Dynamic Bulletin Board/Web Scavenger Hunt Idea

I have giant music notes on the hallway walls with trivia information on them (i.e., composer information, faculty musicians, "dynamically" speaking [pp=very soft, etc.]), with the same information on a page on my web site. I ask trivia questions throughout the month, which my students can find the answers to in the hallway on a poster or on my web site. The students place their answers in a box outside my room, and I draw winners.
