Lungs for Kids

Whether you are studying the human bod for kids or just learning about your amazing lungs, this lungs model is such a fun, simple human body project for kids of all ages. In this lungs for kids activity, grade 1, grade 2, grade 3, grade 4, grade 5, grade 6, and grade 7 students will be amazed that with a couple simple materials they can make a working lung that replicates how our amazing lungs work to hep us breathe! Whether you are a parent, teacher, or homeschooler – you will love these instructions for how to make lungs with a few common materials. We made this with my daughter as part of her Classical Conversations Challenge A anatomy class. Hands-on science projects just make things come alive for kids and make sense so much better.

Lungs Model

All you need are a few common supplies you probably already have on hand to make your working lungs model for kids:

  • empty, plastic water bottle
  • balloon
  • packing tape

Lungs Model for Kids

First of all, make sure kids know where the lungs are in their bodies, what their important job is, and how they can protect and strengthen their lungs. We watched this simple demonstration to start learning about the lungs.

Then we read some books to dive into the topic a little further.

How to Make Lungs

How to Make Lungs

I started by explaining how the lungs are a bag-like organ used for breathing and even talking. It brings oxygen in the air and then lets carbon dioxide out. We need oxygen for our body to work, without it we will die.  At the bottom of the trachea (tube in your neck) there are two large tubes called the bronchi.  One leads to the left lung while the other heads into the right lung. Each main stem then branches off into tubes, or bronchi, that get smaller and even smaller. Many people compare our lungs to a gree with the trachea being the stem and the brochi as the ever splitting, smaller and smaller branches ending with the tiniest tubes called bronchioles in each lung – you have about 30,000 of these that are the thickness of a strand of hair. At the end are air sacs called alveoli (about 600 million in your lungs) that fill with air without you even thinking about it! Ready to see our simplified lung model in action?

How to Make a Lung Model

Making a workign lung model is super simple! Plus lots of fun too! This project helps kids understand how lungs work, but only demonstate one lung – most everyone has two.

  • Cut bottom off of the water bottle.
  • From the mouth part, push balloon into water bottle, fold the balloon mouth part over the bottle part.
  • Cover bottom with a large balloon that has the mouth piece cut off.
  • Use packing tape to secure all edges.
