Since you mention the word '
slide' I assume you will be making a PowerPoint presentation, the strongest non-chemical narcotic in existence. So without saying anything about content this is my recommendation for keeping the audience awake:
- DO NOT have slides of bullet points which you both show AND read out to your audience three times more slowly than can be read from the screen or they won't be an audience for long.
- DO be knowledgeable about the subject and talk about it, don't just read from a prepared script, although a handful of discussion points and topic reminders for yourself is no bad thing.
- DO have slides which illustrate, even loosely, points or aspect you're speaking about, and...
- DO keep them going through in a fairly brisk manner. (you can always return to one that someone wants to talk about).
I've endured lots of PP presentations and only one was worth the effort of staying awake and engaged.
