Parkwood Elementary School fourth-grader Christian Calderon leaps off a diving board at the Jeffersonville Aquatic Center on Thursday morning. Calderon and the rest of the student body from the school were rewarded with a day at the center for clocking the most steps, using pedometers, in the Greater Clark County Schools Fitness Challenge. This is the third year in a row that Parkwood has placed first in the challenge, although this year they tied with Bridgepoint Elementary School.
