Mistakes to Avoid When Writing a Lab Report - Florida News Times
The Laboratory Report 1,2. The research paper is the primary means of communication in science. The research paper presents the results of the experiment and interpretation of the data, describes the rationale and design of the experiment, laboratory report writing, provides a context for the results in terms of previous findings and assesses the overall success laboratory report writing the experiment s.
Scientists working in industrial laboratories do not write as many journal articles as their colleagues in academia, laboratory report writing, but they routinely write progress reports, which take laboratory report writing same form as a journal article, laboratory report writing. So no matter what your career goals are, it is important that you become familiar with this style of writing.
There are set rules for preparing a journal article or a laboratory report. The style requirements vary only slightly from journal to journal, but there are far more similarities than differences in the scientific writing style. There are several style guides 3, 4 and articles 5 to help scientists and students prepare their manuscripts.
Because of the variation in journal styles, and the requirements for a specific course, your instructor will inform you of specific style requirements for his or her class. This guide is based on the Journal of the American Chemical Society style, 6 and is meant to provide a good starting point for writing a laboratory report. It is not meant to be the definitive style guide; you must adjust your style to your audience and the journal in which your results laboratory report writing be published.
General Editorial Issues. How your paper appears to the journal editor or reviewer is their first impression of your science, and it will color their impression of your results, if you let it. Remember that everyone will assume that if you did not take the time to write your paper carefully, you did not take the time to do your science carefully.
The following are some general editorial guidelines to follow that will leave a good first impression with your readers, laboratory report writing. General Stylistic Issues. Uniformity of style is the key to scientific communication.
The journal editors, the referees who review a laboratory report writing, and the journal readers who are interested in the results presented in a paper all expect certain things to be present in a manuscript and that they are in a certain order. Just like the sloppy-looking paper, a paper that does not adhere to the expected style reflects poorly on the author, laboratory report writing, no matter how good the science is.
In laboratory report writing last example we assumed that the author whose name is starred is the principle investigator on the project, and gave them more credit for the work. Note that it is an American convention to list the principle investigators last, while many European and Japanese journals place them first.
Often there are two principle investigators, and in this case both should be mentioned. For example, the work by Jackson, A.
If there are more than two principle investigators, it is best to use either of the formats given in example a or bor to use some other wording to avoid this construction entirely. Sections should appear in your paper in the order described below. All sections but the title have the section explicitly labeled, usually in bold letters to differentiate it from the rest of the text, and left aligned on the page.
A blank line should appear after the last word of the section to separate the various sections, but a line should not be placed after the section title. Please note that you should not physically assemble your paper laboratory report writing this order. Instead, laboratory report writing, it is suggested that you compose: a Materials and Methods, b Figures, Figure Legends and Tables, c Results, d Discussion, e Conclusions, f Introduction and Schemes, g Abstract, and h Title.
Then put all the sections together in the final paper in the order outlined above. A template is available to help laboratory report writing organize your report. Click here to learn more about it, laboratory report writing. It may be helpful to organize sections further into subsections. These subsections should have their own titles that are italicized and followed by a period. A title reflects the emphasis and contents of the paper.
Therefore, it is not uncommon for the title to reveal the results or major conclusions of the experiment, laboratory report writing. Examples are given below. The title should be on its own page the title pageleft-aligned at the top of the page, in bold letters. The title must be brief 2 lines maximum and grammatically correct.
Under the title, write your name and your professional address in italics Department of Chemistry, Truman State University, East Normal, Kirksville, MO The abstract is a one-paragraph summary of the paper that is written in the present laboratory report writing. As the abstract is the only part of the paper that is entered into article databases, it should be able to stand alone, separate from the paper.
The first one to three sentences of the abstract should briefly introduce the reader to the problem studied. Next, the scientific approach, major results and primary significance of the findings should be presented. The abstract is generally words less for shorter papers. This section is normally written after the body of the paper. Because the abstract is separate from the paper, all abbreviations should be written out, or defined, and any references should be written out in full.
An example of how a reference might appear in an abstract is. Note that in some journals that inclusion of the title in a reference is not required vide infra, laboratory report writing. The introduction should present the scientific problem at hand to the reader, laboratory report writing. Explain to the reader why the experiment was conducted, how it was designed and perhaps, if appropriate, what was found.
Literature that is relevant should be incorporated and will help the reader understand the context of your study. A good rule of thumb is to start at the most general topic and progressively move towards the specific. Here is a general outline for an introduction:. In this section, consider including figures, schemes and equations that complement the text. While this is similar to the information that you should have written your notebook, the introduction to a paper is different than the background that you included for an experiment or experiments in your notebook.
Remember that you are trying to reach a larger, more general audience with your paper, and the introduction must be structured to draw the reader in and help them focus on your important results. The experimental section of your paper should be a logical, coherent recount of the experiment s conducted.
This section should be complete enough for a trained scientist to pick up your report and replicate your experiment. The experimental section in a laboratory report is more concise than the corresponding section in the laboratory notebook. It should not be a step-by-step procedure of the activities carried out during the laboratory period.
The first paragraph of the experimental section contains information on key chemicals used in the procedure. When the chemicals are used as received, there will usually be a statement to that effect and further details are not usually necessary. Do not list lot numbers. If a starting material was synthesized according to a literature procedure, then state this in the opening paragraph and reference the procedure. If purification or drying of the compounds is required, it is described here, also.
The first paragraph often will also list the instruments used to characterize the newly synthesized substances. All instruments and equipment should be specified including the model number of the instrument and the name of the manufacturer serial numbers are not included.
When a spectroscopic or physical method is laboratory report writing focus of the report, it will be described in its own subsection. You are not required to write the experimental in this fashion. For common techniques, laboratory textbooks should be referenced, laboratory report writing. However, if a previously published procedure was modified, laboratory report writing, then this is stated and only the modifications performed are included.
If the procedure is your own, then outline the procedure with the main points, laboratory report writing, including details that are critical to replicating the experiment. These might include the type and size of your HPLC column, the buffer or the concentrations of chemicals. When the syntheses laboratory report writing substances are reported, the synthetic procedure used to make each substance is described in its own separate paragraph.
The paragraph begins with the name of substance, or its abbreviation if the abbreviation was defined earlier in the paperin bold face.
If numbers are assigned to the compounds, these are also included in parentheses. Often the synthesis will be written out, even when a literature procedure was followed. The mass and percent yields must be reported. These include: melting point range and literature value, if knownelemental analysis both calculated and foundselected peaks from the mass laboratory report writing with assignmentsselected IR peaks also with assignmentsand any NMR peaks with their chemical shift, multiplicity and integration you will often find the observed coupling quoted and the assignment of the peaks.
The experimental section has two quirky wrinkles on the general scientific style. These are:. In the Results section, the results are presented and summarized in a reader-friendly form. Raw data are not presented here. For instance, it is appropriate to include the average calculated concentration of a solution but not the original absorbance values that were collected from the spectrophotometer; that information is best left in your laboratory notebook.
Graphs and tables often make the data easier to interpret and more understandable click here to review graph preparation, laboratory report writing. A graph is presented in the paper as a figure. In general, a graph or table is an appropriate representation of the data when more than 2 or 3 numbers are presented. Data that are presented in the form laboratory report writing a graph or table should be referred to but should not be repeated verbatim in the text as this defeats the purpose of a graph.
More information on figures and tables is presented later. Observation of trends in the numerical data is acceptable. However, interpretation of the trend should be saved for the Discussion section. Remember, do not simply report your numerical results. The Results section must have a narrative that describes your results. This narrative can include a description of the data such as spectra or data in graphswhat problems were encountered during data acquisition and how they were resolved, or not and a general description of how the raw data were processed to give the final results not a step-by-step description of everything you did.
The reader wants to know what you did, how you did it, what problems you encountered and finally what your results were.
Each of these topics must be addressed in the Results section in a way that is clear, yet concise. This is the section where the results are interpreted.
This section of the paper is analogous to a debate, laboratory report writing.
