Science is the study of the natural world and how things work.
Dogma is a set of principles or tenets.
Science doesn't deal with morality, except where morality as a whole is studied by a branch of science. Science is effectively a collection of knowledge, NOT a belief system, no matter how strongly the religious right insists that it is.
Dogma deals directly with morality, particularly where morality and religion intersect. Dogma is a set of doctrines that deal with morality, effectively dogma dictates morality and IS a belief system.
See the difference? Science IS NOT a belief, Dogma IS a belief.
