Be sure to have inflection in your voice. Your goal is to engage your audience, not put them to sleep. Be animated about your topic. Talk about it as if it was the most interesting thing in the world. Your classmates will thank you for it.
• Inflection is the kind of movement that radio DJs put into their voice; it's the ramped-up pitch in your voice when it gets excited. You don't want to sound like you've just seen a lion, but you also don't want to sound like you've just seen a squirrel, either. Vary it up to make the presentation more interesting.
