Essential question How is Earth's climate connected to its geological, biological and cultural systems?

  1. Geology affects the Earth’s climate in various ways. Mountains can cause the sky to drop its rain before it reaches the land on the other side. Oceans help to create wind currants that carry vital moisture inland. Volcanic activities have helped to create a yearlong winter in the not so distant past. The plant life helps to stabilize our atmosphere by pumping oxygen into it. Humans inadvertently help to heat our planet by pumping more carbon dioxide into the atmosphere than the plants can take out.

    “*Why are carbon dioxide concentrations increasing in our atmosphere?” Ever since the Industrial Revolution we humans have been putting ever-increasing amounts of carbon dioxide into the open. Especially with the advent of gas powered and oil lubricated vehicles. Then there is all of the extra things we like that must be powered somehow and not always in eco-friendly ways. We are also cutting down more and more trees and putting more and more concrete in their place.

    “*What are some ways Earth naturally stores carbon dioxide?” The Earth naturally stores carbon dioxide in living plants, the ocean, and oil and coal. By removing living plants, digging coal, and pumping oil we are releasing the carbon back into the atmosphere much faster than if it was left to do naturally.

    “*How useful are these resources for shining two lights on the same path?”
    This module was interesting in its own way but I have found other modules much more to my liking and understanding. Probably, because of this, I would have a hard time explaining/ teaching the first part of this module to my students. As fourth graders we haven’t even touched on the elements in a truly meaningful way yet. I’m not too sure they have learned much about space either or the big bang theory.

  2. Glad I found this post. I missed it in my earlier passes. It might be challenging to explain nuclear fusion to 4th graders, but then again, we're often surprised by kids...; )
