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. The activities in 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. Each activity includes procedures, sample student record sheets, extensions, and references.
