Science is what scientists do.
They need to have a reason for deciding which kinds of facts to look for and what the facts might be about. So actual science is not a neat set of ordered steps, but much more a question of making up your methods as you go. Biologists collected lots of information about different species, and how they survive, long before there was any theory of evolution to explain how it all works. It was several years later before anyone thought of an experiment that could be performed to test his theory. So there is no clear set of steps in a certain order that can adequately describe what scientists do.
