Elisa Passarelli, Tom Arrison, Louise Belnay, and others. Developed in collaboration with National Oceanic and Atmospheric Administration (NOAA), Environmental Research Laboratories, Forecast Systems Laboratory (Boulder, Colo.). Washington, D.C.: U.S. Government Printing Office, 1994. Recommended grade level: Global Awareness for Students (GAS): Studies in Climate is a teacher's guide offering 20 activitiesincluding exercises, labs, and demonstrationsthat focus on atmospheric and greenhouse gases and how they may or may not affect earth's climate. Among the activities, students make a model to understand the heating of the earth's atmosphere. They observe air bubbles trapped in ice cubes and compare them to air trapped in a glacier. They test for the presence of carbon dioxide in gas samples by using an indicator, bromthymol blue. Students also design climate models using computer spreadsheets. They examine the social causes of an increase in greenhouse gases by gathering and organizing statistics on population growth, economic development, or natural resources. Other topics addressed in the activities include radiant energy, methane, ozone, and the wide range of impacts that may result from global warming. Global Awareness for Students were originally developed as part of a summer science institute sponsored by National Oceanic and Atmospheric Administration. Limited background information is provided for some, but not all, of the activities. Some of the activities contain short reading sections for students; many require data analysis and graphing. Each activity includes procedures, sample student record sheets, extensions, and references. | |
