Introduction (10 - 15 minutes)

1. The teacher begins the lesson by reminding students of prior knowledge related to ecosystems. This includes a brief review of the definition of an ecosystem (a community of living organisms and their physical environment interacting as a system) and the components of an ecosystem (biotic - living components, and abiotic - non-living components). The teacher may use a visual aid, such as a diagram of an ecosystem, to help students recall these concepts. The teacher should also ask a few probing questions to ensure that students have a good understanding of these foundational concepts.

2. The teacher then presents two problem situations to the students to stimulate their thinking about the topic.

   • Problem 1: The teacher describes a scenario where a group of people move into a forest and start cutting down trees to build houses and clear land for farming. The teacher asks, "What do you think will happen to the animals and plants in the forest as a result of this human activity?"
   • Problem 2: The teacher describes a different scenario where a community of people living near a river starts throwing their trash into the river. The teacher asks, "How do you think this will affect the water quality and the animals and plants that depend on this river?"

3. The teacher then contextualizes the importance of the subject by discussing real-world applications. The teacher can give examples of current environmental issues that are the result of human interactions with ecosystems, such as deforestation, pollution, and climate change. The teacher emphasizes that understanding these interactions can help us make more informed decisions and take actions to protect our environment.

4. To grab the students' attention, the teacher introduces the topic with two intriguing facts:

   • Fact 1: The teacher explains that our body is an ecosystem too, with billions of bacteria living in our gut and on our skin that help us digest food and protect us from harmful pathogens.
   • Fact 2: The teacher shares a story about the reintroduction of wolves in Yellowstone National Park, which led to a series of unexpected changes in the ecosystem, such as the recovery of aspen and willow trees and the return of several bird species. This story highlights the interconnectedness of species in an ecosystem and the potential for both positive and negative impacts of human interventions.

By the end of the introduction, students should have a clear understanding of what they will be learning, why it is important, and how it relates to real-world situations. They should also be curious and engaged, ready to learn more about human interactions with ecosystems.

Development (20 - 25 minutes)

Content Presentation (10 - 12 minutes)

1. The teacher begins this stage by presenting the "Ecosystem: Humans Interactions" topic. The teacher may use a PowerPoint presentation to aid the lesson, including images, videos, and infographics to make the content more engaging and help students visualize the concepts better.

2. The teacher reintroduces the concept of an ecosystem, highlighting its components as reviewed in the introduction. The teacher then explains that ecosystems are not just natural environments like forests or oceans but can also include man-made environments like cities or agricultural land.

3. The teacher continues by explaining that human interactions with ecosystems are a fundamental aspect of biology, as humans are a part of the ecosystem. The teacher highlights that these interactions can be both positive and negative, and understanding them is crucial for the long-term sustainability of both human societies and the environment.

4. The teacher then delves into different types of human interactions with ecosystems. The teacher uses the term 'Anthropogenic' to describe these interactions, explaining that it refers to all human activities, impacts, or processes occurring in nature.

5. The teacher presents the three types of Human-Ecosystem Interactions, as outlined below:

   • Human exploitation of ecosystems (e.g., deforestation, overfishing, mining): The teacher explains the negative impacts of these activities, such as habitat destruction, loss of biodiversity, and climate change.
   • Conservation of ecosystems (e.g., protected areas, wildlife sanctuaries): The teacher discusses how these efforts can help mitigate the negative impacts of human activities and protect biodiversity.
   • Cultural and spiritual interactions with ecosystems: The teacher explains how different cultures and societies have unique relationships with their environments, sometimes leading to beneficial or harmful impacts.

Activities and Discussions (10 - 13 minutes)

1. The teacher then facilitates a class discussion on each type of human interaction presented, encouraging students to share their thoughts, ideas, and examples they might think of. The teacher might use guiding questions to direct the discussion, such as:

   • "What are some examples of human exploitation of ecosystems that you are aware of?"
   • "Can you think of any cultural practices that might help conserve ecosystems?"
   • "How can we balance our need to use natural resources with the need to protect the environment?"

2. To further illustrate the concepts, the teacher proposes two interactive activities:

   • Activity 1: The teacher divides the class into groups and assigns each group one of the three types of human-ecosystem interactions. The groups are asked to brainstorm and create a poster illustrating examples and impacts of their assigned interaction. After creating the posters, each group presents their findings to the class.
   • Activity 2: The teacher uses a case study. The teacher presents a real-world case study of a human interaction with an ecosystem (e.g., the impact of palm oil production on rainforests and orangutans). The students are asked to analyze the case study and discuss in groups the possible impacts, both positive and negative, of this interaction.

3. After the activities, the teacher brings the full class together for a wrap-up discussion. The teacher asks students to share what they learned from the activities and to reflect on the complexity of human interactions with ecosystems. The teacher also encourages students to think about how they, as individuals, can contribute to more sustainable interactions with the ecosystem.

By the end of the development stage, students should have a thorough understanding of the different types of human interactions with ecosystems and their impacts. They should also have the ability to analyze real-world scenarios and form their opinions on sustainable human-ecosystem interactions.

Feedback (8 - 10 minutes)

1. The teacher begins the feedback stage by summarizing the main points of the lesson. The teacher may use a graphic organizer, such as a concept map or a Venn diagram, to visually represent the interconnectedness of the different components of the lesson. This helps students see how the different parts of the lesson fit together and reinforce their understanding of the topic.

2. The teacher then encourages students to reflect on what they have learned. The teacher asks:

   • "What was the most important concept you learned today?"
   • "How do you think this lesson will impact your daily life and decision-making?"
   • "What questions do you still have about human interactions with ecosystems?"

3. The teacher allows students a few minutes to think about these questions and then opens the floor for discussion. Students are encouraged to share their thoughts and insights. The teacher should actively listen and provide feedback on the students' responses, guiding them to deeper understandings where necessary.

4. The teacher then assesses the students' understanding of the lesson's objectives. This can be done through informal methods such as a show of hands or a quick verbal quiz. The teacher asks questions related to the main concepts of the lesson, such as:

   • "Can you give an example of human exploitation of an ecosystem and its impact?"
   • "How are cultural and spiritual interactions different from human exploitation and conservation of ecosystems?"
   • "Why is it important for us to understand and manage our interactions with the ecosystem?"

5. The teacher also provides feedback on the activities conducted during the lesson. The teacher highlights the key insights from the group discussions and the case study analysis, and how these activities helped the students understand the topic better. The teacher also addresses any misconceptions that may have arisen during the activities.

6. The teacher concludes the feedback stage by encouraging students to continue thinking about the topic and to explore it further on their own.
