Breathing Through Straws

Today we did a breathing through straws experiment we used two different straws. We used coffee stirring straws as the really thin or small straw. And then we used just a regular drinking straw as the second straw. One of the really hard ways to breath through the straws were doing jumping jacks with the normal sized straw and then it was really hard to breath through the smaller straws while we wrer sitting down. It was hard because, the smaller straws make you breath deeper and use more air. Then using the wide straws caused deep breathing after the jumping jacks in place. Breathing through the thin straw was so different then doing it with the wide straw because it could only hold so much air at a time. Changes do happen when you are breathing through the straws while doing different activities because depending on what you do it makes you use more air to breath through the straws.
