I know it isn't a Christian curriculum, but has anyone used Real Science 4 kids? I know it doesn't have a creationist point of view (which I of course, DO want) but is that something I could add to it? I am really stumped as to what to get for science (1st grade) because I want something interactive, fun, yet advanced because we really love science. I would prefer to have some kind of book or worksheets to go along with it, not just primarily online. THanks for any help you can give!
