Organized around the theme of influencing public opinion, this booklet provides teachers and lawyers with classroom materials for elementary grades K-3 (Level A), intermediate grades 4-6 (Level B), middle school grades 6-8 (Level C), and high school grades 9-12 (Level D). In addition, each level contains pages for the lawyer (marked by the scales of justice), the teacher (an apple), and the student (a pencil). The booklet contains lesson plans, activities, a public opinion poll, and an evaluation form for use by lawyers implementing the materials. The lessons and activities ask students to investigate the meaning of public policy, how public policy is shaped in the United States and their communities, and the various ways they might influence public policy. The inside front cover provides tips for lawyers preparing classroom presentations. (TSV)
