What is the goal of science?
To discover patterns in nature
To use this knowledge to predict
Hypothesis

Scientific Method
Gathers facts though observation
To formulate hypothesis and theories
The systematic steps for the scientific method
Collect facts
Develop hypothesis
Test hypothesis
Re-examine, accept, reject, or change hypothesis
What are the interacting parts of the Earths dynamic system?
Atmosphere (Air)

Geosphere (Solid earth)
Hydrosphere (water)
Where can fresh water be found?
From groundwater or a spring
Layers of the geosphere
Crust (fuzzy outside)
Mantle (peach skin)
Outer Core (juicy inside)
Inner Core (pit)
Lithosphere
Solid, rigid, outer layer of the Earths Atmosphere
(100 km thick)
Asthenosphere
Solid, but mobile layer of Atmosphere located under the Lithosphere
