More than 600 Philadelphia public, parochial, charter and home-schooled students in grades 7 through 12 showcased their science and engineering skills at Philadelphia’s largest annual science fair, held in Temple’s Athletic Pavilion. The students competed in more than one dozen categories, including botany, engineering, zoology, mathematics, biochemistry, computer science, medicine and environmental science.

The top three winners from grades 7 and 8, 9 and 10, and 11 and 12 in each category received the prestigious George Washington Carver Science Medal and represent the Carver Fair at the Delaware Valley Science Fair in Oaks, Pa., in April. The students also competed for additional awards and college scholarships.
