SCIENCE & THE SCIENTIFIC METHOD

    "THE SCIENTIFIC METHOD"

    1.  Make careful observations.
    2.  Recognize and state problem.
    3.  Develop a hypothesis.
    4.  Make prediction to be tested.
    5.  Perform experiments (or make observations) to test prediction.
    6.  Results may support or refute the hypothesis;
        They can be used to generate other hypotheses and may contribute to development of a theory.

Pages 28-29:
    HYPOTHESIS:
    1.  is a proposed explanation
    2.  "A hypothesis is a tentative explanation."
    3.  "A good hypothesis exhibits the following:
            1)  It is reasonably consistent with all well-established facts.
            2)  It is capable of being tested;  that is, it should generate definite predictions, whether the results are positive
                 or negative.  Test results should also be repeatable by independent observers.
            3)  It is falsifiable, which means it can be proved false.
    4.  A hypothesis cannot really be proved true, but in theory (though not necessarily in practice) a well-stated hypothesis can
        be proved false.  If one believes in an unfalsifiable hypothesis (e.g., the existence of invisible and undetectable angels), 
        it must be on grounds other than scientific ones.
    5.  A hypothesis is not true just because some of its predictions (the ones we happen to have thought of or have thus far
        been able to test) have come true.  After all, they could be true by coincidence.  In particular, failure to observe a
        prediction does not make a hypothesis false, but it does not show that the hypothesis is true, either.

Page 32:
    THEORY:
    1.  A hypothesis supported by a large body of observations and experiments becomes a theory.
    2.  A good theory relates facts that previously appeared to be unrelated and that could not be explained on common ground.
    3.  A good theory grows as additioinal facts become known.  ...
 
    SCIENTIFIC PRINCIPLE:   A theory that, over a long period of time, has yielded true predictions and is thus almost
                                                  universally accepted  ...

    LAW:   This term is sometimes used for a principle judjed to be of great basic importance as is, for instance, the law of
                gravity or the law of biogenesis.
