Introduction

Duration: (15 - 20 minutes)

Emotional Warmup Activity

Guided Meditation for Focus and Presence

The warm-up activity chosen is Guided Meditation. This practice guides students through a set of verbal instructions designed to help them relax, focus, and be mindful. It can enhance concentration, ease anxiety, and prepare their minds for learning.

1. Preparing the Environment: Instruct students to sit comfortably in their chairs, with their feet flat on the ground and hands resting on their knees. Make sure the environment is as quiet as possible.

2. Initial Breathing: Ask students to close their eyes and take deep breaths, inhaling through the nose and exhaling through the mouth. They should repeat this breathing cycle three times.

3. Guiding Attention: Start the guided meditation by asking students to focus on their bodies. Encourage them to feel their weight in the chairs and the sensation of their feet on the ground.

4. Visualization: Invite students to picture a calm, safe place, like a serene beach or a lush green field. Describe this place in detail, highlighting the sounds, smells, and sensations.

5. Breath Focus: After a few minutes of visualization, redirect their focus back to their breath. Instruct them to notice the air flowing in and out of their bodies without trying to control it.

6. Closure: Gently ask students to move their fingers and toes, open their eyes, and stretch a bit. Conclude by thanking everyone for participating and reinforcing the importance of being present and focused for the lesson ahead.

Content Contextualization

Alcohols are organic compounds that play a significant role in our daily lives. Whether it's ethanol, which is in alcoholic beverages, or isopropyl alcohol, frequently used for cleaning, these compounds have numerous practical applications. For instance, during the COVID-19 pandemic, the importance of hand sanitizers for hygiene was emphasized, showcasing the relevance of these compounds in society.

Moreover, understanding the characteristics and properties of alcohols empowers students to make informed and responsible choices in their everyday dealings, whether that involves using cleaning products safely or moderating alcohol consumption. This knowledge encourages empathy and social awareness, highlighting how chemistry contributes to health and well-being in our community.

Development

Duration: (60 - 75 minutes)

Theory Guide

Duration: (20 - 25 minutes)

1. Definition of Alcohol: An alcohol is an organic compound that features one or more hydroxyl groups (-OH) attached to saturated carbon atoms. The general formula is R-OH, with R representing an alkyl group.

2. Classification of Alcohols: Alcohols can be classified based on how many hydroxyl groups they possess: Monohydric Alcohols: Have one hydroxyl group (e.g., ethanol). Dihydric Alcohols: Contain two hydroxyl groups (e.g., ethylene glycol). Trihydric Alcohols: Have three hydroxyl groups (e.g., glycerol).

3. Physical Properties: Melting and Boiling Points: Alcohols generally feature higher melting and boiling points than hydrocarbons with similar molecular weights due to hydrogen bonding. Solubility: Short-chain alcohols are soluble in water, while longer-chain alcohols are less soluble.

4. Chemical Properties: Reactivity: Alcohols can undergo oxidation, producing aldehydes, ketones, or carboxylic acids. Moreover, they can react with acids to leave behind esters. Reaction with Sodium: Reacting with sodium produces hydrogen gas.

5. Examples and Applications: Ethanol: Commonly found in alcoholic beverages and used as a solvent. Methanol: Used as an industrial solvent and fuel. Isopropanol: Serves as an antiseptic and solvent.

Activity with Socioemotional Feedback

Duration: (30 - 40 minutes)

Interactive Experiments with Alcohols

Students will carry out a series of mini-experiments to observe the physical and chemical properties of alcohols, followed by a group discussion applying the RULER method to explore emotional and social responses during these activities.

1. Group Division: Split the students into groups of 4-5.

2. Experiment 1 - Solubility: Provide samples of different alcohols (ethanol, methanol, isopropanol) along with water. Students should mix each sample with water and observe the solubility.

3. Experiment 2 - Boiling Point: Use laboratory heaters to heat samples of ethanol and gauge the temperature at which they start to boil.

4. Experiment 3 - Reaction with Sodium: Carefully introduce small pieces of sodium to ethanol samples and observe the reaction (ensure strict supervision and safety measures).

5. Record Observations: Each group must document their observations in a lab notebook.

6. Group Discussion: After completing the experiments, students should discuss their observations while addressing the following guided questions using the RULER method.

Discussion and Group Feedback

To steer the group discussion and put the RULER method into practice, begin by encouraging students to recognize their feelings and describe any emotions they felt during the experiments. Ask if any moments elicited curiosity, anxiety, or surprise for them. Next, assist them in understanding the reasons behind these emotions, discussing how the novelty of the experiments and teamwork might affect their emotional responses.

Move onto labeling emotions by asking students to identify their feelings accurately, like excitement, nervousness, or satisfaction. Encourage them to express their emotions properly by sharing their experiences and insights within the group. Finally, discuss ways to regulate these emotions, suggesting self-management techniques such as deep breathing or taking pauses to maintain emotional control during future activities.

Conclusion

Duration: (15 - 20 minutes)

Reflection and Emotional Regulation

Encourage students to write a brief reflection or engage in a group discussion about the challenges they faced throughout the lesson, particularly during the experiments with alcohols. Ask them to reflect on how they managed feelings such as curiosity, anxiety, or surprise, and the impact of these emotions on their learning and teamwork. Their reflections should include strategies they employed to maintain emotional control, as well as improvements they could consider for future activities.

Objective: The purpose of this section is to prompt students to engage in self-assessment and learn to regulate their emotions consciously. By recognizing the emotions experienced and the strategies utilized to tackle challenges, students can enhance their emotional intelligence and apply these skills across various contexts, fostering a constructive and balanced learning atmosphere.

Glimpse into the Future

To wrap up the lesson, prompt students to set both personal and academic goals related to their insights on alcohols. This can be achieved through a brief writing exercise where each student outlines one or two goals they wish to pursue, such as improving their understanding of chemical reactions involving alcohols or incorporating this knowledge into a science project. Encourage them to detail specific steps to achieve these goals and share their intentions with the class.

Penetapan Objective:

1. Deepen their understanding of chemical reactions involving alcohols.

2. Apply knowledge of alcohols to a science project.

3. Practice reading and analyzing scientific articles about alcohols.

4. Enhance laboratory skills through more chemical experiments.

5. Increase awareness of the significance of alcohols in everyday life and various industries. Objective: The aim of this section is to bolster students' independence and practical application of what they have learned. By establishing personal and academic goals, students are motivated to pursue their educational and personal growth while acknowledging the significance of the material they’ve learned and its broader applications. This fosters a sense of purpose and direction in their ongoing learning journey.
