Why might scientists change a scientific theory?
If a new theory better fits the data overall or simply because new and significant data disagrees or the method which brought about the original theory is invalid.
Under what conditions can a scientific model or theory change?
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.
What is a scientific theory that has been changed due to new evidence?
When new evidence is found, the theory is tested against the new evidence, if the theory and new evidence are compatible then the theory is confirmed, if the new evidence and the theory are not compatible, then this indicates the theory is wrong and the theory must be abandoned or modified. Sometimes a theory will predict that new things (evidence) will be discovered. In such cases when these things are discovered AS PREDICTED, the theory becomes stronger. For instance some of the outer planets were predicted (using orbital and gravitational theory and observation on the orbits of known planets) and they were later discovered close to where they were predicted to be.
What would best describe a theory?
A theory is a guess at what the result of something will be, based on what is already known about it. Theories will often remain unchanged, unless new evidence is found that suggests the theory is incorrect - if this is the case, the theory will be modified in order to better reflect the new evidence
How are scientific theories related to observations and evidence?
Scientist use scientific methods to test the new theory. They also examine all the evidence to see if it supports the new theory. Scientist accept a new theory when many test and pieces of evidence support it.

How long was it before new evidence emerged to support wegener's original theory?
In the 1960's scientists uncovered new evidence that seemed to support Wegener's theory.

Why is Einstein's theory of relativity an improvement on Newton's theory of gravity?
It will be replaced by a new theory when enough evidence is collected

What happens when new evidence does not support your theory?
Depends on whether all the theory is being contradicted or only a part of theory faces contradiction. For instance; the theory of evolution by natural selection would take a theory shaking hit if we found fossil rabbits in the Cambrian period, which has not happened. Only part of the theory of evolution by natural selection was contradicted by Mendelian genetics, when Mendel's much better heritability mechanism replaced Darwin's idea about blending inheritance. The theory only got stronger by this ratification.If that new evidence is solid enough, it may require a revision of the theory. If it is just shaky and occurs because of some error in the experiment, it is usually discarded as uncredible.
If new evidence does not support a scientific theory scientists will most likely?
modify the theory or discard it altogether.
Can the future cause a theory to be revised or discarded?
As new evidence is discovered it can cause a theory to be revised or discarded.

If a scientific theory changes does this mean that it was not a good theory to begin with?
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.
