Have you looked into having her create a 'notebook' or 'nature journal' Charlotte-Mason style?
My DC love to do this. I bought them nice drawing paper, nice colored pencils, a few three ring binders, and a hole punch.
Whenever something really catches their interest, like say a close encounter with a bird, or learning about Pocahontas, or lightening-- they will draw a picture of it and write about it briefly, and then use the paper punch and put it in the binder.
The binders have some pretty neat things in them.
I try to have them set one up for general things they study (storms, butterflies, etc) and another separate one for history related things, so they can kind of put those in chronological order. If they write about themselves, I encourage them to put them into the 'end' of the history one, in our 'present time.'
This has worked really well for them. I just suggest, "Wow- that was so neat! Maybe you could make a page about it sometime." and their eyes light up and they start planning it.
