Presentations

The following table consists of our four powerpoints presented over the course of the project. We worked on the presentations together and split the slides in a way where we each had equal opportunities to discuss our individual efforts on the project. The four presentations include all of the base guidelines given to us in the presentation guidelines along with captivating visuals provided by Riley Cammack and Sawinna Huang.
