Abstract or Summary
This section is often written last and summarizes the purpose of the experiment and
your findings. It gives the reader a quick overview of what you’ve done and what you’ve
learned. It should include the following information: the purpose of the experiment, the
problem, the methods that were used during your experiment, the results of it, and the
conclusion. Make sure this information is given in a clear manner so that it is easy for
the reader to understand.
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 the experiment, we compared samples with a 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 also. In biology lab
reports, the introduction is like a framework for the whole text and it shows that you fully
understood the topic and the purpose of the experiment. This section should describe
the problem or hypothesis you are investigating. The introduction should include the
reason your are studying the problem and any useful outside information related to the
problem or hypothesis. 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.
Example:
It is a proven fact that enzymes are catalytic proteins whose function is to accelerate reactions
by means of lowering activation energy (Campbell, 1996). In the experiment, we studied the rate
of reaction between oxygen and catechol and their ability to form benzoquinone in a condition
where the concentration of enzymes (catecholase) was different. We supposed that the
concentration of enzymes directly influences reaction rates.
Materials and Methods
Write this section at the beginning and have it contain an explanation of the study that
was conducted. It should be written in the past tense and passive voice. In this part,
you describe the whole procedure you did in the order you did it to help other scientists
do this experiment in the future. Describe your procedure, the materials you used, how
you gathered and analyzed your data, and the controls in your experiments.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, detailed, and careful in this section!
For example:
Three 50 mL beakers were each filled with 25 mL of water.
Do not write​:
I filled three beakers with water.
Example:
Preparing an extract of catecholase, we used a washed, skinned, and diced potato and we used
a scale in order to get precisely 30 grams of potato. We 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, we then put the cover back on and pressed the start button, noting the
time. Then we pushed the button again to stop the blender. We used four layers of cheesecloth
to filter the result and then we stored the obtained extract in a clean, closed container.
Results
Here you need to present the findings to your audience in a clear, orderly way. You can
write this part almost at the beginning. The facts here could appear like a story that you
want to tell your readers. Describe what you found out through the experiments. Results
include your observations, measurement data, graphs, and tables. Calculations and
answers to all lab questions should be included. Don’t use too many words - include
only important information and write it in a brief but understandable way. Organize all
your facts in a logical way but ​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 learned during your experiment - try to call the reader’s
attention to trends or patterns.

Discussion
After you have written the results, start to write a discussion. Here you have to write
about your ideas after the experiment was conducted 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 whether your results supported your thesis
or there were variances. Your interpretation must be original and you can write from
being specific to 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 activation energy of the reaction; catecholase,
an enzyme discovered in potato, changes catechol to benzoquinone with the presence of
oxygen. We expected that more benzoquinone would be shaped by the presence 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.
Literature Cited
The last part of your work is to cite the source that you have used in order to reference
them in the future. Use MLA format.
