Argumentative essay topics are always geared to convince the reader of something. The point for an arguing essay is to: describe, explaining, supporting. Giving examples, proving your point with facts. But while an arguing essay isn't necessarily meant to be a direct argument, how you argue something can still be quite persuasive to the reader
There are several types of argument that you could use in your argumentative essay. You can use either argumentative or descriptive essay. In an explanation essay you will need to give examples to support your point. When giving examples, you can use descriptive words like "a tree", "a dog", "a mountain", etc. Using descriptive words gives the readers a picture or idea of what you're talking about.
If you're presenting a scientific piece of data, you may need to give explanations, replications, etc. For an explanation essay, you'll want to do lots of direct and indirect examples. Giving examples will make the explanation much easier to understand.
You could also do both direct and indirect explanations. Direct explanation involves using science to tell a story. Indirect explanation involves using words to explain things and then make a claim. It is best to stick to only one side of the coin, so as not to confuse the person reading your work. Giving multiple explanations helps when your audience isn't that familiar with your topic.
If you are using a scientific method, it is important to explain the scientific method. You should describe how the process works and why it is relevant to your topic. It is usually best to explain things this way: First, there were a number of fish in this tank. Then, some kind of experiment was done, and now, here are the results.
Sometimes you will have to use a different kind of explanation. A deductive-nomological explanation uses inductive arguments. fMRI explanation deals with how brain function works. An explanation based on science fiction might require a strong strawman argument. Your audience might not be up to understanding a scientific explanation, so it's best to stick to a deductive-nomological explanation.
You don't have to describe every part of how something works, but when you do need to, try to describe each step in a way that doesn't presuppose anything you already know. You can start by showing, point out, or quote something that has already been proven, then show something new that is still being discovered. A good explanation will demonstrate a priori, and it usually has a good predictive value. It may not be able to explain something completely, but it can help in making the rest of the essay simpler and easier to understand.
An explanation is much easier to follow when your audience already knows what the answer is. For example, if you're giving an explanation about the laws of physics, make sure that the audience already knows that there are different laws for light, sound, and quantum mechanics. A simple explanation such as "all animals are fast swimmers" would be better than "all animals are small fish." It makes the rest of the essay much easier to understand.
Explication is not necessary to establish the main point. Even though it's common for people to quote from secondary sources, it's unnecessary to explain everything about the secondary sources. If you don't have enough space to explain everything, just quote the most important things and leave the rest as a side note. It will only confuse the reader and they won't read the entire thing, thus decreasing the effectiveness of your Explicar.
Sometimes your Explicar will explain something important like the difference between a left and right turn in driving. Sometimes your Explicar will explain something simple like how to tie your shoes. As long as you explain something important, you've already done your job. Remember that Explicars are there to help you. They give you help when you're stuck, but they're not required.
Do be careful not to overdo the explanations, however. If you're using more than one Explicar for a paper, it may seem like you're trying to double up on the effort. Instead, only use one Explicar for the main topic and another one or two for additional material. This will make your essay more readable and less confusing.
