In August, 1997 student experiment modules both passive and active were flown in a "carrier" which resides in the cargo bay of the space shuttle, Flight STS -85 Discovery. Twenty-seven schools from Charleston and Berkeley School Districts with two additional schools from McCormick, SC and Baltimore, MD are participating in the SEM Program (Student Experiment Modules). The payload will carry 171 passive student experiments representing the efforts of several hundred student teams under the guidance of their teachers. Selected and prepared materials were taken from everyday common elements. These experiments represented the individual concepts of teams ranging in age from kindergarten to eighth grade. Each student submitted five coded samples, one for space flight and four control samples. The control samples were exposed to radiation, cold, centrifugation respectively while one negative control sample was passively stored. When the samples were returned, the students investigated their samples according to their individual research protocols. The results were presented at a student research symposium in April of 1998.
