The scientific essay is the final part of a scientific investigation, that is, there is no one without the other. If you do not investigate, you can not write a scientific essay, that you have to be very clear about that.

When you write an essay, it is important that all the time you are clear about its purpose in your mind. You must always keep in your mind the central theme, its details, the hypothesis or assumption of your essay and what are the data or arguments by which you guarantee the validity of this hypothesis.

If you forget your assumption, you run the risk of writing arguments or statements contrary to it, which could be very counterproductive.

When you write a scientific essay, you should know that it is very different from when you write an essay for your philosophy or literature classes, whereas what you seek to raise and sustain is not a personal opinion, but to verify an affirmation that arises from the investigation by means of arguments. empirical also arising from research or experimentation.

The four golden rules

Every scientific essay starts from an investigation, all research arises from a question, every question seeks an answer and every scientific answer requires empirical data to validate it, therefore, follow these four rules and you will be on the right track:

  • Identify your topic and the specific research question about it.
  • Plan your answer, which becomes your assumption or hypothesis
  • Research or experiment to verify the veracity or validity of your hypothesis.
  • Transform the results of your research into arguments and write your scientific essay.

The first step: plan your scientific essay

Any text, for it to be right, must be planned before starting, for it is worthwhile that on a sheet of paper or on a Word page you identify in writing the parts of your essay and what goes on in each part. Introduction, development and conclusion.

The planning phase, which follows from research and precedes writing, is the strategic phase in which it is decided how to order the information that has been obtained in a way that is clear, consistent and ensures that the hypothesis is correctly validated. The arguments.

The structure of the scientific test

As we discussed above, the essay has three essential parts:


Here the subject or object of study is raised, the question from which the research is derived (this question seeks an innovative answer, therefore it is a question never raised before that seeks a response never before sought) and the hypothesis or assumption, which it is an interim answer to the question and it will be validated or complemented with the investigation.


Arguments are presented that validate the hypothesis, are developed and analyzed.

In this part, the presentation of the data derived from the investigation and that serve to answer the initial question, are discussed and ordered in a way that allows answering the best way to that question and, in addition, so that they complement in the most The assumption or initial hypothesis is clear.

Then, all the arguments (data, figures, results) are ordered in order to validate the hypothesis.


As a synthesis, the way in which the assumption is validated through the empirical data presented as arguments is highlighted.

There are certain basic instructions that can help you write your scientific essay correctly:

The title of your scientific essay should be a gateway that helps to clearly identify the subject and the main conclusions of the essay, for example: The consumption of social networks during the baccalaureate classes. The struggle between learning time and fun time.

The essay is written in continuous prose and not as a list of ideas or notes (this only applies to the previous planning phase).

It is important that you accompany it with diagrams, tables or graphs if they help to present in a synthetic and clear way figures or data that validate your hypothesis.

How scientific trials are valued

An extraordinary essay

The parts of the essay are clearly defined, but they are perfectly integrated.

It reflects in detail the domain and understanding of the subject of study it deals with.

It has no spelling or typing errors.

The order of each part and the relationship between the parties is perfectly achieved and the clarity is exceptional.

It contains enough empirical information to validate the hypothesis, which is clearly established.

The conclusion allows to clearly observe the relevance of the arguments and the validity of the hypothesis. It is a kind of brief recapitulation in which the reader is reminded of the subject and the assumption and how these have been appropriately validated with the argument.

A good trial

It reflects that there is sufficient domain on the subject and that the most relevant is identified in this respect, with weaknesses in the knowledge of specialized aspects.

He does not have basic spelling or spelling errors.

It has a clear order in relation to the organization of the parts of the essay.

It has clear arguments.

A regular trial

It shows limited knowledge on the subject, although the most basic is identified.

It offers arguments based on other people’s research and hardly any data obtained by the author appears in a very basic investigation.

It has basic writing and spelling errors (accentuation or misuse of the rules of use of letters that represent common sounds such as B and V or S, C and Z).

A bad trial

It does not have a clear theme and the assumption is too broad or confusing.

The arguments do not allow to validate the assumption or hypothesis.

Most of the information is taken from outside sources.

It is riddled with spelling errors.

How it differs from other trials

The scientific test is different from other types of tests. Scientific trials of marketing, biology, physics, sociology or anthropology base their claims on specific theories of reference.

The scientific essays of other disciplines base their affirmations on the methodologically guided observation of reality or on the empirical experimentation proper to each science.

It essentially results from approximations to the reality of a qualitative, quantitative or mixed type. It shows statistics and hard data and its arguments are strictly factual.

Another type of essay does not require hard data or statements that result from experimentation or methodological observation of reality, but can be obtained from personal meditations or speculations. That moves them away from scientificity.

In short, do not forget that for there to be scientific testing, there must be research behind.
