Three Modes of Delivery
During any presentation, there can be up to 3 methods of delivering content. 
Through your:
- Voice
- Visuals
- Handouts
Most of the information that you convey should come from you (your voice). You are your own best visual aid. You can make the audience connect with what you are saying.
Visuals are great for emphasizing or highlighting certain points, but you never want your visuals to overtake your presentation or distract your audience.
Handouts are a good way for providing your audience with information that would be hard to decipher from a slideshow (detailed charts, graphs, etc.). Handouts also give your audience a physical takeaway they can refer to later.

Know your Audience
In order to understand and fulfill the mission of your presentation, you need to research your audience. You need to determine your audience's level of experience in your subject and you need to determine what their expectations are for your presentation.
Once you have a good grasp of your audience, you can decide what to include or leave out of your presentation.
Preparing a Mission Statement & Goals
1. Before you start planning your presentation, it is important that you determine why you are giving your presentation. What is the mission? What are you trying to get your audience to do?
2. After you've developed your mission statement, you should set goals for accomplishing that mission statement. Your goals are concrete steps that you will take during your presentation.
Example Mission Statement: "To raise awareness about climate change, its causes and effects, and incite the audience to take action."
Example Goals: Provide history of climate change, show charts illustrating increasing CO2 emissions, show video of environmental effects, and offer solutions for curbing C02 emissions.
