No, because you shouldn't be on Facebook at school. You should be either studying, or hanging out with your friend in real life like a real human being, or getting some exercise on the yard. You can use Facebook at home. If all else fails, go to the library and get a start on your homework. It's blocked for a reason, and although I know how to unblock school computers, I refuse to do it unless it's for something important (like when I needed to download an ebook for a project I had in history a couple of years ago). Facebook is not important, it's just a way for you to cyber-whore yourself to your e-friends on some social network.
