When writing an abstract for a research article, several tenses can be used.
Do not begin each section on a new page. If one section ends part of the way down the page, the next section heading follows immediately on the same page. One important general rule to keep in mind is that a scientific paper is a report about something that has been done in the past.
The present tense is, are is used when stating generalizations or conclusions. The present tense is most often used in the Introduction, Discussion and Conclusion sections of papers. The paper should read as a narrative in which the author describes what was done and what results were obtained from that work.
By reading the title, the work being reported should be clear to the reader without having to read the paper itself. The title, "A Biology Lab Report", tells the reader nothing.
An example of a good, self-explanatory title would be: This title reports exactly what the researcher has done by stating three things: The environmental factors that were manipulated light, temperature.
The parameter that was measured growth. The specific organism that was studied the bacterium, Escherichia coli. If the title had been only "Effects of Light and Temperature on Escherichia coli ", the reader would have to guess which parameters were measured.
That is, were the effects on reproduction, survival, dry weight or something else? If the title had been "Effect of Environmental Factors on Growth of Escherichia coli ", the reader would not know which environmental factors were manipulated.
If the title had been "Effects of Light and Temperature on the Growth of an Organism", then the reader would not know which organism was studied. In any of the above cases, the reader would be forced to read more of the paper to understand what the researcher had done. If several factors were manipulated, all of them do not have to be listed.
Instead, "Effects of Several Environmental Factors on Growth of Populations ofEscherichia coli " if more than two or three factors were manipulated would be appropriate. The same applies if more than two or three organisms were studied.
The researcher would then include the names of the bacteria in the Materials and Methods section of the paper. An abstract is more than a summary.
A summary is a brief restatement of preceding text that is intended to orient a reader who has studied the preceding text. An abstract is intended to be self-explanatory without reference to the paper, but is not a substitute for the paper.
The abstract should present, in about words, the purpose of the paper, general materials and methods including, if any, the scientific and common names of organismssummarized results, and the major conclusions.
Do not include any information that is not contained in the body of the paper. Exclude detailed descriptions of organisms, materials and methods.Using tenses in scientific writing Tense considerations for science writing (past, present or future).
The other relates to whether an paper or report to another, and they can also vary between one scientific discipline and another.
The lone exception seems to be APA style, which "dictates that writers use the past or present past tense when citing previous research," i.e. "Smith () noted" or "Smith () has noted." If you're governed by APA style, follow their guidelines and use past or present past tense.
