Examining Lung Capacity and Age

Medium
Examining Lung Capacity and Age | Science Fair Projects | STEM Projects
Ever wonder how your lungs change as you age? This project will explore the relationship between lung capacity and age.

Hypothesis

The hypothesis is that a person’s lung capacity will increase until they are in their 20’s, after which their lung capacity will slowly decline as they grow older.

Method & Materials

You will need to gather 10 boys and 10 girls aged between 8 to 12 years old, 10 boys and 10 girls aged between 13 to 20 years old, 10 men and 10 women aged between 21 to 35 years old, 10 men and 10 women aged between 36 to 50 years old, and 10 men and 10 women aged between 51 to 65 years old. You will also need 100 balloons, 2 wooden blocks, 100 laundry clips, and 1 ruler. Each participant will take a deep breath and blow a balloon, and the size of the balloon will be measured using a ruler.

Results

The results of this experiment showed that male participants had a larger lung capacity compared to female participants, and participants from the age group of 21 to 35 years old had the largest lung capacity compared to other age groups.

Why do this project?

This science project is interesting because it explores the relationship between lung capacity and age, which is something that many people are curious about.

Also Consider

Variations of this project could include comparing the lung capacity of smokers and non-smokers, or comparing the lung capacity of athletes and non-athletes.
