This is not a productive attitude. You could tell the kids that all the "facts" taught in science class are the best currently available explanations for phenomena. In the case of evolution, you could present a list of phenomena that would have to be explained by any competing theory. You could also present a list of authors like Gould, Eldredge and Mayr, who have argued the case in layman's terms. For all I care you could mention Behe and Dembski.
It's very touchy when you get into those areas. More than likely, where I taught I could have taught ID if I had wanted to and never gotten in trouble (because we were in a pretty fundamentalist area). However, I could also have gotten into big trouble. My personal feeling is that, I am a teacher, not their parent, and it's not my job to teach them what to believe. But, it could actually be quite the teachable moment, because the kids were keenly interested, but wanted to talk about GOD and the Bible.

Behe testified under oath that the reason we didn't see evolution ID changes now is because God may be dead.
