Measuring Lung Capacity Objective: To measure your lung capacity and see how it is affected after exercise. Research question: How is lung capacity affected at rest and at the end of a physical activity test Hypothesis: The participant's lung capacity after performing physical activity will be less than their resting lung capacity, increasing balloon volume when inflated due to the individual's lack of oxygen. Independent variables: size of the balloon used to perform the tests, size of the lungs of the student being tested. Dependent variables: student lung capacity, balloon circumference, volume, radius, and diameter. Materials: 1 balloon for each student tested Tape measureStopwatch Procedure: Part 1: Inhale normally and exhale forcefully releasing the air in the balloon. Measure the circumference of the balloon using the tape measure. Record the results Inhale forcefully and exhale forcefully releasing the air in the balloon.Measure the circumference of the balloon with the tape measure and record the results.Part 2:6. Saute for 1 minute and repeat steps 1, 2 and 3.7. Jump for 1 minute and repeat steps 4 and 5. Overall Results: Part 1: (Rest) Students: (Circumference of the globe) Normal inhalation/Forced exhalation (Balloon circumference) Forced inhalation/Forced exhalation 138.1 cm 50.9 cm 232.5 cm52.2 cm324 cm56 cm447.5 cm61.5 cmAverage: 35.5 cm55.15 cmPart 2: (after jumping for 1 min.)

One of the biggest hurdles was getting the results for the diameter, radius and volume of the balloon as there was a lot of confusion with the formulas and results, forcing operations to be repeated multiple times to get the correct results. To improve the practice, testing the experiment would be of great help to ensure that the results are even more accurate.
