My main advice here is that you need to tailor this to the individual child. What will turn one kid on to free computing, will cause another to think of Linux forever after as "that annoying thing which I was forced to use, when I didn't have a choice in the matter", and that's probably the opposite of what you want; it will associate "Linux" in their mind with not having a choice. What is this 8-year old girl interested in?
