One of the most important ways that individual citizens become involved in the federal judicial process is by serving on a jury. Jury service is one of the few legal responsibilities citizens in the United States have to their government. Though some people complain about the imposition of serving on a jury, many find that their service gives them unique insights into the judicial process and an unusual opportunity to deliberate with others on weighty questions of law and evidence. With this lesson plan, students learn the difference between a trial jury and a grand jury and complete a brief activity that tests their understanding of juror qualifications and exemptions. The lesson provides an overview, educational objectives, links to both civics and social studies standards, materials needed, handouts, and step-by-step classroom procedures. (BT)
