If your children or students have come to school for the lesson related to breathing, this craft that we propose can become a very useful educational resource. Is about a homemade mockup (or DIY Do It Yourself, as they say lately) that helps children to understand the respiratory system in a more fun way.
It is a very simple educational children's craft in which you can involve your children in its preparation. Thanks to her, your children will learn what organs and parts of the body the respiratory system is made of and how it works. It will also allow them to experience breathing and its sensations in their own body. And once again, with activities like this we encourage recycling. How about? It is a very complete project for school that your children will love to create, so do not hesitate to write down the material you will need and follow this easy step by step to make your own model of the respiratory system at home!
- A 0.5l transparent plastic bottle
- 2 orange straws
- 2 pink balloons
- 1 green balloon
- Permanent red marker
- Scotch tape
- Glue stick
- Cutter and scissors
- Flesh-colored eva rubber
Today, we study the science of the human body! Before making this model, it is good to refresh some concepts related to its operation. You can talk about all this to your children or students while you create this model. In this way, you will be reinforcing the knowledge and you will be able to create even more expectation when doing it. Let's see!
As you well know, the respiratory system is made up of the nose, throat, larynx, trachea, and lungs.
- The nose and mouth
The nostrils take in the air from outside, but the air can also be inhaled through the mouth. These two airway openings meet at the pharynx or throat.
- The pharynx
The pharynx is also part of the digestive system as it is responsible for transporting air and food. They may have been very attentive in class and already know it, but you sure capture their attention and curiosity.
- The larynx
The larynx, also called the voice box, is at the top of the airway. It is called a voice box, because inside it contains a pair of vocal cords that produce noise when vibrating.
- The trachea, bronchi and lungs
On the other hand, the trachea extends downward, from the base of the larynx, and is responsible for eliminating harmful particles that penetrate from the outside through the respiratory tract, preventing them from entering the lungs.
At the lower end, the trachea divides into two tubes, one going to the right and the other going to the left. These tubes are called bronchi, and they are connected to the lungs, located inside our rib cage or thorax.
- The diaphragm
The diaphragm separates the chest from the abdomen. When inhaling it moves downwards, allowing us to increase the capacity of the thoracic cavity, and when we exhale it moves upwards. As the cavity moves upwards, it decreases, thus allowing the gases from the lungs to rise and be expelled from our body through the nose or mouth, since the air that we breathe and that moves inside us is not only composed Of oxygen, it also contains carbon dioxide, which is a waste gas that is generated during energy-producing processes in the body.
1. To represent this part of the body, we are going to use the plastic bottle. Start by cutting the base of the bottle with the help of a cutter. It does not matter if it is perfect because later you can go over the edges with the scissors.
2. Discard the base of the bottle and drills a hole in the plug. You can do it with the help of scissors if they are pointed scissors, otherwise you can use the tip of a knife. As you can see, these first steps require the presence of an adult, to avoid accidents.
3. Now it is time to make the lungs, represented by the two pink balloons. To do this, you have to cut the nozzle with the scissors and use the permanent red marker to paint the bronchi. We are having a good time!
4. The two orange straws, will represent the larynx and trachea. You can use straws of other colors if you do not have this tone. You have to place them on the table but face down, that is, the part through which we absorb will be the lower part of the trachea that is divided into two tubes, so you can connect your balloon-lungs next.
5. Put one of the balloon lungs in a straw, and tape it around the straw. Repeat the process with the other straw and the other balloon lung, and tape the straws together, about 5 cm above the balloon lungs.
6. Insert the straws with the balloon-lungs inside the bottle. You must be careful and do it at the bottom of the bottle, leaving them approximately in the center of it. Next, insert the nozzle (the part that is free) of the straws through the hole you have made in the cap and close the bottle. We are about to finish!
7. Cut the green balloon to remove the nozzle and place it covering the base of the bottle. This balloon represents the diaphragm, which plays a very important role in breathing. We have chosen the color green because it is the color that represents the energy point that is located in this area of our body, but you can choose another color.
8. To reinforce the memorization of the names of the different parts, you can do a list of the organs and parts of the body that are part of the respiratory system and / or involved in breathing: Nose, mouth, throat, larynx, trachea, bronchi, bronchioles, alveoli, lungs and diaphragm. You can also make a drawing of a nose and a mouth to make the model more visual.
Cut out the pictures and the list, and glue them onto flesh-colored rubber foam.
9. There is only glue the nose and mouth at the top of the bottle, and the list on the side, so it will serve as a guide.
We have already finished! Now is the time to play and experiment!
What activities can we learn from this DIY model? What knowledge can we bring to children. Let's see it one by one.
How does the respiratory system work?
The first and most obvious use that you can make of this model is to learn how the respiratory system works. You can name each of the organs and understand what their function is.
To give life to this model, your children will only have to blow and absorb some air through the straws, so they can observe the movement of the globe-lungs and globe-diaphragm. They will be able to observe how the air passes from the nose, the trachea and reaches the lungs, as it happens in our body.
They will also experience what happens to them in their own body when they blow faster or slower. By blowing fast, your breathing quickens and your body sensations change; They will make a 'drowning' face. When they blow slower, that feeling of suffocation disappears. In this way they will better understand how the human body works.
Activity to restore calm of children
The respiratory system is in charge of the functioning of our breathing, a function so important that our body performs it on its own and automatically, but it is very beneficial become aware of our breathing, since learning to observe and regulate it can help us improve our mood, increase and dose our energy throughout the day and control periods of nervousness, stress or anxiety.
This is why our Respiratory System Bottle can be used to calm a child who is nervous. To do this, we have to ask you to blow through the straw for as long as you can. By concentrating on your relaxation, you will forget what is making you nervous and tend to relax.

A fabulous breathing exercise
You can complete this learning with a breathing exercise that will not only help them understand the reason for these sensations, but also will balance your breathing and ensuring complete expulsion of carbon dioxide.
These types of exercises are done and learned in yoga, so you can practice it together! We explain how to do it:
Begins spontaneously breathingYou just have to observe and feel how the air enters and leaves through the nose, and if the inhalation lasts the same as the exhalation. For this you can perform counts from 1 to 3 or from 1 to 5, depending on your breathing. You already have it? Do this 2 or 3 times in a row, and then try taking a little deeper breaths, equalizing the time during inhalation and exhalation.
For example, you inhale in 4 and exhale in 4. Both you and your child will begin to feel more relaxed.
Feel your abdomen inflate. Then feel the air open the base of the lungs, reaching up to the chest and raising the sternum. After several breaths, you can feel the air in your clavicles. Feel the air rise through the throat and nose, reaching the inside of the head, in the central part of the forehead, slightly above the eyes.
After several breaths that have allowed you to feel all these parts of the body, take a deep breath, counting for example from 1 to 4, trying to slow down the air output when counting from 1 to 8.
You can imagine that by taking off the air, you are not only expelling carbon dioxide, but you are also expelling negative emotions or feelings that you have not expressed in order to let go and let them go. As you take in air, imagine that you are not only taking in oxygen, but breathing positive energy.
The more you practice, the better it will turn out and the better you will feel! If at any point you notice your heart rate racing or your eyes start to twitch, stop exercising and breathe spontaneously, then start over, don't get frustrated.
It is a good exercise to end the day and relax before falling asleep, and it is also good in the morning, when you wake up, just before you get out of bed. This helps us become aware of ourselves.
We encourage you to experiment!
