Why do we believe in electrons, but not in fairies? by Benjamin Kuipers is another great piece that was brought to my attention by Ray Salemi. Just to give you an idea of what is in the piece, I have the following quote:
Science education is about teaching the scientific method, and about teaching some of the knowledge that the human race has acquired by applying the scientific method. It would be a useful part of a science class to teach the distinction between theories that are scientific because they make testable predictions, and other theories that could be true, but are not scientific because they don’t.
