Science lessons are not always comprised of undisputed fact

Science doesn't proclaim to produce 'facts', so much as it claims to produce verifiable, empirical ways to measure and disprove hypotheses. This is known as the scientific method. Things that can be measured, and disproved have a place in science. Apart from the existence of holy books, and people's insistence, there is no evidence to the existence of a divine being or God. One of the main arguments creationists use is that it is implasuable that such advanced creatures as human beings evolved through evolution. However, they offer no demonstrable theory of how a divine being would be able to manipulate matter, to create us out of thin air either. An example of evolution of a virus was demonstrated scientifically recently, when the swine flu virus became able to infect humans. Rational theories of evolution are constantly demonstrated throughout the world, and so far Darwin's theory has never been disproven. the great thing about science is, so long as someone shows effective research and scientific method, anyone can disprove his theory once and for all. If this happens, then science can continue in another direction. Religious people should read his theory in full before they reject it out of hand though - there is a great deal of misunderstanding about Darwinism amongst religious people. Indeed, he himself was a religious man, and it took a great deal to convince him of the likelihood of evolution. It is never possible to 'prove' something beyond all doubt in science, there is always doubt, and that doubt is celebrated. This is what gives us new hypotheses, which become new theories when they cannot be disproven. This is what moves us forward instead of backward. Another example is the belief that the world was flat. Many, many people believed this, just because of their own experiences. Science could disprove this theory by using rational analysis of geography and star positioning. In fact, standing on a tall mountain or getting in a plane can show you the curvature of the earth, but it is amazing how angry people were when that theory first came about. The existence of a divine creator can never be disproved, because it is based purely on belief, not on empirical, observable evidence. If a Harry Potter book was dug up in two thousand years, just because lots of people liked Harry Potter stories, doesn't mean that he ever really existed as a real person. In contrast, we can demonstrate how less evolved species developed through the finding of fossils, through genetics, and through the understanding of the process of gene propagation. It's nice to believe in something, and have faith in higher purpose or meaning, but faith is contrary to scientific method. An example is some parent's faith in the massively discredited theories to do with the MMR jab's link with autism. No serious scientists agreed with this inherently flawed research, yet it influenced thousands of people, and is now having the net effect of increasing the spread of measles (a potentially fatal disease). This an example of hearsay, and faith in a particular source (in this case, Newspapers and TV) outweighing all evidence to the contrary. Almost all religous arguments are based on faith - not on evidence. If creationism is to be taught in science lessons, it can only be fairly taught with the demonstration of the absence of scientific method, sound research, solid theories and empirical evidence. It is a good example to students of how not to partake in scientific argument and observation. Just because you want to believe something with all your heart, doesn't make it a scientific theory.
