More than half the students enrolled at Chapman Intermediate School paid $10 each to participate in "Chapman Hearts for Sidney." With the addition of concessions and raffles, the event raised more than $10,000 for the Sidney Elizabeth Stewart medical fund at Bank of America. Sidney Stewart, a sixth grader at the Woodstock school, was undergoing radiation treatment for brain cancer while nearly 700 fellow students danced and frolicked around the gym to show their support for her.
