How To Write A Lab Report For Biology?

05 May 2018Lab Report Writing Guides

If you are going to write a biology lab report for your college or university, you may need some guidelines how to write it.

The main aim of this work - an important part of an education - is to analyze your biology experiment and to show if you made this experiment successfully and understand all the processes that you observed during your work. Here you can find the guidelines for biology students. If you need a help in writing a biology lab report for college or university, follow this simple instruction.

The format may vary depending on the requirements of your teacher and class, thus, it is important to ask your teacher about the format of your report.

Biology Lab Report Format

What is an appropriate lab report format biology? A lab report for biology has a specific structure and format - let’s take a look at a common structure if you need to write lab report.

Abstract

Abstract informs about the purpose of an experiment and conclusions after it. In this part, you need to prepare five main sections - the purpose of the experiment, the problem, the methods that were used during your experiment, results of it, and conclusion. This information must be given in a clear manner and abstract is the last section you should write.

How should it look like? Here is a short example:

The particular experiment has been carried out in order to define the factors have a positive effect on the rates of enzyme reactions in cellular activities due to the fact that certain enzymes appear to be more effective than others. The catecholase activity of enzymes has been measured through its rate of absorption in a spectrophotometer, with the use of light that has a 540 nm wavelength. In the course of experiment we have compared samples with different concentration of enzymes. The comparison was based on their absorbance rates. The experiment has shown that those samples that had a higher concentration of enzymes, respectively showed the higher percent of absorption rate – the difference is significant, 95% against 24%. This proves that a higher production rate is ensured by a higher concentration of enzymes.

Introduction

The introduction section is one of the last parts that you should write. In lab reports biology, the introduction is like a framework for the whole text and it shows that you fully understood the theme and the purpose of the experiment.
In this part, it is good to select down the facts and references, and you can also use lecture notes. The introduction should not be too long and it has to contain the specified terminology related to the subject. It is usually not allowed to prove something in the introduction - you should only describe, not demonstrate the truth. You can also find sample biology lab report to check how this section has to be written. One of such is provided below.

Example:

It is a proven fact that enzymes are catalytic proteins that function is order to accelerate the reactions by means of lowering the activation energy (Campbell, 1996). In the experiment, we have studied the rate of reaction between oxygen and catechol and their ability to form benzoquinone in the condition when the concentration of enzymes (catecholase) was different. We suppose that the concentration of enzymes directly influences reaction rates.

Materials and Methods

This section students should write at the beginning, and it contains the explanation of the study that was conducted. In this part, you describe the whole procedure you did in order to help other students to do this experiment in the future. It is allowed to use diagrams in this part. You need to write about the measurement methods and techniques, indicate all sizes, quantify things, etc.

Be accurate and careful in this section!

Example:

Preparing the extract of catecholase, we used a washed, skinned, and diced potato and we have used a balance in order to get exactly 30 grams of the potato. We have also poured 150 ml of water into a beaker. We added water to the potato, removed the cover of a kitchen blender, and added both ingredients to a blender, then we put back on the cover and pressed the start button, observing the time. Then we pushed the button again to stop the blender. We have used four layers of cheese cloth to filter the result and then we stored the obtained extract in a clean, closed container.

Results

Here you need to present your findings to your audience in a clear way and orderly, and you can write this part almost at the beginning. The facts here could appear like a story that you want to tell your readers. Don’t use too many words - include only important information that should be concisely written. Organize all your facts in a logical fashion and do not interpret your results in this section. You also don’t need to describe your methods here. Here you need to figure out the trends that follow your facts which you have learnt during your experiment - try to call the reader’s attention to this trends or patterns.

Example:

Experimental group

Protein concentration (micg/micl)

Absorbance (595nm)

Media

2,04

0,57

Media/LPS

2,16

0,60

Drug

2,50

0,69

Drug/LPS

2,22

0,61

Discussion

After you have written the results, start to write a discussion. Here you have to write about your ideas after the experiment was demonstrated, and inform your readers about your thoughts that are based on the results of the experiment. There should be a comparison of your results and your expected findings.

Write in this section some information about if your results supported your thesis or there were variances. Your interpretation must be original and you can write from the specific to the general and do not prove or disprove your hypothesis. Add some original ideas to your interpretation and end with a concluding statement.

Example:

Proteins catalyze reactions by bringing down the energy of activation of the reaction; catecholase, an enzyme discovered in potato, changes catechol to benzoquinone within the sight of oxygen. We expected that more benzoquinone would be shaped within the sight of a more noteworthy measure of catecholase. This theory was proven by the outcomes acquired.

Catalysts are influenced by the environment – the level of pH present in the environment is one factor that can modify chemicals, while the rate at which the compound shape item is moderated or accelerated depending on how near to the standard the environment is.

Citing sources

The last part of your work is to cite the sourced that you have used in order to obtain them in the future.

Use internal citation in this section. You can find the instructions about how to cite sources in a lab report and ask your teacher about citation system that he or she requires; note that all references must be included at the end of your text: books, articles, lab manuals and other sources.

Example:

  • In-text – (Author, year);
  • Literature Cited page – Author last name and initials, year, title of an article or chapter, title of a book, journal, website or other source, editor’s name, publisher, city where published, pages.

Proofreading

After you have written your work, check it carefully to find grammar or spelling mistakes in it. Ensure that you followed required format and style and cited all the sources you have used. Do not forget to prepare your title page following special requirements and use a reasonable font for your work. The margins should not be bigger than 5 inches but this rule can vary in different classes. Include the page numbers, additional information, your full name, and the headings to your sections.

Lab reports are individual assignments - you may have a partner while your experiments but you always need to write the paper on your own. Do not plagiarize other works. You need to understand your material well and you also must understand which format and style of this work do you need.
