Scientific Hypotheses Must be Testable • A scientific hypothesis must be TESTABLE. • It is more important that there be a means of proving a scientific hypothesis WRONG, rather than there be a means of proving it right.

The Scientific Attitude • In science, data and observations are based on facts to eliminate subjectivity. Fact: a close agreement between competent observers who make a series of observations of the same phenomenon

The Scientific Attitude • Laws and principles are based on repeatable observations that have withstood the test of time and rarely, if ever, change. Law or Principle: A hypothesis that has been tested over and over again and is not contradicted

The Scientific Attitude • Theories are not permanent. Theories change when there is irrefutable scientific evidence to support the change. Theory: a synthesis of a large body of information that encompasses well-tested and verified hypotheses
