Science has a long history of being perpetually wrong. They said all matter was made of earth, wind, fire, and water or something like that because that's what they observed and logic pointed to it and it was somewhat provable. The same goes for the Earth being flat. The same goes for space being made of aether. The same goes for the sun going around the Earth. The same goes for turning lead into gold. The same goes for asbestos being safe. You name it, science was wrong about it but for all given cases, it was widely accepted as correct at the time.
So as long as they preface the scientific curriculum with that, I think they're fine. Then 10 year from now when they disprove the existence of dark matter, they won't feel so bad. Science is just one long history of turning incorrect theories into facts for no reason and then disproving them.
