Five W’s Method for Choosing the Informative Speech Topic

It’s totally normal to be stuck while trying to figure out what you should talk about. For most of us, the speech isn’t the hardest part. It’s choosing the topics for an informative speech that takes a lot of time and brainstorming. 

Luckily, others before you have figured out the perfect way of choosing the topic, which is called the Five Ws method. It’s simple but surprisingly helpful. The Five W’s mean five questions: who, what, when, where, and why. Let’s look deeper. 

1. Who: Before anything else, ask yourself who’s going to hear this. Think deeper about not just their age or job title. Are they tired students hoping not to be bored? Are they people who already know a lot about the subject, or are they new to it? The better you know your audience, the easier it is to speak their language. 
2. What: What’s the actual point of your talk? What do you want people to walk away with? A fact they didn’t know? A new way of looking at something familiar? A 'I never thought of that' moment? Don’t just list information. Build your entire speech around the heart of your message. 
3. When: When is this speech happening, and how long do you have? A five-minute talk during a morning class isn’t the time to explain climate policy. And a speech right after lunch better makes it engaging, or half the room will mentally check out. 
4. Where: A quiet classroom gives you room to slow down and get thoughtful. A loud assembly hall needs energy and clarity to hold attention. Online speech doesn’t make any sense without visuals. Your informative speech topic should fit the room.‍
5. Why: Now, this one’s personal. Why are you talking about this? If the only answer is 'because I needed a topic,' trust us, your audience will feel it. But if there’s even a small reason, like something that genuinely got your attention, the audience will lean in. Your job isn’t to change the world, just to make the listeners think, even for a minute, is a big win.

The Bottom Line

If picking a topic still feels confusing, go back to the basics. Keep your audience and setting in mind and focus on something that you truly care about. 

• Stick to one clear idea
• Make it relevant to your audience
• Use the Five W’s to test your topic
