Should I message this girl that I have seen looking at me a lot on Facebook?

So there is this girl at school (high school) that I have recently noticed glancing at me a lot, flipping her hair, acting nervous around me and always looking away when I look up. So I think she might like me and I was wondering if it would be a good idea to message her on Facebook. I don't know her very well, but we have been going to the same school since 6th grade. We just got onto vacation for two weeks, so should I message her on Facebook or wait to do something at school when we get back. Also if I do message her on Facebook what should I say. We are both sophomores in high school.

Talk to her in person.

Message her on Facebook and just be friendly and start with a "hi" then "how are you?" just be friendly and kind to her. It seems that she likes you.
