Informational speech topics

 - good informative speech topics by the 100s! 

By: Susan Dugdale | Last modified: 08-05-2023

Informational speech topics ideas are literally everywhere. Anything, and everything, is potentially a good informative speech topic.

For example, look at the device you are reading this on. That smart phone, tablet, or lap top is a possible topic.

So is what you doing now - reading.  How do people read? 

Why do words, specifically ordered arrangements of letters, make sense?

See what I mean? As soon as you start to really think about it topic possibilities bounce out from everything! 

So how do you choose a good one?

Choosing a good informative speech topic

The best way is to select a topic that genuinely interests you and you know will interest your audience.

You'll also want to make sure you can cover comfortably what you've chosen within the time limits you've been given. 

Once you've got your topic, find an aspect of it, or an angle, that's appealing. Next add research, your personal experience, and use visual aids or props to illustrate it, where possible.

Good informative speech topics from Wikipedia

Wikipedia logo with text 'Wikipedia The Free Encyclopedia'

To get the 100s of informational speech topics below I began by visiting Wikipedia's main categories page.

From there I clicked around the thirteen principal headings opening links I found interesting, and then drilled down even further. 

Using these informative speech ideas

I suggest you browse my suggestions and select a few  possibilities for further investigation.   

Please be aware that most are too broad to make a good topic for a speech. You'll want to narrow them down, to find a sub-topic, or even a sub-sub-topic, that's meaningful, and manageable within your speech time constraints. 

How to narrow a broad topic down

For example here is the chain of steps leading me to the subject organic farming. (And that topic is too broad as well and will need further refining.)

The first step was opening Technology and applied sciences on main categories page. From there I opened Agriculture. Then Agriculture by type. And then Organic farming.

Sub-topics arising from Organic farming could easily spark an interesting speech, or they could be further refined even further, to a sub-sub-topic. Here are some sub-topic possibilities:

  • crop rotation
  • companion planting
  • pest management
  • weed control
  • composting
  • animal welfare
  • organic certification
  • health benefits of organic farming
  • the spread of organic farming
  • permaculture ...

And if we narrow down the sub-topic companion planting we get a collection of sub-sub-topics. For instance:

  • pest control with companion planting
  • history of companion planting
  • commonly used companion plants

 What makes an informative speech

Decorative Button: What makes an informational speech?

The key to an informative or informational speech lies in its title.

The word 'informative' means to inform, instruct or enlighten. Inform in this sense does not include giving your opinion.

An informative speech is a balanced factual presentation of the topic uncolored by your personal emotional response or judgement.

For example, if the topic is 'Raising the Drinking Age', what I personally think about it, good, bad or indifferent, is completely irrelevant. The addition of personal bias to an informational speech topic changes it to a persuasive one.

For more see 4 types of informative speech: definition, description, demonstration and explanation. You'll find example outlines, suggestions for topics and the 7 key characteristics of these speeches. It's vital reading if you want to give an effective informative speech.
