General Chemistry 123 Lab Grading       Middlesex County College                   Dr. Lansinger

 

Laboratory Grade:

 

Average of All Lab Reports             50%

2 Lab Exams                                     50%

 

The overall objectives of the laboratory experiments:

  • To reinforce chemical principles and calculations learned in lecture
  • To teach students proper laboratory techniques and collection of data

 

Before your scheduled Lab:

 

READ the LAB ahead of time.  If you cannot tell me what lab you are scheduled to perform, you will not be allowed to do the lab that day.

 

In the Laboratory

Read the notes that will be on the blackboard, and get the professor’s initials or signature on your data sheet before you leave the laboratory for the day.

 

Collecting Data and Writing Reports:

 

Please use pencil for lab reports.  The report must be neat, legible, and dark enough so that I can read it.

 

Reports are due one week after completion of the lab and must be handed to me BEFORE entereing the lab (at the beginning of the lab period in which they are due).

 

One week or less late is minus 10 points, more than one week late is minus 20-30 points

 

Reports are graded on the basis of % 100

 

Use of Significant Figures: correct significant figures must be used when applicable (measured numbers such as mass measurements from a balance, volume measurements from graduated cylinders, volumetric flask measurements, pyncnometers and burettes, cm measurements from rulers).  From 5-30 % of the total lab report points may be deducted for incorrect usage.

 

Units must be added to numbers when appropriate.

 

Neatness of Lab Report:  if I  cannot read the lab report, I cannot grade it. 

 

Failure to attend a lab will result in a zero for that Lab.  If you miss a lab, you might be able to attend some other instructor’s lab period but you must ask for permission to attend a lab other than your regularly scheduled lab.  See Lab Coordinator, MH room 203 for schedule.

 

Cheating:

 

Cheating in the laboratory consists of copying another individual’s answer to any lab question.  You may cooperate with your lab partner in discussing possible explanations.  However, you must put the answer in your own words. 

 

Cheating also consists of copying any other person’s work during a quiz or exam, using crib sheets or using information that is stored in cell phones or calculators.
