Unit I Artifact II: Lung Capacity Lab

A higher vital capacity allows an athlete to hold more air in their lungs, sending more oxygen to their muscles with less work for their body. While they are getting their break, refill the bottle to the top with water. Subtract the final volume of water in the bottle from the initial to get the amount of water displaced, which is equal to the amount of air exhaled. Convert the diameter to volume using the graph and record this on your table. Today we will do an investigation- Science Quest Measuring Lung Capacity. When the balloon is fully submerged I took the bucket with the balloon away from the tray.

Unit I Artifact II: Lung Capacity Lab

Lung capacity can also be measured using a balloon. Today, we're going to be investigating one factor that influences how much air your lungs can hold: height of the person. The chest contains two lungs, one lung on the right side of the chest, the other on the left side of the chest. To deliver oxygen to the body, air is breathed in through the nose, mouth or both. Discussion Questions Was your hypothesis correct? Tidal volume is the amount of air that you move in and out of your lungs while breathing normally. It definitely helped that we had stretched out the balloons before giving them to the students.

Balloon Lungs

How are their results the same or different compared to yours? The resulting volume amount of water that is pushed out is equal to the volume of air the lungs can hold. If you made sure you took a big breath in and breathed out fully then the resulting volume of water you pushed out is equivalent to how much air your lungs can hold. It would be beneficial to give students permanent markers in order to keep them occupied while waiting, but make sure they do not get the marker on their clothes. Hypothesis: It is expected that the solution with the highest concentration of salt will cause more mass loss to the pieces of potato. If you did, explain how. Nice Job on bringing this idea to the public eye. The water will start pouring out of the bucket and into the oven tray.

Science Quest: Measuring Lung Capacity

Let's test your lung volume to find out. Calculate Lung Capacity The bonus in this science lab is the math that kids get to do! Take a deep breath and then exhale into the balloon. As for reason to measure? I plan on doing this for my kids yearly as an incentive to stay away from smoking. Do you think you made any mistakes? You can check out an easy experiment about lung capacities and blowing up balloons by going to this. Use a clean and dry plastic bottle. The same level of precision number of decimal places is used.

Next, use the radius to solve for volume of the sphere in cubic centimeters using the formula: Use radius to solve for volume Divide this number by 1000 to get your answer in liters. While performing the experiment, our group came across one difficulty we did not forsee. I ask them to take in the deepest breath they can. Then I situated the bucket in the center of the tray. Allow each student to make a conclusion. Based on these lab results, our hypothesis is mostly true. Dry with a paper towel.

Record each trial and then average the three capacities measured. If your volunteers are struggling to blow up the balloon in one breath, have them blow up the balloon before the experiment to stretch it out. Also, if not detailed in table above, include details on how to keep the controlled variables constant and how many times to repeat the procedure. We then used a lung volume graph in order to transfer our measurements into cubic units of lung volume. I believe that making the graph to show the results of the class helped the student's to visualize the correlation between their height and their lung capacity. This is evident when students: a. Have your volunteer hold the bottle in the water.

Probably about 18 or 20 years old. As you breathe out through the tube, the air from your lungs takes the place of the water in the bottle. If you rearrange this equation to solve for the radius, you get: Use circumference to solve for radius 12. Give the volunteer a 2-minute break between trials. Wrap a string around the center of the balloon. Do children, teenagers, middle age adults or seniors over 65 have the best lung capacity? Oxygen is vital for muscles to work properly.

Q & A: Balloons and Vital Lung Capacity

Students will then create a hypothesis about lung capactiy and height. Before each new volunteer, clean the opening of the tubing: in the small cup, pour half vinegar and half water to dilute the vinegar. For the original experiment, teachers had an already created balloon dome to represent a diaphragm. Therfore, our hypothesis states that the larger a person is the higher lung capacity that person will have due to growth and development. We are grateful for your outstanding contributio. Think about if you were a detective interviewing suspects about a crime. Did the numbers match what you thought would happen? See more ideas about Lungs, School projects and Science Projects.

This picture or diagram can be annotated to illustrate how the variables were specifically involved in the procedure. Raw data Make a table to organize the data collected while carrying out the procedure. If we were given more time we could have tested to find a correlation between lung capacity and other variables. Have students create faces on their balloons with permanent markers while waiting, but make sure they do not get any marker on themselves. This was unsanitary, for the student had left their saliva on the balloon.

Visit for more in depth information Student worthiness This experiment has been tried and is trusted. Dependent variable Volume of air in a balloon as measured by the displaced from a bucket In order to control my depend variable I use a tray to measure the amount of water displaced from the bucket, and from there measure their lung capacity. You will be using the diameter of a balloon and the graph shown to estimate your capacities. How much air can you hold in your lungs? The Vital Capacity is the volume of air that can be forcibly expelled after the deepest inhalation. Feel free to discuss the results with your kids to help them form their thoughts. Next, fill the graduated cylinder with 50 milliliters mL of water.
