We haven’t found any science magazines, sadly. There’s too much atheistic content. I don’t mind discussions of evolution, etc., but in some of these magazines, we’ve actually seen articles explaining why God can’t exist. After a while, we gave up trying.
My son is almost 17 now. He likes http://www.sciencedaily.com. He says there are lots of articles on evolution and the like, but he hasn’t noticed any atheistic content. However, if you prefer reading only from a young earth, literal seven day creation perspective, this site would not work for you. Jared also reads a lot of Wikipedia articles.
Sorry I can’t be of more help.
