes of other worlds
Volcanoes of Other Worlds explores and compares volcanism on other planets. What do we know about plate tectonics on other planets? Planetary bodies highlighted include the Earth's Moon, Mars, Venus and Jupiter's moon Io. Users can also link to Volcano World, an excellent web-source of volcano information.
Cascades Volcano Observatory
This website is the homepage for the United States Geological Survey Cascades Volcano Observatory (CVO). The website covers a variety of information including CVO information, volcano descriptions, menus of interest and miscellaneous information. The site also contains numerous special features ranging from educational outreach to news and current events.
Runaway Greenhouse Effect Exercise
This activity, Runaway Greenhouse Effect Exercise, discusses "Why is Venus so much hotter than the Earth?" This is a collaborative problem-solving exercise about the greenhouse effect on Venus. Students role-play biologists, coal geologists, space warfare experts, astronomers, pollution-control scientists, and hydrophysicists. Each student gets a copy of the appropriate briefing sheet (there are 6) containing some information important to solving the problem, much of it quantitative. On this Sta
Human Impacts on Sharks: Developing an Essay Through Peer-Review on a Discussion Board
Through computer technology (WebCT, Blackboard), students develop a paper topic (in this case, the human impacts on sharks) that is peer reviewed by additional students answering guided questions. This Starting Point page details the learning goals, context of use, teaching materials, and assessment method for this activity. Also included are useful references and resources and topics discussed.
Developing a Local Stratigraphy
In this lab activity students describe rock types in a variety of exposures to construct a regional stratigraphy. Learning goals, teaching notes and materials, equipment lists, and assessment recommendations are all provided on this website. Additionally, there are links to useful references and resources, including related field labs.
Reducing Volcanic Hazards to People and Property - An Assignment with Electronic Peer Review
Through an electronic peer review assignment, students write a general summary of major hazards to humans in the vicinity of volcanoes. Then, students are provided a list of volcanoes and must choose one to determine what actions they would take to minimize the risks to a population. This activity is detailed on this Starting Point site, which includes its learning goals, context for use, teaching notes and materials, recommended assessment method, resources, and references.
Biodiversity stuff to do: Endangered!
This Ology game site contains rules and a board for a board game dealing with extinction, particularly the modern biodiversity crisis. The players need to read endangered species facts from the board to answer questions on the spaces that they land in so that they can progress. Users can follow links to what to do and materials needed for the game.
Wonderful Life: Genes and Evolution
This is the homepage for a course focusing on evolution, the nature of science, and how to write well. The course focuses on Burgess Shale and starts with "Wonderful Life" (Gould, 1989), to study arthropods, evolution, and geologic time from this point, but also analyze why Gould is such an effective writer. The course web site contains the syllabus, descriptions of assignments, links to helpful and interesting resources (including annotated lists of relevant books and scientific controversies),
In this inquiry activity, students view NASA images of galaxies and develop a galaxy classification scheme. Students then compare and contrast their classification scheme with that developed by Edwin Hubble.
Designer Genes for a Designer World
In this series of guided inquiry activities, students explore how organisms adapt to their environments through changes in their genetic codes. The learner will: create make-believe creatures and environments that have specific characteristics; rate the success of each creature in a randomly assigned environment by examining which of the creature's characteristics help, hinder, or have no effect on the creature's success in each environment; write the genetic code for their creatures from a lis
