How to write a good abstract biology

This article has been cited by other articles in PMC. Abstract Abstracts of scientific papers are sometimes poorly written, often lack important information, and occasionally convey a biased picture. This paper provides detailed suggestions, with examples, for writing the background, methods, results, and conclusions sections of a good abstract.

Testing pH with Plant Pigments Abstract The purpose of this investigation was to determine which types of plants and their parts could be used as pH indicators. The pH standards were produced by a serial dilution using two starting pH solutions of 1 and 14 and distilled water.

The azalea petals were soaked in isopropyl alcohol to extract any visible pigment. Using a spot plate, each pH standard was placed in a numbered spot and two drops of the azalea petal extract was added. The resulting colors were recorded ranging from light pink in a pH 1 spot to a deep blue in a pH 14 spot.

To determine the validity of the pH test, each of the pH standard spots were tested with pH paper. Since the colors changed, when the flower petal pigments were subjected to each of the different pH standard solutions, the hypothesis was supported by the data.

Testing pH with Plant Pigments Abstract This experiment uses plant pigments and tests them to see if they are good pH indicators. The hypothesis was that if a carrots pigment were removed and tested with a range of pH solutions, then it would prove to be a good pH indicator.

Isopropyl alcohol was used to extract pigment from two grams of ground up carrot.

The pigment was yellow. Then, using 14 numbered test tubes; 9ml of distilled water was put in all test tubes except one and Then a serial dilution was performed going from one to six and then 14 to 8.

This provided pH solutions ranging from a pH of one to a pH of Then a spot plate was numbered and a few drops from each numbered test tube were put in the corresponding spot on the spot plate. Next, a few drops of the carrot pigment were placed in each spot of the spot plate. The color change was then observed.

This experiment supported the null hypothesis because the experiment showed that a carrot is not a good pH indicator. All of the solutions in each spot plate remained yellow.

Does the title describe clearly and precisely what you investigated? Is the question clearly stated in a manner that your abstract will support?

Does the abstract explain why we did this experiment?

Does the abstract state the problem. Did you clearly describe what you intended to investigate? Does it summarize the methods? Did you state what factors were varied and how they were varied?

Did you summarize what measurements you took and how you took them? Did you describe the controls? Is all of this information given in a logical order and succinct manner? Is it it interesting and clear? Is the purpose of the lab clearly stated?

Is a statement of how the problem arose included? Is the hypothesis written in an investigative format cause and effect? Is it written in an If, independent variable then, dependent variable form?

Did you write a null hypothesis? The null hypothesis is often the reverse of what the experimenter actually believes; it is put forward to allow the data to contradict it. Depending on the data, the null hypothesis either will or will not be rejected as a viable possibility.

Did you include amounts of materials, chemicals etc.?writing biology laboratory reports This is a general guide for writing most basic biology laboratory reports.

The format may vary depending on the class and the teacher so it is important to check with the professor when there are any questions. HOW TO WRITE AN ABSTRACT: Tips and Samples Leah Carroll, Ph.D., Director, Office of Undergraduate Research An abstract is a short summary of your completed research.

Here’s the abstract for a paper (that I haven’t written) on how to write an abstract: How to Write an Abstract. The first sentence of an abstract should clearly introduce the topic of the paper so that readers can relate it to other work they are familiar with. Department of Wildlife Biology, University of Colorado - Boulder.

Use the active voice when possible, but much of it may require passive constructions. Write your Abstract using concise, but complete, sentences, and get to the point quickly. Use past tense A good way to get on track is to sketch out the Introduction.

Fly lab report p. 5 Fly lab report p. off properly before the test. Flies taste food with specific cells on their tarsal hairs. Each hair has, in addition to a mechanoreceptor, five distinct cells – alcohol, oil, water, salt, and sugar – that determine its acceptance or rejection of the food (Dethier, ).
