Learn About the Heart with Simple Anatomy Lesson for Kids

Simple science experiments are the best and this real heart anatomy lesson is one of our favorites!   So many people think about hearts about the cute romantic icon that has become popular. But the real heart is much different and this simple heart anatomy lesson will teach your child how different they really are.

Learn about the heart with kids with this inflatable heart craft that teaches simple anatomy lessons.
This inflatable heart is a simple working model of a heart.

What Is A Heart?

The heart, the symbol so beautiful, is actually our cardiac muscle and is vital to our survival! It pumps our blood through our body which is what keeps us alive.

If you put your hand on the left side of your heart, I’m sure you can feel it. Bubum, bubum, bubum.

Learning About the Heart

Before making the heart craft, you could do some other cardiac learning activities:

  • Take a toy stethoscope (or real stethoscope if you have one) and listen to the heart beats of each other
  • Let the kids move to the rhythm of a song and afterward let them listen to the heartbeat of their neighbor’s heart
  • Repeat this experiment while relaxing to compare their data – Remember to make a return on their observations and experiments.
  • Read a book about the heart or to find a simple but realistic picture. With my son, we found that there is a vena cava and the aorta coming out of the heart. Then we saw that there are 2 ventricles in the heart , and finally, that there are cardiac veins and coronary arteries of the heart muscle.

Real Heart Anatomy Lesson

My son loves everything scientific, and these days he especially likes his book, Look into Your Body. Since then, he asked me many questions about bones, muscles and how our heart and brain works.

I thought and thought and thought

Then I thought I found the solution!

I finally decided on a lesson: An inflatable heart it will be!

I love the process of creating. Sometimes my ideas end up in a cul de sac, sometimes they just do not work.  Never despair. Each failure leads us to other avenues and who knows?

Perhaps it will be a good or better avenue. I started my process of creative thinking to make a heart with tulle and glue and finished with this inflatable heart.

This is what a real heart looks like.

Supplies Needed To Create an Inflatable Heart

  • A Ziploc bag
  • Two straws (one red and one blue)
  • Two pipe cleaners (one red and one blue)
  • A large red marker to marker
  • A hot glue gun
Our DIY inflatable heart to teach us a simple heart anatomy lesson.
Get ready for this real heart anatomy lesson!

Creating Your Inflatable Heart

First, ask the children to color in red one side of the bag with the red marker.

Our inflatable heart has pipe cleaner veins and straws.

Then have them cut out the pipes cleaners in different lengths. You could leave a picture of the heart close so they can easily refer to it.

With caution, help the child glue his pipe cleaners on the bag to recreate the cardiac veins and coronary arteries.

Note: Make clear to the children that they have to make ONE cardiac vein (blue) and one coronary artery (red). The reason is to be able to recreate the ventricles: the hot glue melts and merge the two sides together creating the ventricles.

All they have to do now is to insert a blue and red straw and zip the bag.

Voila! Their heart is ready to beat the rhythm!

Starting Your Simple Heart Anatomy Lesson

Have the child gently blow into the straw and watch as the heart beats.

There is a little video in my original post that shows my son’ s heart beat.   I love that my daughter is at his side is trying to imitate his brother.

A good example of vicarious learning!

What did you think of the heart lesson?


  1. What a cool idea! I’ve pinned it to remember for anatomy later!

  2. Thank you Tricia! Very much appreciated 🙂 Hope you’ll have fun like we did 🙂

  3. Eric Baldwin says:

    I love that craft, cool idea. My guy is too little for it yet (2) but hopefully I will remember to come back to this tutorial in a few years when he is.

    Hope you and your have a happy Valentine’s day!

  4. Three ventricles? The heart has two ventricles and two atria – not quite sure what you are meaning by three ventricles….. cool idea of a beating heart though!

  5. Make your journey complete with learning more about the heart! THANKS!

  6. Deb Shehane says:

    What great ideas!

  7. 2 ventricles and 2 atria.

  8. This is a great activity. My son is interested in anatomy and have explained the heart and used the Usborne body book with flaps to explore how it is put together. At the vet the other day Goblin saw a model of a heart on a shelf and the vet let him take it apart and look. It was great. I’m pinning your post so can do this activity.

  9. Very nicely done. We did the same project but on a larger scale. Check out the Ameriheart.

  10. This is so neat! I think my son would get a kick out of it! Thanks for linking up at Tell Me About It Tuesday. We hope you hop over and share with us again next week.

  11. What a cool way to teach kids about the heart!

    Thanks for linking up at Tell Me About It Tuesday!

  12. What a nifty thing to do with my grandchildren! Thanks fr sharing.

  13. This is really fantastic!

    Thank you for stopping by the Thoughtful Spot Weekly Blog Hop this week. We hope to see you drop by our neck of the woods next week!

  14. This is a really a great project. I did notice that there is an error in this post that isn’t in the french (original post). *Then we saw that there are 3 ventricles in the heart* There are only 2 ventricles. You might want to edit that.

  15. Now, that’s a very creative activity! Impressive! I am honored that you shared at Home and Garden Thursday!

  16. Very cool learning the heart idea!
