Just did mine. Comes down to personal style and preference. If you're not an experienced presenter I'd strongly recommend presenting as if you're giving a conference paper, i.e. reading. Practice practice practice until it sounds natural, is well-paced and polished. I practiced in the hall where we were to give the presentation, to get a sense of the room, make sure IT worked, and take Qs from the floor (other presenters).
PPT is useful - good to have slides, but I'd personally avoid loads of text. Keep to 4-5 slides max with graphic prompts, titles/sub-titles, and perhaps a short thesis structure/timeline.
This is what I did anyway and it worked for me but YMMV. Key is practice. Good luck, it's a fun experience.
