Science-Related Topics

• In truth, there are very few things in this world that can't be debated (given an audience motivated to contend your statements). As such, look for topics which are grounded in factual statements. These may include scientific findings, which include knowledge derived through logical or noncontested realms. A few science speech topics might include: "Our Solar System" (facts about orbits, planetary sizes and gravity), "The Human Body" (information on different organs and how muscles work) and "Weather Patterns" (facts about the forming of rain and wind patterns).
  
  

History-Related Topics

• While the motives behind certain events in history may be convoluted and debatable, the events themselves are usually noncontroversial. A few such topics might include: "The Bombing of Hiroshima" (discussing the estimated force of impact, the lives lost and the recovery efforts), "The Hindenburg" (noting dimensions, lives lost, location and time) and "The Holocaust" (a recap of affected locations and a discussion of known facts about the facilities).
  
  

How-To

• Regardless of what your speech is explaining, premise it with a statement that yours will only be one of the possible ways to accomplish a task. In this way, you'll avoid controversy over the existence of other, potentially more efficient ways to perform the task. To decide on a topic for this style of speech, take note of things at which you're particularly proficient. A few general topics may include: "How to Play Hide and Seek" (or how to play anything you're passionate about, from board games to cards), "How to Prepare a Banana Cream Pie" (listing ingredients and baking instructions) and "How to Write a Speech" (listing the steps you've taken to write the speech you're giving).
  
  

Informative

• A speech that is strictly informative (such as "All About Cheetas") should draw from highly regarded factual sources. In doing so, you'll reduce the risk of creating controversy over the information you provide. Other topics for informative, noncontroversial speeches may include: "Oak Trees" (describe the life cycle of an oak tree), "The North Pole" (describe the climate and wildlife) and "Gasoline" (describe the production and uses of gasoline).
