Presenting a language?

Alright, some of you may know that I'm doing Ajuk as a project at
school, and part of the process is that we have to present our projects
to the class in a presentation of ten minutes or less.

Does anyone have any ideas of how to present a language? We must assume
that the people have no knowledge of linguistics or any foreign language
besides a minimal amount of French, at best.

Thanks in a advance!
