Lab Report Why writing lab reports is challenging Writing lab reports is very common among college students.
We will be using a format for the lab reports which is similar but modified to formats for scientific papers. That is, you must include an abstract, introduction, materials and methods section, results section, discussion, and literature citations.
Your grade on the reports will depend on completeness, scientific accuracy and insight, organization, and writing skills. We will discuss this more in lab. We expect lab reports to be prepared using modern word-processing programs. For partial or point reports they will be adjusted as needed.
It should state the purpose of the experiment, mention the techniques used, report results obtained, and give conclusions.
The point of the abstract is to give a concise summary of the whole report. The most common mistake that students make is not including summary data. Chromosomal DNA was successfully isolated from Bacillus subtilis strain using a modification of the Marmur technique.
Spectrophotometric analysis revealed some contamination with protein, but little RNA contamination.
The pure DNA had a concentration of 1. The DNA was sterile, as judged by streaking onto penassay agar. In most cases, you should include background information on the organisms used and explain the theory behind the techniques.
Much of the introductory material should be referenced and references have been put on reserve for you at Steenbock Library. You are encouraged to also search the library for other relevant references.
Instead of asking you to tediously rewrite all your lab notes into a materials and methods format, we instead want you to include your lab notes in lieu of materials and methods. The lab notes should be complete, including all raw data, observations, calculations and appropriate graphs.
We do not expect nor do we want rewritten notes. A short paragraph should be sufficient, along with any relevant charts and graphs labeled well. Remember to title and provide legends for all graphs and tables.
The graphs and tables should be comprehenable independently of their association with the text. This does not mean you simply report the results again, but rather interpret and discuss their significance. Results should also be compared with those in the literature, if possible. Be sure to give proper citations.
If problems were encountered during the course of the experiment, how might they be rectified in the future? Are there any other things we could do to make this a better experiment or to more specifically address the initial question posed?
Are there any better techniques available that would allow one to more accurately generate data? Is there more than one way to explain the results?
Your results may support your initial hypothesis, but there may be more than one conclusion that could be drawn from your results. Lastly, do not spend enormous amounts of time explaining data that cannot be explained!
Reference Citations As required in all scientific literature, statements of fact, not considered "common" knowledge, must be properly referenced. Relevant articles for each of our experiments are on reserve in Steenbock Library. Give complete citations of all literature cited in the report.
Here are some examples: A procedure for the isolation of deoxyribonucleic acid from microorganisms. Disruption of bacterial cells. Academic Press, London and New York.The lab report or the scientific paper is the vehicle of persuasion; when it is published, it is available to other scientists for review.
If the results stand up to criticism, they become part of the accepted body of scientific knowledge unless later disproved. Chemistry Lab Resources (for CHM 1XX and 2XX Labs): Parts of a lab report Here you can find tips about organizing your lab notebook, how to effectively create graphs and table for lab reports, places to locate protocols and property information, and how to properly cite resources.
Writing lab reports is very common among college students. After carrying out experiments or when working on a project, you will be required to present your findings via a paper.
The project may be exciting and full of wonderful experiences, however putting your discovery into writing . Biology Lab Report Customized For Any Need of Students If you've chosen biology for your research work or for higher studies, you are likely to do experiments on different aspects of biology.
You may be expert at doing those experiments at a laboratory. But, writing a report on those lab experiments needs some special skills. When you have started writing a biology lab report, you may find a.

HOW TO WRITE AN UNKNOWN LAB REPORT IN MICROBIOLOGY GENERAL Unknown reports in microbiology are written in scientific format. Scientific writing is written differently from other types of writing.
The results of the exercise or experiment are what are being showcased, not the writing. The purpose of scientific writing is not to entertain, but to.
