First Session
Physical Geology
Dale Easley
-
Syllabus and class requirements
-
What is education?
-
Seeing connections
-
Cause/Effect; models of reality
-
Examples:
-
expansion of continental glaciers leads to lowering of sea level which
leads to incising of Mississippi River
-
retreat of continental glaciers leads to rising sea level which leads to
infilling by sediment of Mississippi River valley
-
A well drilled beneath us allows us to see the change in sediment type
that corresponds to changing sea level
-
Non-scientific: magical thinking, superstition
-
Desired outcome: ability to synthesize and develop new models
-
Example models
-
mental illness
-
mental illness is caused by possession by evil spirits
-
mental illness is caused by abusive environments while young at home
-
mental illness is caused by biochemical imbalances
-
Global warming
-
The greenhouse effect
-
Historical models:
-
Global climate change leads to changing sea level
-
Sea level rise has been occurring naturally since the last ice age.
-
Global warming is being accelerated by human activities.
-
Making distinctions
-
Classification systems
-
Examples:
-
Three main types of rocks: igneous, metamorphic, sedimentary
-
Two main types of aquifers: confined and unconfined
-
Non-scientific: prejudice /pigeonholing
-
Desired outcome: increased number of possible actions/responses/choices
-
Example actions:
-
mental illness
-
exorcism
-
therapy
-
drugs such as Prozac
-
Global warming
-
Can choose to limit emissions of greenhouse gases
-
Can improve protection of coastal zones
-
Can increase insurance premiums in New Orleans
-
Can move to Canada
-
After UD
-
take responsibility for own learning
-
design your life rather than simply have it happen
-
