Well if you're nervous or don't know her well, just take her for something small like a drink (coffee, whatever), or maybe a meal - this way you'll talk, movies wont be great if you don't know her well cos you can't get to know her. Plus if you take her for a coffee or something (ok not romantic but still) it'll give you a chance to make your excuses and leave if it's not going so well, same with her - you can hardly walk out of a meal. 
Maybe when you get to know her a bit better, figure out what she likes more - if she's a quite active person then ice-skating is nice, if not then movies and a meal - or even cook for her
