I thought the following, from the Smithsonian National Museum of Natural History, answers this question quite well---nice and succinct. And I suggest people use it to explain to those here who may conflate the two, or simply have no idea of what they're talking about. The linked site also gives separate explanations of science and religion. It also has a nice piece on evolution, creationism, and ID. (scroll down the page).
"SCIENCE
Although science does not provide proofs, it does provide explanations. Science depends on deliberate, explicit and formal testing (in the natural world) of explanations for the way the world is, for the processes that led to its present state, and for its possible future. When scientists see that a proposed explanation has been well confirmed by repeated observations, it serves the scientific community as a reliable theory. A theory in science is the highest form of scientific explanation, not just a mere opinion. Strong theories, ones that have been well confirmed by evidence from nature, are an essential goal of science. Well-supported theories guide future efforts to solve other questions about the natural world.
RELIGION
Religions may draw upon scientific explanations of the world, in part, as a reliable way of knowing what the world is like, about which they seek to discern its ultimate meaning. However, testing of religious understandings of the world is incidental, implicit and informal in the course of the life of the religious community in the world. Religious understanding draws from both subjective insight and traditional authority. Therefore, some people view religion as based on nothing more than personal opinion or blind faith, and so, as immune to rational thought. However, this is an erroneous judgment. Virtually all of the historic religions include traditions of rational reflection."
