This is the reason why we are behind the rest of the world in science and mathmatics. Obviously, science and mathematics are important. Who builds our defense system? Who creates our highways and bridges? Engineers using science and mathematics. Not to mention Doctors and Biologists who work constantly to find cures for some of the most deadly diseases. These kids don't know their potential. Most people don't know their true potential until age 17 or 18. Maybe later. We need to provide a way for kids to expand their minds and explore areas that they have never heard of.
Evolution is really the only thing that religious people have a problem with. I don't think hearing a scientific theory will turn them away from God.
