The students, all from the Philadelphia School District, are part of the Healthy Dragons, a youth team formed a decade ago to promote active lifestyles, to give students lessons in teamwork, and to show children what they are capable of. The Philadelphia Flying Phoenix, a competitive dragon boat team, sponsors the Healthy Dragons, and the school district provides support, but the bulk of the $15,000 it takes to run the kids' short spring season comes from grant funding.
