Example of a lab report abstract
As one takes higher level classes the teacher will specify if he or she wants an abstract to be included in the written reports. If it is required, it is the first part of your report, directly following the title page and proceeding the introduction.The abstract, although it comes first logistically, always should be written last. It needs to be written last because it is the essence of your report, drawing information from all of the other sections of the report.
It explains why the experiment was performed and what conclusions were drawn from the results obtained. Laboratory reports are written for several reasons. One reason is to communicate the laboratory work to management. In such situations, management often bases company decisions on the results of the report. Another reason to write laboratory reports is to archive the work so that the work will not have to be done in the future. This web page presents a commonly used organization for laboratory reports.
Abstract,Introduction,Procedures,Results and Discussion,Conclusions, andAppendices.You should not assume, though, that this organization will serve all your laboratory reports. Rather, you should pay attention to the organization requested by your instructor who has chosen an organization that best serves your experiments. AbstractThe abstract presents a synopsis of the experiment. The following guidelines for preparing an abABSTRACTIn this experiment, chromatography was used to analyse amino acidsin solution.
Standards were used to identify unknown amino acidsin a mixture. Ascending layer chromatographywith an isopropanol-based solvent was used to separate the aminoacids, which were then detected with ninhydrin. Theunknown mixture analysed was found to contain aspartate and histidine.It was observed that hydrophobic amino acids were most mobile. This technique was shown to be aneffective way of analysing unknown mixtures of amino acids.
IN ACONCISE, CONVERSATIONAL,3rd person manner. A person reading it.your teacher, ascience fair judge, or your classmates should be able to easily understand whatwas going on as well as the outcome in the lab. This is a summary of the basiccontent of the experiment. It should state the purpose of the experiment,mention the techniques used, report results obtained, and give conclusions.
Thepoint of the abstract is to give a concise summary of the whole report. The mostcommon mistake that students make is not including summary data. Example:Chromosomal DNA wassuccessfully isolated from Bacillus subtilis strain 151 using a modification ofthe Marmur technique. Spectrophotometric analysis revealed some cSAMPLE DESCRIPTIVE LAB REPORTExamination of Protozoan Cultures to Determine Cellular Structure andMotion PatternAbstractProtozoans are unicellular eukaryotes with either plant-or animal-like characteristics.
Through careful observation, we analyzedvarious protozoan cultures in order to identify characteristics associatedwith cell structure and movement of these one-celled organisms. We foundthat Protists exhibit certain characteristics that allow them to becategorized into different groups, mainly determined by their locomotionpatterns. Despite differences in locomotion and the varying plant-likeand animal-like organelles, all protists share key characteristics andfunctions that allow them to feed, grow, and reproduce--processes essentialfor survival and common to complex organisms.
An abstract is a short summary of a longer report composed after the lab report is written. Abstracts are meant for others to read. It gives an overview of what happened in the lab and tries to persuade the reader to read the full-text version of the lab report. Some online databases only list abstracts. As technology advances, the ability to write an informative abstract is more important.
Decide on an appropriate style of abstract for your lab report. There are two different types of abstracts: informative and descriptive. A descriptive abstract identifies the scope of the paper. It is rarely used and is only for long reports. An info.
