Several years ago I develop a scavenger hunt of sorts for the docents.
This was not used by the general public but the volunteers had a ball with
it.  Two pages front and back were filled with silly questions on obscure
bits of trivia that actually had little "educational" value, such as:

What is the number on the drivers license on exhibit in the Hall of
History?

What is the man with the red cap holding in his hand (in the picture next
to the cave entrance)?

How many vertebrae are in the tail of Teleoceras?  I discovered this was
not a good question as they differed as to where the tail began.

Is the pair of hands demonstrating flint knapping, left or right handed?

You get the idea.  It was amazing how much I discovered while putting it
together.
