This classroom activity explains how clouds and pollution in the atmosphere are important to climate, and the need to study whether pollution may be changing Earth's climate in undesirable ways. It introduces NASA's Multi-angle Imaging SpectroRadiometer (MISR) mission. The activity includes building a MISR-lite model to demonstrate how looking at the same thing (i.e., Earth's atmosphere) from different angles produces a 3-dimensional effect that gives much more information than just viewing it from one angle and helps scientists establish a baseline of information about current conditions in the atmosphere. The activity was originally published in Technology Teacher, a magazine published by the International Technology Education Association (ITEA).
