In this blog post we have written enough details on how to make the respiratory system lung model for science exhibition project using cardboard waste materials at home easily
Creating a respiratory system model using cardboard and color paper is a great way to understand and visualize how the respiratory system works. This interactive model will allow you to open different parts to see the details inside the respiratory organs.
Here’s a step-by-step guide to making this model:
Materials Needed:
- Cardboard: For the base and structure.
- Color Paper: For decorating and detailing the organs.
- Glue: For assembling the model.
- Scissors and Craft Knife: For cutting the cardboard and paper.
- Markers, Paint, or Colored Pencils: For labeling and adding details.
- Ruler: For measuring and drawing.
- Brads (paper fasteners): For creating movable parts.
- String or Thin Thread: To represent the trachea and bronchi.

1. Prepare the Base:
- Cut a large rectangular piece of cardboard to serve as the base for your model.
- Optionally, cover the base with color paper or paint it for a more polished look.
2. Create the Outline of the Respiratory System:
- Draw a basic outline of the respiratory system on the cardboard base. Include the nasal cavity, trachea, bronchi, lungs, and diaphragm.
3. Create the Nasal Cavity and Mouth:
- Cut out shapes for the nasal cavity and mouth from cardboard.
- Cover these shapes with color paper. Use red or pink for the mouth and nasal cavity.
- Attach these shapes to the top of your base.
4. Create the Trachea:
- Use a piece of string or thin thread to represent the trachea.
- Glue the string from the bottom of the nasal cavity down to where the bronchi will branch off.
- Alternatively, you can cut a narrow strip of cardboard, cover it with color paper, and use it as the trachea.
5. Create the Bronchi and Bronchioles:
- Use string or thin thread to represent the bronchi branching off from the trachea into the lungs.
- For the bronchioles, you can use smaller pieces of string branching off from the bronchi.
6. Create the Lungs:
- Cut out two lung shapes from cardboard. Make them slightly larger than needed, as you will cut them open later to show the interior details.
- Cover the lungs with color paper. Use light pink or a similar color.
- Attach the lungs to the base on either side of the bronchi.
7. Create the Diaphragm:
- Cut out a curved shape from cardboard to represent the diaphragm.
- Cover it with color paper and attach it to the bottom of the lungs.
8. Create Flaps to Show Inside Details:
- Cut openable flaps on the lung shapes to show inside details such as the alveoli.
- Cut smaller lung shapes from cardboard to fit inside the flaps. These will represent the internal view of the lungs.
- Cover these smaller lung shapes with color paper and draw details like alveoli using markers or paint.
- Attach these smaller lung shapes inside the flaps using glue.
9. Add Details and Labels:
- Use markers or paint to add details such as blood vessels around the alveoli.
- Label all parts of the respiratory system clearly with markers or printed labels.
10. Assemble and Add Final Touches:
- Ensure all parts are securely attached and that the flaps open and close easily.
- Add any additional details or decorations to make your model more informative and attractive.
Conclusion:
This model of the respiratory system is a great educational tool to visualize how the respiratory organs work and their internal structures. It’s perfect for a school project or a science fair, allowing for an interactive way to learn and teach the respiratory system. Enjoy building and presenting your model!
