1. The purpose was to see what it felt like to have asthma or bronchitis. These conditions limit someone's breathing, and the straw limited our breathing in this experiment.
2. Running was a a lot harder than sitting or walking. Our muscles needed more oxygen to keep our muscles healthy while moving. The straw only let us have so much air to get oxygen from.
3. Our breathing gets quicker and heavier as we get move active. They change because our muscles need more oxygen too keep moving.
4. I think that it made my breathing harder because the hole in the straw was so small that it let the slightest bit of oxygen into my lungs. It made me feel like I couldn't breathe because of the limited oxygen intake.
5. Breathing through the thin straw made it much harder to breathe because it allowed a fraction of the air in the wide straw through it. It was so different because of the size.
6. The thin straw allowed only a little bit of air through, so it would not be healthy to breathe through it for a long time. It wouldn't give us as much oxygen as we need.
7. We weren't supposed to breathe through the thin straw for a long time, so walking or running with it would be very dangerous. Our muscles wouldn't work well and we eventually wouldn't get enough air to breathe.
8. It would be so hard to do any physical activity because you could pass out or lose your breath. It would be very scary because you know that if you aren't able to breathe very well, you could not be able to breathe, which you could die from.
