4. Scientific Method Deduction – generalize from facts Induction – conclusion from generalizations (tautology) Scientific Method is Inquiry Nothing is ever “proven” –Make a Hypothesis –Design controlled experiment –Analyze results –Draw conclusions –Retest

5. Density Density = Mass/Volume (g/ml or g/cm 3 ) Archimedes 250 BC tested whether or not the King of Syracuse was cheated by a craftsman who replaced some of the gold in the King’s crown with silver.
