Tujuan

Durasi: (10 - 15 minutes)

The purpose of this stage of the Socioemotional Lesson Plan is to establish a solid understanding of metallic bonds, allowing students to develop a clear conceptual grasp. This initial phase also sparks curiosity and prepares students for hands-on activities that integrate cognitive and socioemotional skills, such as self-awareness and social abilities, to better understand the topic.

Tujuan Utama

1. Understand the structure of metallic bonding through the concept of 'sea of electrons'.

2. Identify and explain the properties of metallic compounds, such as electrical and thermal conductivity, based on their electronic structure.

Kegiatan Pemanasan Emosional

Deep Breathing for Focus and Presence

Deep Breathing Mindfulness

1. Have students sit comfortably in their chairs, feet flat on the floor and hands relaxed on their thighs.

2. Guide them to gently close their eyes, focusing on their breath as they feel the air entering and leaving their bodies.

3. Begin a deep breathing exercise: inhale slowly through the nose for a count of four, hold for a count of four, and exhale gently through the mouth for a count of four.

4. Repeat this deep breathing cycle for five minutes, encouraging students to concentrate on the rhythm of their breath and the flow of air in and out of their bodies.

5. After the five minutes are up, invite students to slowly open their eyes and take a moment to reflect on how they feel more centered and engaged.

Kontekstualisasi Konten

Metallic bonding is a core concept in chemistry, explaining why metals excel at conducting electricity and heat. Consider how the electrical wires we encounter every day are crafted from metal. The efficiency of these cables in conducting electricity is tied to their metallic structure and the 'sea of electrons'. When we learn how electrons move freely within metals, we can better understand the practical uses of these materials in everyday items, from kitchen tools to electronic gadgets and even in construction.

Moreover, grasping metallic bonding allows us to appreciate the connection between science and our emotions. Just like electrons flow freely in metals, our emotions also move within us, shaping our actions and decisions. By learning about metallic bonding, we can draw connections to the significance of recognizing and managing our emotions, creating a more mindful and balanced classroom atmosphere.

1. ### Structure of Metallic Bonding

2. Definition: Metallic bonding is a chemical bond that occurs between metal atoms, characterized by a lattice of positive metal ions surrounded by a 'sea of free electrons'.

3. Example: In metals like copper and aluminum, the valence electrons move freely between atoms, creating a strong and cohesive bond.

4. Analogies: Think of metallic bonding like a pool filled with marbles (representing metal ions) where water (representing electrons) flows freely around them, allowing the marbles to stay together without touching directly.

5. ### Properties of Metals

6. Electrical Conductivity: Free electrons can easily move through the metal, enabling electrical current to flow.

7. Thermal Conductivity: The free movement of electrons also aids in transferring thermal energy, making metals excellent conductors of heat.

8. Malleability and Ductility: The presence of the 'sea of electrons' allows metal ions to slip over one another without compromising the structure, making metals malleable (able to be shaped) and ductile (able to be stretched into wires).

9. ### Practical Examples

10. Electrical cables are made of copper or aluminum because of their superb electrical conductivity.

11. Cooking pots are often made with metals like stainless steel or aluminum, which conduct heat efficiently.

12. ### Causes and Consequences of Metallic Properties

13. Cause: The unrestricted movement of electrons within the metallic structure.

14. Consequences: High electrical and thermal conductivity, as well as malleability and ductility.

Kegiatan dengan Umpan Balik Sosioemosional

Durasi: (30 - 35 minutes)

Exploring Metallic Properties

Students will participate in a hands-on activity to investigate the properties of metals, including electrical and thermal conductivity, through safe and straightforward experiments.

1. Divide the class into small groups (3-4 students).

2. Provide the necessary materials for the activity: copper wires, batteries, small light bulbs, thermometers, tongs, and both metallic and non-metallic objects.

3. Instruct students to set up a basic circuit using copper wires, batteries, and light bulbs, and observe electrical conduction.

4. Guide students to gently heat metallic objects using a safe heat source (like a lamp) and measure the temperature at various points to observe thermal conduction.

5. Ask groups to document their findings and discuss how the results relate to the 'sea of electrons' concept and metallic properties.

Diskusi dan Umpan Balik Kelompok

After completing the hands-on activity, lead a group discussion using the RULER method to explore students' emotions and experiences during the activity.

Recognize: Prompt students to share how they felt while conducting the experiments and watching the results unfold. Encourage them to identify their emotions, whether they were feeling curious, frustrated, or satisfied.

Understand: Discuss what caused those emotions. For instance, curiosity may have come from the novelty of the situation, while frustration might have stemmed from practical challenges.

Name: Help students accurately label their emotions. Use terms like 'enthusiasm', 'confusion', 'joy', and 'frustration'.

Express: Encourage students to share their emotions constructively, explaining how they felt and the reasons behind it.

Regulate: Talk about strategies for managing emotions, such as practicing deep breathing when feeling frustrated, or celebrating small successes when they achieve a clear understanding or a positive result in the activity.

Kesimpulan

Durasi: (10 - 15 minutes)

Refleksi dan Regulasi Emosional

To reflect on the challenges faced during the lesson and how students managed their emotions, ask them to write a paragraph about their experiences. Alternatively, facilitate a group discussion where students can share their experiences orally. Encourage them to touch on moments of difficulty, the emotions they felt, and the strategies they employed to navigate these challenges.

Tujuan: The goal of this section is to foster self-assessment and emotional regulation, helping students to identify effective strategies for coping with challenging scenarios. This promotes a conscious awareness of their emotions, aiding in the development of skills to manage emotional responses in both academic and personal contexts.

Pandangan ke Masa Depan

To establish personal and academic goals connected to the lesson content, ask students to draft a list of three objectives they aim to achieve. These goals can be short-term—like reviewing the material on metallic bonds—or long-term, such as applying the knowledge they've gained in future projects or subjects.

Penetapan Tujuan:

1. Review the material on metallic bonds.

2. Apply insights on electrical and thermal conductivity in a science project.

3. Create a presentation about the properties of metals to share with the class. Tujuan: The aim of this section is to bolster students' independence and the practical application of their learning. Setting personal and academic goals encourages students to stay focused on their ongoing growth and skill development, promoting a sense of responsibility and strategic planning in their educational journeys.
