How old are you? Maybe 40 years ago, but science is a big part of cirriculum now; they even teach about evolution, although not from a human standpoint. Just because you believe in God doesn't meant you don't believe in tectonic shifts, dna, biology, geology, fossils, hatching of eggs, emergence of butterflies, etc..

Welp, you're spelling of curriculum doesn't help your cause, but to answer your question I'm only 25.
I went to Catholic school from the age 8-13, which is when my parents took me out and I transferred to another school.
It's not that they don't teach it, it's that most of them don't believe in it, and therefore don't do a thorough job of explaining it.
