This study guide is designed to help students learn to use science skills to solve biological problems, learn to apply knowledge about biology in their own lives, and learn to communicate with others about biology. The activities in this guide use information related to each chapter in the 1987 BSCS Green Version textbook. Students can use the activities before, during, or after their study of the chapter. There are 99 activities and exercises related to the 25 chapters of the textbook. These paper-and-pencil activities direct students to make observations, collect data from research sources, draw models and diagrams, and interpret and draw graphs. This teacher's edition provides possible student responses. (CW)
