You can see all of 1511's past Chairman's essays & presentations posted here:

They generally went with some sort of theme and tried to discuss more detail & personal stories about important topics that covered impact & partnership.
Some hints
-DONT reiterate what is in your essay... the judges will have read it. You can add more detail to points that are in there, but use this time to say what you didnt have the chance to in the essay.
-Make it personal! Judges love to know how each of the presenters contributed to the impact, or were impacted by the program. Don't spend the whole time on their stories, but add a little personal anecdote here or there.
-Have some sort of theme or take-away message, something that will stick in the judges heads (and try to use this message in the presentation, video & essay in some form).
-DONT bother playing the video. It will suck up all of your presentation time, and the live presenters will be more impressive than a canned film. That said, if you want to embed short video clips in a powerpoint, you can.
- HAVE FUN - this is the most important. If you are having fun while you are presenting, you passion will shine through, and the judges will know how important this is. There is no sense getting stressed, yes you are competing for a big award, but this is just the culmination of all your team does. If they are deserving, it will show, whether or not you stumble on 5 words
