How To Write A Good Lab Conclusion In Science (with Free Sample)

A lab report describes an entire experiment from start to finish, describing procedures, reporting results and analyzing data. The report is used to demonstrate what has been learned. 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. Demonstrate that you’ve effectively learned the objectives of your assignment by writing a solid conclusion to your lab report. Review your assignment. Verify that you’ve accomplished all the parts of your assignment so that you can properly address them in the conclusion. Take a few moments to make a list of what you’re supposed to demonstrate or learn in the experiment. ] This is a good tactic to help you brainstorm exactly what you’d like to say in your conclusion. Use the RERUN method. Start mapping out the different elements of your conclusion by using the RERUN method. ] RERUN stands for: – Restate: Restate the lab experiment.

Explain: Explain the purpose of the lab. 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 impacted the experiment. New: Discuss new questions or discoveries that emerged from the experiment. Plan other sections to add. The RERUN method is a good start, but there may be other components that you should include. It’s a good idea to talk about what you’ve learned in 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. Introduce the experiment in your conclusion. Start out the conclusion by providing a brief overview of the experiment. Describe the experiment in 1-2 sentences and discuss the objective of the experiment.

Also make sure to include your manipulated, controlled and responding variables. Restate your procedures. Give a brief summary of the process that you went through with your experiment. Give an overview of the experiment, which will help the reader visualize what you did. ] – 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. Briefly describe what you discovered. In a few sentences, summarize the results that you arrived at in your experiment. You don’t need to give the raw data here. Comment on whether or not your hypothesis is supported. ] The hypothesis forms the basis of your experiment and drives the parts of your process. Restate your hypothesis and then state clearly and concisely whether or not your hypothesis has been supported by the experiment.

Was the experiment a success? Link your results to your hypothesis. The results of your experiment have determined whether or not the hypothesis is supported. ] Clarify why the results indicate a supported hypothesis or not. Describe what you learned in the lab. You may be asked to demonstrate a particular scientific principle or theory. Add details about what you learned and how you learned it. ] Give specifics about how you learned that molecules will act in a particular environment, for example. Answer specific questions given in the assignment. Your teacher may have listed certain questions in the assignment that need to be answered. On a new line, write the question in italics. Explain whether you achieved the experiment’s objectives. The introduction to your lab report should have stated certain objectives that you hoped to achieve with this experiment. ] – If your experiment did not achieve the objectives, explain or speculate why not. Describe possible errors that may have occurred. To provide an accurate depiction of the lab experiment, describe errors that may have happened in the course of the experiment.
