Objectives (5 - 7 minutes)

1. Understanding Ecosystem Services: Students will be able to define and explain the concept of ecosystem services, recognizing how they are essential to human life and the economy.
2. Identifying Types of Ecosystem Services: Students will learn to identify and categorize the various types of ecosystem services - such as provisioning, regulating, cultural, and supporting services - and understand how they function.
3. Appreciating the Importance of Ecosystem Services: Students will develop an appreciation for the value of ecosystem services in their daily lives and the impacts of human activities on these services.

Secondary Objectives:

• Promote Critical Thinking: Through the lesson, students will be encouraged to think critically about the relationship between humans and the environment.
• Enhance Collaboration: The hands-on activities included in the lesson will foster teamwork and collaboration among students.
• Encourage Environmental Consciousness: By the end of the lesson, students should feel a sense of responsibility towards the environment and its preservation.

Introduction (10 - 15 minutes)

1. Recalling Previous Knowledge: The teacher begins the lesson by reminding students of the basic concepts of ecosystems and their components. They might ask questions like, "What are some examples of ecosystems you've learned about?" or "Can you remember the different components of an ecosystem?" This is crucial to ensure that students have the necessary foundation for understanding the concept of ecosystem services.

2. Problem Situations: The teacher then presents two problem situations that will serve as the starting point for the lesson.

   • The first situation could be about a city that has been heavily polluted, leading to the destruction of its local ecosystem. The teacher could ask, "What might be some of the consequences for the city and its residents?" This would lead to a discussion about the loss of ecosystem services such as clean air and water, and the impacts on human health and well-being.
   • The second situation could involve a farmer who has cut down a large area of forest to expand his crop fields. The teacher could ask, "What might happen to the soil, water, and climate in this area?" This would prompt a discussion about the role of forests in providing ecosystem services like soil conservation, water regulation, and climate control.

3. Real-world Contextualization: The teacher then contextualizes the importance of the subject by explaining how ecosystem services are not just abstract concepts, but vital for our daily lives. They could cite examples such as how we rely on bees for pollination (a type of ecosystem service) for a significant portion of our food supply, or how wetlands provide flood control and water purification services, saving millions of dollars in infrastructure costs.

4. Introduction of the Topic: The teacher introduces the topic of the day - Ecosystem Services. They explain that these are the benefits that people obtain from ecosystems, emphasizing that they are not just nice to have, but necessary for our survival and well-being. The teacher could say, "Think of ecosystem services as the 'free gifts' that nature provides us with - clean air, fresh water, fertile soil, pollination, climate regulation, and even cultural and recreational benefits."

5. Engaging the Students: To capture the students' attention and curiosity about the topic, the teacher might share some interesting facts or stories related to ecosystem services.

   • They could share the story of the 'Day the Sea Caught Fire' - the 1969 fire on the Cuyahoga River in Cleveland, Ohio, caused by severe pollution, which led to the creation of the Environmental Protection Agency (EPA) in the US and the Clean Water Act. This story highlights the importance of water and its role as an ecosystem service.
   • Another interesting fact could be about the economic value of ecosystem services. The teacher could share that a study by the World Bank estimated the value of global ecosystem services at $33 trillion - more than double the global GDP at the time. This fact could spark a discussion about the economic benefits of conserving ecosystems.

Development (20 - 25 minutes)

Activity 1: Ecosystem Services Market Game

1. Preparation: The teacher will prepare for the activity by setting up a large, open space in the classroom or outdoor area. They will also need to create cards representing different ecosystem services (clean air, fresh water, fertile soil, pollination, climate regulation, cultural and recreational benefits) and cards representing different human activities that impact these services (deforestation, air and water pollution, urbanization, etc.). Each card should have a brief description of the service or activity it represents.

2. Group Formation: The class is divided into small groups of 4 to 5 students. The teacher will assign each group a specific ecosystem they'll represent during the activity (forest, wetland, farmland, etc.).

3. Activity Set-up: The teacher will place the ecosystem and human activities cards on the floor, scattered over the designated area. The ecosystem cards will be placed at one end, and the human activities cards at the other end.

4. Instructions: The teacher will explain the rules of the game. Each team's objective is to transport as many ecosystem service cards as possible from their ecosystem to the market (human activities area) without crossing over any human activities cards. If they accidentally step on a human activity card, they must return to their ecosystem with all the cards they were carrying. The first team to successfully deliver all their ecosystem service cards to the market wins the game.

5. Gameplay: The students will take turns, with one member from each group starting at their ecosystem and attempting to reach the market. The other team members will act as 'environmental defenders,' warning their teammate if they are getting close to stepping on a human activity card.

6. Discussion: Debrief the activity by discussing the strategies used by the teams to avoid human activities and deliver the ecosystem services. Relate this discussion to real-world scenarios, emphasizing the importance of protecting ecosystems from harmful human activities to preserve ecosystem services.

Activity 2: Ecosystem Services Role Play

1. Preparation: The teacher will prepare by creating role play scenarios related to different ecosystem services. For example, a scenario could involve a farmer (provisioning service) deciding whether to use pesticides or more sustainable farming methods. Another scenario could involve a city planner (regulating service) deciding whether to build on a floodplain or preserve it as a wetland.

2. Group Formation: Students remain in their small groups from the previous activity.

3. Instructions: The teacher will explain the activity. Each group will receive a role play scenario card. They have 5 minutes to discuss and prepare a short role play (1-2 minutes) that demonstrates the importance of their assigned ecosystem service and the potential impacts of human activities on it.

4. Role Play Performance: Groups take turns performing their role plays.

5. Discussion: The teacher guides a discussion after each role play, focusing on what ecosystem service was depicted, how it was affected by human activities, and the potential consequences of these impacts. This will help students understand the real-world implications of their actions on ecosystem services.

6. Reflection: After all the role plays have been performed, the students will have a moment to reflect on both activities. The teacher will pose reflection questions such as "What did you learn about the importance of ecosystem services from these activities?" and "How can you apply this knowledge in your everyday life?" This reflection will help students internalize the lesson and its implications.

Feedback (8 - 10 minutes)

1. Group Discussion: The teacher will facilitate a group discussion where each group will have up to 3 minutes to share their solutions or conclusions from the activities. This will allow students to learn from each other's perspectives and experiences, enhancing their understanding of the topic. The teacher will guide the discussion by linking the students' findings back to the theoretical concepts of ecosystem services.

2. Connecting Theory and Practice: The teacher will then summarize the key points from the group discussions, highlighting how the activities demonstrated the real-world application of the theory of ecosystem services. They will emphasize that the decisions we make as individuals and as a society can have significant impacts on the provision of ecosystem services and, consequently, our own well-being. The teacher could say, "Remember, every choice we make, from the food we eat to the way we travel, can either support or harm ecosystem services."

3. Reflection: The teacher will propose that students take a moment to reflect on what they have learned in the lesson. They might ask questions like:

   • "What was the most important concept you learned today?"
   • "Which questions have not yet been answered?"
   • "How can you apply what you've learned about ecosystem services in your daily life?"

4. Assessment of Learning: Based on the students' responses, the teacher can gauge the effectiveness of the lesson and identify any areas that may need further clarification or reinforcement in future lessons. This reflection can also provide valuable insights into the students' understanding of the topic and their ability to apply the concepts in real-world situations.

5. Homework Assignment: To reinforce the day's learning, the teacher can assign a short homework task. For example, students could be asked to write a reflection paper on the most important thing they learned about ecosystem services and its implications for their daily life. This would provide an opportunity for students to consolidate their learning and express their thoughts in a more personalized way.

6. Closing Remarks: The teacher will conclude the lesson by thanking the students for their active participation and encouraging them to continue exploring the fascinating world of ecosystem services. They might say, "Remember, each of us has a role to play in protecting and preserving our ecosystems and the valuable services they provide. I hope today's lesson has inspired you to make more informed choices and take actions that are beneficial for both our planet and our future."

This feedback stage will not only serve as a wrap-up for the lesson but also as a platform for students to reflect on what they've learned, ask any lingering questions, and consider how they can apply their knowledge in their daily lives.

Conclusion (5 - 7 minutes)

1. Summary and Recap: The teacher will begin by summarizing the main contents of the lesson. They will reiterate the definition and importance of ecosystem services, the different types of services, and the impacts of human activities on these services. They will also recap the activities performed during the lesson, emphasizing the key insights gained from each. The teacher's goal is to ensure that all students have a clear understanding of the main concepts and their practical application.

2. Connecting Theory, Practice, and Applications: The teacher will then explain how the lesson connected theoretical knowledge with practical activities and real-world applications. They will highlight how the Ecosystem Services Market Game and the Ecosystem Services Role Play allowed students to apply their understanding of ecosystem services and see their impacts in a tangible way. They will also emphasize how the lesson's discussions and reflections encouraged students to think about the real-world implications of their actions on ecosystem services. This will help students appreciate the relevance and importance of the topic in their everyday lives.

3. Additional Materials: To further enrich the students' understanding of the topic, the teacher will suggest additional materials for them to explore. These could include documentaries like "The True Cost" (about the environmental and social impacts of the fashion industry) and "A Plastic Ocean" (about the global issue of plastic pollution), or articles from reputable sources like National Geographic and the World Wildlife Fund's websites. The teacher could say, "I encourage you to continue learning about ecosystem services and the impacts of human activities on them. These materials will provide you with more in-depth information and different perspectives on the topic."

4. Relevance for Everyday Life: Finally, the teacher will reiterate the importance of the topic for students' everyday lives. They will explain that understanding ecosystem services can help them make more informed decisions that are beneficial for both the environment and themselves. For example, knowing that forests provide important ecosystem services like climate regulation and habitat for many species, students might choose to support organizations that work to protect and restore forests. The teacher could say, "Remember, small actions can make a big difference. By being aware of how our actions can impact ecosystem services, we can all contribute to a more sustainable and healthier planet."

The conclusion stage is important for wrapping up the lesson, reinforcing the main learning points, and guiding students towards further exploration of the topic. It also serves to underscore the relevance of the topic for students' lives, helping them understand why it is important to learn and care about ecosystem services.
