Go to the materials and Methods of the Annotated Sample lab Report. Results:Ý, what did you find? This is the heart of the scientific paper, in which the researcher reports the outcomes of the experiment.Ý. Report is a key word here because results should not contain any explanations of the experimental findings or in any other way interpret or draw conclusions about the data.ý results should stick to the facts as they have been observed. Generally speaking, the results begins with a succinct statement (a sentence or two) summarizing the overall findings of the experiment.Ý After that the results integrates both visual (graphs, tables, drawings) and verbal (words) representations of the data.Ý The verbal descriptions consist of series of findings. Go to the results of the Annotated Sample lab Report. Discussion: ý, what does it mean? The purpose of the discussion is to interpret your results, that is, to explain, analyze, and compare them. ÝThis is the point at which the researcher stands back from the results and talks about them within the broader context set forth in the Introduction.Ý It is perhaps the most important part of the report because it is where remember you demonstrate that you understand. The discussion section often begins by making a statement as to whether the findings in the results support or do not support the expected findings stated in the hypothesis.Ý It's important to make such a comparison because returning to the hypothesis is crucial to basic.

It provides the primary goals of the lab by:. Presenting the objective(s) for the experimental procedure (what is being done in the experiment, such as to measure something, to test something, to determine something, etc. Defining the purpose of the lab (the way the experimental procedure is linked to the learning context). It offers a hypothesis for the experimental procedure by:. Stating the hypothesis, or the best resume estimation of the outcome of the lab procedure; and.

Distilled water : This example has a list of materials at the beginning which are not necessary in the materials and methods section. The body of the section should mention the materials and equipment used during the experiment so that it is not necessary to list them in order to know what was used for the procedure. ( return to sample 2 extraneous detail : This is extraneous detail that is not needed to explain the procedure. The reader would know how to turn the blender on and off without being told that a button was pushed, and knowing that the solution smelled like potato is completely unrelated to knowing how to perform the experiment. ( return to sample 3 ) All citations from Pechenik, jan. A short guide to writing about biology. 54-102, tufts University: Harper Collins College publishers.

Now that you've hooked your reader with a good introduction, you'll start getting into the details about how you performed your study or experiment. This section should be written with enough detail that anyone would be able stenographer to follow your procedures and repeat your experiment. But make sure you don't include so much detail that it becomes overwhelming! The materials and Methods section is often the easiest part of a lab report to write because the procedure is either written in your lab manual, or you took notes on your procedure as you performed the study. Just make sure you write it in paragraph form with complete sentences, rather than just a list of your methods.

Sample 2 : A potato and shortage a knife were obtained for this experiment. Also, distilled water, a blender, cheese cloth, a clean container with a cover, and eight spectrophotometer tubes were used. A spectronic 20 spectrophotometer was used short for this experiment, as were buffers of pHs 4, 6, 7, and. Catechol substrate, parafilm coverings, kimWipes, a black pen, and pipettes were also obtained for this experiment. Finally, a pencil and pad were obtained for recording results. Sample 3 : In preparing the catecholase extract, a potato was skinned, washed, and diced. A balance was used to obtain.0 g of the diced potato.

The extract was stored in a clean, capped container. Four individually labeled spectrophotometer tubes were prepared using different amounts (as represented in Table 1) of the following reagents: a buffer of pH 7,.1 catechol substrate, and distilled water. The wavelength of the Spectronic 20 spectrophotometer was set at 540. To calibrate the specrophotometer at zero absorbance, abolitionist a blank control tube prepared with no catechol substrate and labeled "tube 1" was inverted and inserted into the spectrophotometer. It is important to note that the extract to be tested was added to each tube immediately before placing the tube into the spectrophotometer. 1.0 ml of catecholase extract was pipetted into tube. Tube 2 was immediately inverted and placed in the spectrophotometer. The absorbance was read and recorded for time zero (t0 the ten minute mark (t10 and each minute in between. Tube 2 was removed from the spectrophotometer and the same measurements were taken for tube 3 and tube 4 using the same protocol.

generally recommended that the materials and Methods section be written in past tense, in either active or passive voice. Many are written in third-person perspective but check with the professor to be certain what verb tense and perspective the report should use. This is demonstrated throughout the example of a well written Materials and Methods section. Materials and Methods examples. Sample 1 : In preparing the catecholase extract, a potato was skinned, washed, and diced. 30.0 g of the diced potato and 150 ml of distilled water were added to a kitchen blender and blended for approximately two minutes. The resulting solution was filtered through four layers of cheese cloth.

Considering the importance of "reproducible vertebrae results" in science, it is quite obvious why this second application is so vital. There are several common mistakes that are often found in the materials and Methods section of a lab report. One major concern is deciding upon the correct level of detail. 55) It is often very easy for a writer to get carried away and include every bit of information about the procedure, including extraneous information like the number of times heshe washed their hands during the experiment. A good guideline is to include only what is necessary for one recreating the experiment to know. Keeping this in mind will lead to a materials and Methods section that is thoroughly written, but without the kind of unnecessary detail that breaks the flow of the writing. Another common mistake is listing all of the materials needed for the experiment at the beginning of the section.
