Make sure that you read each experiment to be performed BEFORE coming to the laboratory. This will greatly improve your efficiency, understanding, and success of the experiment. It is advisable to bring a small container of dish soap and a roll of paper towels to be kept in your locker as the laboratory cannot supply these items.

All experimental reports are due at the beginning of the period one week after the final day of that experiment's completion in the laboratory. Lab reports may be turned in late up to one period with a 50% reduction in points. After one late period, no lab reports will be accepted. ALSO, NO MAKE-UP EXPERIMENTS WILL BE ALLOWED. There is plenty of time to complete each experiment within the allowed time. If three physical absences occur you will be dropped/failed.

In addition to your data sheets, a short purpose (in your own words) and discussion/conclusion section will be offered. The discussion/conclusion section should be based upon the data and observations obtained in the experiment. Allow these data and observations to lead you to a logical conclusion. Also, discuss possible sources of error that may be inherent in the experimental procedure. Always write in the third person, singular, impersonal form. Avoid lengthy discussions when a brief, to-the-point approach will work. Always be cognizant of your grammar!

Of the 3 exams that you will take, your lowest score will be dropped. If you miss an exam, the zero recorded for that exam will be the score that is dropped. Therefore, no make-up exams will be given. Your grade will then be based upon the following breakdown:

Exams:         50%
Experiments: 30%
Subjective*:  20%
                    100%

Once your % grade has been determined, any glass or equipment breakage will then be subtracted from this total based on the formula of 0.1%/$1.00.

Scores will be subjected to a standard curve and grades will then be determined.

*Subjective is based upon your performance in the following categories:

Attendance             
Originality
Independence     
Technique             
Laboratory attitude

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                

ACKNOWLEDGEMENT OF RESPONSIBILITY

 

I, have read and understood the operating instructions put forth by the computer tutorial in the library regarding the Mettler AE200 electronic balance. My signature affirms the fact that the above statement is true. I realize that by signing this statement while NOT having reviewed the computer tutorial, I will be liable for any and all damages that occur to the balance due to my negligence arising from failing to take advantage of this tutorial program provided.
