How can I distinguish the similarities and differences of scientific theory and scientific law?

 Fact  An observable and measurable phenomenon.  Theory  An explanation of a phenomenon that is supported by facts.  Law  A rule that describes a pattern in nature.

 Fact  An observable and measurable phenomenon.  Examples of scientific facts: the number of ribs in a squirrel's body the average speed of a horse the weight of a paper clip

An ATTEMPT to explain a pattern that occurs over and over again is called a scientific theory. Theories must be supported by facts and tested many times. Theories are the best explanations to a problem that we have so far. They are not necessarily right and they can change.

The big bang theory Theory of General Relativity An explanation of a phenomenon that is supported by facts.

A RULE that describes a pattern is called a scientific law. For something to become a law, it must be tested and tested many times to be sure it is correct. Laws are different from theories because they don’t tell why something happens, or how it happens. Laws just simply describe it happening. Laws do not usually change.

Newton’s first of the three laws states an object in motion stays in motion unless acted upon by an outside force.
