• If you passed Harrison's gym on the morning of February 15th, you would have heard lively music, and seen enthusiastic 4th graders moving through various stations, including jumping rope and hula hooping - all for two very special causes.  One, to keep themselves healthy and strong by exercising.  And Two, to help other people become educated and have the resources available to them so they can have healthy hearts too.  It's all part of the annual "Jump Rope for Heart" day, in which all donations from the students (and their friends and families) go to the American Heart Association.
