Revision 105050012 of "Laboratory report" on enwiki

{{Uncategorized|February 2007}}

'''Laboratory reports''', commonly referred to as lab reports, are [[science|scientific]] papers that enable researchers to communicate their findings with others, e.g. findings such as results of scientific [[experiment]]s. Another important function of lab reports is the record-keeping of experiments. This allows other researchers to examine or to duplicate the experiment.

Researchers and scientists often use the lab report format to publish their accomplishments. However, they are not the only ones to write these documents; most reports are done by students of high schools and colleges for schoolwork, and when they are competing in [[science fair]]s.

The format and rules of lab reports are very complicated and must be strictly followed for easier communication. However, these rules may vary in different fields or even to different people. For example, in a school, each teacher may have different preferences of format and style for lab reports from their students.

==Format==
Using the format as a guideline when composing a report will help one avoid leaving out important aspects of an experiment, making the report logical and easier to understand. Although there is not a standard format or style for such a document, most lab reports contain basic elements as listed below.

====Title page====
Title page is the cover for the document. On the title page, there should be some general information that helps others to identify the experiment. For example, if this lab report is a group assignment in a high school, then the title page should provide: the name of the experiment, full name of the student and his/her lab partners, and the date on which the experiment was conducted.

====Abstract====
Abstract is a miniature of the report of about 100–200 words. It summarises the whole report. Therefore, it is the part to be written last. A smaller and more informal lab report may not require an abstract.

====Introduction====

;Purpose
Explains what the experiment is trying to find out, as well as the experiment's significance. Sometimes there is also a brief mention of the method used in the experiment.

;Theory
Explains the theory or principles on which the experiment is based and past findings by other researchers and scientists. Any symbols or variables used in the report must be defined here. A diagram may be needed.

Which Fruit Fly Traits are 
Dominant, Recessive, Autosomol or X-Linked 

I. Statement of the problem.
	In this experiment we were trying to see which fruit fly traits are dominant, recessive, autosmol or x-linked. The independent variable of this experiment was how many fruit flies with or without mutated genes were mated. The dependent variable of this experiment was the amount of fruit flies that inherit or didn’t inherit the mutated gene. I think if you mated wild type with a mutated fly and in the first generation all of the flies are wildtype, then the mutation is recessive. 
Then after if you mate two of the flies and the mutation is in the fly generation but only in males (with seventy five percent wildtype and twenty five percent mutated males) then the disorder is X-linked.
II. Procedure
	On day one of the experiment Josh and I started by choosing which traits each of us was going to observe in the mating. He chose to observe the inheritance of the following traits: wing size, wing vein, and wing angle. I chose to observe the inheritance of the following traits: eye color and body color. First I went to the website www.sciencecourseware.org/vcise/drosophila. First I went to the virtual computer and ordered one wild type (red eyes) female fruit fly and one mutated (purple eyes) male fruit fly. Next I unpacked the fruit flies and put them in the mating jar in the incubator for 2 weeks.

====Equipment, materials or apparatus====
Equipment, materials or apparatus itemises the setup of the experiment. A lab report in psychology, for example, will not involve the use of equipments, hence this section would not be present in a psychology lab report. However, in other fields of research such as physics, this section usually contains a diagram and explanations of how the equipments are assembled, as well as a list of materials used.

====Experimental procedure====
Experimental procedure is a narrative of how the experiment was conducted. It should be written in [[past tense]] and [[grammatical person|third person]]. The author should describe each step of the experiment in great details in this section. Another scientist should be able to read this and use it to conduct the experiment.

====Results====
The data obtained through the experiment is presented here in tables with descriptions. Graphs are used when they are appropriate. Also include any calculations.

====Discussion====
Here, the significance of the results is explained, and a conclusion is reached. The author will then list possible sources of systematic and random error, and will suggest ways to improve the design of the experiment.

====References====
This section provides an alphabetised list of books or other published resources cited in the report. For more information, see [[citation]] and [[plagiarism]].

====Appendices====
The appendices are sections of data, diagrams, and other related items that are not included in the above sections. Each appendix should be referred to at least once from other sections of the report. For example, at the beginning of the results section, one might add: "See Appendix A: Raw Data Chart".
