In class today we were doing an expriment with breathing and straws. We had 2 different tpyes of straws one was a wider straw and the other was a thin straw. Some of the activites for the wide straw was Sting in our chair, Walking around the classroom and Jumping jacks, the activites for the thinner straw were Siting in our chair. Some of the activites were hader to do then the others because we were breathing through a hole the width of your pinkie.Breathing through the wide straws made it a little easier to breathe through because it was a bigger hole to breathe through. Breathing throught the thin straw was harder then breathing through the wide straw because it is a smaller hole to breath through. I thought the reason why my teacher asked us to breathe through the thin straw for only 20 seconds because if we did it for a minute we would become light headed from not enough oxgen flow. Breathing changes when you become more active because your heart is beating faster and all of our other body parts need more oxegen to keep them moving properl
