"Genesee Had Railroads": Kenneth Platt Recalls the Importance of the Railroad to Late Nineteenth-Cen
The penetration of the railroads into the West in the late nineteenth century had a profound impact on local economies. For a period of ten years in the 1880s the Latah County, Idaho town of Genesee experienced this phenomenon. One town boomed while its neighbors languished in economic isolation, largely as a result of the rail station in Genesee. In this oral history interview, Kenneth Platt described the railroad's impact on Latah County.
Dissatisfied With the Lives They Live: Farm Women Describe Their Work in a 1913 U.S. Department of A
Statistics on women's work in the early 20th century were invariably misleading: most women worked but only a minority were formally in the wage labor force. Nowhere was the discrepancy between the domestic ideal and the reality of women's work lives wider than in rural America. In 1913 the U. S. Department of Agriculture decided to investigate and document the lives of farm woman they discovered a vast reservoir of discontent. The report, reproduced here, was culled from letters responding to a
"Sadie's Servant Room Blues": 1920s Domestic Work in Song
Domestic service was the most common category of employment for women before World War II; it was particularly important for black women, who were excluded from most other occupations. By 1920 some 40 percent of all domestic workers were African American--and more than 70 percent of all wage-earning African-American women worked as servants or laundresses. The struggles of domestic workers were sometimes recorded in songs like Hattie Burleson's 1928 "Sadie's Servant Room Blues," a musical versio

Redes Inalámbricas en los Países en Desarrollo (Segunda edición en español)
The book is intended to be a comprehensive resource for technologists in the developing world, providing the information that they need to build real networks. By bringing this knowledge to the outer edges of the Internet, we hope to help jumpstart the construction of vital network infrastructure. Besides the topics included in the first edition, covering from basic radio physics and network design to equipment and troubleshooting, the second edition includes a new chapter dedicated to Voice ove
Views from Windows
This OLogy activity challenges kids to put their imaginations to work in order to gain a new perspective on perspectives. The activity begins by telling kids that how they see the world depends on two things: where you're looking from, and how fast you're moving compared to the speed of light. They are then asked to print one or more of four window frames and fill in each with an illustration that captures the scene's height and velocity. The window frames are: your bedroom window, a speeding ca
How fast do materials weather?
In the activities described on this website, instructors giving a lecture on weathering ask students to calculate weathering rates from tombstone weathering data from urban and rural settings. The Starting Point site includes downloadable teaching materials, information on learning goals and context for the exercise, and links to useful resources and references.
Going Away Party, The
'The Going Away Party,' by Dan Boord and Greg Durbin, is a dramatic work about corruption among Oklahoma county officials. It is based on the true stories of incidents of corruption amongst Oklahoma's elected county commissioners. This segment is from the dramatic 'reenactment,' showing friends and supporters of Burrows, a commissioner sentenced to serve a jail term, at a going-away party.
Floyd Bennett Field: Naval Aviation's Home in Brooklyn
recounts the role of this airport in aviation history and World War II. In 1931, it was among the most advanced airports in the world. From it, early aviators launched pioneering and round-the-world flights during the 1930s. After the Japanese attack on Pearl Harbor, its duties as Naval Air Station New York grew rapidly. During the 1942 U-Boat offensive, it provided air cover for ship convoys embarking from New York.
Paleoclimate: Climate Change Through Time
This site provides access to a spectrum of web-based visual resources and supporting material that can be used to teach students about paleoclimate through geologic time. Visualizations include simple animations, GIS-based animated maps and paleogeographic maps, as well as numerous illustrations and photos. Resources can be integrated into lectures, labs, classes, or other activities about paleoclimate and land cover and land use change over time.
Observe how fossils can form
This website hosts an animation depicting how cast and mold fossils are preserved in the rock record. Users can play, rewind, fast forward and stop the animation at any point in the formation as well as read captions outlining the process. The animation is part of the Earth Exploration Visualization collection.
Backward to the Future
Oral histories not only help us to recall important memories, but when told to children in the form of storytelling, they also provide a connection to the real world and give children a place within their own community. Oral histories help to explain events in one's life while providing an account of the time remembered. In this lesson, students watch a video of a personal history and learn the difference between primary sources and secondary sources of information. They learn how technology and
Draw Your Own Visualization
The purpose of this activity is to learn about visualizations by designing and drawing one. Students draw a visualization based either on their interests and ideas about the world or based on actual GLOBE data. They are asked to justify the design choices they make and to interpret the visualizations of their peers. Intended outcomes are that students learn to identify and communicate important patterns in a dataset by drawing a visualization, and begin to interpret those patterns. Students sele
Large groups of children are likely to scare off mammals, but they can learn to identify tracks to learn more about the animals that left them.

Bioinformatics in the Biology Classroom
This educational journal article addresses the implementation of bioinformatics in the classroom. The author explains how bioinformatics could play a key role for science students pursuing higher education, foster inquiry learning of content that has often been taught in a dry manner, provide the thread that ties classes together, improve biology teaching, enhance the learning of biotech issues and ethics, expose students to real-world science, and significantly help to reform biology teaching a
Your Regional to Global Connection
The purpose of this resource is to identify specifically how one's own region is connected with others, and to discover the interconnected nature of the Earth's regions as systems. Students brainstorm about the nature of connections between their region and others, across oceans and on different continents. On a black-line map of the world, they trace possible pathways of water and wind currents from their part of the continent to other continents, and identify what the wind and water carry. The
