1. Safety
Following safety rules is crucial and prevents all of you from the sad consequences of accidents. These consequences may  include loss of sight, severe skin burns, poisoning, even death.
It is obligatory to wear safety goggles or approved safety  glasses at all times when performing an experiment (imagine concentrated sulfuric acid which burns the organic tissue in a matter of seconds, splashing in your face and eyes). You must wear the goggles on your eyes, not wrapped around your head or neck.
Contact lenses are absolutely not allowed, even underneath the goggles.
YOU WILL NOT BE ALLOWED TO PERFORM THE EXPERIMENT IF YOU COME TO THE LAB IMPROPERLY DRESSED!
Proper clothing means:
 -  close-toed shoes, NOT sandals, Birkenstocks, etc.
 -  long pants , or at least knee-length skirts,
 -  long sleeve shirts , definitely no tank- or sleeveless  tops.
This is to protect you from spills that happen frequently.
Your clothing cannot be  loose or  unbuttoned. Loose fabric flying around your body can catch on fire or knock down the bottles with chemicals, thus causing harmful spills.
Your long  hair can easily catch on fire or be dipped in the toxic solution, so it has  to be tied back.
It is also prohibited to  bring any food or drinks to the lab. These items can be easily contaminated with chemical dust or vapors, and you may suffer severe poisoning after ingesting them.

Three (3) points will be  deducted from the score of the student who has to be reminded twice to abide by the rules.
The third-time  violator will receive a failing grade.

2. Necessary supplies
a.  Approved safety goggles or glasses with side-shields - mandatory ( do not leave in the drawer)
b.  A roll of paper towels - mandatory ( do not leave in a drawer with equipment, give to the  instructor).
c.  It is recommended, that students have the lab coats  or protective aprons.

3. Grading
a.  Data/calculation sheet, prelab and  postlab questions  are  worth 4 points each.
     Total: 12 points per lab.
b.  There are no points  for attendance with the exception of the first  lab.
     Three (3) points are awarded for being there (not a bonus).

Assignments
c. The answers to the prelab questions are due before the experiment begins.
d. The completed data sheet and answers to the postlab questions are due the week following the experiment.
e. The postlabs  and data sheets that are one (1) week late (turned in 2 weeks after the lab) will be worth only  70% of the awarded points ( 30% deduction will be taken).
   The postlabs  and data sheets  that are more that one week late will NOT be accepted.
NOTE: Lab experiment may be modified, some parts of the procedures may not be performed. In such cases the prelab and postlab questions in the lab modules will be modified to reflect the procedural changes.

Final Grade
100-93% =A;    93-89 % =A-; 88-85 % = B+; 84-80% =B;   79-74% =B-; 73-71% =C+; 70-67 % =C;  66-63% = C-;  62-59 % = D+;   58-53 %= D;     52-50% = D-;     ?50%= E

4.  Make-up labs
If you are unable to attend a regularly scheduled lab due to illness, unavoidable business trip or a major life trauma, you need to notify the instructor or lab coordinator in advance. You may  be able to make up the lab missed with another section the same week, subject to space availability. Your postlab, report and prelab is due  in that lab, with your lab section and the  instructor’s name written  next to yours. The make-up instructor will date and  initial your paperwork and submit it to the instructor of your section. Your data sheet must be also  initialed by the instructor of that section before you leave the lab.
Regular make up lab scheduled in the last week  is only  for  those who missed a lab.
No more than one lab can be made up during the make up lab. There is no make up for the first week lab.

5. Equipment check-in and check-out
Each pair of students is assigned two drawers: top- for the  glassware and the bottom one-  for the metal  equipment.
Each pair of students in every lab section will  check the equipment received at the beginning of the semester into the drawers and fill out the standard equipment sheet.  The information on the reverse side of the equipment sheet must include:  both names (PRINTED), the lab section  ( e.g. Chem 1130-002), the drawer # ( e.g. # 14) and the lock combination
(e.g. 12-24-36, 14-32-56).
One equipment sheet will be used for more than one section. Each pair of students will use the same equipment sheet at the end of the semester  to check out the equipment.

6. Taking care of equipment
The drawers and equipment are shared  between  lab sections. Therefore, it is crucial that  student s take good care of the  equipment , clean it  properly and have it restocked when broken.

 Please follow the following rules:
-  do not store personal items (lab coats, goggles, etc. ) in the drawers,
-  after the experiment is finished, clean the glassware thoroughly with brush, soap and water then rinse, before  you replace  it in the drawer. Always invert wet test tubes in a rack to drain-dry.
-  keep  the glass equipment in a separate drawer from the metal equipment (with the exception of a  spatula and  the test tube brush),
-  replace every broken item  immediately.  You will not loose points for breaking glassware provided that you ask for         replacement.
- return to the cart all of the additional items that are provided by the instructor to perform certain experiment (thermometers,  styrofoam cups, crucibles, additional test tubes,  etc). Do not place this equipment  in the drawer. There is a limited supply of such equipment, and other groups will also use it.  All of the additional glassware items  (crucibles,  flasks, beakers, etc) need to be cleaned before  they are returned .
Digital thermometers must be rinsed, dried, and TURNED OFF.
-  report to the lab instructor any problems (broken, missing and dirty glassware,  metal  clamps thrown together with  glass,  drawers not locked, etc.) at the beginning of the lab  session; give  the drawer and the lab session  number.

Two (2) points will be deducted from the score of the pair of students that used  the drawer  last.
Keep in  mind that if you do not report the problem, the next  person will, and you will be held  responsible.

Please bear  in mind that  the rules and regulations are set up to provide fairness and equal treatment for every student, as well as to protect the students’ health and life.
Have  a safe,  enjoyable and interesting time in the lab.
