Hi Piper's Mom,
A few suggestions that come to mind...
I recently discovered that some public library systems have amazing web based resources at the disposal of its patrons. Our system, for instance, has "Mango Languages" which is has web based foreign language courses. I never realized what was available because I always went straight to the web catalog. You might consider checking with your library to see what resources are available from home.
Are you on netflix or a similar streaming system? That would provide easy access to a variety of documentaries as well.
Finally...there are a lot of good web based simulations, often associated with museums. Visit websites of science museums, art museums and childrens' museums and see what you find. While these won't provide adequate depth, they could provide an opportunity to topic search until she finds something that should wants to dive into in more depth.
Best of luck
