The lungs are ridiculously cool organs in our body and it is fairly easy to build a model of lungs. For our preschoolers, it’s a lot of fun and easier to understand a complex topic like lungs by creating a model.

This preschool STEM activity is so much fun and it will be so cool to watch your preschooler’s reaction as they learn how lungs work through this hands-on model.

Obviously, this activity is about science and how lungs works, but it also will work on some fine motor skills and engineering skills as your preschooler helps build the model.

Lil’ Explorers Focus Skills

Science

  • Pose “what” and “why” questions about their surroundings
  • Make predictions and perform experiments
  • Understand 3 of the 5 senses to make observations

Engineering

  • Construct models to represent their imagination and objects in the world
  • Build using a variety of materials in both conventional and unconventional ways

Lil’ Creators Focus Skills

How Lungs Work Template

*Paper Bags

*Straws

*Tape

Step #1

Print and cut out the How Lungs Work Template.

Step #2

Tape two bendy straws together with the bendy edges both facing the same direction.

Step #3

Put a bag over the end of each straw and tape them shut tightly so when your Lil’ breathes into the straws, it inflates the bags.

Step #4

Tape the nose to the top of the straws with enough room for you to breathe into the straws. Tape the mouth below the nose and tape the lungs to the bottom by the bags.

Step #5

Blow in and out of the straws and watch the lungs (bags) inflate and deflate.

Teacher Tip

Conversation is KEY. Be sure to talk about what each material represents (lungs, esophagus/throat, mouth, and nose). Make predications of what will happen when you breathe into the straws and what will happen when you suck the air out. Connect this model to their body.   Have your preschooler take a deep breath and focus on filling their lungs with air, then have them blow out and feel their lungs deflate. Models are a fabulous teaching tool, but the conversation is what makes them effective.
