What Is an Informative Essay?

An informative essay explains a topic objectively using facts, examples, and evidence. Unlike an argumentative essay, it does not attempt to persuade readers or defend one side of an issue. Instead, its purpose is to educate by presenting accurate, well-organized information.

Informative essays may:

• Explain a process

• Explore a historical event

• Present scientific information

• Examine a social issue

• Clarify how something works

The strongest essays leave readers with a better understanding of the topic.

How to Choose an Informative Essay Topic

Before selecting a topic, consider these questions:

• Is the topic interesting to you and your audience?

• Can you find reliable information?

• Is the topic narrow enough for the assignment?

• Does it allow you to explain rather than argue?

A focused topic is usually easier to research and organize than a broad one.
