Think of an expository essay as an investigation. They are often used in the business world to check the feasibility of an idea. For example, a software company may decide to commission a new piece of software but first have to see if it is going to be possible within the boundaries of their own technology, budget and talent, and within the feasibility study you will often find an expository essay.
Be very wary of picking a topic from the Internet
To start with, if you are looking at the Internet then you are looking at the same thing that millions of other students have looked at. This means there is nothing on there that could be considered original. If you change the topic substantially then it may be considered original, but as a rule be wary of picking topics from the Internet.
Can you make a topic that revolves around a textbook chapter?
It is not the most original idea in the world, and it is quite predictable, but at least you know what sort of research you have to do, and at least you know there are some good sources of research you can reference. Another little perk of writing an essay on the topic that revolves around a textbook chapter is that it also acts as revision. It is easier to remember things you have written essays about.
Do not bore your professor with a tired topic
This is another reason why picking a topic over the Internet is not a great idea. Try to think up an interesting topic that interests you as well as your teacher. If you find the topic interesting then you may do a better job through more thorough research and more concerted effort. Your teacher may also grade you a little higher because teachers are human and an interesting essay beats all those essays that cover the same thing.
The goal of this tip is to remind you that your professor/teacher is human. Your professor’s eyes glaze over and he or she thinks of what he or she could have been when a topic such as “capital punishment”, “911”, “the abortion issue”, “black people‘s rights”, “childhood vaccinations” are topics for your essay. No matter what view you take or opinion you have it is not going to help because your professor has seen it hundreds of times before.
Research first and then pick your topic
If you are really stuck for ideas then do a little research first. You may be surprised at just how much content is out there for certain issues. Browse your research sources until a certain subject jumps out at you. If you find it interesting as you research, then consider it for your essay topic. Again, remember that if you find the topic interesting then you will probably do a better job–or at the very least the writing period will not feel so much like work.
Call back to your topic and thesis as you write
Did you ever see the movie “Freddy vs. Jason?” It was made with stoners in mind because every ten minutes it spells out the plot. Do something similar in your essay, just do not do it so poorly. As you write, you should mention how what you just wrote affects the progression of your thesis (the progression of your investigation).
Be careful when you over-describe
Descriptive language is not a bad thing, but it is more at home in a narrative essay. You may need a fair amount of descriptive language in your expository essay as you describe the subject of your essay, but too much descriptive content may not help you score as highly as you think. Do not burn up too much word count on descriptive language.
How to shorten descriptive language to make your essay more concise
If you are serious about doing the previous tip correctly, then you need to learn how to squash together your descriptive words. Here is an example:
+ The long version
The mutated nut had a brown skin and was the size of a peanut. The skin on the nut feels a little like banana skin.
+ The concise version
The mutated nut was peanut sized with brown skin that had a banana skin texture.
