Introduction

Duration: 10 - 15 minutes

Emotional Warmup Activity

Deep Breathing for Focus and Concentration

For our emotional warm-up, we’ll do 'Deep Breathing'. It's a technique that calms the mind and body, helping students to focus and concentrate better. This exercise involves deep, controlled breathing, which can alleviate anxiety and create a readiness for learning.

1. Instruct students to sit comfortably, with feet flat on the floor and hands resting on knees.

2. Encourage them to close their eyes or softly gaze at a fixed point ahead.

3. Guide them to take a deep breath in through their nose, counting slowly to four.

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

5. Instruct them to breathe out slowly through their mouth, counting to six.

6. Repeat this cycle about five times, encouraging students to feel the air entering and leaving their lungs.

7. After the last exhale, prompt students to gently open their eyes and reflect on how they feel, noting a sense of calm and focus.

Content Contextualization

Simple Harmonic Motion (SHM) is a fundamental physics concept with varied real-world applications, from engineering to music. For instance, instruments like pianos and guitars depend on SHM to produce harmonious sounds. Similarly, vehicle suspension systems apply SHM principles to ensure a smooth ride. By recognizing the relevance of such concepts in daily life, students cultivate curiosity and appreciation for physics. Emotions like curiosity and enthusiasm are pivotal in retaining students' motivation and engagement. Let’s delve into how physics interconnects with emotions and how comprehending SHM can enrich our worldview, both intellectually and emotionally.

Development

Duration: 60 - 75 minutes

Theory Guide

Duration: 25 - 30 minutes

1. Components of Simple Harmonic Motion (SHM):

2. Definition of SHM:

3. Define SHM as a type of oscillatory motion where the restoring force is proportional to the displacement, acting in the opposite direction.

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

5. Amplitude (A):

6. Define amplitude as the farthest distance the mass travels from its equilibrium position.

7. Use relatable examples, like the swing of a pendulum or the vibration of a spring.

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

9. Define the period as the time taken for a full oscillation.

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

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

12. Velocity and Acceleration at Notable Points:

13. Discuss how velocity and acceleration change during 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 formula for elastic potential energy: U = 1/2 kx².

18. Relate this to conservation of energy within the system.

Activity with Socioemotional Feedback

Duration: 35 - 40 minutes

Exploring SHM through a Virtual Simulation

Students will access an online simulation to investigate Simple Harmonic Motion in a mass-spring system. They will alter the system's parameters to observe how changes in mass and spring constant influence amplitude, period, velocity, and acceleration.

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

2. Break students into groups of 3 to 4 and ask them to discuss how changes in mass and spring constant may affect the system.

3. Instruct students to modify mass and spring constant values in the simulation and note their observations on amplitude, period, velocity, and acceleration.

4. Have students compare their results with their earlier predictions.

5. Guide the groups to discuss how their observations matched (or didn’t match) the theories covered.

6. Encourage each group to present their findings and reflect on their emotional experiences during the activity, focusing on feelings of surprise, frustration, or delight.

Discussion and Group Feedback

Applying the RULER method, start by asking students to recognize (Recognize) and share the emotions they experienced during the activity. Discuss their feelings when their hypotheses were confirmed or disproven by the simulation. Understand (Understand) what caused these emotions and why they felt that way—frustration if things didn't work out, satisfaction if they did. Help students accurately label (Label) those emotions as anxious, curious, frustrated, or excited. Encourage them to express (Express) those emotions appropriately, sharing experiences with mutual respect. Finally, guide them to regulate (Regulate) their emotions, suggesting techniques like deep breathing or reframing negative thoughts positively, particularly in times of frustration or anxiety.

Conclusion

Duration: 15 - 20 minutes

Reflection and Emotional Regulation

Post-activity, prompt students to engage in written reflections or participate in group discussions about challenges faced during the lesson. Encourage them to articulate how they managed their emotions throughout, particularly in challenging or surprising situations. Motivate them to consider emotional regulation techniques, like deep breathing or adjusting thoughts, as strategies they could use or employed to face those challenges. This reflection may take the form of a personal journal entry or a sharing circle, where each student discusses their experiences and feelings.

Objective: The aim of this section is to encourage students to self-evaluate their emotional responses during the lesson and recognize effective strategies to handle challenges. This assessment helps them develop self-awareness and improve their emotional regulation skills, applying these insights beyond academic contexts into their lives.

Glimpse into the Future

To wrap up the lesson, encourage students to set personal and academic goals in relation to the topics covered. These goals may include enhancing their skills in SHM calculations, applying the concepts to real-life problems, or implementing emotional regulation skills in other subjects. Have students jot down these goals and share them with a peer or the class to foster a supportive atmosphere and accountability.

Penetapan Objective:

1. Achieve a comprehensive understanding of SHM and explain it effectively to a peer.

2. Enhance accuracy in calculating amplitude, velocity, and acceleration in mass-spring systems.

3. Apply SHM knowledge to practical scenarios, such as in engineering tasks or music.

4. Practice emotional regulation techniques in academic and personal settings to improve overall well-being.

5. Develop the ability to work collaboratively in groups, effectively communicating ideas and feelings with respect. Objective: The objective of this segment is to empower students to apply their learnings in practical and ongoing ways. By setting personal and academic goals, students can become more conscious of their learning journey and development, instilling a sense of accountability and motivation to progress academically and personally.
