Rubric: - Accurate observation and classification of rock samples (10 points) - Understanding of the formation and significance of landforms (10 points) Assessment questions: 1. How are igneous rocks different from sedimentary rocks? 2. What processes contribute to the formation of landforms? Activity 4: Demonstrating Understanding of the Biosphere Materials: - Textbooks or online resources - Poster boards or presentation software - Art supplies (markers, colored pencils, etc.) Instructions: 1. Divide the class into small groups and assign each group a specific biome (e.g., rainforest, desert, tundra). 2. Instruct each group to research and gather information about their assigned biome, including its characteristics, climate, vegetation, and animal life. 3. Encourage students to use different sources, such as textbooks, online resources, and scientific journals, to gather comprehensive information. 4. Once the research is complete, have each group create a poster or digital presentation showcasing their biome. 5. Instruct the groups to include visuals, such as drawings or photographs, to represent the flora and fauna of their assigned biome. 6. Each group should present their poster or digital presentation to the class, explaining the unique features and importance of their biome. Rubric: - Research and gathering of information (5 points) - Representation of biome characteristics and life forms (5 points) - Clarity and effectiveness of presentation (5 points) Assessment questions: 1. What are the main characteristics of the assigned biome? 2. How does the flora and fauna in the biome adapt to its specific environment? Activity 5: Investigating the Interactions within the Biosphere Materials: - Ecosystem models or diagrams - Index cards or sticky notes - Writing utensils Instructions: 1. Provide students with ecosystem models or diagrams that depict various interactions within the biosphere, such as predator-prey relationships or symbiotic partnerships. 2. Instruct each student to choose one interaction and write a brief description of on an index card or sticky note. 3. Once the descriptions are complete, have the students place their cards or notes on a larger display board or wall, arranging them in a way that shows the interconnectedness of the interactions. 4. Encourage students to discuss and analyze the relationships between different interactions, identifying how changes in one interaction can impact others. 5. Facilitate a class discussion on the importance of maintaining balanced ecosystems and the consequences of disrupting these interactions. Rubric: - Accurate description of the chosen interaction (5 points) - Placement and arrangement of cards/notes to demonstrate interconnectedness (5 points) - Active participation and contribution to the class discussion (5 points) Assessment questions: 1. How do predator-prey relationships contribute to maintaining ecosystem balance? 2. Give an example of a symbiotic relationship and explain how it benefits both organisms involved. Activity 6: Analyzing Human Impact on the Biosphere Materials: - Case studies or articles on human activities affecting the biosphere - Graphic organizers or worksheets Instructions: 1. Provide students with case studies or articles that highlight different human activities impacting the biosphere, such as deforestation, pollution, or climate change. 2. Instruct students to read and analyze the case studies or articles, identifying the specific human activities and their effects on the biosphere. 3. Have students complete a graphic organizer or worksheet where they categorize the activities into different types of impacts, such as habitat destruction or biodiversity loss. 4. Encourage students to propose possible solutions or actions that individuals or communities can take to mitigate the negative impacts and promote the conservation of the biosphere. 5. Facilitate a class discussion where students share their findings and solutions, emphasizing the importance of individual and collective responsibility in protecting the biosphere. Rubric: - Analysis and identification of human activities impacting the biosphere (5 points) - Categorization of impacts and proposed solutions (5 points) - Active participation in the class discussion (5 points) Assessment questions: 1. What are the main human activities that contribute to habitat destruction? 2. How can individuals contribute to the conservation of the biosphere in their daily lives? Explain: 1.

Show diagrams and models to help students visualize the structure and functions of the hydrosphere, geosphere, and biosphere. Elaborate: 1. Organize a field trip to a local ecosystem, such as a forest or wetland, where students can observe the interactions between the biosphere and other Earth systems. 2. Assign group projects where students research and present on the impacts of human activities on the atmosphere, hydrosphere, geosphere, and biosphere. Evaluate: 1. Administer a written test assessing students' understanding of the atmosphere, hydrosphere, geosphere, and biosphere. 2. Assign a project where students create a model or infographic illustrating the interconnectedness of the Earth systems. Extend: - Encourage students to explore current environmental issues related to the atmosphere, hydrosphere, geosphere, and biosphere and propose solutions in their communities. Assignment: Write an essay discussing the importance of preserving the Earth's systems (atmosphere, hydrosphere, geosphere, and biosphere) for future generations. Include specific examples and propose actions that individuals can take contribute to the preservation of these systems.
