Writing a Laboratory Report

The main purpose of the methods described in the experimental section of a laboratory report, project report, thesis or paper is to communicate sufficient information to allow an experienced chemist to repeat, your experiments. One of the goals.Of writing laboratory reports is to provide you with practice in writing in the generally accepted, style required for more professional publications. The following fwiints should be noted ... 

People who study science rely on computers, like the one in Figure 16, to record and store data and to analyze results from investigations. Whether you work in a laboratory or just need to write a lab report with tables, good computer skills are a necessity. 

Operates specific logical argumentation patterns in scientific arguing and writing, e.g. in a laboratory-report. 

Tsaparlis and Gorezi (2005,2007) have proposed the addition of a project-based component to a conventional expository physical chemistry laboratory. Project-type tasks were used, mainly taken from articles in the Journal of Chemical Education. Dming the performance of the project experiments, students were dedicated, patient and enthusiastic. The writing of the report and the oral presentation of the project were very demanding tasks. The evaluation of the work by the students through... 

Genetic tests are performed on a sample of blood, hair, skin, amniotic fluid (the fluid that surrounds a fetus during pregnancy), or other tissue. For example, a procedure called a buccal smear uses a small brush or cotton swab to collect a sample of cells from the inside surface of the cheek. The sample is sent to a laboratory where technicians look for specific changes in chromosomes, DNA, or proteins, depending on the suspected disorder. The laboratory reports the test results in writing to a person s doctor or genetic counselor. 

Write up a full laboratory report of your procedure and results. Include ... 

Since the collection contains over 100 documents faculty must choose which documents to use in their courses. The most effective mechanism is for faculty to require use of an SME from the very start of a course and build opportunities for students to learn the software as they complete homework and write laboratory reports throughout the semester. Thus one would start with a training exercise for the SME and follow with simple calculations and exercises in every homework assignment. As the semester proceeds one can introduce skills for... 

I also thank my wife, Christel, who patiently tolerated the lifestyle changes associated with writing a book. In addition, she designed experimental procedures and searched for ideal laboratory conditions for several experiments. I am happy to report that Mausi, our blue-point Himalayan, is still napping under the desk lamp. 

Use the following questions to write a complete laboratory report. Include all the equations and calculations that you used. 

In the development of a standard, a laboratory group may perform the research on which the document is based, write a report, and present it to a committee with a draft standard. Or, if most of the information is available, a task group may write the standard. In any case, a committee reviews and provides input to the document, so the committee provides a much broader information base. All laboratories benefit from the combined expertise. Thus, organizations that participate in standards development are pooling their resources for the common good. 

If a laboratory chemist is versed in the use of a technical library, he is more valuable to his employer than without such knowledge. His value increases in proportion to his know-how of where to look for information, and how to look for it. He should be familiar with the use of standard texts, technical encyclopedias, and above all. Chemical Abstracts. Many inquiries received by a consultant may involve only writing a letter for information, looking up material in report or information" files, or asking someone in the organization who might know the answer offhand. A number of examples illustrate the kinds of questions that have actually been received, and how the inquiries were followed up. 

Low stakes, quick writes are used for additional practice in writing the various components of a formal report. Students might be asked to take their laboratory notes from an experiment and re-write them as an Experimental section for a formal report or to write a Conclusion for a previously completed laboratory. This work is assessed in peer review groups and fellow students provide each other with constructive feedback. Higher stakes writing exercises are also assigned, to be handed in at the next tutorial and subsequently graded by the TA or instructor.
