Hi Ann,
My DD is obsessed with Egyptology too.
Our library has a TON of videos (both kids and adult) for checkout. That is fun, then she can actually see the stuff.
I know that on Google Earth you can view the real Pyramids and Sphinx (blurry but neat).
Also the best books I have found are in the Art section of the Adult Books. We have 2 right now that are amazing. It has so many beautiful pictures of EVERYTHING, in the Egypt section of the library you are going to run into more research books (with wonderful pictures just a lot of writing).
The IMAX in Austin is showing a movie that we will be seeing for her 7th birthday.

It helps that I love Archaeology too, so I can't complain.
Have Fun!
Beth
