An exchange program is described in which two groups of high school science students, one from Long Island, New York, and one from upstate New York, visited each other's school districts for three days to broaden their experiences with different physical and geological surroundings. The inland group of students was exposed to marine geology and the coastal group experienced mountain geology and ecology. It is proposed that the National Science Teachers Association (NSTA) act as a broker to arrange additional exchange programs of this type. (MH)
