Computer Science is a Formal Science. It studies abstract concepts, logic, algorithms, etc., but with very real applications. Not to be confused with Natural Science which studies laws of Nature. But it is still a Science.
Computer science... differs from physics in that it is not actually a science. It does not study natural objects. Rather, computer science is like engineering; it is all about getting something to do something.
Richard Feynman, Feynman Lectures on Computation, 1970
Wikipedia—"Computer science is the scientific and practical approach to computation and its applications." You're likely referring to the practical approach. Many, however, take the scientific approach. The 2 are markedly different in that one group finds new things to do & the other how to use them
