Today we will be using a spirometer to measure the maximum amount of air we can forcibly exhale from our lungs - aka measuring our vital capacity.
Your blog post should include evidence of your spirometer reading (a picture if possible).
Answer the following questions:
1. How does your vital capacity compare to others in the class? Describe some reasons why you think your vital capacity is what it is. Why are the highest and lowest vital capacities the way they are?
2. How much air is in a usual breath? Why are our breaths the volume that they are?
3. How is the mechanism of exhaling forcefully different than a usual exhalation? Why would practice at this via exercise/instrument playing/singing make you better at it?
