Begin with an engaging question: 'What do you think happens to the carbon in a tree when it dies?' This question will spark curiosity about the carbon cycle.
Go to the LessonLearning Objectives
- Understand the role of carbon as a foundational element in all living organisms and its presence in different Earth systems.
- Explain the process of the carbon cycle and how it facilitates the movement of carbon among the atmosphere, biosphere, geosphere, and hydrosphere.
- Describe the role of photosynthesizing organisms in converting atmospheric carbon dioxide into carbon-based food.
- Identify how carbon is stored in different forms, such as in living organisms, fossil fuels, and as dissolved carbon in bodies of water.
- Discuss the impact of human activities on the carbon cycle, specifically through the extraction and burning of fossil fuels.
Introduction and Hook
Direct Instruction
Explain the role of carbon as a foundational element in all living organisms and its presence in different Earth systems.
Discuss the process of the carbon cycle, highlighting how carbon moves among the atmosphere, biosphere, geosphere, and hydrosphere.
Guided Exploration
Explore the role of photosynthesizing organisms in converting atmospheric carbon dioxide into carbon-based food.
Use diagrams to show how carbon is stored in different forms, such as in living organisms, fossil fuels, and as dissolved carbon in bodies of water.
Hands-On Activity
Conduct an experiment where students simulate the carbon cycle using simple materials to represent different Earth systems.
Have students create a model of the carbon cycle, labeling each part and explaining the movement of carbon.
Independent Practice
Check for Understanding
Facilitate a class discussion to review key concepts of the carbon cycle and its importance in Earth's systems.
Use formative assessment questions to gauge student understanding and address any misconceptions.
Review and Reflection
Encourage students to reflect on how human activities impact the carbon cycle, particularly through the extraction and burning of fossil fuels.
Have students write a short paragraph summarizing what they learned about the carbon cycle and its significance.
Assessment and Extension
Administer the 'Earth’s Spheres' assessment to evaluate students' understanding of the interconnectedness of Earth's systems.
Encourage students to explore further by researching the impact of carbon emissions on climate change.
