cschnee Posted November 6, 2010 Share Posted November 6, 2010 If you go to the website, http://www.lhsgems.org/gemsguidestopic.html, you'll see orientation videos for many of the book. These give a good idea of the activities within. There is also a free pdf of the book, Vitamin C testing. We've done that one, it's great!
