2. Scientific Theories In science,
What is a scientific theory?
In science,
theory = a well-tested explanation that unifies a broad range of observations and hypotheses and that enables scientists to make accurate predictions about new situations.
In society,
theory = a hunch, a guess.

3. Scientific Theories
Evidence from many scientific studies may support several related hypotheses in a way that inspires researchers to propose a scientific theory that ties those hypotheses together.
In science:
Theory applies to a well-tested explanation that unifies a broad range of observations and hypotheses.
Enables scientists to make accurate predictions about new situations.
A useful theory that has been thoroughly tested and supported by many lines of evidence may become the dominant view among the majority of scientists.
But, no theory is considered absolute truth.
Science is always changing; as new evidence is uncovered, a theory may be revised or replaced by a more useful explanation.

4. Scientific Theories vs. Laws
Theory applies to a well-tested explanation that unifies a broad range of observations and hypotheses.
Is the explanation
More dynamic, complex
Contain many more ideas and hypotheses
Ex:
Law = A concise description of how the natural world functions.
= a specific descriptions of how some aspect of the natural world is expected to behave in a certain situation
Is the how come
THEORIES DO NOT BECOME LAWS OVER TIME
