By the early 1900s, many Americans were calling child labor child slavery and were demanding an end to it. Lewis Hine, a New York City schoolteacher and photographer, believed that a picture could tell a powerful story. He felt so strongly about the abuse of children as workers that he quit his teaching job and became an investigative photographer for the National Child Labor Committee. Hine traveled around the country photographing the working conditions of children in all types of industries, including coal mines, meat packing houses, textile mills, and canneries. By 1916 Congress passed the Keating-Owens Act that established child labor standards, and by 1920 the number of child laborers was cut to nearly half of what it had been in 1910. This lesson relates to the First Amendment rights, including freedom of the press and right of the people to petition the government for a redress of grievances. The primary lesson sources are 16 Hine collection photographs of children working. It correlates to the National History Standards and to the National Civics and Government Standards. The lesson presents historical background of the era (with three resources) and suggests diverse teaching activities for classroom implementation, including brainstorming, photograph analysis, creative writing, class discussion, and interactive computer activity. A photograph analysis worksheet and the Hine photographs are appended. (BT)
