Global patterns in Green-up and Green-down
http://www.globe.gov/documents/356823/356868/earth_la_seaphen_p6.pdf

GLOBE Program

In this classroom activity, students analyze visualizations and graphs that show the annual cycle of plant growth and decline. They explore patterns of annual change for the globe and several regions in each hemisphere that have different land cover and will match graphs that show annual green-up and green-down patterns with a specific land cover type.

Activity takes about two to three class periods.

Climate Literacy
About Teaching Climate Literacy

The tilt of Earth’s axis relative to its orbit around the Sun results in predictable changes in the duration of daylight and the amount of sunlight received at any latitude throughout a year. These changes cause the annual cycle of seasons and associated temperature changes.
About Teaching Principle 1
Other materials addressing 1c
Life—including microbes, plants, and animals and humans—is a major driver of the global carbon cycle and can influence global climate by modifying the chemical makeup of the atmosphere. The geologic record shows that life has significantly altered the atmosphere during Earth’s history.

Benchmarks for Science Literacy

Because the earth turns daily on an axis that is tilted relative to the plane of the earth's yearly orbit around the sun, sunlight falls more intensely on different parts of the earth during the year. The difference in intensity of sunlight and the resulting warming of the earth's surface produces the seasonal variations in temperature.

Plants on land and under water alter the earth's atmosphere by removing carbon dioxide from it, using the carbon to make sugars and releasing oxygen. This process is responsible for the oxygen content of the air.

Teaching Tips

About the Science

  • Very good background material for educators.
  • Visualizations from space show students how scientists use data for analyzing global climate patterns.
  • Materials are dated; e.g. some of the maps and data sets are from the late 1980s. This doesn't take from the learning outcome but might discourage students.

About the Pedagogy

  • Use of grouping techniques and discussion to elicit student learning helps diverse students engage with activity content. Also, flip books are good for visual and tactile learners, and a good way for students to examine relationships in the data visually.
  • Well organized and structured for educators and students.
  • Provides clear and comprehensive guidance for educator.
  • Worksheets are provided along with rubrics for evaluation.
