The greenhouse effect is critical to understanding the basic mechanism of global warming. This session uses two types of models to help students understand the key concept of the greenhouse effect and the role that CO2 plays. Students then analyze data showing sources and quantities of greenhouse gases produced in the United States and worldwide. A materials list, teacher background information, assessment, safety considerations, standards, references, and resources are provided. This book selection also includes the Table of Contents, Foreword, About the Authors, Acknowledgments, Information for Teaching This Unit, and Index.
