Introduction: (10 - 12 minutes)

1. Review of Necessary Content: The teacher begins by reminding students about the basic concepts of ecosystems, biodiversity, and the balance of nature, which they have learned in previous units. The teacher can use a quick warm-up quiz or a brief discussion to gauge students' existing knowledge and prepare them for the new topic.

2. Problem Situations as Starters:

   • Situation 1: The teacher presents a scenario where a forest fire has wiped out all the vegetation in a particular area. The students are asked to predict what might happen in this area over the next few years.
   • Situation 2: The teacher describes a situation where a pond has been filled in for a construction project. Students are asked how they think the land will change over time and what types of species might move into this area.

3. Contextualization of the Subject: The teacher explains the importance of understanding ecological succession in the context of environmental conservation and management. The teacher can share examples of how this knowledge can help in the restoration of damaged ecosystems and in predicting the impacts of climate change on biodiversity.

4. Topic Introduction and Engagement: The teacher introduces the topic of Ecological Succession by showing a short, engaging video or animation that illustrates how an ecosystem changes and develops over time. The teacher then shares two interesting facts or stories related to ecological succession:

   • Curiosity 1: The teacher can share that the world’s tallest trees, the Redwoods, owe their existence to fire, a destructive force. Fire is a part of their ecological succession process as their seeds need the extreme heat to open and germinate.

   • Curiosity 2: The teacher can share the story of Mount St. Helens eruption in 1980. Despite the destruction, ecological succession has taken place, and the area is now home to many new species of plants and animals, demonstrating the resilience of nature.

Development: (22 - 27 minutes)

Pre-Class Activities: (10 - 12 minutes)

1. Watching a Documentary: Students should watch a short documentary or an informative video on ecological succession at home. This can be a video from a reliable source that clearly explains the concept and stages of ecological succession. The teacher should provide guidelines on what to focus on during the video, including the stages of ecological succession, factors influencing it, and example scenarios.

2. Reading an Article: The teacher should provide students with an article that further explains the concept and real-life examples of ecological succession. The article should be simple, clear, and engaging so students can connect with the topic. Students are expected to write a short summary or draw a simple diagram of ecological succession based on the reading.

3. Online Quiz: The teacher should share an interactive online quiz (available on educational platforms like Quizlet or Kahoot!) for computer or smartphone. This auto-correcting quiz tests students' understanding of the topic, ensuring they're prepared for the in-class activities.

In-Class Activities: (12 - 15 minutes)

1. Activity 1 - Ecological Board Game: The teacher presents a board game adapted to study ecological succession. The game captures the different stages of succession and the role of various species in these stages. Each student group is given a game board and pieces representing different species.

   1. The game begins by one group rolling a dice that represents a disturbance (fire, storm, human activity, etc.) which will determine the starting point of succession on their board.
   2. The groups then take turns rolling again to see which pioneer species (lichens, grass, shrubs, etc.) they can place on their board.
   3. The game continues with each group rolling the dice and adding new species, which leads to the gradual development of the ecosystem over time right up to the climax community.
   4. The game ends when the first group builds a stable climax community on their board. The group then explains their ecosystem's progression, describing the role of different species at each stage and any unique interactions that occurred.

2. Activity 2 - Ecological Succession Diorama: In this hands-on activity, the teacher instructs each group to create a three-dimensional diorama of an ecological succession process using craft materials provided (cardboard, colored paper, clay, paint, etc.).

   1. The students begin by discussing and choosing a type of ecosystem for their diorama (a forest, a pond, a coral reef, etc.).
   2. They then divide and illustrate the stages of ecological succession on their diorama base, showing how the ecosystem develops from barren land/water to a multilayered climax community.
   3. Each group member takes charge of one or more stages, crafting representative species and adding them to the relevant stages in the diorama.
   4. Once completed, each group presents their diorama, explaining the sequence and interaction of different species throughout the ecological succession process.

Remember, these activities are more than just fun games. They give students a deeper understanding of how species interact and how ecosystems evolve over time under different conditions. They also provide an opportunity for students to work collaboratively, communicate their ideas effectively, and use their creativity and critical thinking skills.

Feedback: (8 - 10 minutes)

1. Group Discussion and Sharing: (5 - 6 minutes)

   • Each group is given approximately 3 minutes to present their conclusions from the board game and the diorama to the class. They explain their understanding of the ecological succession process, the role of various species at different stages, and how disturbances can reset the succession process.
   • The teacher facilitates the discussion, ensuring that each group gets an opportunity to present their work and ideas. The teacher also encourages other students to ask questions and provide constructive feedback on the presentations.
   • The teacher highlights key points and corrects misconceptions, if any, ensuring that the students understand the complexity and dynamics of ecological succession.

2. Connection with Theory: (2 - 3 minutes)

   • The teacher emphasizes how the activities connect with the theoretical concepts of ecological succession. For example, the board game illustrates the randomness and unpredictability of disturbances and the role of pioneer species in initiating the succession process.
   • The diorama provides a visual representation of the gradual change in an ecosystem, demonstrating how biodiversity and complexity increase over time and how different species interact and influence each other's survival.
   • The teacher also stresses that ecological succession is not a linear or predictable process, and it can vary greatly depending on the specific conditions and interactions within an ecosystem.

3. Reflective Questions: (1 - 2 minutes)

   • The teacher proposes that students take a moment to reflect on their learning experience. They are asked to answer the following questions:
     1. What was the most important concept you learned today about ecological succession?
     2. Can you give an example of how ecological succession can be seen in your local environment?
     3. What questions or confusions do you still have about ecological succession?
   • These reflective questions encourage students to consolidate their understanding, connect their learning to real-world contexts, and identify areas where they may need further clarification or study.

Remember, feedback is not just about assessing students' understanding. It's also about acknowledging their efforts, appreciating their participation, and encouraging their curiosity. It's an opportunity for the teacher to gauge how well the students have understood the lesson and to identify any gaps or misconceptions that need to be addressed in future lessons.
