Using interrogatives in titles
I have to write an essay in German, and I would like to know how to use interrogatives in a title. Such as "Why I want to travel to Germany" "What I want to do in Germany". Would it be acceptable to say "Warum ich nach Deutschland gehen will.", or "Was ich in Deutschland machen will.", as a title? Or is there a certain way I can say this? In other words, I would like to know how to use interrogatives in a statement sentence. I hope this is clear enough. Thanks in advance!
