This book contains 45 activities suitable for use in secondary science and social studies classes. Except for the first four activities, which are quick attention getters, all the activities are presented in a standard format. Each begins with an introduction, that provides a brief overview of the activity's content and the teaching strategies used. Student learning objectives are listed, as are recommendations for the subject and grade level at which the activity can be used. The time required to use the activity is given, and any materials and preparation needed are described. Step by step procedures are presented. Included are questions that can be used to stimulate discussion, probe the issue, or debrief a discussion or other activity. Finally ideas for extension and enrichment are given. In some cases, additional resources that could be used to enhance learning about the lesson topic are listed. The activities are organized into three major sections. First are starter activities that stimulate awareness about science, technology, society (STS) topics on issues and help students brainstorm, generate discussion, and explore ideas about STS issues. The following two sections present lessons designed primarily for science and social studies classes, respectively. Within each section, the lessons are grouped by common course titles. In one, the science courses used are earth science and environmental studies, life science and biology, chemistry, and physics. In the next section, the social studies courses used are world geography, world history, U.S. history, and civics and government. (Author/DK)
