Introduction

Duration: 15 to 20 minutes

Emotional Warm-up Activity

Conscious Breathing for Focus 🧘‍♂️

The emotional warm-up activity is a mindfulness practice aimed at promoting focus, presence, and concentration among students. During this activity, students will be guided through a series of conscious breathing and self-observation exercises, which will help bring mindful attention to the present moment. This exercise not only prepares the mind for learning but also allows students to recognize and regulate their emotions, facilitating a calmer and more productive environment for studying the respiratory system.

1. Environment Preparation: Ask students to sit comfortably in their chairs, with their feet flat on the floor and their hands resting on their knees. Make sure the room is quiet.

2. Introduction: Briefly explain to the students that they will practice a mindfulness technique called 'Conscious Breathing', which will help bring attention to the present moment.

3. Start of Breathing: Ask students to close their eyes, if they feel comfortable, and begin to pay attention to their breathing. Instruct them to breathe deeply through the nose, feeling the air enter and exit the lungs.

4. Breathing Count: Guide the students to mentally count each breath: inhale counting to 4, hold the air in the lungs counting to 4, exhale counting to 4, and then hold the lungs empty counting to 4 again.

5. Mindfulness: During the practice, remind students to bring their attention back to their breathing if they notice their mind starting to wander. Emphasize that it's okay to get distracted, but they should gently redirect their focus back to their breathing.

6. Conclusion: After about 5 minutes, ask students to slowly begin to move their fingers and toes, then slowly open their eyes. Ask how they felt and if they noticed any changes in their emotional state.

7. Reflection: Encourage students to reflect on how this conscious breathing practice can be useful in moments of stress or anxiety during studies or in other everyday situations.

Content Contextualization

The respiratory system is vital for our survival and well-being. It not only provides us with oxygen, essential for energy production in cells, but also plays a crucial role in regulating emotions. For example, deep breathing techniques are often used to calm the mind in moments of anxiety or stress. Understanding how our body performs this function can help us value the importance of taking care of our respiratory health even more. Additionally, by studying the respiratory system, we can better understand how our emotions are connected to our physiology, which is fundamental for developing self-awareness and self-control skills.

Development

Duration: 60 to 75 minutes

Theoretical Framework

Duration: 25 to 30 minutes

1. Organs of the Respiratory System: The respiratory system is composed of several organs that work together to facilitate breathing. These include:

2. Nose and Nasal Cavity: Responsible for the intake of air, they also warm, humidify, and filter the inhaled air.

3. Pharynx: Common channel for air and food, connecting the nasal cavity to the larynx.

4. Larynx: Also known as the voice box, it allows the passage of air between the pharynx and the trachea and is responsible for sound production.

5. Trachea: The tube connecting the larynx to the bronchi, allowing air to pass into the lungs.

6. Bronchi and Bronchioles: Branches of the trachea that lead air to the alveoli in the lungs.

7. Lungs: Main organs of respiration, where gas exchange occurs between oxygen and carbon dioxide.

8. Alveoli: Small air sacs in the lungs where gas exchange with the blood takes place.

9. Diaphragm: Muscle that separates the thoracic cavity from the abdominal cavity and plays a crucial role in breathing by contracting and relaxing.

10. Functioning of the Respiratory System: The respiratory system works through a cyclic process of inhalation and exhalation:

11. Inhalation: The diaphragm contracts and descends, increasing the volume of the thoracic cavity and allowing air to enter the lungs.

12. Gas Exchange: The inhaled oxygen passes from the alveoli into the blood, while carbon dioxide passes from the blood into the alveoli to be exhaled.

13. Exhalation: The diaphragm relaxes and rises, decreasing the volume of the thoracic cavity and expelling air from the lungs.

14. Example: When running, the respiratory rate increases to meet the greater demand for oxygen by the muscles and to expel the excess carbon dioxide produced.

15. Analogy: Think of the respiratory system as a building's ventilation system. The air (oxygen) is brought through ducts (airways), processed (gas exchange in the alveoli), and the used air (carbon dioxide) is expelled back into the environment.

Socioemotional Feedback Activity

Duration: 30 to 35 minutes

Exploring the Respiratory System with Models 🧪

Students will build models of the respiratory system using simple materials such as balloons, straws, and plastic bottles. This hands-on activity aims to consolidate theoretical knowledge through visualization and manipulation of the components of the respiratory system.

1. Group Division: Divide the class into groups of 3 to 4 students.

2. Material Distribution: Provide each group with balloons, straws, plastic bottles, tape, and scissors.

3. Model Construction: Instruct students to follow a step-by-step guide to build a model of the respiratory system. The balloon will represent the diaphragm, the straws will be the bronchi, and the bottle will represent the thoracic cavity.

4. Demonstration of Breathing: Ask students to manipulate the model, simulating the contraction and relaxation of the diaphragm (balloon) to observe how this affects the intake and expulsion of air in the lungs (bottle).

5. Group Discussion: After the construction, each group should discuss how the activity helped to understand the functioning of the respiratory system and the emotions they felt during the activity.

6. Presentation of Models: Each group will present their model to the class, explaining the parts and the breathing process.

Group Discussion

After the activity, guide a group discussion using the RULER method to provide socio-emotional feedback. Start by recognizing the emotions students felt during the model construction, asking if they felt frustration, excitement, or curiosity. Then, help them to understand the causes of those emotions, such as difficulties in construction or the satisfaction of seeing the model work. Name the emotions correctly, for example, saying 'it seems there was a bit of frustration with assembling the balloon, right?'. Encourage students to express these emotions appropriately, discussing how they dealt with challenges and how they felt about overcoming them. Finally, help them to regulate their emotions, suggesting strategies to maintain calmness and concentration in future activities. Ask how they can apply these learnings in other areas of life and studies. This approach promotes self-awareness, self-control, social skills, and social awareness, which are essential for socio-emotional development.

Conclusion

Duration: 15 to 20 minutes

Emotional Reflection and Regulation

To carry out the reflection and emotional regulation, suggest that students write a paragraph or participate in a group discussion about the challenges faced during the lesson and how they managed their emotions. During this activity, encourage them to think about specific moments when they experienced difficulties or frustrations and how they managed to overcome them. They can share strategies used to maintain calmness and concentration and discuss how these strategies can be applied in other challenging situations in the future.

Objective: The objective of this subsection is to encourage self-assessment and emotional regulation, helping students identify effective strategies for dealing with challenging situations. By reflecting on their experiences, students develop greater self-awareness and self-control, as well as social skills and social awareness, which are essential for socio-emotional development.

Closure and A Look Into The Future

To conclude the lesson, the teacher may suggest that each student set a personal goal and an academic goal related to the content learned about the respiratory system. These goals can be recorded in a journal or on a piece of paper to be shared with the class. Explain that the personal goal may relate to how they will better take care of their respiratory health in daily life, while the academic goal may be an objective for further study of the respiratory system or for applying knowledge in other subjects.

Possible Goal Ideas:

1. Personal Goal: Practice conscious breathing techniques daily to improve emotional and physical well-being.

2. Personal Goal: Avoid harmful habits to respiratory health, such as smoking.

3. Academic Goal: Study in more detail the diseases that affect the respiratory system and their prevention.

4. Academic Goal: Apply knowledge about the respiratory system in interdisciplinary projects, such as in physical education or chemistry. Objective: The objective of this subsection is to strengthen students' autonomy and the practical application of learning, aiming for continuity in academic and personal development. By setting clear and achievable goals, students can feel more motivated and engaged in the learning process, as well as develop planning and self-management skills.
