Susan Borland, Kathy East, Teressa Black, Kathie Klein, Bruce Howard, Challenger Learning Centers

In this activity, students read an article condensed from several NASA articles about the impact of deforestation on the atmosphere and answer review questions. They then use Google Earth and current NEO data to examine relationships between forest fires and atmospheric aerosols.

2 50-minute class periods

Climate Literacy
About Teaching Climate Literacy

Airborne particulates, called "aerosols," have a complex effect on Earth’s energy balance: they can cause both cooling, by reflecting incoming sunlight back out to space, and warming, by absorbing and releasing heat energy in the atmosphere. Small solid and liquid particles can be lofted into the atmosphere through a variety of natural and man-made processes, including volcanic eruptions, sea spray, forest fires, and emissions generated through human activities.

Environmental observations are the foundation for understanding the climate system. From the bottom of the ocean to the surface of the Sun, instruments on weather stations, buoys, satellites, and other platforms collect climate data. To learn about past climates, scientists use natural records, such as tree rings, ice cores, and sedimentary layers. Historical observations, such as native knowledge and personal journals, also document past climate change.

Teaching Tips

  • Educator should familiarize her/himself with the NEO site before using with students.
  • Take students through the NEO site before you begin.
  • Make sure each computer can utilize Google Earth.
  • Consider reversing the order of activities so that students use the Google Earth and NEO data sets before reading the article.
  • Article needs to be unpacked with discussion supplementary visuals etc. Or, instead of the condensed article, use the original ones that are included in the teacher's instructions, which have visualizations that help explain the content.

About the Science

  • Students use the NASA Earth Observations (NEO) website to download datasets and use Google Earth to open and view them. Students conduct data analysis by summarizing apparent relationships between variables such as Aerosol Optical Thickness and Water Vapor.
  • Comments from expert scientist: The resources they use (mainly from NASA) and the use of Google Earth is great, and will no doubt grab the students attention. It also shows students how to access good data, view it, and encourages them to explore.

About the Pedagogy

  • Strong set of teacher materials provided.
  • The reading is quite dense and includes a lot of complex information that could be potentially confusing to student readers - careful guidance of the students through the text may be necessary.
  • This activity will take several days or class periods to complete.

Technical Details/Ease of Use

  • Students may have trouble accessing NEO data and/or following the directions that follow. Careful guidance of students through the activity is needed.
  • Screenshots used in the technology instructions could be larger for easier viewing.
