Very short notes, even single words, can be your roadmap for your entire presentation. Get excited, move around and vary your tone, even if it feels more dramatic than you would do in normal conversation. Add pauses when emphasizing key points or when showing visuals so the audience has time to absorb the information before you continue. Be careful of distracting movements, such as swaying back and forth or tapping hands on the podium. Be careful about using humor.
Nothing relaxes an audience like humor, and nothing kills a presentation like a bad joke.
Try speaking out loud, into a tape recorder, or in front of friends or family. Visuals and props should also be clearly marked and colorful if possible. When introducing visuals be sure to verbally highlight the main points and draw conclusions. Keep your body and attention directed toward the audience when discussing the visual. Remove the visual when you are finished using it to ensure the audience's attention is back on you and what you are saying.
