In science there is no controversy! The "controversy" you want to teach is a product of religious believers attempting to force their beliefs into the field of science.
Your "controversy" is not appropriate in science classes; teach it in religious venues.
There is controversy in life, or all these CREVO threads wouldn't have thousands of posts. I don't live life in little bubbles and neither do kids (OK are we in the "Science" bubble or the "Religion" bubble?). All this is very appropriate for school classroom discussion, IMHO.
It's not a foriegn concept, they did it when I was in school.
