NOAA/Earth System Research Laboratory

This activity from NOAA Earth System Research Laboratory introduces students to the scientific understanding of the greenhouse effect and the carbon cycle. The activity leads them through several interactive tasks to investigate recent trends in atmospheric carbon dioxide. Students analyze scientific data and use scientific reasoning to determine the causes responsible for these recent trends. By studying carbon cycle science in a visual and interactive manner, students can learn firsthand about the reasons behind our changing climate.

Activity takes about four 45-minute class periods or one 3-hour lab period.

Teaching Tips

  • Make a worksheet with the questions posed after each step of the task to give students a place to write their answers. Some students may need a similar worksheet for the Basics section.
  • Educators may want learners to begin with an exploration of the visualization http://www.esrl.noaa.gov/gmd/ccgg/carbontracker/ to look for trends before they launch into the reading.
  • Different locations can be assigned to different groups to reduce the repetitiveness of the activity as described.
  • Video on "What's in the Air" about NOAA’s Carbon Cycle Greenhouse Gases group can help provide background on the program: http://www.esrl.noaa.gov/gmd/education/intheair.html

About the Science

  • A very thorough look at actual data to explore the carbon cycle and trends in CO2 concentration at different sites.
  • Comment from expert scientist: The "Basics of the Carbon Cycle and the Greenhouse Effect" web page consists completely of facts introducing the reader to the carbon cycle and the main sources of carbon dioxide in the atmosphere. The activity itself uses primary data measured at various sites around the world and draws from the databases that I will be using myself in a couple of weeks for my own research. I think that this makes this activity very powerful as students get to work directly with the data. It also makes students compare data from various locations and makes them realize that there are seasonal cycles as well as long term trends. Students can use the knowledge they learned from the basics page to understand the observations.

About the Pedagogy

  • More structure may be necessary for some students when reading the Basics of Climate Science.
  • There is no space or opportunity to write the answers to the questions posed during the activity.
  • Tasks are clear and easy for students to follow; screen shots are helpful.
  • A long reading kicks off this activity but it is well done.
  • The visualization is strong and fairly ease to use. The directions given to learners are clear and should be easy to follow.

Technical Details/Ease of Use

  • Easy for students to follow directions to find and analyze data.
