You begin with your introduction. After spending a reasonable amount of time thinking over the topic, you can introduce it by placing your argument either in favor or against, as essay writer has decided. Note down all you can about the topic. This would be your sample essay. To back your statement, you now have to produce substantial data from sources which would be relevant to your topic. Every attempt you make at proving a point, it would have to be substantiated with solid evidence. This is the essence of your research essay.
Care has to be taken to revolve your arguments around points which link to each other throughout the essay. As you move on with presenting your point of view, it becomes important not to loose track of maintaining a flow in your essay. With the use of simple language, you can always include good research material which would fit in. Try and find research material that is correct and would need minimum referencing by a reader. Even though this would be a description essay, maximum stress would be laid on gathering authentic data.
