145 Informational Essay Topics

By their nature, information essays can be a little dry as they often need to include technical points and established research. Though that doesn’t mean that your informational topic won’t be interesting. The right informational topic is often one that you can engage with, and research thoroughly, to then engage the reader in a way that further elevates their own knowledge base.

Tips for Writing an Informational Essay

Choosing a topic that you are already familiar with, will go a long way toward helping you write a strong informational topic essay. Though you shouldn’t think that just because you are well-versed in one or two topics that you are the definitive source. Putting in the necessary research will go a long way toward helping your present a thorough essay that the reader connects with. You might even find that there is a wealth of information that you were previously not aware of.

Ideally, researching two or three topics that you are keen on within a specific genre or category will go a long way toward helping you find the one that you can present with the most clarity.

Tone & Point of View

When writing an informational essay you want to write from a third-person point of view. This will help you maintain an objective voice during the essay, which will also help engage the reader. This is especially important for topics that might be controversial, where writing in the third person communicates to the reader that you are not writing from personal bias.

As you offer up key facts, make sure to quote the original source directly or include a footnote. Then make sure to include a detailed bibliography that supports your research.

This often starts with finding two or three topics in a similar genre and engaging in some preliminary research. This will help reinforce your knowledge base, while also helping you to make a more informed choice on the topic you want to write about.

Structuring an Informational Essay

An informational essay should use the standard five-paragraph structure. If the assignment has a greater length requirement you can simply expand the number of body paragraphs as needed. This type of structure will give your educational essay a natural flow that makes it easy for the reader to follow.


An informational essay needs to clearly state the topic in the first sentence or two of the introduction. It also needs to include a clearly worded thesis statement that also demonstrates the authority of the information you are about to convey. The closing sentence of two of the introduction should connect directly to the fact that will be offered up in the first body paragraph.

Body Paragraphs

The first body paragraph of your informational essay should connect with the original thesis statement with strong supporting evidence that comes directly from your research. This might include a direct quote from a well-established research study or an authoritative published paper. Ideally, the central theme of your first body paragraph should be your strongest. The last sentence of two should lead to the second supporting body paragraph.

The following two or more body paragraphs need to offer up different, yet support facts that further connect to the original thesis. Here again, each body paragraph needs to include well-documented examples. Each body paragraph should end with a sentence of two that leads into the next body paragraph’s central idea.


Your informational essay’s conclusion should have an authoritative tone while providing a definite answer that reasserts your thesis statement. This might also include a statement that encourages the reader to be more aware of the topic or anticipated research or coming events that will further support your thesis.
