This student booklet is part of a curriculum designed for infusion into secondary U.S. history courses to help students explore the purposes of American law. The booklet contains student readings and discussion questions and suggests learning activities. There are five units. Unit 1, "Law in a New World," examines processes used to make legal decisions during the American colonial period. Students compare the consensual process used by the Iroquois Indians with those processes used during the Salem witch trials. Set in New Orleans during the War of 1812, Unit 2, "Patriots and Pirates," involves students in evaluating whether Jean Lafitte was a patriot or a pirate. They apply criminal law standards to actual cases in which Lafitte was involved. In Unit 3, "During the Late Wicked Rebellion," students study about Lambdin Milligan's resistance to the War between the States and learn that the protection of individual liberty is a primary purpose of the U.S. Constitution. In Unit 4 students examine legislation aimed at ending "Child Labor in America." Unit 5, "The Twenties in Turmoil," examines the nature, purpose, and consequences of Prohibition. (RM)
