If you're interested in culture, you could look at questions of German responses to the war. There's a very extensive scholarly literature on postwar German art, some of which deals with German responses to the war(Gerhard Richter and the exhibition Homage to Lidice would be a good thing to look at; if you want other options the book Art of the Two Germanys: Cold War Culture is a good place to start) and also a very large body of literature on postwar German film, especially the genre of "Rubble film", to draw on.

Well, I allways find society-related things more interesting than political topics. How "close" to WW2 has your subject to be? Things I would enjoy reading as a German who is very interested in history, so most of the "usual" and "overdone" things are pretty common to me:

How did the view on children and education change from pre-war HJ and BDM-style (making boys into suitable soldiers later, training girls to be good arian breeding machines) in post-war germany? How was childrens education different between the GDR and West germany? How did society react to the loss of men? How was the situation for captured people who came back to germany either shortly after the war or as late as in the 1950s? How did society's view on women change from the Nazi's bloind haired breeding machines to modrn german women? (How did the two germanys compare?) How did society's view on men changed from the Nazi's strong arian soldier ideal to modern german men? (How did the two germanys compare)

I would really like to read your finished report!

If you're an american like me, you might have a ton of luck looking into the chinese theater of operations - I don't know if it got even a passing mention in my high school classes.

Alternately, you could look into he repatriation of japenese after the war (soldiers and civillians were scattered throughout the Pacific and needed to get home)
