,What is science?
Science is to Know; It is a body of information about the material world which has been collected by
vigorous, critical, and collective methods which is subjected to continuous testing and retesting backed
by a supported hypothesis. Science cannot answer ethical or moral questions. Science is constantly
changing; as technology progresses, science also progresses. Scientific theories get tossed aside as
science evolves.
What is the difference between a hypothesis, a theory, and a law?
Theory is a hypothesis that has lots of evidence to prove it.
Hypothesis is statement or generalization without evidence.
Laws: Ultimate laws that evolved from a theory. I.e. E=mc2.
