This activity is part of the Carbon Trackers unit.
- Remind students of the unit’s driving question: Where does the energy in fossil fuels come from and where does it go?
- Ask each student to take five minutes to write down their response to that question (using a diagram if needed).
- Follow up with a class review of the Know & Need to Know chart and the initial carbon cycle model from the Tracking Down the Carbon activity.
- Direct students to evaluate their collective learning through this unit by asking: Have we learned all we needed to know and resolved all of the initial questions from the model?
- Explain that the goal for the activities in this lesson is to use all of the information and knowledge the students have gathered to prepare a presentation for the target audience. This is reflected in the lesson driving question: How can we use our models to educate and inspire others to understand the importance of matter and energy cycling on Earth?
- Review class notes from the end of the Matter and Energy Cycles: Modeling activity about how to combine all of the cycles, as well as students’ ideas from the Greenhouse Effect activity about how the greenhouse effect should be incorporated into their model.
- Review the Cycle Model Rubric and explain that it will be used to assess the success of the final model and the associated presentation.
- As the rubric states, the goal is to create a thorough, complete model of the carbon cycle with all processes labeled properly, with arrows in the correct direction(s), with all reservoirs included, and with all sub-cycles clearly integrated.
- The model should be organized and be used to simplify a complex process for the audience. It needs to be visually appealing and effective to help others easily understand the information.
- Split the students into four groups, each one representing one of the reservoirs: lithosphere, atmosphere, biosphere, and hydrosphere. If your class is large, you can assign the same reservoir to two groups and then have them collaborate to compare and check their work.
- Each group should spend 5-10 minutes sketching or listing the major processes and components of their assigned reservoir. Their illustration will include components and processes of one or more of the sub-cycles researched in Matter and Energy Cycles: Research and other processes and components from the initial carbon cycle model from Tracking Down the Carbon.
- Based on their sketch or list, direct each group to create their portion of the model in about 30 minutes, remaining cognizant of how their section will visually and conceptually link to the others. If you’ve doubled up on groups, have the groups combine about halfway through the allotted time to compare and agree on a single model.
- When students have completed their segment, assist the groups in connecting the reservoirs.
- You may want to start with pairing two reservoirs first before connecting them all.
- This will require some additional work, depending on the medium students use to construct their model, such as drawing arrows to connect reservoirs and adding labels.
- Keep in mind that this part of the activity will be complex and will require thinking on your feet and adapting for your particular class size and students.
- Display the final model for the whole class to: 1) critique how the ideas are visually displayed and communicated, and 2) use the Cycle Model Rubric to ensure that the model meets the first row of criteria.
- This is not intended as a way to grade individual students or groups, but for the purpose of collaboratively refining and polishing the final piece to be optimally successful for the presentation.
- If students notice any mistakes or missing pieces, provide time for the class to discuss and correct those now so that the model is complete at the end of this activity.
- Ask students to provide one to two ideas in response to the following questions:
- Describe what matter and energy cycling is, and why matter and energy cycles are important for the Earth as a system. Why are they important to living things?
- What are fossil fuels? Where do they come from? How are they made?
- How are they extracted and used? When used, where does the energy and matter in them go?
- How does the use of fossil fuels by humans impact the normal matter and energy cycles?
- How does carbon move through the large Earth system?
- Why is understanding Earth’s matter and energy cycles important?
- The driving question for this lesson: How can we use our models to educate and inspire others to understand the importance of matter and energy cycling on Earth?
- What are the limitations of our class model?
Collect the responses to the homework questions and return your feedback the following day at the start of the next activity. That will enable students to have feedback before they do the final presentation.

- ESS2.A: Earth Materials and Systems: All Earth processes are the result of energy flowing and matter cycling within and among the planet’s systems. This energy is derived from the sun and Earth’s hot interior. The energy that flows and matter that cycles produce chemical and physical changes in Earth’s materials and living organisms. The planet’s systems interact over scales that range from microscopic to global in size, and they operate over fractions of a second to billions of years. These interactions have shaped Earth’s history and will determine its future.
