This Oxygen Cycle lesson plan also includes:
Students run clockwise around a track in the gym, pretending they are the blood that carries oxygen through the body. They go to the "mouth" station where they take three breaths and pick up an object that represents oxygen. Students then run to the "heart" station and contract their whole body, pretending to be a heart. They then run to the "muscle" station where they put their beanbag into a bucket and perform a designated exercise.
