Choose a topic that is important to you and that you could pick a side on. In order to be persuasive, the speech must present good evidence, logic regarding the topic, appeal to the audience on an emotional level, and must have a connection to the speaker. Once the topic is chosen, think about what the audience should do with this information. At the end of the speech, what would you ask the audience to do? This requirement is all about advocacy, the ability to pick a side of the topic and advocate for that side. If you want the audience to change something, do something different, or believe something that you believe, then you need to be able to articulate that.
Create an outline based on your ideas and the information you already know, then research to find 3 credible sources to support your claim. Add the new information to your outline to support or clarify your ideas. Ensure you have a strong argument by critically evaluating your main points, the appropriate organizational patterns for a persuasive speech, and the research you have found. You only get one opportunity to persuade the audience that you are correct, you want to make sure your information is strong and compelling.
