Hundreds of young, would-be scientists gathered today at Temple University for the annual George Washington Carver Science Fair. Representing middle and high schools throughout the city, these students, in grades 7 through 12, showcased a wide variety of projects for the panel of judges. “I don’t expect all of them to become scientists,” said Thomas Anderson, who co-founded this event 34 years ago. “But I expect them to become aware of science because science controls our lives from the day we come to this earth to the day we die.”
