By understanding the objectives of the lesson, students can align their expectations and prepare emotionally for the content that will be addressed, facilitating a more effective and integrated learning process along with the development of socio-emotional skills.

Main Goals

1. Understand what Simple Harmonic Motion (SHM) is and its fundamental characteristics.

2. Calculate the amplitude, velocity, and acceleration at notable points of a mass-spring system.

3. Determine the period of the SHM of a mass-spring system.

Introduction

Duration: 10 - 15 minutes

Emotional Warm-up Activity

Deep Breathing for Focus and Concentration

The chosen emotional warm-up activity is 'Deep Breathing'. Deep Breathing is a technique that helps calm the mind and body, promoting focus, presence, and concentration among students. This activity involves controlled and conscious breathing, which can reduce anxiety and prepare students for more effective learning.

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

2. Instruct students to close their eyes or maintain a soft gaze at a fixed point in front of them.

3. Guide them to inhale deeply through the nose, counting to four slowly.

4. Ask them to hold their breath for a brief moment, counting to two.

5. Instruct them to exhale slowly through the mouth, counting to six.

6. Repeat this deep breathing cycle for about five times, encouraging students to focus on the sensation of air entering and leaving their lungs.

7. After the last exhale, ask students to slowly open their eyes and briefly reflect on how they feel calmer and more focused.

Content Contextualization

Simple Harmonic Motion (SHM) is a fundamental concept in physics that has numerous real-world applications, from engineering to music. For example, the functioning of musical instruments such as pianos and guitars relies on SHM to produce harmonious sounds. Additionally, many suspension systems in vehicles utilize principles of SHM to provide a smooth ride. By understanding how these concepts apply in our everyday lives, students can develop a sense of curiosity and appreciation for physics. Emotions such as curiosity and enthusiasm can be powerful allies in learning because they help maintain motivation and interest in the subject. Let's explore how physics and emotions are intertwined and how understanding SHM can help us see the world from a new perspective, both intellectually and emotionally.

Development

Duration: 60 - 75 minutes

Theoretical Framework

Duration: 25 - 30 minutes

1. Components of Simple Harmonic Motion (SHM):

2. Definition of SHM:

3. Explain that SHM is a type of oscillatory motion in which the restoring force is directly proportional to the displacement and acts in the opposite direction to the displacement.

4. Use the formula F = -kx, where F is the restoring force, k is the spring constant, and x is the displacement.

5. Amplitude (A):

6. Define amplitude as the maximum distance the mass moves from the equilibrium position.

7. Use visual examples, such as the oscillation of a pendulum or the vibration of a spring.

8. Period (T) and Frequency (f):

9. Define the period as the time required for one complete oscillation.

10. Introduce the formula T = 2π√(m/k), where m is the mass and k is the spring constant.

11. Explain the relationship between period and frequency: f = 1/T.

12. Velocity and Acceleration at Notable Points:

13. Discuss how velocity and acceleration vary throughout the motion.

14. Use the formulas v(t) = Aωcos(ωt + φ) and a(t) = -Aω²sin(ωt + φ), where ω = √(k/m) is the angular frequency.

15. Energy in SHM:

16. Explain the forms of energy involved (kinetic and elastic potential).

17. Use the elastic potential energy formula: U = 1/2 kx².

18. Relate to the conservation of energy in the system.

Socioemotional Feedback Activity

Duration: 35 - 40 minutes

Exploring SHM with a Virtual Simulation

Students will use an online simulation to explore Simple Harmonic Motion in a mass-spring system. The activity will involve manipulating the system parameters to observe how changes in mass and spring constant affect amplitude, period, velocity, and acceleration.

1. Access the virtual simulation of simple harmonic motion (provide the link to the simulation).

2. Divide students into groups of 3 to 4 people and ask them to discuss hypotheses about how changes in mass and spring constant will affect the system.

3. Instruct students to alter the values of mass and spring constant in the simulation and record observations about amplitude, period, velocity, and acceleration.

4. Ask students to note the results and compare them with the predictions made earlier.

5. Guide the groups to discuss how the observations align (or do not align) with the theories learned.

6. Request that each group presents their findings and discuss how they felt during the activity, focusing on any emotions of surprise, frustration, or satisfaction.

Group Discussion

To apply the RULER method, start by asking students to recognize (Recognize) and share the emotions they felt during the activity. Ask them how they felt when seeing their hypotheses confirmed or refuted by the simulation. Understand (Understand) the causes of these emotions by discussing what led to those feelings. For example, students may feel frustration if their predictions were wrong or satisfaction if they were correct. Ask students to label (Label) these emotions correctly, helping them identify if they were anxious, curious, frustrated, or excited. Encourage them to express (Express) these emotions appropriately, sharing their experiences with mutual respect. Finally, guide them to regulate (Regulate) their emotions by suggesting techniques such as deep breathing or reframing negative thoughts into positive ones, especially if they felt frustration or anxiety.

Conclusion

Duration: 15 - 20 minutes

Emotional Reflection and Regulation

After the practical activity, ask students to write a reflection or participate in a group discussion about the challenges faced during the lesson. Request them to describe how they managed their emotions throughout the activities, especially during moments of difficulty or surprise. Encourage them to think about how emotional regulation techniques, such as deep breathing or reframing thoughts, could have been or were utilized to deal with these challenges. This activity can be carried out in the form of a personal journal or in a talking circle, where each student shares their experiences and feelings.

Objective: The objective of this subsection is to encourage students to self-assess their emotional responses during the lesson and identify effective strategies for managing challenging situations. By doing this, students can develop a better understanding of themselves and improve their emotional regulation skills, applying them not only in an academic context but also in other areas of their lives.

Closure and A Look Into The Future

To conclude the lesson, propose that students set personal and academic goals related to the content learned. Explain that these goals may include improving calculations related to SHM, applying the concept to everyday problems, or practicing emotional regulation skills in other subjects. Encourage students to write down their goals and share them with a peer or with the class, fostering a supportive environment and shared responsibility.

Possible Goal Ideas:

1. Completely understand the concept of SHM and be able to explain it to a peer.

2. Improve accuracy in calculations of amplitude, velocity, and acceleration in mass-spring systems.

3. Apply SHM knowledge in practical situations, such as in engineering projects or music.

4. Practice emotional regulation techniques in academic and personal situations to enhance overall well-being.

5. Develop the ability to work effectively in groups, communicating ideas and emotions clearly and respectfully. Objective: The objective of this subsection is to strengthen students' autonomy by encouraging them to apply what they have learned in a practical and ongoing manner. By setting personal and academic goals, students become more aware of their own learning and development, promoting a sense of responsibility and motivation to continue advancing both academically and personally.
