Relation between chest volume and vital capacity.

... Lab on Relation between chest volume and vital capacity Research question: Is there a correlation between the Vital capacity of a person, the flow rate and his/her chest volume? Hypothesis: There is very little correlation between Vital capacity, flow rate and chest volume. Tools: Vital capacity measurer, flow rate meter, water, carton cylinders, Method: The chest volume was measured by measuring the distance between: 1. The 2 shoulders 2. Shoulder to the lowest rib 3. the thickness of the chest (2 bones located in the shoulder area) Then these three measurements were multiplied together so as to find out the chest volume. Then the Flow rate (how much one can breath in per minute) was measured with a flow rate meter. It is an object mainly used to predict asthma attacks, it tells how many liters of air can be breathed in per minute. The way it is used is that one blows in it as hard as possible,
