🔥 Mind-Blowing Informative Speech Topics for College

Here are some more wonderful speech topics for you. To better help you understand what your informative speeches should be about, we also provide a short description of the subject. Let’s go!

51. Why is the sky blue? The mechanism of refraction.
    Many of us have 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. Choose this as a topic for your informative speech and give others the ability to answer when their children ask them this question.
52. 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. Their density is so high that their gravity is immense; even light cannot escape such gravity once it gets under the event horizon. If you want to prepare for an informative speaking event, you can choose this as your topic to impress your audience.
53. The deepest depths: The Mariana Trench.
    The Mariana Trench is known to be the deepest place underwater on Earth. Its depth reaches almost 11 kilometers (nearly 36,000 feet) at specific points. However, the underwater surface of the trench also has its landscape; it is known that there are mountains in it. Find out more about these unimaginable depths and prepare an impressive and fascinating speech for your audience.
54. The “dangers” of dihydrogen monoxide: A hoax for the scientifically illiterate.
    In the 1980s, a hoax was published by a newspaper on 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.
55. 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. However, the choice should depend on the nature of your inquiry, and sometimes even on how much is already known about the subject. Make an excellent informative speech on this topic and help your group mates with their next research project.
56. The history of data storage devices.
    Computers are virtually ubiquitous nowadays, and data storage devices are used both inside computers (e.g., hard drives) and outside them (DVDs, flash memory, data storage arrays). Preparing and delivering an exciting and informative speech on this topic can cause your audience to enjoy themselves truly.
57. Brown dwarfs: “stars that didn’t quite make it.”
    Brown dwarfs are substellar objects with a mass that falls in the range between 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.
58. The invention of photography.
    Making photos is one of the most popular hobbies today now that we have digital cameras. In the past, however, photo cameras used film to take pictures, and even before then, there have not been any cameras around. The invention of photography became a crucial point in the history of humanity.
59. The mysteries of the Indian caste system.
    The Indian caste system is one of the most ancient traditions in India. While the caste system means formalized inequality, this idea has interesting religious and cultural roots. Your audience will enjoy an informative speech on this topic about the cultural tradition of a foreign country.
60. Cannabis and the history of the word “assassin.”
    Did you know that the word “assassin” is derived from the word “hashish”? Hashish was a drug popular in a medieval Islamic sect known as Nizari Ismailis. Its members are reputed to have been well-trained killers performing surgical strikes at their opponents.
61. 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 DNA needs to be used when a cell is created. Learn more about the mechanism of the epigenome, and deliver an informative speech on this exciting subject to your audience.
62. “Shining magic powder”: the Goiânia accident.
    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. Having thought that the dust was precious and probably magical, the businessman took the powder to his home to show it to his family and friends. However, the fairy tale soon turned into a deadly nightmare. Find out more about the accident, and make an informative speech for your audience to tell them about why glowing “magical” powders are probably very dangerous.
63. The invention of the first clock.
    All sorts of clocks and watches are an indispensable part of modern life. However, before the first clock was invented, people could not tell the time precisely and had to rely on things such as the Sun, stars, and mechanisms such as sundials to tell the time approximately. Tell your audience about the history of the brilliant invention in an informative speech on this exciting subject.
64. The phenomenon of male bisexuality in the culture of Ancient Greece.
    In Ancient Greece, it was believed that a middle-aged man should find a young man and serve as a mentor for him, also engaging in sexual contact with him. However, that older man still needed to have a wife and children. Tell your audience more about this exciting tradition in an informative speech on this topic.
65. Does “real-life” water freeze at 0°C (32°F)? The freezing point depression.
    Today, virtually everyone knows that water freezes at 0°C (32°F). However, this is only true of pure water in certain conditions. Few people know that water freezing temperature depends on factors such as pressure and, importantly, the number of particles of substances dissolved in water.

🎤 Informative Speech Examples for College Students

If you are still in doubt about how the informative speech should look, we have helpful examples and famous speech samples that can come in handy!

Example of Informative Speech about Global Warming

Welcome, everyone,

Today, let’s talk about something that we are all responsible for — global warming. And it is not an abstract concept but a global phenomenon occurring ever so slowly, even at this moment. Over the past century, the average temperatures have increased by just over one degree. This may not appear to be much, but many experts agree that the Earth’s temperatures are beginning to rise more rapidly. But what causes global warming?

Global warming happens when greenhouse gases trap heat inside the Earth’s atmosphere. Consider what occurs when you open your car door after you have rolled up your windows on a hot day. The sun’s heat enters the car but cannot escape due to its frame. This is, to some extent, an illustration of what happens during global warming.

Global warming has detrimental effects on our planet. It is not just about extreme weather events. It is about issues that threaten the delicate balance of life on Earth. The rising sea level, driven by melting polar ice caps, inundates coastal regions, causing widespread flooding and damaging coral reefs, the very foundation of marine ecosystems. Air quality deteriorates, and seawater acidity increases, impacting marine life and disrupting the food chain.

Global warming, caused by greenhouse gas emissions, is not a distant threat but an impending catastrophe the consequences of which will escalate dramatically in the near future. The time to act is now. Individual actions to reduce energy consumption, using fuel-efficient vehicles and electronics, can make a significant difference. These efforts, coupled with collective action, will not only restrain greenhouse gas emissions but also improve air quality.

It is not enough to rely on global policies. Individual contributions are also crucial for preventing irreversible damage. Let us seize the moment, take action, and secure a brighter future for the generations to come.

Thank you for your attention.
