How about a mineral and gemstone collecting kit? You could include a book or chart to help identify different types of minerals and gems, a small magnifying glass, and some materials for collecting samples such as a rock hammer and a collection bag. Another idea would be to get her a subscription to a mineral and gemstone magazine or a membership to a local mineral and gemstone club where she can meet and learn from others who share her interests.
Or you can get her a star map with the date when she was born.
