Honestly covering both in a bio class is entirely do-able, since the Creation part would only take about ten minutes to say everything there was to say about it, since there really isn't any theory or proof to it, it's entirely a matter of faith. Most of what passes for teaching about it boils down to either promoting a particular religion or picking holes in the so-called theory of evolution. Faults or missing elements in the predominant scientific theory should certainly be fully covered in teaching about it, but they don't prove any other particular theory.
Creation isn't unique to Christianity or Evangelical Christianity, every religion has some form of creation story. Teaching only the Judeo-Christian version would be promotion of a particular religion over others, and public schools can't go down that road.
I'd send them to the Museum of Natural History, and if I were free to do so, tell them that there were alternate interpretations to what they were seeing, including that a higher Power had chosen to make it that way, and it was up to them to see and decide for themselves.
