In this post we write making of LUNGS MODEL (human respiratory system) making for school science exhibition | diy
Creating a lungs model using plastic paper, woolen thread, and cardboard can be a great way to understand the basic structure and function of the lungs.
Let’s build a simple 3D model that demonstrates the lungs’ anatomy and the process of breathing.
Materials needed:
- Cardboard (for the base and structures)
- Plastic wrap or plastic sheet (for representing the lung sacs)
- Woolen thread (for representing the trachea and bronchi)
- Scissors
- Glue or double-sided tape
- Marker pens or sketch pens
Step-by-step instructions:
- Base:
- Cut a rectangular or square piece of cardboard to serve as the base for the model.
- Lungs:
- Use plastic wrap or plastic sheet to represent the lung sacs.
- Cut out two large oval or balloon-shaped pieces from the plastic wrap. These will be the lung sacs.
- Trachea and Bronchi:
- Use woolen thread to represent the trachea and bronchi.
- Attach one end of the woolen thread at the top of one lung sac to represent the trachea.
- Divide the thread into two parts and attach each part to the bottom of each lung sac to represent the bronchi.
- Alveoli:
- Use smaller pieces of plastic wrap to create tiny air sacs called alveoli.
- Cut out many small, irregular shapes from the plastic wrap and glue them inside the lung sacs to represent the alveoli.
- Diaphragm:
- Use cardboard to create the diaphragm, the muscle that helps in breathing.
- Cut out a curved shape from the cardboard and glue it at the bottom of the lung sacs to represent the diaphragm.
- Labeling and Details:
- Use marker pens or sketch pens to label the different parts of the model, such as the trachea, bronchi, alveoli, and diaphragm.
- Decorating the Model:
- Use markers or color paper to decorate the model and add more details to make it visually appealing.
Now, you have a simple 3D lungs model made from plastic paper, woolen thread, and cardboard. This model can be a helpful visual aid to understand the basic structure and function of the lungs, including how air flows through the trachea and bronchi into the alveoli during breathing.
It’s an interactive and creative way to explore the respiratory system and learn about the vital role of the lungs in the process of breathing.
