"A Perfect Hailstorm of Bullets": A Black Sergeant Remembers the Battle of San Juan Hill in 1899
The best-known image of the Spanish-American War is that of Teddy Roosevelt on horseback charging with his Rough Riders up San Juan Hill in Cuba. But not only was the role of the Rough Riders exaggerated, it also displaced attention from the black soldiers who made up almost 25 percent of the U. S. force in Cuba. Indeed, the Spanish troops, who called the black soldiers "smoked Yankees," were often more respectful of the black troops than were the white officers who commanded them. Here Sergeant
"Speak, Garvey, Speak!"A Follower Recalls a Garvey Rally
The Jamaican-born Marcus Garvey, a brilliant orator and black nationalist leader, turned his Universal Negro Improvement Association (UNIA) into the most important black organization in the United States in the early 1920s.

In an oral history interview, devotee Audley Moore remembered the Jamaican's defiant behavior at a rally in New Orleans c
"Organize among Yourselves": Mary Gale on Unemployed Organizing in the Great Depression
The Communist-led Unemployed Councils were the first and the most active of the radical movements that sought to mobilize the jobless during the Great Depression. In this interview, which is taken from the radio series "Grandma Was an Activist," relief worker Mary Gale, who was sympathetic to radicals and the jobless, described how she worked behind the scenes to encourage her clients to organize and demand better treatment. The jobless and the poor had few advocates for them, and radicals like
Kate Richards O'Hare's Life as a Socialist Party Organizer
In her autobiographical essay, "How I Became a Socialist Agitator," which was first published in Socialist Woman in October 1908, Socialist Party organizer Kate Richards O'Hare credited her career as a "Socialist agitator" to her youthful exposure to poverty and "sordid suffering." As she explained in this essay, her disillusionment with the church and a talk by labor organizer "Mother"Jones further pushed her toward socialism.
"It Is Entirely the Bolshevik Spirit": Mill superintendent W. M. Mink Explains 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, W. M. Mink, mill superintendent at the Homestead steelworks, testified that the cause of the strike was simple--the infection of "the Bolshevik spirit"among "the foreigners."
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.
The Use of a Piece of Land
The Use of a Piece of Land activity was developed by The Maine State Library. This activity engages students in a practical exercise in land use planning and makes students aware of the positive and negative aspects of land use laws and local zoning ordinances through role-playing. The students represent groups interested in purchasing the same piece of land. Each group must research to devise a plan that is legal and environmentally attractive, and present proposals to convince the current owne
Human Tube, A
Against a background of high-rises and rubble, the image of a young man running across an empty lot is repeated. A sense of urgency builds. Buildings explode and crumble to the ground. A hand-held camera surveys the moving ground. Images are blurred, erased, distorted, replaced, and repeated to create this dramatic short work by Paul Garrin. Dramatic electronic music was composed and performed by Ryuichi Sakamoto.The piece is approximately five minutes in length and was broadcast as a segment of
Kissing Booth, The
Documentary-style piece in which four celebrities (Quentin Crisp -author, Emily XYZ -poet, Joe Morton -actor, Spider -musician) talk about kissing, seduction, relationships, love, sex, and romance in the U.S., England, and South Africa. Speakers muse about the subjects and talk about their own personal experiences. Shots of speakers talking directly to the camera are interspersed with straightforward and computer-enhanced scenes of couples kissing. Approximately 28 minutes in length.
Trisha and Carmen
Burt Barr looks at the performance of 'Carmen' by Trisha Brown at the Teatro di San Carlo in Naples, Italy Scenes include details of the ornate theater, both empty and with the audience stirring in their seats before the performance. Backstage, Trisha Brown speaks directly to the camera and prepares for the show with a makeup artist. In rehearsal clothes, a duet is shown over and over again. A woman treads her way across the space to her male partner, who slowly lowers her to the ground. This sa
Seeing the Invisible
Students will be instructed to make an observation of a flower (tulip) given the one stipulation that they will only be allowed to detect the parts of the plant that are green. Through observation and discussion, students will be led to understand that only seeing parts of the flower leads to an incomplete and even inaccurate understanding of its structure. Students will construct their own knowledge of the Sun emitting light above and below the visible spectrum by using UV beads to detect ultr
Cosmic and Heliospheric Learning Center
This site explores the universe through interactive activities and learning resources such as the question and answer service, Ask a Physicist. Students can also learn astrophysics basics, or find out the history of cosmic ray studies beginning with the Mesopotamian and Egyptian astronomers mapping the heavens, and more.
FoilSim and CurveBall
FoilSim II computes the theoretical lift of a variety of airfoil shapes. The user can control the shape, size, and inclination of the airfoil and the atmospheric conditions in which the airfoil is flying. The program includes a stall model for the airfoil, a model of the Martian atmosphere, and the ability to specify a variety of fluids for lift comparisons. The program has graphical and numerical output, including an interactive probe which you can use to investigate the details of flow around
Introduction to Physical Oceanography
This book is written for upper-division undergraduates and new graduate students in meteorology, ocean engineering, and oceanography. After reading this book, it expected that students will be able to describe physical processes influencing the ocean and coastal regions: the interaction of the ocean with the atmosphere, and the distribution of oceanic winds, currents, heat fluxes, and water masses.
NSF Scrub Club
