Tuesday, March 15th: Connecting the Spheres

Class summary:

  1. Warm-up
  2. Cryosphere clarification
  3. Connecting spheres activity
  4. Homework

PART 1-Warm Up: What is the role (job) of each sphere? (Orange sheet)

PART 2- Cryosphere Clarification:  FACTS TO KNOW from http://nsidc.org/cryosphere/allaboutcryosphere.html

  1. The cryosphere are places where water is in its solid form, ice.
  2. Pcryosphere1eople most often think of the cryosphere as being at the top and bottom of our planet, in the polar regions: the Arctic and the Antarctic. But snow and ice are also found at many other locations on Earth.
  3. The cryosphere also exists in places far away from the cold poles, at high elevations. For example, the snow on Mount Kilimanjaro is in Africa. Frozen soil can be found high in the mountains of the United States, as well as in the northern reaches of Canada, China, and Russia.
  4. The cryosphere expands during the cold winter months. Seasonal areas of the cryosphere include places where snow falls, and where soil, rivers, and lakes freeze.
  5. Snow, ice, or both are key ingredients in every aspect of the cryosphere, including sea ice, glaciers, ice shelves, icebergs, and frozen ground.

PART 3- How do our spheres connect? 

  1. Labeling Your Observations
    • FullSizeRenderLook at the observations you made outside on your green observation sheet. In the left side column, label what sphere or spheres your observation takes place in. For example, “There is a smell of spring in the air,” would be the atmosphere. “The grass is wet from melting snow,” could be both the biosphere and the hydrosphere.
    • If you haven’t already done so, glue your INPUT items in your journal as shown on the right.
  2. Connecting Observations to Spheres
    • Working with a partner and using the Partner Capture Sheet, choose one observation and follow the instructions on the sheet.
    • Partners will then combine with another group and will choose one observation in which to sketch and fulling connect. See the example below:sphere connection journal
    • Once all groups have finished, we will do a ROOM TOUR to look at connections and make additions/edits if we can see any.


OUTPUT- top of page 11

Use your practice, notes, and ideas from today to do the following:
  • Draw a diagram/model that shows how a squirrel collecting acorns for the winter would be connected to Earth’s four spheres/systems: hydrosphere, atmosphere, lithosphere, and biosphere.
  • Explain those connections.
  • It must be able to fit in the upper half of page 11.
  • You may draw directly on the page OR you can draw on a separate paper.
  • Computer drawing and labeling is also accepted.
  • The exemplar ABOVE to help you with your thinking.
  • Handouts and experiences from class today.
