Additionally, it aims to integrate the development of students' socio-emotional competencies, such as self-awareness and self-control, preparing them to deal with the emotions that arise during the learning process, promoting a more effective and harmonious learning environment.

Main Goals

1. Understand Stevin's theorem and its practical applications.

2. Calculate the pressure at specific points of a liquid using the formula P = P0 + dgh.

3. Develop socio-emotional skills such as self-awareness and self-control by understanding and managing emotions during the learning process.

Introduction

Duration: 10 - 15 minutes

Emotional Warm-up Activity

Guided Meditation for Focus and Presence

The chosen emotional warm-up activity is Guided Meditation. This practice involves leading students through a series of instructions designed to help them focus and concentrate on the present moment, promoting a state of calm and relaxation. Guided meditation is an effective technique for reducing stress and increasing attention, which is essential for effective learning.

1. Ask the students to sit comfortably in their chairs, with their feet on the floor and their hands resting on their laps.

2. Instruct them to close their eyes and begin to pay attention to their own breathing, inhaling and exhaling deeply.

3. Guide them to inhale through their nose counting to four, hold their breath for two seconds, and exhale through their mouth counting to six.

4. Suggest that during the exhalation, they try to relax their muscles even more and release any accumulated tension.

5. Lead them to imagine a tranquil and safe place, such as a beach or a field, and ask them to visualize this place with as much detail as possible.

6. Continue with this visualization for a few minutes, encouraging them to focus on the sensations of peace and tranquility that this place brings.

7. After about five minutes, ask them to begin to return their attention to the classroom, slowly moving their fingers and toes.

8. Finally, ask them to open their eyes slowly and, when they are ready, to do a light stretch before returning to a state of mindfulness.

Content Contextualization

To begin the class on Stevin's Theorem, it is important to relate the theory to practical applications and everyday situations. For example, Stevin's Theorem is fundamental for understanding how hydraulic systems work, such as car brakes or the hydraulic press in a workshop. These practical applications make the study of hydrostatics relevant and interesting for students, as they show how Physics is present in their daily lives.

Additionally, by exploring Stevin's Theorem, we can reflect on the importance of emotional balance when facing challenges and problems. Just as pressure distributes evenly in a liquid, our emotions also spread out and affect various areas of our lives. Learning to regulate these emotions, just as we understand pressure distribution, is essential for well-being and personal success.

Development

Duration: 60 - 70 minutes

Theoretical Framework

Duration: 25 - 30 minutes

1. Introduction to Stevin's Theorem

2. Stevin's Theorem is a fundamental law of hydrostatics that describes the variation of pressure in a fluid at rest. It states that the pressure difference between two points in a fluid is proportional to the height difference between those points and the density of the fluid.

3. Stevin's Theorem Formula

4. The mathematical formula of Stevin's Theorem is: P = P0 + dgh, where:

5. P is the pressure at a point in the fluid.

6. P0 is the pressure at the surface of the fluid.

7. d is the density of the fluid.

8. g is the acceleration due to gravity.

9. h is the height of the point considered relative to the surface.

10. Practical Example

11. Consider a water tank with a height of 10 meters. The atmospheric pressure at the surface is P0 = 101.325 Pa and the density of water is approximately 1000 kg/m³. What is the pressure at the bottom of the tank?

12. Using the formula: P = P0 + dgh, we have: P = 101.325 Pa + (1000 kg/m³)(9.8 m/s²)(10 m) = 101.325 Pa + 98,000 Pa = 199,325 Pa.

13. Analogies to Facilitate Understanding

14. A useful analogy is to imagine that the pressure in a fluid is similar to the weight we feel when diving into a swimming pool. The deeper we go, the greater the water pressure on our body, similar to the increased pressure at deeper points in a fluid.

15. Applications of Stevin's Theorem

16. Hydraulic Systems: The theorem is fundamental for understanding the functioning of hydraulic systems, such as car brakes and hydraulic presses.

17. Manometers: Use the principle of Stevin to measure the pressure in closed containers.

18. Beer and Soft Drink Kegs: The pressure inside the kegs is calculated using this theorem to ensure product quality.

Socioemotional Feedback Activity

Duration: 35 - 40 minutes

Liquid Pressure Experiment

Students will conduct a practical experiment to measure the pressure at different points in a liquid. They will use a transparent tube filled with water and manometers to record pressure readings at different heights. This activity will help visualize and verify Stevin's Theorem in practice.

1. Divide the students into groups of 4 to 5 people.

2. Distribute the necessary materials: transparent tubes, manometers, water, markers, and rulers.

3. Ask the students to mark different heights on the tube (for example, 2 cm, 4 cm, 6 cm, etc.).

4. Fill the tube with water up to the highest mark.

5. Instruct the students to connect the manometers at different heights and record the pressure readings.

6. Ask them to compare the readings and verify the relationship between height and measured pressure.

7. Ask each group to prepare a small report with observations and conclusions about the experiment.

Group Discussion

After the activity, lead a group discussion using the RULER method. Start by asking the students how they felt during the experiment (Recognize). Ask what challenges they faced and how they dealt with any frustrations or difficulties (Understand). Encourage them to correctly name their emotions, such as anxiety, curiosity, or satisfaction (Label). Discuss how to express these emotions appropriately, either through communication with peers or in written reflection (Express). Finally, explore strategies to regulate emotions, such as breathing techniques or reflection pauses, that could be used in future practical activities (Regulate).

This discussion not only reinforces technical learning but also promotes essential socio-emotional skills for the personal and academic development of students.

Conclusion

Duration: 10 - 15 minutes

Emotional Reflection and Regulation

Propose a final reflection with the students, which can be done in written form or as a group discussion. Ask the students what their biggest challenges were during the lesson and how they felt when dealing with those challenges. Encourage them to think about the strategies they used to manage their emotions, such as deep breathing, communication with peers, or reflection pauses. Ask them to share their experiences and discuss which techniques were most effective and why.

Objective: The objective of this reflection is to encourage students to self-assess their emotional responses during the lesson, helping them identify effective strategies for coping with challenging situations. This promotes self-awareness and self-control, essential skills for socio-emotional development, as well as preparing students to better manage their emotions in future academic and personal activities.

Closure and A Look Into The Future

To conclude the lesson, ask students to set personal and academic goals related to the content learned. Explain that these goals may include applying Stevin's Theorem to everyday problems, seeking more information about hydraulic systems, or developing specific pressure calculation skills. Encourage them to write these goals down and reflect on the steps they can take to achieve them.

Possible Goal Ideas:

1. Apply Stevin's Theorem to practical everyday problems.

2. Research more about hydraulic systems and their applications.

3. Practice pressure calculations using the formula P = P0 + dgh.

4. Develop a better understanding of the causes and consequences of emotions during challenging activities.

5. Improve emotional regulation techniques in academic situations. Objective: The objective of this subsection is to strengthen students' autonomy and the practical application of learning, encouraging them to set clear and achievable goals that will promote the continuity of their academic and personal development. By setting goals, students can focus on how to apply what they have learned in future contexts, as well as continue to develop their socio-emotional skills.
