Students today cannot know what it was like to live under the early threats of nuclear war, but some may recall the radioactive decay in Okuma, Fukushima, Japan when a March 11, 2011 tsunami caused a catastrophic accident at the Fukushima nuclear reactor.  PBS LearningMedia has educational resources from two powerful premieres that aired this week: The Bomb and Uranium: Twisting the Dragon’s Tail. The Bomb features accounts from the men and women who witnessed the birth of the atomic age; Uranium delves into the mysteries of one of the Earth’s most controversial elements.
