In this blog post we write about making the heart working model science projects – simple and easy using cardboard and syringes
Creating a working model of the heart using cardboard, colored paper, and syringes is an educational way to understand the basic functioning of the human heart and its chambers.
Here’s how you can build this model:
Materials You’ll Need:
- Cardboard sheets (for the base and structure)
- Colored paper (for chambers and valves)
- Syringes (to represent heart chambers)
- Craft knife or scissors
- Hot glue gun and glue sticks
- Craft supplies for decoration (markers, stickers, etc.)

- Prepare the Base:
- Cut a large piece of cardboard as the base for your model.
- Construct the Heart Structure:
- Cut and assemble cardboard pieces to create a 3D representation of the heart.
- Designate areas for the atria and ventricles.
- Create Chambers with Syringes:
- Attach syringes to the heart structure to represent the chambers of the heart.
- Attach the plungers of the syringes to cardboard flaps or valves.
- Design Valves and Vessels:
- Cut colored paper to create flaps that represent the heart valves.
- Attach the valve flaps to the cardboard structure at appropriate locations.
- Model Interaction:
- Push and pull the plungers of the syringes to simulate the contraction and relaxation of the heart chambers.
- Observe how the valves open and close as the syringes move.
- Decoration:
- Decorate the model with colored paper, markers, or other craft supplies to make it visually appealing.
This model offers a simplified representation of the heart’s chambers and valves and demonstrates how blood flows through the heart during its contraction and relaxation. It’s a hands-on way to learn about the cardiovascular system and its essential role in pumping oxygenated blood throughout the body.
