Objectives (5 - 7 minutes)

1. Understand the Concept of Aquatic Biomes: Students will be able to define and explain what aquatic biomes are, including the various types such as freshwater and marine biomes. They will learn about the different factors that impact these biomes, including temperature, light, and nutrient availability.

2. Identify the Flora and Fauna of Aquatic Biomes: Students will be able to identify the different types of plant and animal life that exist within aquatic biomes. They will learn about the unique adaptations of these organisms that allow them to survive and thrive in water environments.

3. Recognize the Importance of Aquatic Biomes: Students will understand the crucial role that aquatic biomes play in the global environment. They will learn about the services that these biomes provide, such as nutrient cycling, climate regulation, and habitat provision for numerous species.

Secondary Objectives:

• Develop Research and Presentation Skills: Due to the flipped classroom methodology, students will be responsible for conducting their research and preparing a short presentation on a specific aquatic biome. This will help them to develop their research skills and their ability to effectively communicate their findings.

• Encourage Collaborative Learning: As part of their research and presentation, students will be required to work in small groups. This will foster a collaborative learning environment, promoting teamwork and communication skills.

Introduction (10 - 12 minutes)

1. Review of Necessary Knowledge: The teacher starts the lesson by reminding students of the basic concepts they need to understand aquatic biomes. They review the definitions of biomes and ecosystems, emphasizing the differences between terrestrial and aquatic environments. Students are also reminded of the importance of biodiversity and the roles of plants and animals in ecosystems. (3 minutes)

2. Problem Situations: The teacher presents two problem situations to engage students and stimulate their curiosity about the topic.

   • Problem 1: "Imagine you are a polar bear living in the Arctic, and suddenly the ice starts melting due to rising temperatures. Where would you go? How would this affect your survival?"
   • Problem 2: "Suppose you are a fish in a pond, and due to excessive fertilizer use in nearby farms, the pond water becomes cloudy and full of algae. How would this impact your life and the lives of other organisms in the pond?" (4 minutes)

3. Real-World Context: The teacher relates the topic to real-world applications. They explain how understanding aquatic biomes is crucial for managing and conserving water resources, ensuring the survival of many species, and mitigating climate change. They also mention the role of aquatic biomes in supporting various industries, such as fishing, tourism, and pharmaceuticals. (2 minutes)

4. Topic Introduction: The teacher grabs the students' attention by introducing the topic in an interesting and novel way.

   • Curiosity 1: "Did you know that more than 70% of the Earth's surface is covered by water, but only about 2% of that is freshwater, and most of it is trapped in ice and snow? This makes freshwater one of the most precious resources on our planet!"
   • Curiosity 2: "Have you ever wondered how marine animals like whales or dolphins can survive in saltwater? They have special adaptations that help them conserve water and get rid of excess salt, just like camels in the desert!" (3 minutes)

By the end of the introduction, students should have a clear understanding of the importance of the topic and be eager to learn more about aquatic biomes.

Development

Pre-Class Activities (15 - 20 minutes)

1. Research and Note-taking: Students are assigned to research on aquatic biomes, specifically focusing on freshwater and marine biomes. They need to take notes on the characteristics, flora, fauna, and environmental factors affecting each biome. Resources such as textbooks, websites, and educational videos provided by the teacher should be used. (10 - 15 minutes)

2. Watching Educational Videos: After their research, students are required to watch a series of short, engaging videos that provide a visual understanding of the topic. These videos could depict different aquatic biomes and the life forms that dwell in them. The teacher will provide the links to these videos. Students should take additional notes while watching the videos to supplement their understanding from the research. (5 - 7 minutes)

In-Class Activities (25 - 30 minutes)

Activity 1: Aquatic Biome Showcase

1. Introduction to the Activity (2 minutes): The teacher explains that the class will be hosting an "Aquatic Biome Showcase" where each group will present their research findings about a specific aquatic biome. The presentation should include information about the biome's location, characteristics, flora, fauna, and the role it plays in the global environment. The teacher emphasizes that all group members should participate in the presentation.

2. Group Formation (2 minutes): The teacher divides the students into small groups of no more than five people. Each group is assigned a specific aquatic biome (e.g., Amazon River, Great Barrier Reef, Lake Baikal) to research and present on. Each group is provided with a resource packet containing relevant information about their assigned biome, which includes resources from the pre-class activities.

3. Research and Preparation (8 - 10 minutes): In their groups, students review their assigned resources, discuss the information, and prepare a short presentation. The teacher circulates the room, guiding students, clarifying doubts, and ensuring they understand the information.

4. Making Visual Representations (8 - 10 minutes): In addition to their presentations, each group is asked to create a visual representation of their biome. This could be a poster, a diorama, or a digital presentation. The visual should accurately depict the key features of the biome and the organisms that inhabit it. Students are encouraged to be creative and use the materials available in the classroom.

5. Presentations and Showcase (5 - 7 minutes): Each group presents their research and visual representation to the class. They explain the unique characteristics of their biome, the challenges faced, and the adaptations of the organisms that live there.

Activity 2: Biome Map and Discussion

1. Introduction to the Activity (2 minutes): Following the presentations, the teacher explains that the class will create a collaborative "Aquatic Biome Map." The map will include a visual representation of each biome presented, with the unique flora and fauna labeled.

2. Creating the Biome Map (10 - 12 minutes): The teacher provides a large world map on the board or a digital platform. Each group is tasked with adding their biome to the map, including the name, location, and a small visual representation. Then, they add the unique flora and fauna found in their biome, labeling them accordingly.

3. Discussion and Conclusion (5 - 7 minutes): After all the biomes are added, the teacher facilitates a class discussion. Students are asked to compare the different biomes, discussing the similarities and differences in terms of environmental conditions and the life forms present. The teacher concludes the discussion by summarizing the key points and highlighting the diverse nature of aquatic biomes and their importance in the global environment.

By the end of the development stage, students should have a comprehensive understanding of the different types of aquatic biomes, the life forms they support, and the environmental factors that influence them.
