Straw Experiment

Today in school we learned about breathing. We breathed through a straw and did different activities. I thought that it was harder to do jumping jacks with a straw in your mouth then regular breathing it wasn't that hard to walk around the room with a straw in your mouth. Once you got the little straw it got hard to breath even without walking around the room. Breathing through the wide straw was hard because it isn't as big as your mouth and it can't fit as much air in your lungs as your mouth can. Breathing through a small straw affected me differently then the big straw because not a lot of air could fit through the thin straw so I could barely breath. Once you start breathing normaly you have to pant because you didn't get enough air. Your breathing changes when you get more active because you need more oxigen to get to your cells which comes from your lungs so the heart can pump it but when you breath fast it doesn't mean that your heart beets fast.
