Atmospheric Detectives. Atlas 2 Teacher's Guide with Activities.
National Aeronautics and Space Administration, Washington, DC. Educational Affairs Div.
As part of the National Aeronautics and Space Administration Mission to Planet Earth, ATLAS 2 will help develop a thorough picture of the Sun's output, its interaction with the atmosphere, and the well-being of Earth's middle atmosphere. This middle school level guide probes the connection between the activities of scientists and the observable world of weather and climated. To do this, the guide is divided into four sections. The first section, "Case History: What ATLAS 1 Discovered" summarizes the findings of the ATLAS 1 Spacelab/Shuttle flight of March 1992. It links that mission with the science goals of ATLAS 2 and future flights. The second section "The Search: What ATLAS 2 Scientists Investigate" delves into the invisible world of protons, neutrons, and electrons to explain the fundamental mechanism of absorption of ultraviolet radiation by ozone and the destruction of ozone by chlorofluorocarbons. The third section "The Motive: How Solar and Atmospheric Changes Might Affect Climate" explores the relationship between solar activity and weather and climate. The fourth section "The Method: How Atlas 2 Investigators Make These Measurements" studies the remote-sensing techniques of spectrometry and limb sounding. It also involves students in ground-truth studies and exercises that emphasize the importance of mathematics and precise measurement. (PR)
