All the time. Whenever new evidence doesn't fit the model it has to be changed.
Yes. For example, in history people thought earth was flat. Now scientists know the earth is round.
no
it can be used to make predictions, we can change it, and we can learn from it. Hope this helps. :)
theory of evolution
A SCIENTIFIC THEORY is a well-tested concept that explains a wide range of observation. (IF YOU ARE USING THIS TO CHEAT ON YOUR SCIENCE HOMEWORK, THEN YOU'RE NOT ALONE) lol
a scientific theory is a well tested explanation for a wide range of observations of experiments in other words is an idea that makes sense.
scientific theory is a tested and proved behavior of a system, in a standard condition, not minding any internal or external factors.
No scientific theory ever challenged the theory of evolution.
A scientific model can change if new evidence is found. If the new evidence that has been found contradicts the model or theory then a scientific model or theory can change.
Yes
A scientific law is the description of a recurring event that occurs in nature. A scientific theory is an explanation of the law. The law does not change, but the theory may change when new data indicate that it needs to.
no
Yes a theory can be changed.
It can change if it is proven wrong, or if a new theory is proven more likely to be true.
yes you can, in theory. But it is very difficult to change an established 'ruling paradigm' (however incorrect).
whenever an experiment fails to confirm the theory it is no longer a theory ... it becomes a hypothesis
No. It means that it was the best theory supported at the time it was formulated. Theories can change if new scientific evidence provides new information.

Yes. If a scientific theory cannot be "falsified" - that is, proven to be not true - then it isn't "scientific". A scientific theory will always lead to some tests that can be performed. If the test fails - that is to say, if your theory doesn't behave in accordance with the experimental results - then we can say that the theory is "disproved". This is the problem with a lot of the "global warming" and "global climate change" hysteria; the computer models for climate change make a number of predictions, but the models don't behave as predicted. The global climate change theory is, if we judge by the results of the models, disproved.
