Every conversation or discussion that includes people, places, events or processes, is an example of providing informative speech topics for college students. For example, You are explaining to your friend how a particular device is helpful for you or a professor explains the concept. It can be based on anything technology and science, business, management, a general discussion of political views, health and awareness, many more. But it is different from a persuasive speech where the listeners are encouraged to take the action and not just inhale the information. You can easily identify which one it is.
