Scientific Hypothesis, Theory, Law Definitions - …
The is a theory, but guess what? When scientists use the word , it has a different meaning to normal everyday use. That's right, it all comes down to the multiple meanings of the word . If you said to a scientist that you didn't believe in evolution because it was "just a ", they'd probably be a bit puzzled.
What's the difference between Hypothesis and Theory
Some people think that in science, you have a , and once it's proven, it becomes a . That's not how it works. In science, we collect facts, or observations, we use to describe them, and a to explain them. You don't promote a to a by proving it. A never becomes a .
Tanner further explained that a scientific theory is the framework for observations and facts. Theories may change, or the way that they are interpreted may change, but the facts themselves don't change. Tanner likens theories to a basket in which scientists keep facts and observations that they find. The shape of that basket may change as the scientists learn more and include more facts. "For example, we have ample evidence of traits in populations becoming more or less common over time (evolution), so evolution is a fact but the overarching theories about evolution, the way that we think all of the facts go together might change as new observations of evolution are made," Tanner told Live Science.

Any scientific theory must be based on a careful and rational examination of the facts. Facts and theories are two different things. In the scientific method, there is a clear distinction between facts, which can be observed and/or measured, and theories, which are scientists' explanations and interpretations of the facts.

"The way that scientists use the word 'theory' is a little different than how it is commonly used in the lay public," said Jaime Tanner, a professor of biology at Marlboro College. "Most people use the word 'theory' to mean an idea or hunch that someone has, but in science the word 'theory' refers to the way that we interpret facts."

An important part of scientific theory includes statements that have observational consequences. A good theory, like Newton's theory of , has unity, which means it consists of a limited number of problem-solving strategies that can be applied to a wide range of scientific circumstances. Another feature of a good theory is that it formed from a number of hypotheses that can be tested independently.

Next time someone tries to tell you that evolution is just a , as a way of dismissing it, as if it's just something someone guessed at, remember that they're using the non-scientific meaning of the word. If that person is a teacher, or minister, or some other figure of authority, they should know better. In fact, they probably do, and are trying to mislead you.

A scientific theory is not the end result of the scientific method; theories can be proven or rejected, just like . Theories can be improved or modified as more information is gathered so that the accuracy of the prediction becomes greater over time.
