On A Quest To See The Light
Edith Widder has been exploring the deep sea for thirty years. When she descended for the first time, she turned off the lights of her submersible hoping to see marine organisms that make light--bioluminescent animals. Widder says she wasn't prepared for the light show she encountered and has been building tools to document bioluminescence ever since. (3:46)

Students will identify ways that they use and waste natural resources, and they will explore ways that engineers interact with natural resources.
American Soldiers in the Philippines Write Home about the War
During the U.S. war in the Philippines between 1899 and 1904 (which grew out of the Spanish-American War that had erupted in 1898), ordinary American soldiers shared the nationalist zeal of their commanders and pursued the Filipino "enemy" with brutality and sometimes outright lawlessness.

An anti-imperialist movement, which rejected annexation by the Uni

In this 1970 interview with historian Herbert T. Hoover, Amos Owen, Mdewakanton Sioux tribal chairman, gave a mixed verdict on the Indi
"I Glanced Up--The Statue of Liberty!": Emma Goldman Describes Her Deportation in the Era of the Red
After World War I, a "red scare" gripped the United States. One reflection of this climate of hysteria was in the "Palmer raids" on radicals. Striking without warning and without warrants, Attorney General A. Mitchell Palmer's men smashed union offices and the headquarters of Communist and Socialist organizations.
