1.     Title page - be sure to include your name, date, section number, experiment title and number, and instructor name

2.     Objective

 
3.     Introduction –

 

a.     Include a statement of the purpose of the experiment and how this experiment will fulfill this purpose.  (Hint:  The purpose of this experiment is to determine the accuracy of a variety of measuring devices and to learn statistical methods of analyzing data.)   

b.     Include some background information.  This should include a definition such as systematic error, random error, accuracy, precision, mean, Deviation, absolute and relative error etcÉThis should also include any important equations such as mean and standard deviation. Remember to define variables in equation. Keep it short and precise, one paragraph.

 

4.     Procedure - reference all of the procedures that you used for the entire experiment. (Reference should include document name, author if known, page number(s))  If any changes have been made to the experiment by the instructor they should be explicitly described here.

 

5.     Results and calculations - It probably makes sense to copy the pages out of the excel worksheet for this section. 

 

6.     Discussion 

 

a.     For each piece of equipment, classify the precision and accuracy of the volume contained or delivered as good, fair, or poor.  Explain, briefly, why you made the choices you did.

b.     The water used in your calibration was quite pure. Suppose, however, that impure water containing some salt was inadvertently used instead of pure water and that the impure water had a density of 1.00117 g/mL at the temperature of your calibration. What do you expect to observe.

 

¯  Keep the discussion precise it should not take more than 2 paragraphs, make sure to support arguments with data.

 

NOTE: Discussion is not a place to tell me whether or not you had fun or if you liked the experiment.  I would love to hear you tell me what you do and do not like in person, but this is not part of a scientific document.

 

7.     Conclusion - tell the results, one or two sentences should be plenty and evaluate your objective.

8.     Attach summary page from excel and you lab book pages.

a.   The lab book pages should also be appended to the back of formal report.  These should be the original copies of your work.  If these are not legible, you need to make a Xerox copy of the data pages.  You need to keep the originals so that if the report is lost you will have your data.

NOTE:  Many of you did not have your lab notebooks at the time of doing this lab.  This means that you will be appending the sheet of paper that you and I signed as containing the original data.

b.   Make sure that your lab notebook includes the following

i)      Completely referenced procedure including any changes made by the instructor

ii)    Any safety precautions that may be necessary (Were there any here???)

iii)   Clearly laid out and completed data tables are nice.  Do not redo them just to make them pretty.  As long as you have organized the data in a way that you can figure out and explain to me it is OK.  Calculated values need not be included as they are on the computer spreadsheets

iv)   Each data sheet is signed and dated at the end of a dayÕs work by both the student and the instructor.
