Choir Singers and Lung Capacity

Easy
Choir Singers and Lung Capacity | Science Fair Projects | STEM Projects
Do people who sing regularly have larger lung capacity than non-singers? You recruit 20 participants who are all the same age. Half are choir members with at least one year of experience. The other half are non-singers and non-athletes. Each person takes one deep breath with a nose clip on. Then they blow as much air as possible into a balloon. You measure the balloon diameter with a ruler. Choir members inflate their balloons to a larger size than non-singers. The results also show that boys tend to have greater lung capacity than girls.

Hypothesis

The hypothesis is that choir singers will have greater lung capacity than non-singers.

Method & Materials

You will measure the lung capacity of 10 singers and 10 non-singers by having them blow up balloons and measuring the size of the balloons.
You will need 5 boys and 5 girls age 15 who are in the school choir, 5 boys and 5 girls age 15 who are not in the school choir, 60 balloons, a ruler or measuring tape, and a nose plug or swimmer nose clip.

Results

The results showed that the choir members were able to inflate the balloons to a larger size than the non-singers, indicating that the choir students had bigger lung capacities. It was also found that boys had a bigger lung capacity than girls.

Why do this project?

This science project is interesting because it shows how training can help strengthen our chest muscles and increase our lung capacity.

Also Consider

Variations: The experiment can be repeated by athletes instead of choir singers. Try to repeat the experiment using a spirometer instead of balloons to measure lung capacity.
