Biology Lab Report Example

When taking the course of general Biology, at some point, you will have to do lab experiments. The primary motive of writing a Biology lab report is to determine how you have performed your analysis and what you have understood during the whole process. A Biology lab report has a specific format that must be adhered to as the experiment is presented.

As you grasp the components that are most important, you will find that conveying the data is not too difficult. This lab report is generally descriptive; hence, you will be required to be well conversant with the analysis skill by stating the procedures followed and reporting your findings. If you require demystification on how you can do so, use the format below to guide you on knowing how to write Biology lab report.

Here is How to Write Biology Lab Report

Write Your Work in a Way that's Clear and Brief

This mainly applies as you write a statement that is scientific. The title should not only give a clear idea of the experiment, but also convey the results and make sure that it is not more than ten words. This is a precaution that must be taken if you want to be on the correct end of things as you write your report.

Introduction Writing in a Biology Lab Report

An introduction should be the framework in the biology lab report format. It merely gives a reader the first impression that you know what exactly the motive of your experiment is. To bring about this effect, you are needed to test your theory and write a brief statement of how you exactly intend to do it.

To ensure that you are well conversant with the understanding of your analysis, some instructors expect that you include the materials used, the observations and lastly the conclusions of the remarks made in sections of your Biology report.

For the reader to be in a position of understanding, the report must include the background information of the experiment. Here, you are needed to add the information relevant to the theoretical and historical background. This can be accomplished by having a published review of the literature. Below are some tips on writing an introduction:

  • First of all, you are required to explain more about the terminology, and you must tell it in the introduction.

  • Using the appropriate words in the explanation of whatever it is that you are doing. This is because you might be in a position where you have to describe something that does not exist in science. Due to this, your choice of words must reflect the message being conveyed in your report.

Summarizing Your Work With an Abstract

What is an abstract? This is a summary of your experiment. It includes information on the motive of the research, the issues that are being addressed and the methods that are used in problem-solving. In addition to this, it talks about the observations viewed in the analysis and the conclusions drawn from the study.

Often, this section of the Biology lab report should cover a length of 200-300 words. The abstract comes typically at the beginning of an experiment immediately after the title. To be on the safe side, you should compose a synopsis after you're done with the report.

Methods and the Materials that are going to be Used

This section would be used for the description of materials used and procedures involved in performing the analysis. You are not supposed to only record a list of the items but also indicate how and when they were used in the completion of your experiment. The data should not be too wordy, but it should be clear enough so that if a person were to use your instructions, it would serve them quite well.


This should be a collection of the data that is factual and must be obtained from the analysis. You should state the outcomes of the data in the text first, by using the visual aids to show the data. You should describe and explain to the reader the data derived from tables, pie charts and graphs in the text for the purpose of further understanding.

An example in a Biology lab report sample can be, "Increase in bacteria is discovered in temperatures that are higher as compared to the population of bacteria in areas with low temperature."

All in all, illustrations in your work should be well noted. To create ease for the reader to read your work, always present it in a format that explains the illustrations by having a paragraph that accompanies every chart, table and graph.

Identifying any Patterns within the Data

Make sure that any patterns in your work are made clear to the reader in the results. Do not explain the data in this section of the results, but tell it in the conclusion section.

Making Conclusions

In this section, you should summarize everything that occurred in the experiment. You can tackle this by highlighting the critical points of information from the data considered to be the most relevant when drawing your conclusion. Always remember to elaborate your data interpretation, for the sake of the reader's understanding.

Discussion of the Errors That Are Possible in the Analysis

You are needed to comment on what you perceived to be the cause of the mistake and offer an explanation of how the experiment can be corrected. By the data that is verified in your study, you are needed to discuss the errors. For example, "If humid conditions influenced an unexpected result," then mention it.

Do not state that humid conditions influenced the unexpected result while you do not have the necessary evidence for this. Such cases may cause errors that could be avoided easily.

Presenting One's Conclusion

This is where the outcome of the experiment is interpreted and presented in your Biology lab report. Convince your reader that you are more than capable of understanding the data intelligently. To be the greatest biology report writer, make this your primary goal. Agreeing or disagreeing with your theory in a lab report can be done quickly by stating, "The theory was disagreed or agreed on due to...." Then you can continue with the elaboration.

Always beware that having a conclusion that is longer does not make it any better. Present the information that you have in a way that coincides with your conclusion in a way that is logical.

Credit Should Be Given Where It Is Due

Ensure that the sources which aid you in gaining information are appropriately credited. One does not want their work of which time and money has been invested in to be discredited because of failing to cite sources. In case you did not know, learning institutions together with take cases of plagiarism with utmost seriousness.

So this is how you state a citation of a source in a formal way:

  • List the name of the author beginning with the last name then followed by the first name. An example can be: "Potter Harry."

  • The year which the article was published. Example "year published:1999."

  • Name of the volume of the journal example can be "whales 363(8765)9876

You should take note that all references are required to be mentioned at the ending of a Biology lab report sample. The texts include books, lab manuals, and even articles.


Borrowing of ideas from others can benefit you in the Biology lab report. However, you shouldn`t use numerous quotations in a lab report as they are among the things that professors don't like to see. You can paraphrase all of your sources and portray them in your own words making it unique in a way.

Craft your information into the text with a simple phrases so that you don't confuse the reader. Paraphrasing can be a confusing task hence you cannot just change some words. An example can be "most tutors don't want any quotations to be seen in a lab report." This sentence can be paraphrased as, "The use of quotations is disliked by majority of tutors." The trick here is that the idea can still be clear though the sentence has been portrayed originally and uniquely.

How to Format Your Report


Use a font that is reasonable. The size of the font must be 12 not unless you are specified otherwise by the instructors. Use traditional fonts as you write the report and the best to use is either Arial or Times New Roman.

Margins Are Required Not To Be Less Than 5 Inches

Some examiners prefer the margins to be in full inch. To be on the safer side, it is suggested that you consult your professor to know what is accepted in your class.

The Inclusion of Page Numbers

This means that you must place the number of each page so that you can produce a report that is consistent and well organized for the reader to read. You need to check if there is also any additional information like your final name on each page for the purpose of identity.

Though when it comes to where you are supposed to put the numbers, it is unknown because depending on the preference of the instructor, the numbers can be either placed at the top or the bottom. Therefore, it is advisable to ask your professor about their preference.

Adding of Headings in All the Sections in a Report

In every section of the Biology lab report, every part is required to be titled transparently and to do this a person should follow this order;

  1. The introduction.

  2. The procedures and materials used.

  3. The outcomes.

  4. Discussion of the findings.

  5. The citing of sources.


As you are tested on how to write Biology lab report. Always remember that the primary purpose of these reports is to determine how your experiments have been performed, how exactly you are going to portray the message of what you have discovered. To be good, you need to take a Biology lab report example that has been well written and go through it to see how to put this guide into practice. A biology lab report sample might be all you need to get some ideas on how to do your own!
