An informative speech teaches the audience something: how a process works, what happened at an event, or what a concept means. Unlike a persuasive speech, you are not asking anyone to change their mind. You are trying to leave them understanding your topic better than when you started.
The outline is where that happens. It forces you to choose a few main points, put them in a sensible order and check that every fact has a source. Once it is done, the speaking notes, your note cards, almost write themselves.
The standard informative speech outline format
Most teachers and public speaking courses use the same three-part format. The labels vary slightly, but the parts are the same.
- Introduction An attention getter (a question, a surprising fact, a short story), your thesis (one sentence saying what the audience will learn), a credibility statement (why you are a good person to explain this) and a preview of your main points.
- Body Usually three main points. Each one has two or three sub-points, with examples, evidence or explanations and the source for any fact. A transition links each point to the next.
- Conclusion A summary of the main points, a restatement of the thesis in fresh words and a closing line that leaves the audience with something to remember.
Organise the body in a pattern that suits the topic: in time order for history or a process, by parts for an object or place, by cause and effect for an event, or by topic when the points are simply different aspects of the subject.

Informative speech outline example
Here is a complete outline for a five-minute speech. The facts are general and widely published; in a real speech you would name the source for each one.
Specific purpose: To inform my audience how the International Space Station stays in orbit.
Thesis: The space station stays up because it is always falling towards Earth while moving sideways fast enough to keep missing it.
I. Introduction
A. Attention getter: Right now, a handful of people are living about 400 kilometres above us, and they are falling.
B. Thesis: as above.
C. Credibility: I have followed space missions since primary school and read NASA and ESA material for this speech.
D. Preview: how fast and high it is, why it doesn't fall down, and how it is kept there.
II. Body
A. The station is high and very fast.
1. It orbits roughly 400 km above Earth.
2. It travels at around 28,000 km/h and circles the planet about every 90 minutes.
Transition: "So if gravity still works up there, why doesn't it come down?"
B. It is in constant free fall.
1. Gravity at that height is still most of what we feel on the ground.
2. The station falls towards Earth, but its sideways speed means the ground curves away beneath it.
3. This is why astronauts float: they are falling along with the station.
Transition: "But falling forever isn't quite free."
C. It needs regular boosts.
1. A very thin atmosphere still drags on the station and slowly lowers it.
2. Engines on the station or on visiting spacecraft fire from time to time to raise it again.
III. Conclusion
A. Summary: high and fast, always falling, gently boosted.
B. Restated thesis: The station stays in orbit not by escaping gravity, but by falling around the world.
C. Closing line: "Look up on a clear night. It might be falling past you."
From full-sentence outline to cue cards
Many classes ask for two versions. The preparation outline is written in full sentences with references, so your teacher can see your research and structure. The speaking outline is what you actually use at the front of the room: keywords, short phrases, the exact wording of your opening and closing lines, and any figure you must get right.
- One card per part. Introduction, each main point, and the conclusion each get their own card.
- Write transitions in full. They are the lines speakers most often forget.
- Mark sources with a short tag such as "(NASA)" so you remember to say them.
- Number every card in case you drop them.
Paste your speaking outline into the editor and it splits it into cards for you. Our guide to writing cue cards has more on layout and how much to put on each card.
Timing by speech length
At an average speaking pace of about 130 words per minute, this is roughly how much you can say and how to split the time.
| Length | Words | Intro | Body | Conclusion |
|---|---|---|---|---|
| 3 minutes | about 390 | 20–30 sec | about 2 min | 20 sec |
| 5 minutes | about 650 | 30–45 sec | about 3½ min | 30 sec |
| 7 minutes | about 910 | 45–60 sec | about 5 min | 45 sec |
| 10 minutes | about 1,300 | 1 min | about 8 min | 1 min |

Citing sources out loud
Your written outline carries full references, but the audience cannot see them. Mention the source in a natural way just before the fact: "According to the European Space Agency…" or "In a report published last year, [organisation] found…". Give the organisation or author, and the year when it matters. Two or three spoken citations in a five-minute speech is usually enough to show your research without slowing you down.
Common mistakes
- A topic that is too big. "Space" is a subject; "why the space station doesn't fall" is a speech.
- Persuading by accident. Phrases like "we should" or "you must" belong in a persuasive speech.
- Too many main points. Five points in five minutes leaves no time to explain any of them.
- No transitions. Without them, the audience cannot tell when one point ends and the next begins.
- Writing the whole speech on the cards. Keep the full text in the preparation outline and only prompts on the cards.
- Not rehearsing aloud. Time at least two full run-throughs before the day.
