Muscles, Lungs, and a Whole Lot of Heart: Week 2 (July 8-12) Different athletes have different skills, but all Olympians use their muscles, lungs, and heart. Campers will make movable models of lungs (that seem to breathe), hearts (that they can pump), and arm muscles (and bones) that they can flex. Campers will also craft miniature sports arenas (with catapults!) for indoor fun, and of course pump their own muscles as they race outside!
