For about five weeks this summer, students from 37 middle schools researched how epidemics shape society. As the culmination of their studies, the children presented their findings to parents and friends on Aug. 13 inside the Vegas PBS Studios, 3050 E. Flamingo Road.

The showcase was part of the Alexander Dawson Foundation's Center for Excellence in Teaching & Learning, which sponsors a summer enrichment program for high-achieving students. The program is free and is open to seventh- and eighth-graders each year. Kevin Cloud, the foundation's executive director, brings in teachers, authors and professionals from around the U.S. to instruct the participants.
