The text should also act as a link to the discussion section, highlighting any correlations and findings and leaving plenty of open questions. Quite often the individuals piecing together laboratory reports include a clear indication of the methodologies or theoretical work that has been put into practice. You must call the reader's attention to these trends or they may be missed. Next, write the summary text to support your illustrative materials. Results are analyzed in terms of the hypotheses being tested, variables chosen,and tests performed. Ý Titles are especially important to scientists because articles are typically indexed according to key words that come from the title.
Since you'll be talking about your own interpretation of the results in the discussion section, you need to be sure that the information reported in the results section justifies your claims. Introduction Your introduction should include basic background information relevant to the experiments you did. Upon returning and observing the streak plate, there was an abundance of green across the plate. It is not a bibliography a list of the books you used. A short guide to writing about Biology. The second test performed was a Urea Test which also gave a clear positive result confirming that unknown gram positive bacteria as Staphylococcus epidermidis because Staphylococcus aureus gives a negative result.
A nitrate test was performed in order to detect if the bacteria was able to reduce nitrate into nitrate or some further reduced form. The text, conversely, is used to direct the reader to those, also clarifying any unclear points. Ý It's important, then, to be specific, providing details of what you have learned about the theory or principle or procedure at the center of the lab. Discussion:Ý What does it mean? Structure your results section around or figures that summarize the results of your statistical analysis. In fact, the wise writer uses graphs and figures to highlight the most important or interesting information.
Record all data in your lab notebook and clean up. Coli as the colony sizes were near maximum of the standard result. Ý The learning context provides a way for you to situate the lab report within the overall purpose for doing the lab in the first place:Ý to learn something about the science of the course you are taking. Correcting for our water results this made our measurements —15. Give a brief understanding of its background. Methods for Presenting Data The ways of presenting data vary depending upon what you want to present to the reader.
Remember that in most laboratory reports where the Discussion and Results sections are displayed separately one does not often encounter a conclusion. You should seek information from your lecturers and tutors about whether this is appropriate in your discipline. While there is still room for error in our results due to the change in boiling and melting points as a function of atmospheric pressure this difference should be very small. Then a urea test was performed to check for the production of urease. Ý It's necessary, then, that titles be fully informative about the content of the report. Student Chemistry 1 Identification of a Compound using Melting and Boiling Points Introduction One of the primary methods used to characterize a new compound is the physical determination of its normal melting and boiling points.
Each table should be given a number and a title. Example A Example B Results On observation of each strain of E. . Avoid repeating information, unless the information is expanded to provide additional insight. As can be seen from our water data the experimental values for the melting and boiling points of water differed from the theoretical values by +0.
Centers for Disease Control and Prevention, 02 Apr. When you have finished all the sections, rearrange them in the proper order to turn in to your teacher: Title, Abstract, Introduction, Methods, Results, Discussion, Conclusion, and References if it is assigned. Tables 1 and 2 lists the tests, purposes, reagents used and the results of each test. The absorbance values mean nothing if the reader doesn't know at what level they were taken, and what does protein mean in the third column? Simply relay the data in the most objective and straightforward way possible. The Parts of a Laboratory Report Introduction:Ý What is the context in which the experiment takes place? This identification was reached by only one biochemical test and close observation. Your style should be brief, but not using note form.
So your lab report will have all the sections—Introduction, Methods, Results, Discussion, Conclusion—but with only a sentence or two in the sections that were not assigned. Results: The results section of a paper usually present the descriptive statistics followed by inferential statistics. This belongs in the section. While doing so, it is crucial to have a realistic approach towards the initial hypothesis, results obtained, experiment expectations and methods used to get their results. This section is often the shortest part of your paper, and in most cases, the most clinical. If you are in doubt about how much to include, you can always insert your raw data into the appendix section, allowing others to follow your calculations from the start.
If you used a software program capable of generating results for you, use that to create figures according to variables. Make sure the results are presented clearly and concisely. How to reference this article: McLeod, S. Abstract: you write this last The abstract comes at the beginning of your report but is written at the end. By documenting each of these steps in a clear and concise manner, it allows one to follow along while also being able to repeat the experiment if necessary. Consistently patrons tends to make distinctive shop for any instantaneous.
Mention implications of your findings if appropriate. The results you collect will most likely contain a story that you want to tell to the reader in an interesting manner. Title Give your lab report a title. For more help on writing an Abstract,. Ý This is important because it helps you to understand the value of the lab and convinces the reader that the lab has been a success. Always assume that your readers have a solid understanding of statistical concepts. Try to distill the important steps and variables from all the details.
