In discussing the results, you should not only analyze the results, but also discuss the implications of those results. Moreover, pay attention to the errors that existed in the experiment, both where they originated and what their significance is for interpreting the the reliability of conclusions. One important way to present numerical results is to show them in graphs. (See a sample "Results and Discussion" section .) In longer laboratory reports, a "Conclusion" section often appears. Whereas the "Results and Discussion" section has discussed the results individually informatics essay, the "Conclusion" section discusses the results in the context of the entire experiment. Usually, the objectives mentioned in the "Introduction" are examined to determined whether the experiment succeeded. If the objectives were not met, you should analyze why the results were not as predicted. Note that in shorter reports or in reports where "Discussion" is a separate section from "Results," you often do not have a "Conclusion" section. (See a sample "Conclusions" section .) The potentiometer measured voltage versus time for the masses as they dropped, but the measurement of interest to us was position versus time. For that reason, a 'calibration' was performed before we measured any data. In the calibration easy argumentative paper topics, the potentiometer's initial voltage was measured. Then the string was pulled a set distance (2 inches), and the voltage was recorded. This process of pulling the string a set distance and recording the voltage continued another two times (see Appendix A for the results). To determine the relationship between voltage and position, the differences in the voltages were averaged and divided by the length. The resulting relationship was 0.9661 volts/inch. The heart of a laboratory report is the presentation of the results and the discussion of those results. In some formats, "Results" and "Discussion" appear as separate sections. However, P.B. Medawar [1979] makes a strong case that the two should appear together, particularly when you have many results to present (otherwise, the audience is faced with a "dump" of information that is impossible to synthesize). Much here depends upon your experiment and the purpose of your laboratory report. Therefore examples of critical thinking at work, pay attention to what your laboratory instructor requests. Also, use your judgment. For instance, combine these sections when the discussion of your first result is needed to understand your second result essay on attitude, but separate these sections when it is useful to discuss the results as a whole after all results are reported. The abstract should be written concisely in normal rather than highly abbreviated English. The author should assume that the reader has some knowledge of the subject but has not read the paper. Thus, the abstract should be intelligible and complete in itself; particularly it should not cite figures, tables, or sections of the paper. The opening sentence or two should, in general, indicate the subjects dealt with in the paper and should state the objectives of the investigation. It is also desirable to describe the treatment by one or more such terms as brief, exhaustive, theoretical, experimental, and so forth. The test performed on the potentiometer was accomplished by winding a string around the potentiometer shaft, attaching a mass to the string, and letting the mass fall. The change in resistance of the potentiometer with time indicated the acceleration of the mass. In this experiment it was assumed that the constant Coulomb friction torque was the only friction affecting the potentiometer. If this assumption were true critical thinking classes in schools, the friction force from the torque would be F f = T/r (where T is the torque and r is the radius of the potentiometer's shaft). Likewise, the gravity force would be F g = mg (where m is the mass tied to the string and g is the gravitational acceleration). A force balance then gives * Write a possible solution for the problem. * This section should include any data tables, observations how to write a thesis statement for essay high school, or additional notes you make during the lab. The abstract is a one or two paragraph concise, yet detailed summary of the report. It should contain these four elements: The discussion section should explain to the reader the significance of the results and give a detailed account of what happened in the experiment. Evaluate what happened, based on the hypothesis and purpose of the experiment. If the results contained errors, analyze the reasons for the errors. The discussion should contain: Now that you have completed an experiment and have collected all of the necessary information in your lab notebook and any supplementary data from analytical instrucments, you need to write up your results in a lab report. The purpose of writing reports you've performed is to communicate exactly what occured in an experiment or observation and to clearly discuss the results. What you did: Reiterate your procedures briefly (including any changes you made). (A Former UCLA First-Year Lab Courses Teaching Assistant) Other procedures or theory: If you need to elaborate on some of the techniques you stated in your goal (or couldn't state in your goal), you can write a couple more sentences about them afterwards. Or you can add anything else that you might think is relevant, like additional major procedural steps you will take.
This part of the pre-lab should take no more than one page. A good flowchart should give a reader an immediate idea of what's need to be done in the laboratory except in a less detailed format. Think of a flowchart as a "road map" of the experiment. It gives a reader a "pictorial" representation of the experimental procedure. In general there are two major steps when constructing the flowchart. First, read the experimental procedure carefully. Second, rewrite the procedures in a flowchart format. Keep in mind that the flowchart should be brief and cover all the steps in a simple and easy to follow manner. There should be no complicated sentences or paragraphs in the flowchart. You will have to do a lot of rewriting in order to simplify the procedures into a flowchart format. This is exactly why we want you to do it. This gives you a chance to THINK about what you read and how to rewrite it in a way that can be implemented into a flowchart.
A lab report is more than just something you turn in to (hopefully) get a good grade. It's your opportunity to show that you understand what is going on in the experiment paper you can write on online, which is really the most important part of doing it. In addition, I think it's actually very good practice for getting across your thoughts about the science you are doing in a manner that the reader can understand.
