Science is both a body of knowledge that describes order in nature and a way to discover that knowledge through experimentation.
A scientific fact is an observation agreed upon by competent observers.
A hypotesis is an educated guess as to the cause and effect of a phenomenon.
For this to be a validscientific hypotesis, one must be able to prove it false.
A scientific theory applies to a synthesis of a large body of information that has been tested, validated and accepted by a large number of scientists.
A scientific Law or Principle on the other hand has also been tested and accepted, but usually involves only 1 principle or concept.
A scientific model is useful for designing experiments and making predictions to determine whether or not a particular concept or relationship is true.
The process of finding new scientific knowledge is called the scientific method.
