I was given a set of health books that we aren't using, and I'd love to give them to someone who might get some use out of them.  They are in nearly brand-new condition, as far as I can tell.  They are the Harcourt Brace "Your Health" series. This appears to be a companion website that might give you some idea of what the series is all about- http://www.harcourtschool.com/menus/your_health.html
Included are textbooks 1-5, along with matching activity books for 1-4.  I thumbed through the activity books and didn't see any markings. Reply here if you are interested!
