Need help on school project/powerpoint.?

Me and two of my freinds have to go teach the kindergarten cl about the Preamble and article 1 of the constitution using a power point slide show and also have to make brochures.

Also were can i get lil sound clips like the whole election day thing were it gos duh duh da da duh duh duh duh duh. Lol if you dont know what im talking about its fine
