One of the major goals of environmental education is developing students with positive environmental ethics and motivated to take desirable environmental actions. Research indicates that attitudes and behaviors of individuals are frequently modeled after the attitude and behavior of others. Since most youth spend 6 to 7 hours per day in school buildings, a coordinated school environmental program that focuses on preventing and solving environmental problems at the school site can provide an excellent model of attitudes and behaviors for young people to emulate. Developing and operating a school environmental plan can be an important part of a school environmental education curriculum. This digest identifies several environmental concerns that should be included in a school environmental program. Problems emphasized include radon, drinking water, asbestos, and sick buildings. Ways to begin a school environmental program are suggested. Three sources of additional information are listed. A list of 13 references is included. (CW)
