"Shooting at People Wasn't Our Bag": One of the Inventors of the Computer Speaks
Who invented the computer? Like many important technological developments, the invention of the computer cannot rightly be attributed to a single person. It is clear, however, that World War II was crucial to the emergence of the electronic digital computer. The first general-purpose electronic computer was the Electronic Numerical Integrator and Computer, the ENIAC, sponsored by the U.S. Army's Ballistics Research Laboratory at the Aberdeen Proving Ground in Maryland and developed at the the Mo
A Mule Spinner Tells the U.S. Senate about Late 19th century Unemployment
Fall River, Massachusetts, mill worker Thomas O'Donnell (who had immigrated to the U.S. from England eleven years earlier) appeared before the U.S. Senate Committee on Education and Labor on October 18, 1883, to answer the panel's questions about working-class economic conditions. An unemployed mule spinner for more than half of the year, he described the introduction of new production methods at the Fall River, Massachusetts, textile factory where he worked as a mule spinner (a worker who tende
A German Radical Emigrates to America in 1885
Labor organizer and newspaper editor Oscar Ameringer the "Mark Twain of American Socialism," as he was often called, was born in Bavaria in 1870 to a cabinetmaker father and a freethinking mother. In this excerpt from his autobiography, If You Don't Weaken, published in 1940, he discussed his decision to emigrate to America in 1885 as a fifteen-year-old "hellion." In America, Ameringer ultimately carved out a remarkable and colorful career as a musician, labor organizer, and especially, an edito
Race and Racism at the 1886 Knights of Labor Convention
The annual convention of the Knights of Labor that convened in Richmond, Virginia, on October 4, 1886, took place in a region riven by racial and political conflict. The convention and the Knights, the most powerful labor organization in late 19th century America, were quickly plunged into conflict over the organization's attitudes toward the question of social equality between the races. A major controversy erupted over whether or not Frank J. Ferrell, a black representative of the Knights' pow
"We Did Not Have Enough Money": George Miller's Testimony about 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, Clairton worker George Miller called the 1919 strike a quest for "a standard American living"--a phrase that was particularly meaningful to the Serbian-born Miller.
"Eight Hours a Day and Better Conditions": Andrew Pido Explains His Support for the 1919 Steel Strik
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, Slavic steelworker Andrew Pido described the discrimination faced by some immigrant workers and how that discrimination - along with long pay and poor conditions--encouraged them to unionize and strike.
Distribution of Active Volcanoes
On this website, Starting Point Teaching Collection explains the Distribution of Active Volcanoes exercise. This worksheet is intended to direct students working independently in a 6-week exercise on volcanoes within an online geology course. The exercise consists of a series of questions plus helpful links and a map. The students collect and plot data, then interpret the results and answer questions about the geologic causes and the human effects of volcanic eruption. The exercise includes indi
Rocks and Weathered Rocks
In this lab, students examine what happens when rocks weather, how different minerals weather at different rates, and what the ultimate byproducts are. This website builds context for lab use, details the learning goals and teaching notes, provides teaching materials and lab assessment recommendations, and additional references and resources.
This field exercise determines the susceptibility of different rocks to weathering, and, using the dates on the tombstones, estimates some weathering rates. Placing the field lab in context for use, this site describes the learning goals, teaching notes and materials, assessment recommendations, and provides links to other resources and references.
Cans and Can`ts of Teaching Evolution
This essay discusses what U.S. public school teachers are allowed to say about evolution and religious creation accounts.

Anges Rebelles, Les
"In six minutes, a conjuring trick combining special effects and the magic of painting enables us to enter the world of Jacques Brissot.

Artist Jacques Brissot is shown adding to and retouching a large-scale collage work, lending insight into his compositional choices and his techniques and methods. Music is by Michel Arich, with Barney Wilen playing saxopho
Project SkyMath is a mathematics module for middle school students, developed by the University Corporation for Atmospheric Research (UCAR). The goal of the pilot project is to demonstrate that acquiring and using current environmental and real-time weather data in middle school classrooms, in ways that embrace the dynamic and the uncertain natures of these data, will promote the teaching and learning of significant mathematics, consistent with the standards set by the National Council of Teache
