  1. How Age Affects Lung Recovery By Madison Snider Grade 9

  2. Problem How Does Age Affect Lung Recovery?

  3. Research • Total Lung Capacity: maximum volume to which the lungs can be expanded with the greatest possible effort • How age affects lung recovery and found that a person’s total lung capacity (TLC) increases until puberty where it reaches its height. From there on, the TLC begins to decrease. • How exercise affects lung capacity and found that exercise creates a larger need for oxygen in the lungs so in order to obtain enough oxygen, lung capacity increases when a person exercises. • Breath out is known as tidal volume • Other factors that may affect lung capacity: whether a person smokes or not, amount of a exercise a person performs, and the health of a person

  4. Hypothesis • The hypothesis was: if there will be an evident difference between the lung capacity of younger volunteer compared to older volunteers, then the younger volunteers will have a quicker lung recovery.

  5. Materials • 16 Volunteers • Lung Capacitor • Computer (with logger pro application)

  6. Procedure • Sterilized, disposable mouth cover is placed on the lung capacitor • Volunteer exhales into the capacitor and lung volume is recorded and saved. • Volunteer performs the 10 jumping jacks. • After the exercise, volunteer exhales into the capacitor again and the lung volume was again recorded and saved. • Percent change was calculated • Procedure repeated with each volunteer

  7. Variables Used • Constants: Time, Temperature, Lung Capacitor, Computer, Exercise • Controls: Base Lung Volume • Independent: Age of Volunteer • Dependent: Trial Lung Volumes

  8. Lung Recovery Data Teens Adults

  9. Lung Recovery Rates Percent Change (%)

  10. Conclusions • The hypothesis was that if there will be a evident difference between the lung capacity of younger volunteer compared to older volunteers, the younger volunteers group will have a quicker lung recovery. • This hypothesis was not supported because there was no significant difference between the rate of lung recovery in the younger volunteers and the older volunteers. • The ways this experiment could have been improved include using more volunteers, having a larger range of age groups, and/or having the volunteers perform more jumping jacks

  12. Thanks! I would like to thank all my volunteers for being apart of my experimentation and I would also like to thank all my sources of information. Thank you for listening! If you have any questions I’d be happy to answer them!
