This web page is a module for Grades 5-8 on the topic of Earth’s atmosphere. It contains background information for teachers on atmospheric gases and their properties, explains how energy is transferred between the earth’s surface and the atmosphere, and discusses the role ocean currents play in transferring heat. Included are links to seven classroom activities and labs on radiation, conduction, convection, the water cycle, and more. NOTE: A few of the labs involve hot liquids and require close teacher supervision. See Related items on this page for additional resources by the same authors.
