Database Lesson Plan

When thinking about my idea for my lesson, I thought, no biggie, I'll whip this out in no time.  NOT!   I have the idea, but when I sat down to start typing up the plan, it became much harder than I expected.  My idea is this....A crime has been committed and I'm thinking of artwork stolen from the Met in NY and the criminal is traveling through the northeast and southeast regions.  Based on the clues in the "criminal report" the students will have to use a database of states to figure out through which states the criminal has traveled.   That's pretty much as far as I've gotten.  I'll be doing this lesson with 5th graders based on their geography curriculum.  I'm kind of stuck on what they should do as part of the "create" section of the SSCC.  I was thinking they fill out a chart or timeline type thing of the states that the criminal traveled through, but then what do I do for the "communicate" part?   I was thinking of a wanted poster, but then that doesn't really fit.  I'll have to keep thinking on this one. :)
