After this activity, students should be able to: Each TeachEngineering lesson or activity is correlated to one or more K-12 science, After each person has taken a turn, tell the students that we will be measuring their own lung capacity and testing to see if there is a correlation between their lung capacity and their height. It is possible to inhale and exhale more forcefully - the maximum amount of air moved in and out of the lungs is called the vital capacity, which is the amount of air a person can expel from the lungs at maximum inhalation. Can they demonstrate on their models what has been done to help people with respiratory problems? bronchi: Two large tubes connected to the trachea that carry air to and from the lungs. - Inhale normally and then exhale normally into Review their answers to gauge their mastery of the subject. Lung Capacity: Is There a Difference in Athletes and Non-Athletes? Suggest a way you could measure a persons. within type by subtype, then by grade, etc. Capacities, such as Total Lung Capacity (TLC), refer to two or more volumes combined (Figure 7.1). status page at https://status.libretexts.org, What is the difference between tidal volume and vital capacity? Accessed May 23, 2006. https://en.wikipedia.org/wiki/Respiratory_system. WebHypothesis: Because a male can hold larger amounts of air within their lungs than a female, the diameter of a male blown balloon would be bigger than the balloon blown by a female. In this experiment we tested to find a correlation between height and lung capacity. Thanks for your feedback! WebEstimated Vital Capacity Research has shown that the capacity of a person's lungs is proportional to the surface area of his body and his height. Activity Level All rights reserved. Each subject inhaled as much as they could and then exhaled into a balloon as much as they could. The VC averages approximately 50 mL/kg in normal adults. Cole, Joanna & Degen, Bruce. They will measure the circumference of the balloon they have blown up with the measuring tape. Engineers use models to study complicated processes and better understand them. It definitely helped that we had stretched out the balloons before giving them to the students. Biology In Elementary Schools is a Saint Michael's College student project from a course that ran between 2007 and 2010 and fully described in this book chapter. WebSpirometry. (Grades Compare your subjects vital capacity and variables listed (height, weight, sex..etc). This page was last modified on 22 November 2009, at 14:01. Make graphs of vital capacity vs. time for each participant. This also decreases the pressure on your lungs so the air will flow in from the outside. This activitiy will help students to gain a better understanding of their lungs and how they work. WebResearch has shown that the capacity of a person's lungs is proportional to the surface area of his body and his height. Our team of volunteer scientists can help. Doing this makes the data more reliable. Rank in order from MOST effect (1) to least effect (5), The weight of the person The height of the person, The sex of the person The age of the person Activity level. Record the volume of water that was displaced. Figure 3. Which factor(s) have the most affect a persons vital capacity? Body surface area equals the square root of a person's height (in centimeters) multiplied by their weight (in kilograms). 2. What is the average change for each of the two groups? A model of the lungs. The Magic School Bus Inside the Human Body.

And for a 40 year old (a=40), V=3.6 liters, etc all the way up to an 80 year old (a=80) with a vital lung capacity of about 2.8 liters. While performing the experiment, our group came across one difficulty we did not forsee. As you pull down on the bottom balloon, the volume inside the bottle increases and pressure decreases. Pull the diaphragm (balloon) down (that is, away from the lungs) in order to inflate the lungs. In our experiment, however, we'll be using two methods of measuring lung capacity that we can make at home: the balloon method and the water displacement method. Investigation: What Factors Affect Lung Capacity? 3. How might an athlete's vital capacity compare to a non-athlete? When printing this document, you may NOT modify it in any way. Repeat (either step 2 or 3) so that you have three total measurements. WebThe average adult is about 170 cm tall (h=170). The amount of air that you move in and out of your lungs while breathing normally is called TIDAL VOLUME. How does their vital capacity compare to athletes? Based on your limited data, which factors had the GREATEST impact on tidal volume. Consult the rules and regulations of the science fair that you are entering, Engineers have developed an artificial lung to help people fight infection.
