A Note on Writing: One of the most common complaints about the writing of lab reports, and especially the grading of lab reports, concerns the importance of writing.
Record the barometric pressure. The key to all of modern science is reproducibility for a result to be accepted as the correct result, other experimenters need to be able to reproduce the result.
The pressure in the room was It is a description of what you did, and is not to be written in the style of instructions to someone else.
If there are results that would be best presented in a figure, label the figure clearly, and be sure to refer to it in the text. General Writing Taking the most controversial element first, at least one-third of the grade for each lab report will be based on the general quality of the writing.
You can be a brilliant scientist, able to produce great results in the lab, but if you are unable to communicate those results effectively to another person, all your lab skills are worthless. Repeat with a 10 g sample of your unknown. A lab report, like a scientific paper or an engineering proposal, should have a clear and logical flow of ideas: Before you hand a lab report in, read it over, or have your lab partner read it over.
A lab report, like a scientific paper, is first and foremost about communication, conveying your results to the reader, and as such proper writing is essential.
Be sure to include uncertainties in any measured quantities. Discuss the sources of error, both random and systematic, and how the errors affect your results.
When writing the report, pretend that you have chosen to do the experiment of your own free will, motivated by scientific curiosity, rather than having the experiment forced upon you by the inhuman taskmasters of the Physics Department.
Experemint 10 As described in the lab manual: An even more basic element of good writing is proofreading. I especially liked the part where the blabber gas exploded when heated scaring my partner I think that may be why she broke the thermometer. Heat over a flame until half of the ice has melted.
Correcting for our water results this made our measurements — This section serves primarily to help the reader understand the significance of the experiment and all the issues that are later addressed. On a finer level, each sentence and each paragraph should have a clear point, and serve to advance the argument being presented.
There is no better way to make yourself look foolish than to turn in a written document with a huge, glaring spelling error in the first paragraph especially in the current age of automatic spelling checkers in word-processing programs.
Including a sketch of the apparatus is not sufficient description; you must also describe the apparatus briefly in words. Bring the liquid to a boil over a flame.
Present your data and calculations. The key to good writing is organization. Be concise--for example, often just giving the name of the method is sufficient.
Repeat with a Writing is more than simply stringing together a disjointed collection of unrelated thoughts.Lab Activity: Measuring with Metric 6 Volume Exercise 1: Practicing measurement accuracy. At your lab table you should have a glass bottle, a small plastic cup, and a test killarney10mile.com and record their volumes in the table below.
Hint: note that you have a faucet and sink to help with this task. Table Container Measured volume. Here are two examples of a lab report. The first is what not to do, the second is a cleaned-up and much improved version of the same report.
This was followed by a similar measurement of our solid unknown. The Barometric pressure in the lab was measured to be mmHg. Table One – Experimental Data. Trial. Water. Melting. Physical Measurement Laboratory We determine the definitive methods for nearly every kind of measurement employed in commerce and research, provide NIST-traceable calibrations, and disseminate standards and best practices throughout the nation.
