Students pursuing science fields such as chemistry will tell you how tricky it gets when writing lab report conclusions. After all the hard work – the tedious research process and analyzing your findings – a decision can mess you up! The conclusion of a basic lab report can either make or break your paper. That is why you need this professional ‘how to write a lab report’ guide to see you through. College and university students will find this post helpful.

What Is A Lab Report Conclusion?

Now, a lab report is a presentation of the results gotten after experimenting in the laboratory. It brings together all the activities, equipment, methods, and findings during a lab’s scientific investigation.

Lab report conclusions sum up all the procedures and results discussed in the lengthy part of the paper. Just like any other conclusion, it restates the goals, methods, final data, and notes on the experiment. It shows whether you were able to answer your research question successfully or not. A reader can extract all the essential points of your report from this crucial part.

A quality lab report conclusion serves several purposes:

  • It documents your findings
  • It communicates the significance of your findings

  • The writer can influence the reader through this section
  • It enables you to restate the objective of the investigation in a concise manner

We can say much about the necessity of an excellent lab report conclusion. However, it remains evident that this conclusive part of a science lab report format carries much weight – not that the others are inferior.

Before we proceed, here is something worth your time:

What Is The Importance Of Calculations In A Lab Report?

A science experiment report includes various components, one of them being calculations. Now I know that some biology or chemistry students are already groaning at the thought of this part. However, measures play a very critical role in presenting the results of your experiment. Here are reasons why?

  • They show the authenticity of your experiment.
  • Calculations are a true mark of the accuracy involved in preparing a lab report.
  • They form the basis of the arguments in the discussion paragraphs
  • Calculations are easy to follow as compared to long essays

Since science experiments involve data collection, you may need to jot down the millimeters of water, hydrochloric acid, or methylbenzene used in your investigation. These will serve as a yardstick in the application of your findings. A reader will know that if he/she uses a certain percentage of a catalyst, then it will limit the results to a certain extent. It will prevent generalizations and thus promoting the values of accuracy and preciseness in science research.

How To Write A Discussion And Conclusion For A Lab Report – Structure

A lab report conclusion outline is necessary for meeting the particular needs of a course or professor. Understanding the lab report structure will help you know the basic concepts, pieces, and purpose of a laboratory report conclusion. Here is a brief discussion of the several elements of a lab report:

  • Title page: It contains the name of the experiment, lab partners, and date.
  • Abstract: Summarizes the purpose, key findings, significance, and significant conclusions
  • Introduction: Includes the objective and background of the experiment
  • Methods and materials: A list of what you used in your experiment
  • Experimental procedure: A description of the process in a chronological order
  • Results: Involve calculations, tables, and figures
  • Discussion: It involves explaining, analyzing, and interpreting
  • Conclusion: A restatement of the lab results
  • References: A list of sources used, including your lab manual
  • Appendices: Entails elements not included in the report

Now that we know how a general lab report looks, it will be easier to understand the conclusion. A lab report conclusion example should contain the following key elements:

  • A restatement of the experiment’s goals: The best lab report conclusion begins with restating the investigation’s purposes. Ensure that summarize the question(s) you intended to answer and a summary of the hypotheses you made for your investigation results.
  • A brief description of the methods used: Shortly mention some of the ways you used in performing your experiment. Please do not make it a comprehensive list, as you have already pointed out in the body paragraphs. Only the most essential substances and tools should appear here. You can also explain why you chose the methods briefly.
  • A precise analysis of your final data: You should present all the data obtained in the experiment together with a detailed but conclusive analysis of them. Please note that the data presented here is only the final one you’d have determined from the study.
  • Did your experiment succeed or fail? Weigh the data alongside your goals and predictions for the investigation. Determine whether you were able to answer all the questions set out in the introduction. Give reasons for either case and also state the lessons learned from your experiment. You can also tell your reader which of your initial hypothesis were true. It is also prudent to suggest improvements for better results next time.

And that is how to write a conclusion for a biology lab report for top grades! To understand this structure better, you can borrow this method, RERUN, which stands for:

  • Restate
  • Explain
  • Results
  • Uncertainties
  • New questions or discoveries

It is a good idea to always consult your supervisor first before beginning your lab report. Different institutions may have their own unique in-house writing standards though these guidelines are a general rule of thumb.

How Long Should A Lab Report Conclusion Be?

Again, this will depend on the type of lab report you are writing. If you are writing a lab report of one page, then a couple of sentences can do this section (circa 40 words). However, it should be able to capture all the elements discussed above in their entirety.

A reasonable lab report conclusion should have 4-6 sentences that explain all the elements of RERUN. You can also check with your institution’s marking key to determine the length of a lab report conclusion.

Trusted Tips On How To End A Conclusion In A Lab Report

The end of any writing project justifies if you understood the concept clearly or not. Therefore, once you’ve discussed all the significant findings of your experiment, it is essential to end in a manner that impresses the reader. You can achieve this by:

  • Pointing out exciting points and discoveries that are in your report
  • Relating the significance of the experiment and its findings to real-world problems
  • Suggesting practical adjustments for next time

It would help if you left the reader feeling satisfied with your paper and not having more questions than answers.

Here is a rubric for conclusion paragraphs in lab reports that you can use:

  • Have I restated the purpose?
  • Does my conclusion state the significant findings while referring to graphs or data tables?
  • Revisit the hypotheses – Do the findings of the experiment support them?
  • Have I stated possible improvements to the lab procedure?
  • Have I suggested extensions to the lab?

Once you are done with your paper, it is always good to read through the full report. It will help you identify whether your information is logical or not. It will also show you instances of contradictions if any. Since a report includes calculations, it is important to double-check whether the figures used are accurate. Inaccuracies in figures may lead to wrong findings and conclusions.

Remember that lab reports do not use personal pronouns. Since science is based on objectivity, avoid using such subjective pronouns in our lab report conclusion. A straightforward language with specific details will guarantee you top grades in your lab report.

Lab Report Conclusion Template

Restate: We set out to test the acidity level in bean soy using a PH scale; the experiment’s objective was to confirm that the acidity should be 6.00. The results showed that beans soy were at precisely 6.00.

Explain: The results supported the hypothesis that the proper PH of beans soy is 6.00. However, this is dependent on the time of harvesting.

Results: After comparing three separate beans soy harvested samples at different times, only the mature beans soy tested 6.00. The experiment supported the hypothesis.

Uncertainties: It was challenging to affirm the time of the year when different bean soy was harvested.

New questions or discoveries: What is the implication of using different chemicals during the spraying process?
