Teacher Name:

Subject:
 PE and Health

Topic:
 To learn more about how oxygen is needed for exercise and as fuel for our body.
Content:
 When students arrive, have them sit on the floor in the center of the gym to explain today's activity. Once seated, talk to them about the different parts of their body, the heart, lungs, and other areas. Explain that inorder for you to exercise you need to have your heart, lungs and blood working together to fuel oxgen to all of your important body parts. Explain to them that today they are going to each become a blood cell and fuel the body with the necessary oxygen it needs. Next show the students the path that the blood cell will take to fuel the body parts. They will travel to the Lungs where they will pick up a paper plate, representing a molecule of oxygen. They will then take their paperplate and travel through the pathway of the heart to get to the appropriate body part it goes to. They will know what body part to take the paper plate to based on matching colors of the plate to the color on the bag. After they drop off their molecule of oxygen you can either have them preform an exercise at that "station" or they can just travel back through the heart to the lungs to obtain more oxygen and continue refueling the body so that they can continue exercising. Example exercises are when they arrive at the station for "arm mucles" they can do 3 push ups, or when they arrive to the organs, they can take three deep breaths, etc. Once all of the paper plates have been distributed to all the stations, the activity is over. Instruct kids to have a seat on the floor and rest once they have used up all of their oxygen exercising. At this time you can talk to them about the activity. What happens when you started working harder? Did you use more oxygen, did you get rid of it faster or slower? Why was it important to get back to the lungs to get more oxygen? What does your body need to preform exercise? If needed for more time, you can call out each station and see if the children can remember the exercise that was preformed at that particular station.
Goals:
 To have students understand and experience the concept that when we exercise our bodies work harder. This makes our hearts beat faster requiring more oxygen that causes us to breathe harder.
Objectives:
 Students will be able to generalize basic concepts of the pathway of oxygen within the heart to vital organs and additional parts of the body for fuel.
Materials:
 50-75 Paper Plates (Color Coated 5 colors), Signs (Lungs, Heart, Leg Muscles, Brain, Organs, Arm Muscles), 5 Paper Grocery Bags (one for each station), Cones, and Masking Tape.
