Andrew Marr explores the development and deployment of the first atomic bomb. He describes the moral dilemma faced by the scientists of the Manhattan Project, and the fallout from the detonation of the bomb over the Japanese city of Hiroshima. Warning: Contains some upsetting and disturbing scenes. Teacher notes: Students could write a series of haiku poems (5-7-5 syllables) justifying or challenging the dropping of the Atomic bombs on Japan, or discussing the effects of the bombs. Students could hold a debate to discuss the following motion: 'The dropping of the Atomic bombs on Japan was justified because they brought a faster end to World War Two'.
