Many of us have wondered since our childhood about the color of the sky.

Choose this as a topic for your informative speech and give others the ability to answer when their children ask them this question.
- Black holes: Concentrations of mass that can suck in the light.

- 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.

- 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.
- 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.

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.

Learn more about the mechanism of the epigenome, and deliver an informative speech on this exciting subject to your audience.
