In class we did a straw experiment were we had to breath threw a straw. As we did more active things it got harder to breath because are hole that we breath threw ( Mouth ) gets smaller so the harder it is to breath. Then we had to try to breath threw a smaller straw and that was the hardest because the hole that we had to breath threw is super small.
