This curriculum and classroom activity guide considers evidence gathered in answer to questions concerning global environmental change. It describes methods that biologists, chemists, geologists, meteorologists, and physicists use to gather and interpret their findings. The activities and approaches in this guide were developed to meet the skill levels and learning styles of a diverse student population. The narrative section provides background information on the subject and includes references in the form of icons that refer to relevant activities in the second section of the book. The activities section provides 14 detailed exercises that illustrate ideas set out in the narrative. These hands-on activities represent various disciplines including animal biology, chemistry, geology, meteorology, physics, and plant biology. They list objectives, estimates of duration of activities, extended background information, introductory exercises, procedures, and useful discussion points. A teacher's guide that provides additional information accompanies each activity. The third section of this book includes an overview of scientific inquiry and easy extension activities. An annotated bibliography contains detailed descriptions of books, teacher guides, and Internet resources that relate to global change research. (JRH)
