In-School Scavenger Hunt…HELP!!!?

So we’re having a class lock-in at the school, and we would like to do a SCAVENGER HUNT. Not so much finding objects, just reading riddles/clues and moving them from location to location. We’re starting in the lobby and would like to utilize many rooms/areas of the school. So far we have the library, choir room, and concession area. For sure we would like to use the science room, math room, fieldhouse/gym, auditorium, and agriculture room. If you have any ideas for clues or riddles to help move them to those locations, it would be greatly appreciated. Thank you a lot!
