This is a final project I do with my freshmen, discussing art history and two of the biggest art thefts known--the stealing of art during WWII and the Isabella Gardner Museum Heist (which is still an open case.) Students find it quite interesting, and it makes for a very good final project or even mid-term type project.
I allot a fair amount of time with this, since I do usually do this as a final. Most of the work should be done at home, to start. However, as the due date gets closer, I set aside dates so students can work in class.
