Well, she's not quite eight so she changes her mind frequently, although archaeology has always been a big draw to her, probably because of my (purely amateur) involvement in it. So she's been dragged along to digs which she discovered were actually a lot more fun than she expected even when you don't uncover a Saxon hoard or Neolithic burial. Some of my friends and acquaintances are also fairly well-known "TV archaeologists" which has given her a (false) sense of 'glamour' about the subject!
She definitely wants to go into science rather than art, however.
