for an
A.P. Lab Report
TITLE - This is a general statement about what is being done in the laboratory.
PURPOSE - This is a specific statement or question being looked at in the experiment.
PROCEDURE - This is an abstract only. It should be only 3-7 sentence reference to
the method used in the lab and stated in the laboratory handout.
THE ABOVE THREE SHOULD BE DONE ALONG WITH A DATA TABLE BEFORE YOU
COME TO DO THE LAB. IF I CHECK AND IT IS NOT DONE YOU WILL NOT DO THE LAB--
SORRY.
OBSERVATIONS - This should include all observations. Every lab should have this section.
MEASUREMENTS [DATA TABLE] - This includes any and all measurements made
during the lab. The measurements should be made using as much precision as
the instruments offer. These measurements should include all and be well organized. Keep results separate from measurements.
RESULTS - Carefully labeled sample calculations should be included for each significant type of calculation.
Then display all of the calculation results in tabular form. If the experiment
has only a few numerical results, make sure they are clearly labeled and set
apart from the measurements so that they are easy to find. Use and scientific notation.
ERRORS - List source of errors, as many as you can. Do not tell me you massed it
wrong unless you did. No human error! Tell me how the errors would or did
affect your results. Give me the % error if you know the true value. If not,
get the % precision which can be a real pain. I will go through an example
with you on this. Take notes about it when I do.
CONCLUSIONS - This is an interpretation of the results and a summary. What did you discover? This
is not a place to restate the results. If you did come up with a number like
"the density was 4.56 g/ml," you should put it in here.
CHARTS and GRAPHS - The data and results should be recorded properly in
the appropriate type of chart or graph. Make graphs the [click here->]right way.
CHEMICAL EQUATIONS - If there were any chemical reactions that were
done during the experiment you should have a balanced equation.
LATE REPORT - There will be 25% taken off the total grade per day if the report is passed
in late. Most lab reports are due the day after the lab is completed Check
with me on this one.
ORIGINAL DATA - The original data, just as it has been recorded, “should” be included
with the lab report. BUT I DO NOT WANT THIS. When you go out and work for the industry they would
have you keep this each day, and initial it.
