Why science essays are important?

The key to writing a good science essay is making sure you understand the subject matter clearly. This will help you to organize your ideas and add accurate information. Before, you begin writing your science essay, it is a good idea to research different aspects of the topic.

Key points to remember when writing a science essay

Make sure you describe the scientific principles used in the experiment. This is very important so that your reader is able to repeat your experiment and get similar results.

Remember that as you write, it is your job to show the reader why your thesis is true! To do this, you will have to make sure to include an explanation of how and why the evidence supports your thesis.

Write in full sentences and avoid contractions. It’s a good idea to use transitional words (e.g., “next,” “in addition,” “first,” etc.) in order to help the reader follow along.

Do not forget that your main goal is to convince the reader of your viewpoint, so you have to be persuasive enough.

By sitting down and organizing all the information that needs inclusion in an outline first, this can help you decide on which facts and figures are worth mentioning and which ones should be ignored or omitted altogether.

What is the difference between a science essay and any other essay?

The thesis should be a concise statement of your main argument, but it cannot be just any opinion you happen to hold – it must be an argument that you can support with evidence from your sources.

You also need to avoid writing a thesis that’s too broad. This usually happens when one tries to make a universal statement about something they’re interested in but know very little about and end up answering a question that wasn’t actually asked or addressed in their assignment.

How to properly structure a science essay

  • Choosing a topic for a scientific essay is the first step.
  • Once you have chosen your topic, you must be sure to completely understand the concept of the essay.
  • You must then prepare an outline specifying every step from introduction to conclusion.
  • Keep in mind to find some samples (models) of similar writing and learn to observe the craft of the writer.

As seen in the picture below, most essays have a similar form that includes an introduction, body paragraphs, and a conclusion.


Your introduction should introduce the topic of the paper and explain why the topic is important. It should also include a hypothesis or thesis statement (your answer to the central question) and should briefly describe your reasons for this answer.

The introduction should not be too long: no more than 150 words is recommended.

The introduction tells the reader what they are going to read about. It should be written in such a way that it grabs the attention of the reader and keeps them reading. Your introduction should also include a statement of purpose, which explains why you are writing your science essay.


Your body paragraphs should contain evidence that supports your argument / thesis / hypothesis. Each body paragraph will be its own mini-essay where you try to prove one part of your argument.

The body paragraphs should support each other and work together to prove your thesis statement.

The main body is the most important part of your essay. It should contain all the ideas you want to convey through your paper. In order to compose a well-structured piece of writing, you need to have a plan before you start writing.

This will make it easier for you to organize your thoughts and ideas.


Conclusion paragraph is where you wrap up all of your ideas into one concisely written statement that sums up everything.

The conclusion is usually about three sentences long and provides closure for your science essay. In this section, you may want to summarize some of the points you made in the introduction and body paragraphs, but do not repeat yourself too much.

To summarize the introduction should also include a strong thesis statement that will give you a map to follow when writing. The body of your essay should support your thesis statement by providing evidence for your arguments. A strong conclusion will summarize the main points of your essay and wrap it up with a final analysis or statement.

Diagrams and References

The illustrations or diagrams that explain the content need to be attached separately as annexes in the end of the writing. These need to be numbered and referred in the body when the fact from the diagram is mentioned.

References should be listed as an annexure. The list of references should be numbered according to the order they are mentioned in the text. Throughout the text when you need to mention a reference a numeric should be written at the end of the fact in the body of the essay.
