Tammy, a 10 year-old girl, is normally active for her age, participating in her local soccer club (playing goalie) and swimming breaststroke on her country club’s swim team. Lately she has been experiencing pain in her left knee. The problem involves continuing problems resulting from pain in her knee, and 2 visits to a physician. The first visit to the physician is the result of the chronic pain, while the second is due to an culminating incident at the swimming pool. Students are walked through a two-part PBL exercise that investigates problems that may occur during bone development in an overweight, but normally active pre-pubescent girl.
