Now You Can Write Your Lab Report Like a Professional

lab report

Lab reports are often dull and boring, but they're an important part of any experiment. Anyone who has taken a science course in high school or college has had to write a lab report. But, what does it take to write a good one?

In this blog post, we'll outline the format of a lab report and give some tips on writing an engaging introduction and conclusion. Plus, we'll provide examples of lab reports for you to look at.

Let's get started!

What is a Lab Report?

Lab reports are an important part of any research project. The information they contain can be used to draw conclusions about the results.

A lab report can help you find out if there were any errors in procedure or analysis, which will ultimately lead you closer to solving your problem.

Sometimes they are assigned as a part of the course outline. Otherwise, you can make a lab report for your project on your own.

Follow the correct format and writing steps to write a good & complete report for your work.

Lab Report Format

The format for a lab report varies depending on the type of work done. Here is a format that you need to follow in order to write an impressive lab report:

  • The title page
  • A Title
  • An Abstract
  • An Introduction
  • The materials
  • Method
  • The data
  • The Results
  • Discussions
  • A Conclusion
  • Figures & graphs
  • The References
  • Appendices

The analysis and interpretation of lab reports is a vital part in any scientific study. Lab reports allow scientists to share their findings with other researchers, as well as being required by course or grant applications for research proposals at universities all over America.

How to Write a Lab Report?

Follow these steps and write a lab report:

  • Carefully read the instructions, and understand the requirements of the assignment.
  • Select a topic for your report, and collect information related to your work.
  • Come out with your hypothesis, and tell the reader about what they can expect from you.
  • Collect all the materials for your work. If you need equipment for the experiment, collect and organize them.
  • Then conduct your experiment by following a proper procedure. Record the experimental steps.
  • Analyze your work. Draw results from the experiment.
  • Finally, write the report. Add all the elements mentioned above in the format section.
  • Revise and proofread your report. Remove all grammatical and spelling mistakes. Make it a perfect report.


Your title should be clear and concise, providing the reader with enough information about what they are going to read. Titles often reflect your findings so you need one that's catchy but also meaningful.

Title your report that conveys the essence of your work done. Your title should be informative & it should help readers to get an idea about your work.

Title examples:

  • The effects of varying nitrogen levels on tomato plant height.
  • The Relationship Between Distance Traveled and Temperature Changes on Velocit
  • Testing the universality of the McGurk effect.
  • Measurement of Ionic Radii Using Ion Exchange Chromatography
  • Comparing the viscosity of common liquids found in kitchens.


An abstract is designed to condense a lab report into 150–300 words. It should provide readers with an overview of the research aims, methods and materials used in your study. As well as what was found at each stage throughout the experimentation level.

You can call the abstract as a preview of the work. Consider the following points to write the abstract of your report:

  • The wider context of your work.
  • You answer research questions.
  • The methodology used for experimentation.
  • Results.
  • The way you interpret the results.
  • The significance of your findings.

Example of an abstract:

The intake of nitrogen by plants is important for healthy growth and development. Tomatoes, one the most consumed fruits worldwide rely on this nutrient in order to create leaves or stems with tasty fruit attached! This experiment tested whether there were any links between different levels of fertilizer used (high vs low) & height measurements taken from tomato seedlings grown indoors under controlled conditions; it's been found that higher amounts do indeed lead taller plant stature compared against those who only get small shoots usualy around 2 inches tall.

The researchers found that by increasing the levels of nitrogen fertilizer, they could make their plants grow faster. This led to an increase in height for all three groups; however it is important not only when using these high amounts but also maintaining constant doses over time because if you stop giving them out then your plant will go back into crash mode causing its growth rate to come down again quickly even though there are still enough nutrients present!

The researchers found that by increasing the levels of nitrogen fertilizer, they could make their plants grow faster. This led to an increase in height for all three groups; however it is important not only when using these high amounts but also maintaining constant doses over time because if you stop giving them out then your plant will go back into crash mode causing its growth rate to come down again quickly even though there are still enough nutrients present!


The introduction section should introduce the reader with the basic idea of the work. You can use a funnel structure to write the introduction of the report:

  • Begin with the general discussion of the topic.
  • Narrow down the topic to the focus of your study.
  • Finally, state your research questions.

The goal of this section is to give the reader an idea about what your research topic entails and why it's important. You can either go into detail on previous studies that relate.

Example: Referring to previous research:

The researchers behind this new study wanted to know if there were any differences in the height of plants between high and low-income settings. They found that when tomatoes were grown with more nutrients, they grew taller - which is an indication for good health!

Then state your hypothesis. Give details about theoretical equations or laws related to the work.

Example: State your hypothesis

The importance of nitrogen for tomato plants made it seem likely that they would grow the tallest. The secondary hypothesis tested here is if low levels or no nutrients were given, then plant height would increase more than expected from an average stature base-line; this has been proven true in some cases!


You can include a detailed Method section in your lab report to document the procedures you used for gathering and analyzing data. This will allow others who read it, or evaluate these methods themselves, to follow what has been done step-by-step so they don't make any mistakes while reading the report.

If you need to include any long lists of procedural steps or materials, place them in the Appendices section but refer back to the method section, for a fuller explanation.

You should describe your experimental design, the people who will be taking part in it and any materials that may affect their experience. You can also talk about how you collected data from them or analyzed the things.

Experimental design

Lay down the experimental design that you used in your work.

Example: Experimental design

A between-subjects plan with three gatherings of tomato plants was utilized. The benchmark group got no nitrogen compost. The main exploratory gathering got a low degree of nitrogen compost, while the second trial bunch got an elevated degree of nitrogen manure.


Human subjects are often studied in terms of their demographic characteristics, but it is also common for scientists to look at the genetic background behind certain diseases or traits.

Count the number of subjects studied plus how you chose subjects for the work.


You will write down the material you used to collect data. In addition, if there are models of the equipment or software, you will also mention that.

Example: Materials

  • Rundown of materials
  • 35 Tomato seed
  • Soil
  • 15 plant pots (15 cm tall)
  • Water
  • Light lights (50,000 lux)
  • Nitrogen manure
  • Estimating tape

Experimental Settings

To better understand the effects of the experiment, it is important to provide lab reports and images that can help with setup. Explain how you controlled the variables, for instance, how you maintained room temperature at the lab.

Example: Experimental settings

To maximize the height of their plants, researchers confined a group if hemp seedlings to 12 hours worth video footage. They also restricted temperature and kept pH levels stable while providing them ample space in order reduce potential pests that could affect growth rates during this experiment .


Write the exact steps that you followed to carry out the experimentation. This will help other people to replicate your work and thus your work can benefit other researchers.

Example: Procedures

Tomatoes are one of the most popular vegetables in North America. But how do you grow them?rowing seedlings out on soil that's barely below ground level sounds like an impossible task! It takes patience and intentionality to create good farming practices for this crop- but it can be done with care, attention paid at every stage from sowing seeds all way until harvesting time comes around again.

Nitrogen is an important fertilizer for plants because it promotes green growth. The low concentration group received no treatment, while high concentrations were applied to both experimental groups of 5 pots each with labels indicating what they contained so that we could see how well our treatments worked!

After 50 days, the plants were measured and recorded. A tape was used to measure how high off ground they reached; this way we knew which plant had grown most in comparison with its peers!


It is important to report the results of any statistical analysis procedures that you undertake in your research. This will allow for transparency and honesty with readers, as well as aid future researchers who may wish to replicate or extend upon these findings.

Include the following in the result section of the report:

  • The significance of the results
  • Descriptive statistics
  • Statistical test results
  • Estimates of standard errors

Example: Results

The height of the plants in this experiment varied depending on their fertilizer level. The low-nitrogen group had shorter heights than all other groups, with an average around 20 centimeters for each type (controls included). There was also a significant difference between high nitrogen and nutrient rich dirt - 29cm versus 25+/-2 cm respectively!

The data supports the primary and secondary hypotheses. The high nitrogen group plants were significantly taller than low-nitrogen groups or controls, respectively; accordingly there was also an advantage to having more nutrients in this instance too!


The discussion of the results is important, it will portray your cognitive abilities. Include these things in the discussion party of the report:

  • Explain the results.
  • Comparison between the results and your expectations.
  • Source of experimental errors
  • Describe the unexpected results
  • Recommendations for future work

Example: Discussion

These results support the hypothesis that nitrogen levels affect plant height, with increasing amounts producing taller plants. These statistically significant findings are taken together with previous research to suggest how important it can be as a nutrient for tomato growth - especially when there's less available space and more competition than ever before!

This study is unique in that it focused on plant height as an indicator of growth. The researchers found that when they measured other indicators, like fruit yield or health status for example-the results were stronger than what was seen without these measurements!

The height of the plant was measured using a technique that may not be suitable for plants with extreme curvature. In order to accurately measure their heights, future studies should focus on alternative methods such as taking pictures or videos from different angles so researchers can get an accurate idea about how high these unique species really are!

The main strengths of this study were its rigorous controls for extraneous variables, such as pH and carbon levels in the soil. All other factors that could affect plant height are tightly controlled to isolate their effects on nitrogen intake resulting in high internal validity can be assumed with confidence by researchers who conducted it!


In this final section, summarize the findings of your experiment with a brief overview and implications for future research.
