The seedling growth was measured from the base of the stem to the top of the stem, excluding leaf length. The two tests call for the bacterium to be in a liquid form when added to the test tubes, but the test was done from the bacterium being on an agar jell. Your instructor may require you to do this in a paragraph or a list form. One reason for using this format is that it is a means of efficiently communicating scientific findings to the broad community of scientists in a uniform manner. You don't want to plagiarize the work of others. Describe how they affected your experiment.
We are used to reading about events in a chronological way, and so your readers will likely comprehend what you did if you relate that information in the same way. Then inclusion, and exclusion criteria, and if used control group, and its characteristics should be documented. Headings : Each Appendix should be identified by a Roman numeral in sequence, e.

It is generally known that the material and methods section is a relatively easy section of an article to write. It should be noted that a well-written materials and methods section markedly enhances the chances of an article being published. Here is a concrete example which demonstrates how important reproducibility is. For the spontaneous generation hypothesis all trials should include sterilized conditions. In these cases the procedure of monitorization should be documented for the sake of the validity of the study in question.

On the other hand, since pragmatically speaking you are also writing for your teacher who is seeking to evaluate how well you understand the principles of the experiment , articulating the rationale demonstrates that you comprehend the reasons for conducting the experiment in that way and that you are not just following instructions. A sample was taken from this colony and transferred to a nutrient broth agar to further isolate it. Generally speaking, the Results begins with a succinct statement a sentence or two summarizing the overall findings of the experiment. Try to avoid unpasteurized dairy products. Amoebas do not seem to have a particular shape, with the exception of the pseudopodia that consistently protrude from the cell.
In the present study, systemic functional linguistics and semiotic theory and methodology have provided the means to go beyond the earlier approach of identifying and quantifying the number and duration of different types of teachers and pupil behaviour Good and Brophy, 1973; Cinclair and Coulthard, 1975.

Ý It's important to make such a comparison because returning to the hypothesis is crucial to basic scientific thinking. Describe how the data were summarized and analyzed.
However, the experimental methodology should also include controlling factors. This section contains graphs, data tables or any notes made during the experiment. In conventional statistical evaluations, provision of details is not required. For example, what happens when the protist encounters an obstacle? Of the three, Euglena was the only one that had chloroplasts, an organelle common in plants. Ý It is perhaps the most important part of the report because it is where you demonstrate that you understand the experiment beyond the level of simply doing it. We nearly always avoid use of first person in this section of a paper. The name of your professor.

Bess Ruff is a PhD student of Geography in Florida. Table 1: Tests and Results for Gram Negative Bacteria Test Purpose Reagents or Media Observations Results Gram Stain To determine whether the bacteria was gram negative or gram positive Crystal violet, Iodine, Alcohol, Safranin Red Rods Gram Negative bacteria Casein To determine if the enzyme casease was produced to break down the milk enzyme casein Milk Agar white opaque Milk Agar changed color where bacteria was smeared, turning a brown color Positive, the bacteria produced casease The first test performed on the gram positive bacteria was the Nitrate Test which turned red after adding reagents giving a positive result meaning the bacteria reduced nitrate into nitrite or something further. Style: Write the text of the Results section concisely and objectively. As a starting point, two lessons were selected for analysis ….
