Introduction

Duration: (15 - 20 minutes)

Emotional Warm-up Activity

Guided Meditation for Concentration

The suggested emotional warm-up activity is Guided Meditation. Guided Meditation is a practice that involves leading students through a series of verbal instructions to help them achieve a state of relaxation and concentration. This practice is effective in promoting focus, presence, and concentration, preparing students emotionally for the physics lesson on electricity. Guided meditation can reduce anxiety and stress, increasing students' ability to absorb and process new information.

1. Ask students to sit comfortably in their chairs, keeping their backs straight and their feet on the floor.

2. Instruct students to close their eyes and take deep breaths several times, inhaling through their nose and exhaling through their mouth.

3. Begin the guided meditation session with a calm, soft voice, asking students to pay attention to their breath, feeling the air entering and leaving their body.

4. Guide them to relax each part of their body, starting from their feet and moving up to their head, asking them to release any tension they may be holding.

5. Suggest they imagine a calm and safe place where they feel relaxed and at peace. It could be a beach, a forest, or any other place that brings them tranquility.

6. After a few minutes of visualization, ask students to slowly bring their attention back to the classroom while maintaining a sense of calm and focus.

7. Conclude the meditation by asking students to slowly open their eyes and take a few deep breaths before resuming the lesson.

Content Contextualization

Electricity is present in almost every aspect of our lives, from the operation of our electronic devices to the lighting in our homes. Understanding how electricity works, especially the work of electric force in uniform fields, allows us to better understand the world around us and develop more efficient technologies. Additionally, electricity serves as an excellent example of how invisible forces can have a significant impact on our lives, much like emotions. Recognizing and understanding electricity can help students see the importance of acknowledging and understanding their own emotions and those of others.

For example, when studying how electric force can move charged particles, students can draw an analogy to how emotions can influence our actions and decisions. Just as it is important to correctly calculate force and work in an electric field to avoid mistakes in practical applications, it is crucial to recognize and regulate our emotions to make responsible decisions and maintain healthy relationships.

Development

Duration: (60 - 75 minutes)

Theoretical Framework

Duration: (20 - 25 minutes)

1. Concept of Uniform Electric Field: Explain that a uniform electric field is one where the field strength is constant at any point. Highlight that it is represented by parallel and equidistant field lines.

2. Electric Force in Uniform Field: Detail that the electric force F acting on a charge q in a uniform electric field E is given by F = qE. Use practical examples, such as the force experienced by an electric charge between two parallel charged plates.

3. Work Done by Electric Force: Show that the work W done by an electric force moving a charge q in a uniform electric field is calculated by W = qEd, where d is the distance traveled in the direction of the field. Use analogies with mechanical work to facilitate understanding.

4. Electric Potential Energy: Explain that the electric potential energy of a charge q in an electric field E is given by U = qEd. Relate it to other types of potential energy that students may already know, such as gravitational potential energy.

5. Speed in Electric Fields: Detail how the speed of a charged particle can be determined at different points in the electric field, using the conservation of energy. Emphasize the formula (1/2)mv^2 = qEd to calculate the speed v of a particle of mass m.

6. Examples and Applications: Use practical examples, such as the movement of electrons in cathode ray tubes or the acceleration of particles in particle accelerators, to illustrate the concepts.

Socioemotional Feedback Activity

Duration: (30 - 35 minutes)

Calculating Work and Speed of Particles in Electric Fields

In this activity, students will solve problems involving the calculation of work done by electric forces in uniform fields and determine the speed of particles at different points in the field. The activity is designed to consolidate theoretical concepts and promote socio-emotional development by working in groups and reflecting on their emotions during problem-solving.

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

2. Distribute a worksheet with problems involving the calculation of work and speed in uniform electric fields.

3. Instruct students to discuss problem-solving strategies within their groups, encouraging collaboration and active listening.

4. Ask a representative from each group to share their solutions with the class, explaining the reasoning behind their answers.

5. As students work, circulate around the room to offer support, clarify doubts, and observe group dynamics.

6. At the end, facilitate a discussion on how group work helped solve the problems and how emotions influenced the problem-solving process.

Group Discussion

After the activity, use the RULER method to guide a group discussion focused on socio-emotional feedback. Recognize the emotions that emerged during the activity by asking students how they felt while solving problems in groups. Encourage them to understand the causes of those emotions, exploring how collaboration and communication influenced their feelings.

Ask students to name the emotions they experienced, such as frustration, joy, or anxiety. Discuss appropriate ways to express these emotions during group activities, emphasizing the importance of clear communication and mutual respect. Finally, help students to regulate their emotions by offering strategies to maintain calm and focus in challenging situations, such as pauses for deep breathing and the practice of empathy.

Conclusion

Duration: (15 - 20 minutes)

Emotional Reflection and Regulation

To reflect on the challenges faced in the lesson and how students managed their emotions, suggest that students write a short paragraph or participate in a group discussion. They should reflect on the emotions they felt while solving physics problems, such as frustration, anxiety, joy, or satisfaction, and the strategies they used to cope with these emotions. Students can share their experiences and discuss what worked well and what could be improved next time.

Objective: The objective of this subsection is to encourage students to self-evaluate their emotions and the effectiveness of the strategies they used to manage them. By identifying and reflecting on their emotions, students can develop better emotional regulation skills and adopt more effective approaches to facing future challenges. This practice of self-assessment promotes self-awareness and self-control, which are essential elements of socio-emotional development.

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 involve improving their understanding of electricity concepts, applying knowledge in future projects, or developing group work skills. Encourage students to write these goals in their notebooks and think of concrete steps they can take to achieve them.

Possible Goal Ideas:

1. Fully understand the concept of a uniform electric field.

2. Improve the ability to calculate the work done by electric forces.

3. Develop the ability to work effectively in groups.

4. Apply the concept of electric potential energy to practical problems.

5. Strengthen emotional regulation skills during challenging activities. Objective: The objective of this subsection is to strengthen students' autonomy and the practical application of learning. By setting personal and academic goals, students can focus on their continuous development, both academically and socio-emotionally. This practice helps students visualize their progress and commit to ongoing improvement in their skills and knowledge.
