Suggesting Presentation topics.

I have a Presentation with 4 other students. it needs to be from 20 to 40 mintues long. 

I need you to suggest me 2 topics that can eventually help the university of Tulsa in a way that addresses the following craiteria:

-The topics can have several point of views, in a way that makes each student able to work alone indviusually and then we can just add the slides together ( mention thesis statement and supporting details which should be a total of 5 for each topic)

I need you to find at least 4 sources for each topic that I can use for the presentation.

Please keep in mind that we are all engineers but the topic doesn't have to be nessearly about engineering. smplicity is the point behind this.
