This series of educational activities is intended to help teachers communicate basic scientific concepts related to global warming and the greenhouse effect to students grades 7-10. Seven sessions provide laboratory activities, simulations, and discussions that can be used to improve student understanding of a number of important scientific concepts, including the molecular model of heat, ways in which energy is transferred, how objects attain a stable temperature, and the structure of the atmosphere. Activities encourage students to apply scientific knowledge to considerations of the social and ecological consequences of global warming. Section titles are: (1) "Introduction"; (2) "Time Frame"; (3) "Session 1: What Have You Heard About the Greenhouse Effect?"; (4) "Session 2: Modeling The Greenhouse Effect"; (5) "Session 3: The Global Warming Game"; (6) "Session 4: Detecting Carbon Dioxide"; (7) "Session 5: Sources of Carbon Dioxide in the Atmosphere"; (8) "Session 6: Changes On Noua's Island"; (9) "Session 7: The Worldwide Effects of Climate Change"; (10) "Session 8: World Conference on Global Warming"; (11) "Going Further" (nine extension activities); (12) "Behind the Scenes" (background reading for teachers); (13) "Resources" (33 entries); (14) "Literature Connections" (10 fiction and non-fiction); and (15) "Summary Outlines."
