Lesson Plan | Socioemotional Learning | Electricity: Electric Power

Objectives

Duration: (10 - 15 minutes)

The purpose of this stage of the Socio-emotional Lesson Plan is to introduce students to the topic of electricity, specifically electrical power, using an approach that promotes the development of socio-emotional skills. Through the understanding of concepts and the execution of calculations, students will be encouraged to recognize and regulate their emotions during the learning process, as well as to develop social skills and social awareness while working in groups and discussing the problems presented.

Main Goals

1. Understand the basic concepts of electric power and the Joule effect.

2. Calculate the power generated by the Joule effect in a resistor or electrical circuit.

3. Solve practical problems involving the calculation of electric power, such as the time required to heat a specific amount of water.

Introduction

Duration: (15 - 20 minutes)

Emotional Warm-up Activity

Mindfulness Breathing for Focus and Concentration

The emotional warm-up activity will be a Mindfulness session focused on breathing and relaxation. The goal is to promote students' focus, presence, and concentration, emotionally preparing them for the Physics class. This technique helps to reduce stress and anxiety, fostering a calmer mental state that is receptive to learning.

1. Ask students to sit comfortably in their chairs, with their feet flat on the ground and hands resting on their knees.

2. Request them to close their eyes or maintain a soft gaze, focused on a point ahead.

3. Guide them to pay attention to their breathing, noticing the air entering and leaving their nostrils.

4. Instruct them to count to four mentally while inhaling, and to count to four again while exhaling, maintaining a steady rhythm.

5. After a few breaths, ask them to expand the count to six, prolonging the inhalation and exhalation.

6. If thoughts or distractions arise, gently ask them to bring their attention back to the breath, without judgment.

7. Continue guiding them in this practice for about 5 to 7 minutes.

8. Wrap up by asking them to slowly open their eyes and become aware of their surroundings, ready to start the class.

Content Contextualization

Electricity is a fundamental part of our daily lives, present in almost every aspect of modern life. From charging our electronic devices to the operation of appliances and lighting systems, electricity is essential for our well-being and productivity. Understanding how to calculate electrical power allows us to assess the efficiency and energy consumption of devices, helping us make more responsible and conscious decisions about electricity usage.

By studying electrical power, students not only develop technical skills but also learn to handle practical challenges and work as a team to solve problems. This process promotes the development of socio-emotional competencies, such as responsible decision-making and collaboration, which are essential for personal and professional life.

Development

Duration: (60 - 75 minutes)

Theoretical Framework

Duration: (20 - 25 minutes)

1. Electrical Power: Electrical power is the measure of how quickly electrical energy is converted into another form of energy, such as heat, light, or motion. The unit of measurement is the watt (W).

2. Electrical Power Formula: The basic formula for calculating electrical power is P = V * I, where P is power, V is voltage in volts, and I is current in amperes.

3. Joule Effect: The Joule effect describes the conversion of electrical energy into heat in a conductor. The formula is P = I² * R, where R is resistance in ohms.

4. Example 1: If a 10-ohm resistor is traversed by a current of 2 amperes, what is the dissipated power? Using the formula P = I² * R, we have P = 2² * 10 = 4 * 10 = 40 watts.

5. Example 2: A device operates at a voltage of 220 volts and a current of 5 amperes. What is the power consumed? Using the formula P = V * I, we have P = 220 * 5 = 1100 watts.

6. Practical Application: Calculate the time needed to heat a specific amount of water. The formula for the required heat is Q = m * c * ΔT, where Q is the heat in joules, m is the mass of the water in kg, c is the specific heat of water (approximately 4.18 J/g°C), and ΔT is the temperature change. Knowing that P = Q/t, where t is the time in seconds, we can rearrange to find t = Q/P.

Socioemotional Feedback Activity

Duration: (30 - 35 minutes)

Calculating Electrical Power in Everyday Situations

Students will be divided into groups to solve practical problems involving the calculation of electrical power. Each group will receive a set of problems simulating real situations, such as calculating the power needed to heat an electric resistor or determining the energy consumption of a household device.

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

2. Distribute a sheet of practical problems to each group.

3. Ask the groups to work together to solve each problem, applying the formulas and concepts discussed in the theoretical section.

4. Encourage students to discuss the solutions and explain their reasoning to each other.

5. Request that a representative from each group presents the solutions found and the strategies used.

6. During the presentation, ask questions and provide feedback to ensure everyone understands the concepts.

Group Discussion

After the activity, lead a group discussion using the RULER method. Start by asking students to recognize the emotions they felt during the activity, such as frustration, excitement, or anxiety. Then, understand the causes of these emotions, relating them to the challenges or successes encountered during problem-solving.

Ask students to name these emotions and express them appropriately, sharing their experiences with the group. Finally, discuss ways to regulate these emotions in future activities, such as breathing techniques or more effective collaboration. This process will help students develop self-control and improve their social skills and responsible decision-making.

Conclusion

Duration: (15 - 20 minutes)

Emotional Reflection and Regulation

Suggest that students write a reflective paragraph about the challenges encountered during the lesson, both conceptual and emotional. Ask them to describe how they felt at different moments of the lesson, such as when solving a difficult problem or collaborating with peers. Then, lead an open discussion where students can share their reflections and strategies used to manage their emotions. Encourage them to talk about how they dealt with frustration, anxiety, or excitement, and which emotional regulation techniques were effective for them.

Objective: The objective of this activity is to encourage students to practice self-assessment and emotional regulation. By reflecting on their experiences and sharing with peers, they can identify effective strategies for coping with challenging situations. This helps in the development of self-awareness, self-control, and social skills, promoting a more collaborative and emotionally intelligent learning environment.

Closure and A Look Into The Future

Explain to students the importance of setting personal and academic goals to consolidate learning and apply the concepts of electrical power in practical situations. Ask each student to write a personal goal and an academic goal related to the lesson content. For example, a personal goal might be to save energy at home while an academic goal might be to solve additional electricity problems to reinforce understanding.

Possible Goal Ideas:

1. Personal: Reduce electricity consumption at home by turning off appliances that are not in use.

2. Personal: Apply emotional regulation techniques learned during the lesson in other challenging situations.

3. Academic: Solve three additional problems of electrical power to reinforce understanding of the concepts.

4. Academic: Help a peer who is struggling to understand the concepts of electrical power. Objective: The objective of this subsection is to strengthen students' autonomy and ensure the practical application of learning. By setting clear goals, students can monitor their progress and continue to develop both academic and socio-emotional skills. This promotes continuity in personal and academic development, encouraging responsibility and proactivity in learning.
