1. Identify and describe the main factors that affect the speed of a chemical reaction (temperature, concentration, pressure, and catalyst).

2. Develop the ability to recognize and understand the emotions involved in solving complex problems in chemistry, using the RULER method.

Introduction

Duration: 10 - 15 minutes

Emotional Warmup Activity

🌟 Inner Journey: Guided Meditation for Focus and Concentration 🌟

The chosen emotional warm-up activity is Guided Meditation. This exercise helps students enter a state of calmness and focus, readying their minds for learning. Guided meditation is useful for alleviating stress and anxiety, creating an emotionally balanced and focused atmosphere.

1. Setting the Environment: Ask students to sit comfortably in their chairs and gently close their eyes. Dim the lights in the room, if possible, and remove any distractions.

2. Initial Guidance: Let students know that guided meditation will help them ease into relaxation and concentration. Encourage them to be present and set aside any thoughts or concerns.

3. Deep Breathing: Guide students to take deep breaths, inhaling through their nose and exhaling through their mouth several times. Encourage them to feel the air filling their lungs, and then slowly releasing.

4. Visualization: Lead students in an imaginative exercise. For example, ask them to envision a serene and safe place, like a tranquil beach or a lush green field. Describe the surroundings (sounds, colors, sensations) to aid in their visualization.

5. Body Focus: Direct students to focus on different parts of their body, starting from their feet and moving upward to their head, relaxing each part as they proceed.

6. Gradual Return: After about 5-10 minutes, gently bring students back to the present moment. Ask them to start moving their fingers and toes, eventually opening their eyes slowly.

7. Quick Reflection: Give students a few moments to share how they felt during the meditation and discuss how it could help them concentrate better in class.

Content Contextualization

Chemical kinetics examines the rate of chemical reactions and the various factors that influence it, such as temperature, concentration, pressure, and catalysts. This branch of chemistry is vital for numerous practical applications, from the pharmaceutical industry to culinary practices. For instance, adjusting the temperature while cooking can either speed up or slow down the cooking process. Similarly, catalysts play a role in automotive systems to reduce pollutant emissions. By understanding how these factors impact reaction speeds, students can make informed and responsible choices in their daily lives and in prospective careers.

Development

Duration: 60 - 75 minutes

Theory Guide

Duration: 20 - 25 minutes

1. Chemical Kinetics: This is the field of chemistry that investigates the speed of chemical reactions and the factors influencing it. Understanding this topic is crucial for predicting reaction behavior and optimising industrial and laboratory processes.

2. Factors Affecting Reaction Speed:

3. Temperature: Raising the temperature typically accelerates chemical reactions as particles gain kinetic energy and collide more forcefully. Example: Cooking ingredients at higher temperatures reduces preparation time.

4. Concentration: Increasing the concentration of reactants speeds up reactions because more particles are available to collide. Example: A more concentrated acid solution reacts with metal much quicker.

5. Pressure: This mainly affects reactions involving gases. Elevating the pressure increases the concentration of gas molecules, enhancing the chances of productive collisions. Example: The Haber process for synthesizing ammonia is more effective under high pressure.

6. Catalyst: A substance that increases reaction speed without undergoing any change itself. It offers an alternative route with lower activation energy. Example: Automotive catalysts that accelerate the breakdown of hazardous gases.

7. Analogies to Facilitate Understanding: Compare the speed of a chemical reaction to a race. Temperature is akin to giving racers a head start to run quicker. Concentration is like boosting the number of racers on the track, resulting in more overtaking. Pressure is akin to narrowing the track, causing runners to collide more often. Catalyst is like a safer shortcut that helps racers reach the finish line faster without an increase in their running pace.

Activity with Socioemotional Feedback

Duration: 30 - 35 minutes

🧪 Hands-on Experiment: Investigating the Factors of Reaction Speed 🧪

Students will engage in a hands-on experiment to explore how various factors impact the speed of chemical reactions. They will collaborate in groups to observe and document changes in reaction speeds by manipulating temperature, concentration, and the presence of a catalyst.

1. Divide students into groups of 4-5.

2. Provide each group with the necessary materials: reactants, thermometers, stopwatches, test tubes, and catalysts.

3. Instruct each group to perform the following tasks:

4. Vary Temperature: Conduct the chemical reaction at different temperatures (e.g., room temperature, warm water, hot water) and record the time taken for the reactions.

5. Modify Concentration: Carry out the reaction with varying concentrations of reactants and note the reaction times.

6. Add Catalyst: Perform the reaction both with and without the catalyst and observe the differences in the reaction duration.

7. Encourage students to discuss their observations during the experiment within their groups and to take notes.

8. After completing the experiment, have students compare their results and evaluate how each factor influenced the reaction speed.

9. Prepare a table for students to log their observations and findings.

Discussion and Group Feedback

For the socioemotional discussion and feedback, employ the RULER method. First, recognize the emotions exhibited during the experiment: inquire how students felt while collaborating and observing results. Then, understand the causes and outcomes of these emotions by discussing the impact of teamwork and communication on the experiment's flow.

Label the emotions accurately, assisting students in identifying feelings such as frustration, excitement, or surprise. Express emotions constructively, fostering a respectful and open environment for students to share their experiences. Lastly, regulate emotions by discussing coping strategies for negative feelings while reinforcing positive emotions, thus creating a harmonious and effective learning environment.

Conclusion

Duration: 20 - 25 minutes

Reflection and Emotional Regulation

For the reflection and emotional regulation activity, it is recommended that the teacher facilitate a group discussion or invite students to write a paragraph about the challenges they encountered during the class and how they managed their emotions. Encourage students to reflect on specific instances when they felt frustrated, excited, or surprised and how these emotions influenced their learning and interactions with peers. Further, prompt students to consider strategies they utilized or could have employed to effectively regulate their emotions during the experiment.

Objective: The goal of this segment is to foster self-assessment and emotional regulation, equipping students with effective strategies to navigate challenging situations. Reflecting on their emotions and actions during the class will enhance self-awareness and enable them to manage their emotional responses more constructively in future scenarios.

Glimpse into the Future

To wrap up the lesson, the teacher can prompt students to set personal and academic objectives related to the topics covered. For instance, ask students to specify a goal, such as deepening their understanding of catalysts in chemical reactions or applying concepts of chemical kinetics in a practical project. Encourage them to contemplate concrete steps they can take towards achieving these goals and reflect on how sharpening their socioemotional skills can support their aspirations.

Penetapan Objective:

1. Review and deepen understanding of factors affecting the speed of chemical reactions.

2. Apply chemical kinetics concepts in hands-on experiments.

3. Cultivate teamwork and effective communication skills during lab activities.

4. Practice emotional regulation in challenging educational contexts.

5. Establish a study routine for reviewing concepts and practicing exercises related to chemical kinetics. Objective: The aim of this section is to reinforce students' autonomy and practical application of their learning, focusing on continuous academic and personal growth. Setting clear and attainable goals helps maintain focus and motivation while promoting the integration of socioemotional skills alongside academic content.
