Measuring Lung Capacity

Measuring Lung Capacity | Science Fair Projects | STEM Projects
How is your lung capacity? Find out by blowing up balloons and measuring how much air you can put in them.


The hypothesis is that people have different lung capacities.

Method & Materials

You will give identical balloons to pairs of students and have them blow up the balloons as much as possible with one breath.
You will need 6" and 9" balloons, a cloth tape measure, paper, and a pen or pencil.


The results of this experiment show that people do have different lung capacities.

Why do this project?

This science project is interesting because it allows students to explore the differences in lung capacity between people from different backgrounds.

Also Consider

Experiment variations to consider include having students run in place for 2-3 minutes before blowing up the balloons and having students blow up the balloons with multiple breaths.
