A series of nine lessons that can be used in any order, this booklet is intended to help teachers and students discuss and analyze the issue of terrorism in the United States. The lessons cover a range of important issues appropriate for social studies classes, and contain readings, discussion questions, and interactive activities. The first lesson presents an overview of the Oklahoma City (Oklahoma) bombing and corresponding issues. The next seven lessons are grouped into three issue areas: responses to terrorism, free speech issues, and the prevalence of conspiracy theories in U.S. society. The final lesson, appropriate for use by teachers in all curriculum areas, models a civic participation process that encourages students to take a hands-on approach to addressing community problems. The materials invite student participation in a variety of activities such as directed discussions, small groups, simulations, role playing, and interaction with outside resource persons. Student handouts are appended. (TSV)
