It is important not to go into too many details, since there will be a part dedicated to describing the process. Experienced academic writers and instructors recommend doing the introduction at the end of your writing process, so that you could have a better idea on what the experiment includes and how the results can be achieved. This section of your work will be dedicated to the description of the materials used in the experiment and methods that helped you reach the experiment objective. Unlike the previous chapters, this section needs to be very detailed for one reason: ideally, it will be used by people willing to recreate your experiment.

Giving them as much information about the process as necessary minimizes the chances of an experimental error and helps achieve steady experimental results time after time. You also need to provide information on how exactly and at which stage of the experiment they were used. Alternatively, you can make notes as you conduct the experiment and then refer to those notes when you are listing the materials and methods. This chapter is arguably the most important one in the scientific concept. The way you showcase the results largely depends on the subject and the nature of the experiment. The one thing that should always be present in this section is a written summary of the results. If you have discovered any patterns or trends when conducting the experiment, be sure to also include them in your summary.

In most lab reports you will also find some graphs, charts, and tables. Sometimes they are simply a more convenient way to display the results but in some cases they are simply indispensable. To make your writing results more visible, you can add at least one graph or table even if you have successfully listed the results in written form. In this chapter, you will lay the grounds for further scientific discussion and its results. Start by evaluating the experiment itself. How successful was the organization of the experiment?

Is there anything you would have done differently if you received a second chance to launch the experiment? Were there any materials and tools missing from the experiment? Once you answer those questions in sufficient detail, you can move on to the discussion of the results. How successful were you in meeting the objectives of the experiment? Has your hypothesis proven to be correct or does it need further investigation? Did any errors prevent you from obtaining the expected results? Finally, to end this chapter on a discussion note, make a few suggestions for the people who think of recreating your experiment.

Tell them what they can change in the process or which additional tools they can use to improve the results. If there is any relevant scientific information they can study to make the experiment more effective and the procedure clearer, make sure to recommend those sources. Here you can also make suggestions for future experiments in the field. It may be helpful to provide a figure to diagram your experimental setup. Numerical data obtained from your procedure usually presented as a table. Data encompasses what you recorded when you conducted the experiment. It's just the facts, not any interpretation of what they mean. Describe in words what the data means. Sometimes the Results section is combined with the Discussion.

The Data section contains numbers; the Analysis section contains any calculations you made based on those numbers. This is where you interpret the data and determine whether or not a hypothesis was accepted. This is also where you would discuss any mistakes you might have made while conducting the investigation. You may wish to describe ways the study might have been improved. Most of the time the conclusion is a single paragraph that sums up what happened in the experiment, whether your hypothesis was accepted or rejected, and what this means. Graphs and figures must both be labeled with a descriptive title.

Label the axes on a graph, being sure to include units of measurement. The independent variable is on the X-axis, the dependent variable the one you are measuring is on the Y-axis. Be sure to refer to figures and graphs in the text of your report: the first figure is Figure 1, the second figure is Figure 2, etc. If your research was based on someone else's work or if you cited facts that require documentation, then you should list these references.

The conclusion section is where you summarise your report. A conclusion is usually one paragraph or to words. In this way a conclusion is very similar to an abstract, but with more emphasis on the results and discussion. A conclusion never introduces any new ideas or results. Rather, it provides a concise summary of those which have already been presented in the report. When writing a conclusion you should:. When in-text citations are incorporated into your lab report typically in the introduction or discussion you must always have the full references included in a separate reference list. The reference list is a separate section that comes after your conclusion and before any appendices.

Check your lab manual or unit information to determine which referencing style is preferred. Carefully follow that referencing style for your in-text references and reference list. You can find examples and information about common referencing styles in the Citing and referencing Library guide. The following is an example of a reference list based on the in-text citations used in the Introduction and Conclusion sections in this tutorial. This example has been formatted in accordance with the CSIRO referencing style. Jones T, Smith K, Nguyen P, di Alberto P Effects of habitat overlap on population sampling.

A science lab report is a structured way of communicating the outcomes of your practical work. The structure of a typical lab report includes the following sections: Aim and Hypothesis - Why you conducted the practical work. Method - How you conducted the practical work and how any data processed. Results - What was the data, process or product obtained from the practical work. Discussion - How your results addressed your aim and hypothesis. Conclusion - What was the overall outcome of your practical work and how do your finding relate to the larger body of scientific knowledge. View Close. Check for discipline-specific requirements.

Lab reports can vary in length and format. These range from a form to fill in and submit before leaving the lab, to a formal written report. Keep notes in a dedicated lab notebook. Please note that many units require students to record notes and observations in logbooks in the laboratory. These have their own purpose and conventions and are different from lab reports. Do not copy material directly from your lab instructions. Lab instructions provided by your teachers are NOT in the style of a laboratory report. Use a passive voice in your writing. Also, write using the past tense. Title The title describes the purpose of the practical work in precise terms. Addressing each question only requires one to two sentences: Why was the experiment conducted? What results were obtained? What do these results mean?

How do the results answer the overall question or improve our understanding of the problem? Shorter lab reports may not require an abstract, so check your guidelines first. Turn lab instructions into a lab report method A common mistake students make is copying the instructions their teachers provide directly into their method section. A typical set of instructions usually includes: How the apparatus and equipment were set up e. experimental set-up , usually including a diagram. A list of materials used. Steps used to collect the data.

Any experimental difficulties encountered and how they were resolved or worked around. Lab instructions Use a clean pipette to measure 25ml of HCl aq into a ml conical flask. Rinse a burette with standardised NaOH aq and clamp it to the retort stand as shown Figure 2. Fill the burette to the 0.

Writing a chemistry lab report can be challenging, but it is definitely a skill that can be learned. In order to write a good lab report for chemistry experiments, you must first understand the purpose of the report. A lab report is not just a summary of what you did in the lab, it is also a tool that instructors can use to assess your understanding of the material. Lab reports should be written in a clear and concise manner. It is important to remember that the reader of your report will not have the same level of knowledge as you do about the subject.

Therefore, it is important to explain all terms and concepts in a simple and straightforward way. The format of a chemistry lab report may vary depending on the instructor, but there are some general elements that are always included. Your report should be divided into sections, with each section starting on a new page. The following is an example of how to format a chemistry lab report:. A chemistry lab report is a written report describing your findings from conducting chemical experiments. The purpose of a chem lab report is to communicate your results to your instructor and to other students in the class. Lab reports are an essential part of scientific training, providing valuable communication skills that will be useful throughout your chemistry career.

There are many different ways to write a chemistry lab report, but here are a few general guidelines that will help you get started:. The title page should include the title of your experiment, your name, and the names of any other collaborators. The abstract is a brief summary of your experiment. It should include the purpose of your experiment, the methods you used, the results you obtained, and your conclusions. The purpose of this experiment was to synthesize aspirin and measure its melting point. The synthesis was carried out using two different methods, and the melting points of the products were measured. The results showed that the synthesis using method A produced a product with a higher melting point than the product synthesized using method B.

The introduction should provide a brief overview of the purpose of your experiment and the methods you used. You should also state the hypothesis you were testing and explain how you went about proving or disproving it. Most students keep on wondering how to write an introduction for a lab report chemistry. The truth is that this part of your report should be quite easy to write, as long as you keep in mind a few key elements. The methods section should describe the procedures you used in your chem experiment. This includes describing how you mixed your solutions, what equipment you used, and any other relevant details. You should also explain why you chose these particular methods and how they helped you answer your hypothesis.

You should also list the materials you used in your lab, including the chemicals and equipment. Be sure to include the name and quantity of each material. For example: 3 ml HCl, 1 ml NaOH aq , Phenolphthalein indicator, mL Erlenmeyer flask, Bunsen burner, etc. The results section is where you get to report the data from your experiment. This includes things like measurements, observations, and any other relevant information. Be sure to present your data in a clear and concise manner, and be sure to include a discussion of any trends or patterns you may have noticed. In the discussion section, you should interpret your results and discuss their implications. The discussion section is where you interpret your findings and explain what they mean.

You should also identify any areas that need further research. When writing the discussion section of a lab report chemistry, it is important to remember that you are not simply recounting what happened during the experiment. Rather, you are providing an interpretation of the data and explaining its significance. The conclusion should summarize the findings of your report and highlight the most important points. It should also provide a brief overview of the methods you used and discuss any possible errors or limitations of your experiment. A good conclusion will leave the reader with a clear understanding of the purpose of your experiment and the significance of your findings. It should also provide a concise summary of the methods you used and the results you obtained.

The references section should list any sources you used in your report, including books, articles, websites, and lab manuals. Be sure to include all relevant information, such as author names, publication dates, and URLs. When writing a lab report for chemistry, it is important to include a references section so that readers can easily find the sources you used. This is especially important if you are using sources that are not commonly known or if you are citing sources that are not available online. By following these general guidelines will help you write a clear effective chemistry lab report. However, always check with your instructor for specific guidelines that may be applicable to your particular course.
