The purpose of this stage is to provide students with a clear and detailed understanding of the objectives of the lesson, aligning them with the socio-emotional skills to be developed. This creates a solid foundation for learning, allowing students to know exactly what is expected of them and how the lesson will contribute to their academic and emotional development.

Main Goals

1. Recognize the structure of the current periodic table, identifying metals, nonmetals, and specific families.

2. Develop the ability to locate and identify elements in the periodic table.

3. Understand the importance of the organization of the periodic table for chemistry and society.

Introduction

Duration: (20 - 25 minutes)

Emotional Warm-up Activity

Journey Through the Mind

The chosen emotional warm-up activity is Creative Visualization. This technique involves creating vivid and detailed mental images to induce a state of relaxation and focus. The practice not only helps calm the mind but also improves concentration and presence in the moment.

1. Preparation of the Environment: Ask students to find a comfortable position and close their eyes. Make sure the room is quiet and dimly lit.

2. Initial Breathing: Ask them to take three deep breaths, inhaling through the nose and exhaling through the mouth, focusing all attention on their breathing.

3. Beginning the Visualization: Instruct students to imagine a calm and beautiful place, such as a deserted beach, a serene forest, or a flower-filled field. Detail that they should envision themselves walking in this place, feeling the ground beneath their feet, hearing the sounds around them, and noticing the scent in the air.

4. Sensory Exploration: Guide students to explore this environment with all their senses. Ask them to touch the leaves of the trees or the sand, hear the sound of birds or ocean waves, and feel the breeze on their face.

5. Focus on Relaxation: Encourage students to enjoy this experience, allowing any tension in their bodies to dissolve as they deepen into the visualization.

6. Gradual Return: After a few minutes, ask students to start bringing their attention back to the present by slowly moving their fingers and toes, and opening their eyes when they feel ready.

7. Sharing Experiences: Reserve a moment for students to share how they felt during the visualization and if they noticed any changes in their emotional state.

Content Contextualization

The Periodic Table is not only an essential tool for chemistry but also a fascinating representation of the order and beauty of the universe. It helps us understand how the elements that make up everything around us are organized in a logical and systematic manner. Imagine the Periodic Table as a large map that guides scientists in their research and discoveries. Just as good organization can bring clarity and tranquility into our lives, the structure of the Periodic Table facilitates the understanding of the elements and their interactions. This teaches us to value order and organization, skills that are important both in study and in life.

Development

Duration: (60 - 75 minutes)

Theoretical Framework

Duration: (25 - 30 minutes)

1. Introduction to the Current Periodic Table: Explain that the periodic table is a tabular arrangement of chemical elements, organized based on their chemical and physical properties. Mention that the modern table was developed by Dmitri Mendeleev and has been refined over time.

2. Structure of the Periodic Table: Detail that the table is composed of horizontal rows called periods and vertical columns called groups or families. Each element is represented by a square that includes its chemical symbol, atomic number, and atomic mass.

3. Classification of Elements: Describe how the elements are classified in the table: metals, nonmetals, and metalloids. Explain that metals are generally located on the left and in the center, nonmetals on the right, and metalloids form a dividing line between metals and nonmetals.

4. Families of the Periodic Table: Explain the main families of elements, such as alkali metals (Group 1), alkaline earth metals (Group 2), halogens (Group 17), and noble gases (Group 18). Give examples of elements belonging to each family.

5. Periodic Properties: Discuss some important periodic properties such as electronegativity, atomic radius, and ionization energy. Explain how these properties vary across the periods and groups of the table.

6. Applications and Importance: Mention some practical applications of the elements and the importance of the periodic table in chemistry and everyday life. For example, how metals are used in construction and electronics manufacturing, or how noble gases are used in lighting and technology.

Socioemotional Feedback Activity

Duration: (30 - 35 minutes)

Getting to Know the Periodic Table

In this activity, students will explore the periodic table in an interactive game format. They will work in groups to find and identify specific elements, classify them as metals, nonmetals, or metalloids, and associate them with their respective families.

1. Group Formation: Divide the class into small groups of 4 to 5 students.

2. Task Distribution: Give each group a copy of the periodic table and a set of cards with the names of chemical elements.

3. Instructions for the Game: Explain that each group must find the elements in the periodic table, classify them as metals, nonmetals, or metalloids, and identify which family they belong to.

4. Recording Responses: Ask each group to record their answers on a piece of paper, including the symbol of the element, its classification, and its family.

5. Time for Completion: Give the groups 20 minutes to complete the activity.

6. Presentation of Results: After the allotted time, ask each group to present their answers to the class, explaining their choices and classifications.

Group Discussion

After the presentation of results, use the RULER method to guide a group discussion. Recognize the emotions demonstrated by students during the activity, such as enthusiasm or frustration, and understand the causes of these emotions. Label the emotions correctly, for example, 'I see that some of you are excited about discovering the elements.' Express empathy and support, encouraging open and respectful communication among students. Regulate the emotions by offering positive and constructive feedback, helping students deal with feelings of frustration or insecurity, and reinforcing the importance of teamwork and cooperation.

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 a writing or group discussion activity. Ask students to write a paragraph about a specific challenge they faced during the periodic table activity and how they felt dealing with it. Alternatively, lead a group discussion where students can share their experiences and emotions, discussing the strategies they used to manage these feelings.

Objective: The objective of this subsection is to encourage self-assessment and emotional regulation, helping students identify effective strategies for dealing with challenging situations. This reflection will allow students to recognize their feelings, understand their reactions, and develop greater emotional resilience applied to the context of the lesson on the periodic table.

Closure and A Look Into The Future

To conclude the lesson, suggest that students set personal and academic goals related to the content learned. Explain that each student should choose a personal goal, such as improving their ability to work in teams, and an academic goal, such as memorizing the main groups of the periodic table. Encourage them to write down these goals and think about concrete steps they can take to achieve them.

Possible Goal Ideas:

1. Memorize the main groups of the periodic table.

2. Improve ability to work in teams.

3. Enhance the skill to identify chemical elements.

4. Develop effective study strategies for chemistry.

5. Increase confidence in presenting group results. Objective: The objective of this subsection is to strengthen students' autonomy and the practical application of learning, aiming for continuity in academic and personal development. Setting goals helps students focus on their continuous growth and apply the socio-emotional skills developed during the lesson in their daily lives and future academic activities.
