Brainstorm Your Ideas

Do Your Research

Essays rely on information, not opinions. Now, the next thing you need to do is conduct research. 

Why?
Well, because essays rely on information and not opinions. Moreover, use credible sources to gather facts, statistics, and relevant examples.

Using information from credible sources is important, especially if you ar writing on a controversial or debatable topic.

For that, it’s best to refer to fact-checking websites, such as:

  1. Fullfact.org

  2. FactCheck.org

  3. CSI Library

  4. PolitiFact

  5. Snopes

If you use a personal blog as a source, then first make sure to check if the writer has any agenda. In addition, if you are using a newspaper’s story, then consider WHY they have reported this story.

Create an Outline

It’s easy to ramble or go off-topic when writing an expository essay. Therefore, outlining plays an important part in your essays. It helps readers navigate through the content, working as a roadmap. Furthermore, it even allows you to track progress. 

Pro tip:

Keep your thesis statement in mind when making an outline for your essay. In addition, it helps you to add relevant subtopics and sufficient information to fill each heading and subheading.

Edit and Proofread

Once you are done, you need to edit and proofread the essay to ensure that your work is from punctuation to grammar, sentence structure, syntax, etc. Furthermore, maintain clarity so that the readers can understand what you are talking about. 

Sample

Nowadays, teens are spending hours scrolling through the apps. Well, with this, there is a growing concern about the effects of social media on mental health. 

Studies reveal increasing rates of anxiety, depression, and poor self-esteem. According to a study, teens spending more than 3 hours a day on social media report higher levels of stress.
