Anything you see can become the source for your next informational speech. For example, consider looking into your favorite animal. Research basic facts about it to include in your speech. Try to also present interesting facts that most people do not know. As another informative speech idea, inform the audience about a musical instrument that interests you. Include the history of the instrument and where people use it today.
Monumental events have occurred throughout history. Take an event that many people have heard about and expound on it for your informational speech. This event could have taken place once in history (e.g., Pearl Harbor) or reoccur regularly (e.g., the Olympics). You could also take a different route and choose a personal event in your life. If you have a club meeting you attend or an annual church function, inform your audience about it.
A speech on a concept can range in topic from religion to intangible fears. A speech on religion does not have to inform the audience about your religion; you may want to choose a religion that you do not know much about. Then you can spend time researching and learning, and give your audience an unbiased, factual view. As another idea, present your audience with information regarding an interesting phobia.
Magnificent places fill the globe. Choose a country and learn its history and culture. Then present this information to the audience. You can include details about what types of food are eaten and clothing worn. Alternatively, you could make the view more narrow by choosing a specific landmark, such as the Eiffel Tower. Present compelling facts to your audience about the landmark you choose and the history behind its construction.
