Here's a radical thought: don't use a presentation deck! Hand out a collection of images, printed or via pdf file, give the student a couple of minutes to quickly become familiar with it, then just talk about each of the major figure in the handout. This was my solution to 'powerpoint hell' when sharing results in grad school, I don't know if it really applies to your case (non-expert students), but it may be worth a shot. Hell, its better than reading off slides! Good luck!
