Chapter 3.4
Notes
How can we
distinguish science from nonscience?
·
Defining
science can be surprisingly difficult.
·
Science
comes from the latin scientia, meaning knowledge.
Hallmarks of
science #2
·
Science
progressed through the creation and testing of models of nature that explain
the observations.
Hallmarks of
science #3
·
A
scientific model must make testable predictions about natural phenomena that
would force us to revise or abandon the model if the predictions do not agree
wit observations.
What is a scientific
theory?
·
The
word theory has a different meaning in science than in everyday life.
·
In
science, a theory is not the same as a hypothesis
·
A
scientific theory must:
Explain a wide variety of
observations with a few similar principles.
Be supported by a large,
compelling body of evidence.
NOT have failed any crucial test of
its validity.
