Systems and System Models: Observing Carbon Dioxide in the Atmosphere
This mini lesson provides a video on an ultra-high-resolution NASA computer model of how carbon dioxide in the atmosphere travels around the globe. Students will review the video and answer the following questions.
The video A Year in the Life of CO2 displays a high-resolution NASA computer model called GOES 5. This model has given scientists a new look at how carbon dioxide travels in the atmosphere. Plumes of carbon dioxide swirl and shift as winds disperse the greenhouse gas away from its sources. This video also illustrates the different levels of carbon dioxide in the northern and southern hemispheres of Earth. This includes distinct swings in global carbon dioxide concentrations as the growth cycle of plants and trees changes with the seasons.
Review the video and answer the questions that follow.

Teachers, these mini lessons/student activities are perfect "warm up" tasks that can be used as a hook, bell ringer, exit slip, etc. They take less than a class period to complete. Learn more on the "My NASA Data What are Mini Lessons?" page.
Teachers who are interested in receiving the answer key, please complete the Teacher Key Request and Verification Form. We verify that requestors are teachers prior to sending access to the answer keys as we’ve had many students try to pass as teachers to gain access.
Supported NGSS Performance Expectations
- MS-ESS3-5: Ask questions to clarify evidence of the factors that have caused the rise in global temperatures over the past century.
- HS-ESS3-5: Analyze geoscience data and the results from global climate models to make an evidence-based forecast of the current rate of global or regional climate change and associated future impacts to Earth's systems.
