When we say science, we mean any of a number of sciences, each of which studies its own area. They can be closely related, like Physics and Mathematics; have areas of overlap, such as Computer Science and Biology; or they can be wildly different like Astronomy and Zoology.
Science relies on reason and evidence. In science, you may start out with a theory, but if the evidence does not support your theory, you reject your theory, not your evidence. You then use reason and your evidence to come up with a new theory.
There are fields and practices that claim to be scientific, but do not have the required scientific rigor. These are called Pseudosciences. They do not follow the Scientific method and their experiments are unverifiable or they do not have enough evidence for the conculsions they draw. A popular example of a pseudoscience is Astrology.
One of the defining features of science is the Scientific Method, which has several steps.
