Lesson Plan | Socioemotional Learning | Organic Functions: Amine Nomenclature

Objectives

Duration: 10 - 15 minutes

The purpose of this stage is to introduce the lesson's theme and the specific skills that students should develop. It establishes the foundation for learning, preparing students to understand the importance of the content and how it relates to their ability to identify and name organic compounds, specifically amines, using IUPAC nomenclature.

Main Goals

1. Name and recognize the appropriate IUPAC nomenclature for amines.

2. Differentiate the nomenclature of amines from that of other organic compounds.

Introduction

Duration: 20 - 25 minutes

Emotional Warm-up Activity

Guided Meditation for Focus and Concentration

The guided meditation activity is a technique that helps students achieve a state of calm and concentration, promoting focus and presence in the moment. This technique is especially useful for preparing students for learning, as it reduces anxiety and increases attention and retention of information.

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

2. Request that they close their eyes or maintain a soft gaze at a fixed point ahead.

3. Instruct students to breathe deeply through their noses, filling their lungs and then slowly releasing the air through their mouths. Repeat this breathing cycle three times.

4. Begin to guide students to focus on their breathing, feeling the air entering and exiting their bodies.

5. After a few moments, guide them into a visualization, asking them to imagine a calm and safe place where they feel relaxed and at peace.

6. Allow students to remain in this visualization state for a few minutes, encouraging them to explore the details of the imagined environment.

7. Gradually ask them to return their attention to the classroom, feeling their feet on the ground and their hands on their thighs.

8. Finally, request that they slowly open their eyes, bringing with them the feeling of calm and focus for the rest of the lesson.

Content Contextualization

The nomenclature of amines may seem like a purely technical topic, but understanding it is crucial for various practical applications that impact our daily lives. For example, amines are found in many medications we use to treat illnesses, as well as in cleaning products and even in foods. Understanding how to name and identify these compounds can help us make more informed and safe choices in our everyday lives.

Moreover, the ability to identify and label emotions correctly is as important as naming chemical compounds. Just as we need to follow specific rules for IUPAC nomenclature, we also need to understand and use appropriate emotional vocabulary to express our feelings clearly and appropriately. This lesson will not only teach the nomenclature of amines but also reinforce the importance of precise communication, both in the field of chemistry and in the emotional realm.

Development

Duration: 60 - 75 minutes

Theoretical Framework

Duration: 30 - 35 minutes

**1. 1. Definition and Structure of Amines: Amines are organic compounds derived from ammonia (NH₃) where one or more hydrogens are replaced by alkyl or aryl groups. Amines can be classified as primary (R-NH₂), secondary (R-NH-R'), and tertiary (R-NR'R').

2. IUPAC Nomenclature of Amines: To name a primary amine, the main chain is identified, and the suffix 'amine' is added to the name of the corresponding alkane. Example: methanamine (CH₃NH₂). For secondary and tertiary amines, the prefix 'N-' is used to indicate the groups attached to the nitrogen. Example: N-methylethanamine (CH₃NH-CH₂CH₃). In complex amines, the longest chain attached to the nitrogen is chosen as the main chain, and the other chains are named as substituents.

3. Physical and Chemical Properties: Amines have characteristic, often unpleasant smells. They can form hydrogen bonds, resulting in higher boiling points compared to hydrocarbons of similar molecular mass. They are weak bases and can react with acids to form ammonium salts.

4. Examples of Nomenclature: Methanamine (CH₃NH₂) N-methylethanamine (CH₃NH-CH₂CH₃) N,N-dimethylpropanamine (CH₃NH(CH₃)-CH₂CH₃)

5. Comparison with Other Organic Compounds: Differentiate amines from alcohols, ethers, and amides, highlighting the presence of nitrogen as the distinctive functional group of amines. Comparative example: Methanol (CH₃OH) vs. Methanamine (CH₃NH₂).**

Socioemotional Feedback Activity

Duration: 30 - 35 minutes

Identification and Nomenclature of Amines

In this activity, students will work in small groups to identify and name different amines based on their chemical structures. This activity aims to reinforce the theory learned and promote collaboration and socio-emotional skills.

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

2. Distribute to each group a set of cards with the chemical structures of different amines.

3. Ask the students to identify whether the amine is primary, secondary, or tertiary.

4. Instruct the groups to name each amine using the appropriate IUPAC nomenclature.

5. After identification and nomenclature, each group should present their answers to the class.

Group Discussion

After the activity is completed, organize a group discussion using the RULER method to provide socio-emotional feedback. First, recognize the emotions involved in the activity by asking students how they felt while working in groups and identifying the amines. Then, understand the causes of these emotions by discussing what may have led to feelings of frustration or satisfaction during the task.

Name the emotions correctly, helping students express clearly how they felt, for example, 'I felt anxious when I couldn't identify the amine correctly'. Express the emotions appropriately, encouraging an environment of mutual respect and support. Finally, help them regulate their emotions by discussing strategies to cope with frustration or anxiety in future activities, such as asking a classmate or teacher for help.

Conclusion

Duration: 10 - 15 minutes

Emotional Reflection and Regulation

Suggest that students write a brief paragraph or participate in a group discussion about the challenges they faced in naming and identifying amines. Ask them to reflect on how they felt while completing the activities, how they dealt with those emotions, and what they could do differently in future situations. Encourage them to share their emotional regulation strategies and how these strategies helped improve performance in class.

Objective: The objective of this subsection is to encourage students to practice self-assessment and emotional regulation, helping them identify and reflect on effective strategies for dealing with challenging situations. This promotes the development of greater emotional awareness and provides tools for them to better manage their emotions in future learning contexts.

Closure and A Look Into The Future

Explain to students the importance of setting personal and academic goals related to the content studied. Ask them to write a specific goal to improve their skills in the nomenclature of organic compounds and another for developing socio-emotional skills, such as collaboration in groups or emotional regulation. Encourage students to share their goals with the class, fostering a supportive environment.

Possible Goal Ideas:

1. Improve accuracy in the nomenclature of amines using IUPAC nomenclature.

2. Develop group work and collaboration skills.

3. Practice emotional regulation techniques to cope with academic frustrations.

4. Increase the ability to identify and express emotions appropriately. Objective: The objective of this subsection is to strengthen students' autonomy and encourage the practical application of learning, both in academic and personal contexts. Setting clear goals helps students focus on specific areas for improvement, promoting continuity in development and growth, as well as fostering resilience and proactivity in facing future challenges.
