Default How An Overhead Projector Works?

So this is the topic my 1st grader choose. Yes, I thought it would be easy to find easy-to-understand info on this topic, but so far three reference librarians have not been able to find anything age-appropriate and my website searching has been pretty futile. Anyone have anything they can pass along? THanks for your help.
