Lung capacity Test
The purpose of this experiment was to indicate whether or not people who drink more water have a greater lung capacity than those who drink less water
If one drinks a lot of water then they will have a higher lung capacity compared to one that drinks less water
Mouth tube, VO2 machine (spirometer)
Acquire all necessary materials
Use the spirometer to test tidal volume, inspiratory reserve volume, expiratory reserve volume and vital capacity
Record results in a chart
Drink a lot of water
Drink less water

At high altitude, respiration extracts utilizes a high proportion of the overall energy.
Although there is a slight decrease in the work of breathing resulting from the lower density of the air at high altitude, greater volumes of air are necessary to supply enough oxygen to the body from atmospheric air, in which the level of oxygen is reduced.
TV+IRV+ERV=VC 1.5+0.2+1.2=3.2, my actual vital capacity was tested 3.5. This is because when I add my TV, IRV, and ERV the answer is approximate. When I test my vital capacity in the spirometer it is more accurate/exact.
If we were to repeat the experiment again, what I would do to improve it would be to do the test multiple times for more accurate results, I would also make sure the people that are comparing results use the same spirometer incase, the spirometers differ in any way.
