The instructions for analyzing data for most labs will not be as detailed as the instructions below. A sample lab report for this activity is provided as an example for you to follow when writing future lab reports. In this investigation, we examined the hypothesis that the circumference C and diameter D of a circle are directly proportional. We measured the circumference and diameter of five circular objects ranging from 2 cm to 7 cm in diameter. Vernier calipers were used to measure the diameter of each object, and a piece of paper was wrapped around each cylinder to deterimine its circumference.
Graphical analysis lead to a less precise but equivalent estimate of 3. However, only a narrow range of circle sizes were analyzed, so additional data should be taken to investigate whether the constant ratio hypothesis applies to very large and very small circles. Five objects were chosen such that measurements of their circumference and diameter could be obtained easily and would be reproducible. Therefore, we did not use irregularly shaped objects or ones that could be deformed when measured. The diameter of each of the 5 objects was measured with either the ruler or caliper. The circumference and diameter of each object was measured with the same measuring device in case the two instruments were not calibrated the same.
The circumference measurement was obtained by tightly wrapping a small piece of paper around the object, marking the circumference on the paper with a pencil, and measuring this distance with the ruler or caliper. The precision of the ratio can be estimated using the error propogation formula:. This should include a list of all materials used, a diagram of the lab setup if appropriate, and the steps taken to accomplish the lab paragraphs preferred, but organized, ordered lists of instructions are acceptable with list items in complete sentences. Put your data into tables and graphs which are appropriately labeled and explained.
Review your tables and graphs to determine the key findings from the lab exercise. Write a paragraph explaining each table and graph including its key result and other salient details. Arrange the results section in an organized fashion. The key relationship from each table or graph is described in a separate paragraph with appropriate supporting details. How far off were your results from the theory? error calculations come in handy here, they give you a quantitative measure of how well your theory was matched. Give reasons why the theory and experiment did or did not match. These reasons may be due to physics, incomplete assumptions, or they may be from procedure see error analysis below.
Summarize your error analysis. This is where you discuss what may have caused your errors. Some types of error include see your lab manual for more information on these and other types of errors : Scale Limitation Uncertainty, Parallax, Random Errors, and Systematic Errors If required, do not forget the propagation of error through your calculations! You need to be able to say how confident you are in your result. Make sure that the reason you are stating as the cause of your error predicts whether your results will be too high or too low. This section is usually dominated by calculations, tables and figures; however, you still need to state all significant results explicitly in verbal form.
In most cases, providing a sample calculation is sufficient in the report. Leave the remainder in an appendix. Likewise, your raw data raw data sheet from Lab Manual should be signed by instructor at the end of Lab experiment should be placed in an appendix. Skip to main content area.

A well written measurement log is essential if you later want to remember what was measured and what happened during the measurement. Therefore it is necessary to write down all things affecting the measurement carefully and accurately. The notes should be made continuously during the measurement as the details are quickly forgotten. You can't make too many notes. The measured values must be written down as the are, i. without making any calculations. It should be noted that when using a computer in the measurement, a log file created by a computer program, while useful, is never a substitute for a log book written by the student. Of course the log book can be written with a computer as well as with paper and pen. The report is an essential part of completing the laboratory exercises. Unless otherwise stated, a certain form of the report is required in all the laboratory exercises.
It is not necessary to follow it rigidly in all the details, but the general structure must be adhered to. The reason for limiting the artistic freedom of the students is to learn the format of international research reports. The instructions that follow are mainly based on the practices of European Physics Journal and Physical Review Examples of articles published by the research groups of the Department of Physics have been collected on the wall of the student lab. These will give an idea of the format behind the one used in the lab reports. Research reports published in international journals are read in four levels.
The first and most important part in selecting the readers is the title. It should describe the research topic with sufficient accuracy. Most people finding the title interesting read only the abstract, where the methods and results of the research are presented very shortly. Most of the readers who, based on the abstract, decide to go further into the work, usually glance through the pictures and tables, and possibly the conclusions. Finally only very few will read the full article. It follows from the previous that a good scientific writer is able to pack a lot of information to these key areas. Special care should be dedicated to the captions for pictures and tables. The lab report is not written for the evaluator. Especially the attitude "surely the evaluator understands this The report, as a scientific article, is written for a group of equals.
In the case of research report the group will consist of other researchers in the field. For students the equal group is other students attending the same course. In the case of research report many things can be assumed known to the readers. In the lab report one should be careful with these assumptions. The previous will also be taken into account by the evaluator. A report written in this way also gives the evaluator a clearer picture of what has been learned and what needs to be clarified. NOTE 2: If someone insists on writing the entire report by hand, the use of pencil is also not accepted.
Using computers in writing is strongly recommended. See the picture below for the correct format of the cover page. An email address is mandatory get it if you don't already have one. Phone number is not required, but can be included. Always write your full name, because there may very well be other people who have the same name. Including your date of birth is necessary only if there is another person in the university with exactly the same name as you you'll probably find this out the first time an evaluator attempts to register your grade.
Never write your personal ID number!! After the contact information the correct code and name of the work are written. Beneath this are the measurement date and the full name of the demonstrator the assistant on shift when you did the measurement. The names can be found on the finnish web pages or by asking during the shift. The abstract maximum words is at the bottom of the page. The abstract must include the goal of the work, the main results with error estimates and the most important conclusions. Do not include tables or pictures in the abstract! The physical phenomena related to the work are presented. Also a brief historical survey can be included.
One should also describe how the work relates to physics or science in general. If the report is very long or complicated, it might be a good idea to explain it's structure in the introduction. In reports following a predetermined format this is a better way than a simple contents list. In relatively short reports this is not necessary. In this chapter the theory relevant to the work is presented. Sometimes it can be short enough to be included in the introduction but not vice versa, i. a chapter titled "Introduction" should always be found on the report. The relevant formulas are presented and numbered so that they can later when doing the calculations be referred to.
Also the formulas derived for error estimates can be placed here or in an attachment. When using sources other than the instruction sheet the references must be included in the text. The symbols used and their meaning must be explained. The basic mathematical operators are assumed to be known, but for instance p can be either pressure or momentum. Avoid having more than one meaning for the same symbol in your report - unless the difference is always trivially clear from the context. Write the theory section as well as other sections in your own words. Best grade for this section is given when the presentation is based on your own expertise or on literature with proper references.
The laboratory work instruction sheet can be used as a basis of the presentation, but this yields a lower grate. Never copy text from the lab work instruction sheet or other reference. The measurement apparatus and the methods are described in detail. In principle it should be possible to duplicate the measurement using the information presented here. In scientific reports the models of the meters etc. are not usually included, but in lab reports this information should be presented. The equipment used in scientific research are typically so complicated that their detailed descriptions are presented in special publications, which can later be referred to.
There are journals specialized in this kind of reports, for instance Nuclear Instruments and Methdods NIM A. Use pictures to clarify the text. Also present relevant circuit diagrams. While the use of possibly unclear pictures from the instruction sheets is allowed, drawing preferably clearer pictures is encouraged. Straightforward copying of the text from the instruction sheets is strictly forbidden. In this section the results and the calculation leading to them are presented. The use of pictures and tables is highly recommended! Both the pictures and the tables must be numbered. The pictures are numbered with arabic numbers i.
Figure 1,2,3, Tables can be numbered either with arabic or roman numbers there is some variation in scientific journals: for instance European Physical Journal uses arabic and Physical Review roman numbers. For pictures the captions are located below and for tables above. Table I. Simple rules of writing Adapted from American Physical Society News, June , page 7. Tables can also be used to present other than numerical information. It is common practise to number a picture or a table even in the case that there is only one. If the measurement log is already in a tabular format, repeating it in the text is usually not necessary. However, tabulating the final and possibly the intermediate results is often useful.
Every picture must have a caption and be numbered. Also graphs must be easy to read: they must be big enough, the axis must be labeled with large enough font , the symbols are clear and error bars are included when practical. The use of clarifying texts in the pictures is allowed and encouraged. Pictures or tables too large to be inserted in the text can be put as attachments. The rules outlined above hold also for these pictures and tables. In some instruction sheets it is asked to draw this or that on millimeter-paper or the like. This is a remnant from the good old days. While this can be followed literally millimeter-paper is available in the lab nowadays it is more convenient to use a suitable computer program.
The popular Excel has some limitations in drawing pictures and fitting functions, but with some effort reasonable results can be obtained. Origin and Gnuplot, which are installed in the computer-class machines, produce clean pictures quite easily and include goof fitting libraries. The computer-class machines also have DataStudio, which is licensed to the Department of Physics. The license allows students to copy the program to their own machines.

Physics Lab Report Examples We will look at some examples of the different parts of a lab report to get an understanding of how best to lay out a report. There the results are evaluated and compared to theoretical or other experimental values. Merely recording the expected and observed results is not sufficient; you should also identify how and why differences occurred, explain how they affected your experiment, and show your understanding of the principles the experiment was designed to examine. Categories: Science Writing Physics. a chapter titled "Introduction" should always be found on the report.
Conclusion Simply state what you know now for sure, as a result of the lab. The next will be [2] and so on, how to write physics lab report. Sign up to highlight and take notes.
