"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
Bandits or Patriots?: Documents from Charlemagne Pralte
In 1910, an international consortium of banks refinanced Haiti's international debt and took control of the country's treasury. In 1914, the bank refused to issue gold payments to the Haitian government and asked the U.S. military to protect the gold reserves. On December 17, 1914, U.S. marines landed in Haiti and moved the gold to the bank's New York vaults. Eight months later, the marines again landed in Port au Prince, Haiti's capital, this time claiming the need to protect foreign lives and
"The Greatest Tyrant in the State of Pennsylvania": A Late Nineteenth-Century Rail Worker Describes
Although publicists for the Gilded Age corporations celebrated efficiency and the science of management, their employees did not always join the celebration. What looked like careful and disciplined management from one perspective was often viewed as petty tyranny from below. While some workers assailed upper management for this abuse others experienced the tyranny more directly in their day-to-day work lives. In this transcript taken from testimony before the U. S. House of Representatives in t
University of California's Museum of Paleontology: Geologic Timeline
University of California's Museum of Paleontology has created a hyperlinked Geologic Timeline with all sorts of details about each time unit that may be useful later in the course. Each hyperlink contains a variety of information including stratigraphy, ancient life, localities and tectonics associated with that specific time period. Users can also link to an Introduction to Geology page and a description of the Museum's geology wing.
Scientist Uses Tombstones to Track Environmental Changes
This National Geographic News article discusses how a scientist uses tombstones to track environmental changes. Geomorphologist Tom Meierding visited more than 700 cemeteries and measured 15,000 tombstones to see what kind of environmental changes they might reveal.
Cascades Volcano Observatory
This website is the homepage for the United States Geological Survey Cascades Volcano Observatory (CVO).

The site also contains numerous special features ranging from educational outreach to news and current events.
This site describes a contest in which students must correctly characterize the horizons of soils in four different pits within a strict time limit. The site contains photographs of the activity as well as links to the Soil Science Education homepage, links, resources, soil science basics, soil and society, soil and the environment, information on working with soil, soil and agriculture and soil and students.
Phases of the Moon
This site contains a series of visualizations of the sun, moon and Earth System and how they relate to the changing face of the moon. Animations are in the form of Java applets, forms for field observation of the moon, and a collection of exercises and PDF versions of background material. There are practice questions and quizzes that discuss the animations.
Eruption! is a volcanic crisis simulation model that showcases a series of villages that surround an active volcano and is part of the Interactive Models for Geological Education Online (IMGEO) series. The goal of the exercise is to preserve as many people and as much property as possible in spite of the threat from the volcano. Students role-play as villagers, the governor, volcanologists, and the press. The rules of the simulation, plus guides for teaching assistants and students, are availabl

Chronos: a network for Earth system history
CHRONOS (Greek: time) aims to create a dynamic, interactive and time-calibrated framework for Earth history. CHRONOS's main objective is to develop a network of databases and visualization and analytical methodologies that broadly deal with chronostratigraphy - that is, with developing a better tool (the time scale) for understanding fundamental Earth processes through time. The CHRONOS platform will provide a new investigative environment for interdisciplinary Earth history research that includ
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.
The Nancy Creek Challenge
The Nancy Creek Challenge is part of the Starting Point module. The Case study requires students to examine fish kill in Nancy Creek and identify the environmental conditions that favor life in a fresh water ecosystem. Students will work in small groups to assess the situation. The group will be allowed to gather resources from various places in an effort to develop a possible solution for the situation. The page also contains information regarding learning goals, context for use, teaching notes
In this Starting Point case study, students will explore wetland hydrology and biology. They will decide whether or not to restore a wetland or retain dams and drainage systems. Students will also examine the complexity of decisions regarding wetland restoration as well as investigate viewpoints of various stakeholders in the draining of wetlands. While the activity is set in Missouri, the case can apply to any wetland conservation or restoration project. Users can access information regarding l
Floodplains in the field
In this lab, students measure a topographic and geologic cross-section across a floodplain by simple surveying and augering techniques. Placing the lab context for use, this site provides learning goals and skills, equipment lists, teaching notes and materials, assessment recommendations, and links to further references and resources.
