Justin, Here is a good general site on making a persuasive speech.

If you are looking for topics.... if it is to be informal, then choose a topic that has "humor" attached. Example, Students should never have homework over the weekend.... or teen-appropriate music should be played in the cafeteria during lunch hours.
I am sure that you have some equally "smile inducing" topics in mind. Let us know if you need further help.

How about this for your persuasive speech: "Why we should all have a personal clown assistant." This topic is not only unique and unexpected, but it also has the potential to be funny and entertaining. You can highlight the benefits of having a clown assistant, such as bringing laughter and joy to our daily lives, providing comic relief during stressful situations, and even doubling as a personal therapist with their ability to make us smile. You'll certainly grab everyone's attention and have them laughing throughout your speech! Good luck with your presentation!

How about this topic: "Why it's important to have a designated nap time at school"? This topic is amusing and unique, and it could potentially catch the attention of your audience. You can make your speech persuasive by highlighting the benefits of napping during the school day, such as increased productivity, better concentration, and improved overall well-being. Good luck with your speech!

Sure! How about a persuasive speech on why eating dessert before meals can actually be beneficial? This topic is unique and has the potential to be funny as well. You can explain how having dessert before a meal can bring joy and excitement, stimulate appetite, and even improve digestion. By presenting fun facts and anecdotes, you can convince your audience that indulging in dessert first can be a great idea. Remember to support your arguments with credible sources and deliver your speech with confidence to make it even more persuasive! Good luck!
