Today in school we were doing an expirement where we were beathing throught straws. The straws, were both different sizes. It was harder to breth through the bigger straw while I was doing jumping jacks, compared to when I was just sitting, and breathing through the smaller straw. I think it was harder because I was breathing harder because of all the motion I was making.             I was harder to breath through the smaller straw while sitting compared to breathing through the larger straw while sitting, because not as much air could through the smaller straw. 
             I learned that it is harder to breath while moving. That happens because you are breathing harder. The harder you breath the faster your body has to work. That means you body has to keep up.
