Microphone at the speech podium

Sometimes, searching for informative topics can give you a lot of trouble.

However, when a team of professionals offers you a list of topics, you know that you can count on each of the informative speaking topics in the list being a real gem.

So, let’s not waste any time – let’s dive into the pool of fantastic ideas for informative speech writing!


Informative speaking: Definition

First of all, keep in mind that you’ll always need to know the answer to the question, “What is informative speaking?” - because this is not just a speech on any topic.

An informative speech is a short presentation of a lesser-known issue and its explanation/description/demonstration.

In other words, an informative speech makes the audience know a topic better. It includes interesting details, facts, and recent research. Informative speeches aren't supposed to convince the audience. They only share knowledge to make a topic more understandable to the listeners.

The primary skill involved here is knowing how to choose informative speech topics that are not persuasiave.


Differences between informative and persuasive speaking

So what is the difference between informative and persuasive speech topics?

While the former gives information without uncovering the speaker's opinion, the latter seeks to convince and persuade.

Generally speaking, any topic about facts, events, trends, concepts, and so on can be made into an informative speech. The better a topic matches the idea of being informative, the more freedom you’ll have while writing your informative speech.


How to choose between a persuasive and informative speech

The main point is: what is your attitude to the topic?

If you can't hold back your emotion while speaking about ecological problems, then stop. Maybe this topic is a bad choice for your informative speech. But it would be the perfect issue to discuss while persuading the audience. By the way, you can find some excellent persuasive essay ideas on our blog.

When writing an informative speech, you shouldn't draw any moral, emotional, or political conclusions. Let the audience make their own decisions about the information they have heard. In fact, this is an essential feature of this type of work.

Now that you know the answer to “What is an informative speech?”, let’s see some great ideas for an informative speech and find dozens of informative speech topics for college students!

    Many of us wondered since our childhood about the color of the sky. Today, most of us can probably say that the sky is blue due to refraction, but very few can explain the mechanism of this process.

Black hole in the space

  1. Black holes: concentrations of mass that can suck in the light
    Black holes are some of the most interesting cosmic objects that are known today. They are massive concentrations of matter in a relatively small space.

  2. The deepest depths: The Mariana Trench
    The Mariana Trench is known to be the deepest place underwater on the Earth. Its depth reaches almost 11 kilometers (nearly 36,000 feet) at specific points.

Find out more about these unimaginable depths and prepare an impressive and fascinating speech for your audience.
  3. The “dangers” of dihydrogen monoxide: a hoax for the scientifically illiterate
    In the 1980s, a hoax was published by a newspaper on the April Fool’s day, reporting the presence of "dihydrogen oxide" in the waters of a city. Later, in 1989-1990, the hoax was published on the Web; the name has been changed to "dihydrogen monoxide" to make it sound even scarier. Find out if your audience is as gullible as the people who organized campaigns to ban the chemical, or just make an informative speech to enlighten the naive ones.
  4. Qualitative versus quantitative: what type of research method to choose?
    When planning a study, you may not know what type of methodology to choose: qualitative or quantitative.

  2. Brown dwarfs: “stars that didn’t quite make it”
    Brown dwarfs are substellar objects that have the mass which falls in the range between that of the smallest stars and the enormous gas giants. They are, however, much more massive than gas giants due to their higher density. However, their mass is not enough to sustain the nuclear reaction of hydrogen into helium fusion; one might say that the most massive brown dwarfs only "barely" lack the mass to become the lightest stars. Selecting this as a topic for your informative speaking will help both you and your audience to learn more.
  3. The invention of photography

  2. Epigenome and its role in gene expression
    Nowadays, virtually everyone knows that genes carry hereditary information from parents to children, and provide the data for the creation of almost all molecules, cells, and tissues in living organisms. However, much fewer people are aware of the mechanism that allows for the formation of different cells and tissues for various purposes, for not all the information from a DNA needs to be used when a cell is created.

    In 1987, in the city of Goiânia in Brazil, a local businessman, the owner of a scrapyard, found a capsule with a mysterious powder that glowed with a thick blue light.

Few know that these planets have no hard surface, and only consist of gas that becomes denser and denser when moving deeper into the earth until the planet's core is reached. This motion would be accompanied in the changes in the surroundings of a hypothetical explorer, such as strong winds, lightning, the level of illumination varying from complete darkness to the brilliant luminosity of the deeper layers of the planet.
  2. Kant versus Einstein: the concepts of space and time from Critique of Pure Reason disproven
    In this monumental work describing the manner in which the human mind works, Critique of Pure Reason, Immanuel Kant proposed a theory that space and time are the inner structures of human consciousness that serve as the "frame" which allows for the existence of perceptions themselves. However, Einstein's theory of relativity disproved this hypothesis, showing that space and time are not non-changing and homogenous.

Marie Antoinette portrait

  1. “If they don’t have bread, let them eat cake”: no smoke without fire
    This phrase is commonly attributed to Marie Antoinette, the last French queen before the occurrence of the French revolution. Although it is now stated that the word is misattributed. There is no formal record of the queen saying that. The very fact that this phrase was plausibly attributed to the queen probably means that the rulers of pre-revolutionary France knew (or cared) very little about the conditions in which their citizens lived. Discuss this exciting subject in an informative speech delivered to your audience.
  2. Prions: the dangers of the proteins
    Prions are infectious agents that cause dangerous diseases usually related to mental health. However, prions are just proteins and not living organisms. How do they produce disease? Tell your listeners more about this topic in an exciting and informative speech.
  3. What are the reasons for human laziness?
    Laziness is probably something that many humans suffer from (or at least claim to). However, not many people know what causes it. Find out more about it and write an informative speech on this topic.
  4. The broad political spectrum: are there only liberals and conservatives? Nowadays, in the U.S., as well as in many other countries, one can often hear that concerning political views, people are either liberal or conservative. However, this is a tremendous simplification. Discover more about this exciting subject and tell your friends and classmates about it by preparing a suitable informative speech.

    Children with disabilities are significantly disadvantaged in comparison to other children. They cannot learn the same skills as other children at the same rate.

  3. Battling childhood obesity: the diet of children must be improved
    Nowadays, childhood obesity is one of the significant health problems in the U.S. One of the primary reasons for this is that the children's diet is far from perfect. This is especially true for more impoverished families, who cannot afford high-quality food for their kids. Make an excellent persuasive speech and tell why the government should support the improvement of the diet for such children.
  4. Living in stone jungles: large cities must have larger green zones and fewer skyscrapers
    Today, it is quite common to build many skyscrapers and other large buildings in centers of large cities.
