A lab report describes an entire experiment from start to finish, outlining the procedures, reporting results, and analyzing data. The report is used to demonstrate what has been learned, and it will provide a way for other people to see your process for the experiment and understand how you arrived at your conclusions. The conclusion is an integral part of the report; this is the section that reiterates the experiment’s main findings and gives the reader an overview of the lab trial. Writing a solid conclusion to your lab report will demonstrate that you’ve effectively learned the objectives of your assignment.

How to Write a Lab Report Conclusion

• Restate the purpose of the experiment and your procedures.
• Describe the results or findings and if they support your hypothesis.
• Mention what you've learned from the experiment.
• Note any errors or uncertainties that could affect the results.
• Propose experiments for the future to gain more findings.

Outlining Your Conclusion

• Restate : Restate the lab experiment by describing the assignment.
• Explain : Explain the purpose of the lab experiment. What were you trying to figure out or discover? Talk briefly about the procedure you followed to complete the lab.
• Results : Explain your results. Confirm whether or not your hypothesis was supported by the results.
• Uncertainties : Account for uncertainties and errors. Explain, for example, if there were other circumstances beyond your control that might have impacted the experiment’s results.
• New : Discuss new questions or discoveries that emerged from the experiment.

• Your assignment may also have specific questions that need to be answered. Make sure you answer these fully and coherently in your conclusion.

Discussing the Experiment and Hypothesis

• If you tried the experiment more than once, describe the reasons for doing so. Discuss changes that you made in your procedures.
• Brainstorm ways to explain your results in more depth. Go back through your lab notes, paying particular attention to the results you observed.

• Start this section with wording such as, “The results showed that…”
• You don’t need to give the raw data here. Just summarize the main points, calculate averages, or give a range of data to give an overall picture to the reader.
• Make sure to explain whether or not any statistical analyses were significant, and to what degree, such as 1%, 5%, or 10%.

• Use simple language such as, “The results supported the hypothesis,” or “The results did not support the hypothesis.”

Demonstrating What You Have Learned

• If it’s not clear in your conclusion what you learned from the lab, start off by writing, “In this lab, I learned…” This will give the reader a heads up that you will be describing exactly what you learned.
• Add details about what you learned and how you learned it. Adding dimension to your learning outcomes will convince your reader that you did, in fact, learn from the lab. Give specifics about how you learned that molecules will act in a particular environment, for example.
• Describe how what you learned in the lab could be applied to a future experiment.

• On a new line, write the question in italics. On the next line, write the answer to the question in regular text.

• If your experiment did not achieve the objectives, explain or speculate why not.

Wrapping Up Your Conclusion

• If your experiment raised questions that your collected data can’t answer, discuss this here.

• Describe what is new or innovative about your research.
• This can often set you apart from your classmates, many of whom will just write up the barest of discussion and conclusion.

Community Q&A

• Ensure the language used is straightforward with specific details. Try not to drift off topic. Thanks Helpful 1 Not Helpful 0
• Once again, avoid using personal pronouns (I, myself, we, our group) in a lab report. The first-person point-of-view is often seen as subjective, whereas science is based on objectivity. Thanks Helpful 1 Not Helpful 0
• If you include figures or tables in your conclusion, be sure to include a brief caption or label so that the reader knows what the figures refer to. Also, discuss the figures briefly in the text of your report. Thanks Helpful 1 Not Helpful 0

• Take care with writing your lab report when working in a team setting. While the lab experiment may be a collaborative effort, your lab report is your own work. If you copy sections from someone else’s report, this will be considered plagiarism. Thanks Helpful 4 Not Helpful 0

How to Write a Good Conclusion For a Lab Report

Writing a good conclusion for your science lab report can be the difference between a good grade and a great one. It's your last chance to show you understand the experiment and why it matters. This article will help you learn how to write a lab conclusion that sums up your work and shows your teacher that you understood what you did.

What Should Be in Your Lab Report Conclusion?

A good lab report conclusion wraps up your lab work in a neat package. When you're thinking about how to write a conclusion for a lab report, focus on four main things. First, remind everyone in a sentence or two of your experiment objectives. Then, quickly mention how you did the experiment and what you found out, but don't introduce new ideas.

Next, talk about the most important things you learned from your experiment. Show how what you found out connects to what you initially tried to do. Lastly, think briefly about what your work means or any limitations you faced during the process. You may include suggestions for further investigation but refrain from proposing solutions.

How to Write a Lab Report Conclusion

To write a good lab conclusion, follow these steps:

• Remind the reader why you did the experiment and its aims. 
• Describe how you did the experiment and what tools you used.
• Briefly discuss the samples used and the results obtained.
• Provide a short analysis, including your arguments and assumptions.
• Relate your findings to the broader scientific context of your discipline.

Important: Keep your conclusion short and easy to understand. A lab conclusion should be about 200-300 words or one paragraph. But if your experiment was really complex, you might need up to 500 words.

Remember, your lab conclusion is part of a bigger report. Always make sure your whole report is well-organized, with a title, introduction, how you did things, what you found, what it means, conclusion, and a list of where you got your information. If you have a lot of numbers or calculations, put them at the end in a separate section to make your report easier to read.

A Sample Lab Report Conclusion

Here's an example of how to write a scientific conclusion for a plant experiment:

The experiment examined how various light wavelengths impact tomato seedling growth. Our findings revealed that blue light (450-495 nm) significantly enhanced stem elongation and leaf surface area in tomato seedlings compared to red (620-750 nm) or full-spectrum white light. Throughout the 4-week study, seedlings exposed to blue light achieved an average height of 15.3 cm, surpassing those exposed to red (10.7 cm) and white light (12.1 cm).  These results align with our hypothesis that blue light promotes more vigorous vegetative growth in tomato seedlings, potentially due to its activation of phototropins and cryptochromes. While these outcomes provide valuable insights into early-stage tomato plant development, additional research is necessary to determine the long-term effects on fruit production and quality. This study contributes to our understanding of optimizing light conditions for improved seedling growth in controlled agricultural environments.

This example shows the important parts of a good lab conclusion: it reminds us what the experiment was for, tells how it was done, shares the results, and explains what it all means.

Useful Tips for Improving Your Lab Conclusion

To make your conclusion lab report better, try these tips:

• Review your grading rubric to ensure you meet all requirements.
• Maintain an appropriate tone (explanatory, descriptive, or process-oriented).
• Keep your notes nearby so you can check your facts.
• Use your own words to say what you were trying to do; don't just copy from your lab instructions.
• Use passive voice and past tense , typically avoiding first-person perspective. Most lab reports are written in the third person.

When writing a discussion lab report, focus on clarity and sticking to what's important. Don't add new information or discuss things that aren't part of your experiment.

Making Your Scientific Conclusion Clear and Impactful

Writing a great lab report conclusion doesn't have to be hard. With the tips we've discussed on writing a scientific conclusion, you can now write good summaries of your science work. Remember, when writing your discussion lab report, stay focused on your experiment and what you found out. Don't talk about things that aren't related or say things you can't prove. Instead, explain your results, their meaning, and why they matter in science.

Year 9 science, year 10 science.

Is your teacher expecting you to write an experimental report for every class experiment? Are you still unsure about how to write a scientific report properly? Don’t fear! We’ll guide you through all parts of a scientific report, step-by-step.

How to write a scientific report:

• What is a scientific report
• General rules for writing Scientific reports
• Introduction/Background information
• Risk assessment

What is a scientific report?

A scientific report documents all aspects of an experimental investigation. This includes:

• The aim of the experiment
• The hypothesis
• An introduction to the relevant background theory
• The methods used
• The results
• A discussion of the results
• The conclusion

Scientific reports allow their readers to understand the experiment without doing it themselves. These reports also give others the opportunity to check the methodology of the experiment to ensure the validity of the results.

A scientific report is written in several stages. We write the introduction, aim, and hypothesis before performing the experiment, record the results during the experiment, and complete the discussion and conclusions after the experiment.

But, before we delve deeper into how to write a scientific report, we need to have a science experiment to write about! Choose an experiment to use as an example from our 7 Simple Experiments You Can Do At Home article.

General rules for writing scientific reports

Learning how to write a scientific report is different from writing English essays or speeches.

You have to use:

• Passive voice (which you should avoid when writing for other subjects like English!)
• Past-tense language
• Headings and subheadings
• A pencil to draw scientific diagrams and graphs
• Simple and clear lines for scientific diagrams
• Tables and graphs where necessary

Structure of scientific reports

Now that you know the general rules on how to write scientific reports, let’s look at the conventions for their structure!

The title should simply introduce what your experiment is about.

The Role of Light in Photosynthesis

2. Introduction/Background information

Write a paragraph that gives your readers background information to understand your experiment.

This includes explaining scientific theories, processes, and other related knowledge.

Photosynthesis is a vital process for life. It occurs when plants intake carbon dioxide, water, and light, and results in the production of glucose and water. The light required for photosynthesis is absorbed by chlorophyll, the green pigment of plants, which is contained in the chloroplasts.

The glucose produced through photosynthesis is stored as starch, which is used as an energy source for the plant and its consumers.

The presence of starch in the leaves of a plant indicates that photosynthesis has occurred.

The aim tells us what is going to be tested in the experiment. This should be short, concise, and clear.

The aim of the experiment is to test whether light is required for photosynthesis to occur.

4. Hypothesis

The hypothesis is what you predict the outcome of the experiment will be. You have to use background information to make an educated prediction.

It is predicted that photosynthesis will occur only in leaves that are exposed to light and not in leaves that are not exposed to light. This will be indicated by the presence or absence of starch in the leaves.

5. Risk assessment

Identify the hazards related to the experiment and explain how you would prevent or minimise the risks. A hazard is something that can cause harm, and a risk is how likely it is that harm will occur because of the hazard.

A table is an excellent way to present your risk assessment.

Remember, you have to specify the  type of harm that can occur because of the hazard. It’s not enough to simply identify the hazard.

• Do not write:  “Scissors are sharp.”
• Instead, write: “Scissors are sharp and can cause injury.”

The method has 3 parts:

• A list of every material used
• Steps of what you did in the experiment
• A scientific diagram of the experimental apparatus

Let’s break down what you need to do for each section.

6a. Materials

This must list every piece of equipment and material used in the experiment.

Remember, you need to specify the amount of each material you used.

• 1 geranium plant
• Aluminium foil
• 2 test tubes
• 1 test tube rack
• 1 pair of scissors
• 1 250 mL beaker
• 1 pair of forceps
• 1 10 mL measuring cylinder
• Iodine solution (5 mL)
• Methylated spirit (50 mL)
• Boiling water
• 2 Petri dishes

As a rule of thumb, you should write the method clearly and in a way that readers can repeat the experiment and get similar results.

Using a numbered list for the steps of your experimental procedure is much clearer than writing a whole paragraph of text.  The steps should:

• Be written in a sequential order, based on when they were performed
• Specify any equipment that was used
• Specify the quantity of any materials that were used

You also need to use past tense and passive voice when you’re writing your method. Scientific reports are supposed to show the readers what you did in the experiment, not what you will do.

• Aluminium foil was used to fully cover a leaf of the geranium plant. The plant was left in the sun for three days.
• On the third day, the covered leaf and 1 non-covered leaf were collected from the plant. The foil was removed from the covered leaf, and a 1 cm square was cut from each leaf using a pair of scissors.
• 150 mL of water was boiled in a kettle and poured into a 250 mL beaker.
• Using forceps, the 1 cm square of covered leaf was placed into the beaker of boiling water for 2 minutes. It was then placed in a test tube labelled “dark”.
• The water in the beaker was discarded and replaced with 150 mL of freshly boiled water.
• Using forceps, the 1 cm square non-covered leaf was placed into the beaker of boiling water for 2 minutes. It was then placed in a test tube labelled “light”.
• 5 mL of methylated spirit was measured with a measuring cylinder and poured into each test tube so that the leaves were fully covered.
• The water in the beaker was replaced with 150 mL of freshly boiled water and both the “light” and “dark” test tubes were immersed in the beaker of boiling water for 5 minutes.
• The leaves were collected from each test tube with forceps, rinsed under cold running water, and placed onto separate labelled Petri dishes.
• 3 drops of iodine solution were added to each leaf.
• Both Petri dishes were placed side by side and observations were recorded.
• The experiment was repeated 5 times, and results were compared between different groups.

6c. Diagram

After you complete your steps, it’s time to draw your scientific diagrams! Here are some rules for drawing scientific diagrams:

• Always use a pencil to draw your scientific diagrams.
• Use simple, sharp, 2D lines and shapes to draw your diagram. Don’t draw 3D shapes or use shading.
• Label everything in your diagram.
• Use thin, straight lines to label your diagram. Don’t use arrows.
• Ensure that the label lines touch the outline of the equipment you are labelling and do not cross over it or stop short of it.
• The label lines should never cross over each other.
• Use a ruler for any straight lines in your diagram.
• Draw a sufficiently large diagram so all components can be seen clearly.

This is where you document the results of your experiment. The data that you record for your experiment will generally be qualitative and/or quantitative.

Qualitative data is data that relates to qualities and is based on observations (qualitative – quality). This type of data is descriptive and is recorded in words. For example, the colour changed from green to orange, or the liquid became hot.

Quantitative data refers to n umerical data (quantitative – quantity). This type of data is recorded using numbers and is either measured or counted. For example, the plant grew 5.2 cm, or there were 5 frogs.

The way you record your results is important. Most of the time, a table is the best way to do this.

Here are some rules to using tables

• Use a pencil and a ruler to draw your table.
• Draw neat and straight lines.
• Ensure that the table is closed (connect all your lines).
• Don’t cross your lines (erase any lines that stick out of the table).
• Use appropriate columns and rows.
• Properly name each column and row (including the units of measurement in brackets).
• Do not write your units in the body of your table (units belong in the header).
• Always include a title.

Note : If your results require calculations, clearly write each step.

Observations of the effects of light on the amount of starch in plant leaves.

If quantitative data was recorded, the data is often also plotted on a graph.

8. Discussion

The discussion is where you analyse and interpret your results, and identify any experimental errors or possible areas of improvements.

You should divide your discussion as follows.

1. Trend in the results

Describe the ‘trend’ in your results. That is, the relationship you observed between your independent and dependent variables.

The independent variable is the variable that you’re changing in the experiment. In this experiment, it’s the amount of light that the leaves are exposed to.

The dependent variable is the variable that you’re measuring in the experiment. In this experiment, it’s the presence of starch in the leaves.

The presence of starch is indicated when the addition of iodine causes the leaf to turn dark purple. The results show that starch was present in the leaves that were exposed to light, while the leaves that were not exposed to light did not contain starch.

2. Scientific explanation

Give an explanation of the results using scientific knowledge, theories, and any other scientific resources you find.

As starch is produced during photosynthesis, these results show that light plays a key role in photosynthesis.

3. Validity 

Validity refers to whether or not your results are valid. This can be done by examining your variables.

VA lidity =  VA riables

Identify the independent, dependent, controlled variables, and the control experiment (if you have one).

The controlled variables are the variables that you keep the same across all tests e.g. the size of the leaf sample.

The control experiment is where you don’t apply an independent variable. It is untouched for the whole experiment.

Ensure that you never change more than one variable at a time!

The independent variable of the experiment was the amount of light that the leaves were exposed to (the covered and uncovered geranium leaf), while the dependent variable was the presence of starch. The controlled variables were the size of the leaf sample, the duration of the experiment, the amount of time the solutions were heated, and the amount of iodine solution used.

4. Reliability 

Identify how you ensured the reliability of the results.

RE liability = RE petition

Show that you repeated your experiments, cross-checked your results with other groups, or collated your results with the class.

The reliability of the results was ensured by repeating the experiment 5 times and comparing results with other groups. Since other groups obtained comparable results, the results are reliable.

5. Accuracy

You should discuss accuracy if your results are in the form of quantitative data (numerical), and there is an accepted value for the result.

Accuracy wouldn’t be discussed for our photosynthesis experiment as qualitative data was collected. But, it would be discussed if we were measuring gravity using a pendulum:

The measured value of gravity was 9.8 m/s 2 , which is in agreement with the accepted value of 9.8 m/s 2 .

6. Possible improvements 

Point out any errors or risks you found in the experiment and suggest a method to improve it.

If there are none, then suggest new ways to improve the experimental design, and/or minimise error and risks.

Possible improvements could be made by including control experiments. For example, testing whether the iodine solution turns dark purple when added to water or methylated spirits. This would help to ensure that the purple colour observed in the experiments is due to the presence of starch in the leaves rather than impurities.

9. Conclusion

State whether the aim was achieved and if your hypothesis was supported.

The aim of the investigation was achieved, and it was found that light is required for photosynthesis to occur. This was evidenced by the presence of starch in leaves that had been exposed to light, and the absence of starch in leaves that had been unexposed. These results support the proposed hypothesis.

Writing a conclusion for a science experiment is a crucial step in the scientific process. It summarizes the main findings of the experiment, interprets the results, and provides recommendations for future research. A well-written conclusion can make or break the credibility of the experiment, so it’s essential to get it right. In this article, we’ll provide a step-by-step guide on how to write a conclusion for a science experiment.

What is a Conclusion?

A conclusion is a summary of the main findings of the experiment, including the results, implications, and limitations. It’s the final section of the experiment report, and it should provide a clear and concise overview of the experiment’s outcomes.

Key Components of a Conclusion

A conclusion typically includes the following key components:

• Restate the Research Question : Restate the research question or hypothesis in your own words to provide context for the experiment.
• Summarize the Main Findings : Summarize the main findings of the experiment, including the results, trends, and patterns.
• Interpret the Results : Interpret the results in the context of the research question and previous studies.
• Discuss the Implications : Discuss the implications of the results, including their significance, relevance, and potential applications.
• Limitations and Future Research : Identify the limitations of the experiment and suggest areas for future research.

How to Write a Conclusion

Here’s a step-by-step guide on how to write a conclusion for a science experiment:

Table of Contents

Step 1: Restate the Research Question

Restate the research question or hypothesis in your own words to provide context for the experiment. This will help readers understand the purpose of the experiment and what you were trying to achieve.

"The purpose of this experiment was to investigate the effect of temperature on the growth rate of bacteria. Specifically, we aimed to determine whether a higher temperature would result in a faster growth rate."

Step 2: Summarize the Main Findings

Summarize the main findings of the experiment, including the results, trends, and patterns. Use bullet points or a table to make it easy to read and understand.

"The results of the experiment showed that:

• The growth rate of bacteria increased with increasing temperature.
• The highest growth rate was observed at 37°C.
• The growth rate was significantly slower at 20°C.

Step 3: Interpret the Results

Interpret the results in the context of the research question and previous studies. Explain what the results mean and why they are important.

"The results of this experiment support the hypothesis that a higher temperature would result in a faster growth rate. This is consistent with previous studies that have shown that bacteria grow faster at higher temperatures. The implications of this finding are significant, as it suggests that bacteria can grow rapidly in environments with high temperatures, which could have important implications for public health and food safety."

Step 4: Discuss the Implications

Discuss the implications of the results, including their significance, relevance, and potential applications. Highlight the potential benefits and limitations of the findings.

"The implications of this study are significant, as it suggests that bacteria can grow rapidly in environments with high temperatures. This could have important implications for public health, as it highlights the need for proper food handling and storage practices to prevent bacterial growth. Additionally, this study could have implications for the development of new antimicrobial agents that target bacteria at high temperatures."

Step 5: Limitations and Future Research

Identify the limitations of the experiment and suggest areas for future research. Highlight the potential biases and errors that could have affected the results.

"This study had several limitations, including the use of a small sample size and the lack of control over environmental factors. Future studies could address these limitations by using a larger sample size and controlling for environmental factors. Additionally, future studies could investigate the effect of temperature on the growth rate of different types of bacteria to provide a more comprehensive understanding of the relationship between temperature and bacterial growth."

Writing a conclusion for a science experiment requires careful consideration of the main findings, implications, and limitations of the experiment. By following the steps outlined in this article, you can write a clear and concise conclusion that summarizes the main findings and provides a clear direction for future research. Remember to restate the research question, summarize the main findings, interpret the results, discuss the implications, and identify limitations and areas for future research.

• How to Write Discussions and Conclusions

The discussion section contains the results and outcomes of a study. An effective discussion informs readers what can be learned from your experiment and provides context for the results.

What makes an effective discussion?

When you’re ready to write your discussion, you’ve already introduced the purpose of your study and provided an in-depth description of the methodology. The discussion informs readers about the larger implications of your study based on the results. Highlighting these implications while not overstating the findings can be challenging, especially when you’re submitting to a journal that selects articles based on novelty or potential impact. Regardless of what journal you are submitting to, the discussion section always serves the same purpose: concluding what your study results actually mean.

A successful discussion section puts your findings in context. It should include:

• the results of your research,
• a discussion of related research, and
• a comparison between your results and initial hypothesis.

Tip: Not all journals share the same naming conventions.

You can apply the advice in this article to the conclusion, results or discussion sections of your manuscript.

Our Early Career Researcher community tells us that the conclusion is often considered the most difficult aspect of a manuscript to write. To help, this guide provides questions to ask yourself, a basic structure to model your discussion off of and examples from published manuscripts. 

Questions to ask yourself:

• Was my hypothesis correct?
• If my hypothesis is partially correct or entirely different, what can be learned from the results? 
• How do the conclusions reshape or add onto the existing knowledge in the field? What does previous research say about the topic? 
• Why are the results important or relevant to your audience? Do they add further evidence to a scientific consensus or disprove prior studies? 
• How can future research build on these observations? What are the key experiments that must be done? 
• What is the “take-home” message you want your reader to leave with?

How to structure a discussion

Trying to fit a complete discussion into a single paragraph can add unnecessary stress to the writing process. If possible, you’ll want to give yourself two or three paragraphs to give the reader a comprehensive understanding of your study as a whole. Here’s one way to structure an effective discussion:

Writing Tips

While the above sections can help you brainstorm and structure your discussion, there are many common mistakes that writers revert to when having difficulties with their paper. Writing a discussion can be a delicate balance between summarizing your results, providing proper context for your research and avoiding introducing new information. Remember that your paper should be both confident and honest about the results! 

• Read the journal’s guidelines on the discussion and conclusion sections. If possible, learn about the guidelines before writing the discussion to ensure you’re writing to meet their expectations. 
• Begin with a clear statement of the principal findings. This will reinforce the main take-away for the reader and set up the rest of the discussion. 
• Explain why the outcomes of your study are important to the reader. Discuss the implications of your findings realistically based on previous literature, highlighting both the strengths and limitations of the research. 
• State whether the results prove or disprove your hypothesis. If your hypothesis was disproved, what might be the reasons? 
• Introduce new or expanded ways to think about the research question. Indicate what next steps can be taken to further pursue any unresolved questions. 
• If dealing with a contemporary or ongoing problem, such as climate change, discuss possible consequences if the problem is avoided. 
• Be concise. Adding unnecessary detail can distract from the main findings. 

Don’t

• Rewrite your abstract. Statements with “we investigated” or “we studied” generally do not belong in the discussion. 
• Include new arguments or evidence not previously discussed. Necessary information and evidence should be introduced in the main body of the paper. 
• Apologize. Even if your research contains significant limitations, don’t undermine your authority by including statements that doubt your methodology or execution. 
• Shy away from speaking on limitations or negative results. Including limitations and negative results will give readers a complete understanding of the presented research. Potential limitations include sources of potential bias, threats to internal or external validity, barriers to implementing an intervention and other issues inherent to the study design. 
• Overstate the importance of your findings. Making grand statements about how a study will fully resolve large questions can lead readers to doubt the success of the research.
