Objective Sampingan:

1. Connect theoretical knowledge to practical, everyday instances.
2. Cultivate skills for analyzing and reflecting on biological processes.

Introduction

Duration: 10 - 15 minutes

The goal of this stage is to ignite students’ interest by making the topic relatable and relevant, while linking theoretical concepts to practical applications in the workplace. This engagement will set the stage for a more profound and impactful learning experience regarding metabolism.

Curiosities and Market Connection

 Curiosity: Did you know basal metabolism is the least amount of energy needed to keep your body’s vital functions running when you're at rest? That’s why our bodies continue to burn energy even while we sleep.  Market Connection: Knowledge of metabolism is applicable across various sectors like biotechnology for designing medications that alter metabolic rates, nutrition for creating targeted diets, and in the sports industry to enhance athletes' performance.

Contextualization

Metabolism comprises a series of chemical reactions that are essential for life, enabling the transformation of nutrients into energy and new cellular materials. Think of your body as a factory that requires fuel and raw inputs to function. These metabolic processes are crucial for growth, reproduction, and cellular upkeep. In biology, grasping the concept of metabolism is vital for understanding how living organisms exist, develop, and interact with their surroundings.

Initial Activity

️ Initial Activity: Present a short video (3-5 minutes) that outlines how metabolism impacts everyday life, including examples such as food digestion and energy usage during workouts. Then pose this thought-provoking question: "How might metabolism influence your daily life and future career paths?" Prompt students to share their immediate impressions.

Development

Duration: 70 - 75 minutes

This stage aims to foster a thorough and practical understanding of metabolism concepts, enabling students to utilize theoretical knowledge in experimental and reflective tasks. This reinforces their learning while developing analytical and practical abilities that hold value in the job market.

Topics

1. What metabolism means.

2. Differences between catabolic and anabolic metabolism.

3. Aerobic vs. anaerobic metabolism.

4. Chemical reactions involved and how they relate to energy flow.

Thoughts on the Subject

Encourage students to ponder how different metabolic types can affect health and wellness. Ask them to consider practical examples, like how diet and exercise can adjust the body's metabolism and impact their everyday lives and career aspirations.

Mini Challenge

Hands-on Experiment: Measuring Metabolic Rate

Students will experiment with determining the basal metabolic rate (BMR) of various simulated individuals using CO2 and O2 sensors to track cellular respiration under varying conditions.

1. Form groups of 4-5 students.

2. Supply the necessary materials: CO2 and O2 sensors, stopwatches, recording sheets, and calculators.

3. Each group will observe the CO2 output and O2 intake of a 'subject' at rest and following mild exercise.

4. Students should document their findings at 5-minute intervals over 20 minutes.

5. After collecting data, each team needs to calculate the BMR of their 'subject' and compare results across different scenarios.

6. Encourage groups to discuss and present their findings on how physical activity affects metabolic rate.

Comprehend the link between physical activity and metabolic rate, as well as enhance skills in data collection and analysis.

**Duration: 40 - 45 minutes

Evaluation Exercises

1. Clarify the difference between catabolic and anabolic metabolism with practical examples.

2. Contrast aerobic metabolism with anaerobic metabolism and cite examples of activities that use each process.

3. Illustrate why oxygen consumption is a marker of metabolic rate and its connection to energy production in the body.

Conclusion

Duration: (10 - 15 minutes)

This stage intends to consolidate students’ learnings, prompting them to reflect on the practical relevance of the concepts explored, while fostering a well-rounded understanding of metabolism's significance in daily life and future career decisions.

Discussion

 Discussion: Lead a conversation with students regarding their learnings and how the practical exercises enhanced their grasp of theoretical concepts. Encourage them to think about the mini challenges they faced and how measuring basal metabolic rate (BMR) clarified the connection between physical activity and metabolism. Pose the question: "In what ways do you think metabolism affects your health and career choices?".

Summary

 Summary: Reiterate the primary topics covered in the lesson, such as the definition of metabolism, and differences between catabolic vs. anabolic metabolism, and aerobic vs. anaerobic metabolism. Emphasize the significance of the underlying chemical reactions and the production/usage of energy.

Closing

 Closing: Discuss how the lesson integrated theory with practice through hands-on activities and reflective discussions, showcasing how knowledge of metabolism is relevant across multiple professional domains such as healthcare, biotechnology, and athletics. Stress the role of metabolism in sustaining life and overall health, and how comprehension of these processes can steer lifestyle decisions and career paths.
