Include images from lab but do not include images of any hand-drawn lab notes. Make sure that the font used and text sizes are consistent. Always think about how the font and text size would look on a bigger screen. Avoid using serif fonts and add a slide number to every slide Sep 05,  · The introduction of a lab report offers readers a preview of the most important details that you’ll address in the other sections of the paper. It provides a background to the work in the report and unveils the objectives of the proposed work to bring out the context of the real life application of the study outside the experiment Nov 15,  · Biology lab reports have a specific format that must be followed to present the experiment and findings in an organized manner.

This document describes a general format for lab reports that you can adapt as needed. Worse yet, each professor wants something a little different. Regardless of variations, however, how to make a lab report, the goal of lab reports remains the same: document your findings and communicate their significance. Knowing the pieces and purpose, you can adapt to the particular needs of a course or professor.

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. Bear in mind that a format, however helpful, cannot replace clear thinking and organized writing. You still need to organize your ideas carefully and express them coherently. The Title Page needs to contain the name of the experiment, the names of lab partners, and the date.

Titles should be straightforward, informative, and less than ten words i. The Abstract summarizes four essential aspects of the report: the purpose of the experiment sometimes expressed as the purpose of the reportkey findings, significance and major conclusions. The abstract often also includes a brief reference to theory or methodology, how to make a lab report.

The information should clearly enable readers to decide whether they need to read your whole report. The abstract should be one paragraph of words the how to make a lab report below is words. The Müller-Lyer illusion is the classic visual illustration of the effect of the surrounding on the perceived length of a line. The test was to determine the point of subjective equality by having subjects adjust line segments to equal the length of a standard line. Twenty-three subjects were tested in a repeated measures design with four different arrowhead angles and four line orientations.

Each condition was tested in six randomized trials. The lines to be adjusted were tipped with outward pointing arrows of varying degrees of pointedness, whereas the standard lines had inward pointing arrows of the same degree, how to make a lab report.

Results showed that line lengths were overestimated in all cases. The size of error increased with decreasing arrowhead angles. For line orientation, overestimation was greatest when the lines were horizontal. This last is contrary to our expectations. These results have important implications for human factors design applications such as graphical display interfaces.

The introduction is more narrowly focussed than the abstract. It states the objective of the experiment and provides the reader with background to the experiment. State the topic of your report clearly and concisely, in one or two sentences:. Example: The purpose of this experiment was to identify the specific element in a metal powder sample by determining its crystal structure and atomic radius. These were determined using the Debye-Sherrer powder camera method of X-ray diffraction.

A good introduction also provides whatever background theory, previous research, or formulas the reader needs to know.

Usually, an instructor does not want you to repeat the lab manual, but to show your own comprehension of the problem. If the amount of introductory material seems to be a lot, consider adding subheadings such as: Theoretical Principles or Background.

Introductions often create difficulties for students who struggle with keeping verb tenses straight. These two points should help you navigate the introduction:. Methods how to make a lab report Materials or Equipment can usually be a simple list, but make sure it is accurate and complete. Experimental Procedure describes the process in chronological order. Using clear paragraph structure, explain all steps in the order they actually happened, not as they were supposed to happen.

If your professor says you can simply state that you followed the procedure in the manual, be sure you still document occasions when you did not follow that exactly e. Results are usually dominated by calculations, tables and figures; however, you still need to state all significant results explicitly in verbal form, for example:.

Graphics need to be clear, easily read, and well labeled e. Figure 1: Input Frequency and Capacitor Value. In most cases, providing a sample calculation is sufficient in the report. Leave the remainder in an appendix.

Likewise, your raw data can be placed in an appendix, how to make a lab report. Refer to appendices as necessary, pointing out trends and identifying special features.

Discussion is the most important part of your report, because here, you show that you understand the experiment beyond the simple level of completing it. By that, they mean this is what is not readily observable. If there were differences, how can you account for them? Be specific; for example, the instruments could not measure precisely, the sample was not pure or was contaminated, or calculated values did not take account of friction. Was it avoidable? Was it a result of equipment? If an experiment was within the tolerances, you can still account for the difference from the ideal.

If the flaws result from the experimental design explain how the design might be improved. Usually you will have discussed these in the introduction. In this section move from the results to the theory. How well has the theory been illustrated? In some cases, it is legitimate to compare outcomes with classmates, not to change your answer, but to look for any anomalies between the groups and discuss those.

a circuit. Conclusion can be very short in most undergraduate laboratories. Simply state what you know now for sure, as a result of the lab:, how to make a lab report. Justify statement Might do: State significance Suggest further research Example: The Debye-Sherrer method how to make a lab report the sample material as nickel due to the measured crystal structure fcc and atomic radius approximately 0, how to make a lab report.

Notice that, after the material is identified in the example above, the how to make a lab report provides a justification. We know it is nickel because of its structure and size. This makes a sound and sufficient conclusion. Generally, this is enough; however, the conclusion might also be a place to discuss weaknesses of experimental design, what future work needs to be done to extend your conclusions, or what the implications of your conclusion are.

References include your lab manual and any outside reading you have done. Appendices typically include such elements as raw data, calculations, graphs pictures or tables that have not been included in the report itself.

Each kind of item should be contained in a separate appendix. Make sure you refer to each appendix at least once in your report.

Quick Abstract Reference Must have: Purpose Key result s Most significant point of discussion Major conclusion May Include: Brief method Brief theory Restrictions: ONE page words MAX.

Quick Results Reference How to make a lab report and Title tables and graphs Use a sentence or two to draw attention to key points in tables or graphs Provide sample calculation only State key result in sentence form. What do the results indicate clearly? What have you found? Explain what you know with certainty based on your results and draw conclusions:. What is the significance of the results? What ambiguities exist?

What questions might we raise? Find logical explanations for problems in the data:. Since none of the samples reacted to the Silver foil test, therefore sulfide, if present at all, does not exceed a concentration of approximately 0.

It is therefore unlikely that the water main pipe break was the result of sulfide-induced corrosion, how to make a lab report. Although the water samples were received on 14 Augusttesting could not be started until 10 September It is normally desirably to test as quickly as possible after sampling in order to avoid potential sample contamination. The effect of the delay is unknown.
