You can wink at her, give her compliments, get to know her first. Be her friend and then you can see if she has mutual interest in you.
Talk to her about common interest's. Be yourself.
Try playing 'hard to get' or make her jealous by pretending interest in another girl.

It will be very difficult if the girl's physical appearance is the most important. That would mean that your interest in her is likely shallow and meaningless beyond the desire for an attractive playmate.
It depends on the girl, find out things she likes and show her that you take an interest on them too. But don't lie or act fake. Usually a girl likes a funny guy that can also comfort her and make her feel happy no matter what. Just try to make her feel happy whenever she is with you.
give her compliments, ask to be her partner in class or sit by her or whatever, get to know her and take up in interest in what she likes, and be yourself :)
Find a common interest and make them get to know each other.
Then move on. If the girl has no interest in you then you shouldn't worry about it.
