4) Laboratory Manual

       Laboratory Manual for Principles of General Chemistry, 10th Edition, J.A.Beran, John Wiley & Sons, Inc.

 

5) Objectives for the Course

 1_ To teach basic laboratory techniques

 2_To introduce to elementary methods of assessing the significance of experimental measurements

 3_ To provide an experience that enables the students to acquire positive attitude toward chemistry, or science.


6) Course Requirement

    1_Preparation in advance for experimental work

       (a) Pre-laboratory reading preparation for successful experiment

       (b) "Pre-lab"quizzes are or pre-lab reports are required relating to the experimental details.

    2_ Wearing of eye protection and lab clothing at all times while in the laboratory.

    3_ Writing up and submission of lab reports. Includes the following (but see evaluation)

        (a) Observations and experimental detail

        (b) Detailed method of processing the experimental data

            ( for Quantitative analytical experiment)

        (c) Calculations and Conclusions regarding the accuracy and the precision of experimental  

             results and errors and the inherent errors based on the measurements


7) Grading

 : Total 10 experiments X 100 pts = 1000 pts

  A(45-50%), B (45%-50%), C-D (5%) per one class

 

  Evaluation Method and point distribution per experiment

   : One experiment = 100 pts

 

         1) Pre- and post- laboratory quizzes  (30 points)

 

         2) Attitude (20 points)

            (a) Lateness (5 pts)

            (b) Lab Safety or Cleanup (10 pts)

            (c) Concentration or Comprehension (5 pts)   

          

          3) Laboratory Reports  (40 points)

            (a) Introduction

            (b) Result

            (c) Discussion

               o Summary

               o Assessing the results

               0 Conclusions

          (d) Reference

 

         4) Laboratory Questions (10 pts)

Attitude

(20 points)

Attendance: late coming -2 ~ -5

When you arrive at the lab before TA calls your name, you get a full score, 5 pts.

If you arrive 10 min late after the beginning of the lab, you get 3 pts. When you arrive between 10 min and 20 min, you will get the score, 0 pts. For being 20 minutes late, you can't participate in the lab experiment. (No chance any more.)
Attendance: absence without notice 0

If you are absent 3 times without any notices, F credit will be recorded.

*The lab experiment is ONLY permitted in registered class.

*Only valid excuses are illness (with a valid doctor's excuse) or unusual circumstance beyond your control (death in family), etc.

* The student must submit written verification of them for an excused absence.

Lab safety & Cleanup

-5, -10

Personal Protective Equipement:  Safety glasses, Attire (lab coat)

Wear approved eye protection at all times while in the laboratory. The penalty is -5 pts for this.

 

Care of balance: Anyone found to be leaving spilled chemicals in the balance area or bench will lose 5 pts  for each violation. Any chemicals spilled on the benchtop or the balance pan during transfer are to be cleaned up immediately by the student.

 

Cleanup of Lab Bench:The students are responsible for cleaning up their immediate lab bench area before leaving lab. This means wiping up any spills and disposing of any paper towels from the benchtop and sink. Failure to do this result in a deduction of -5 pts.

 

Sink Disposal of chemicals: DO NOT discard any chemicals down the laboratory sink. The penalty is -5 pts for this.

Concentration & Comprehension

-5

Check list (-5 pts)

- playing with gossiping

- cell phone (touching, ringing, chatting), and so on

- Repeated failure of the same experiment

* Student must submit Result Summary to TA before leaving  lab.

*Lab partner will share data, however separate lab report must be written by each student.

*Duplicate reports will be given a zero.

*Allowing someone to submit or resubmit your work as theirs will result in a zero for both parties.

Laboratory Questions

(10 points)

   

You should solve the questions and submit them in lab class to your TA.

*Identical question answers will receive a zero.

 

8) LAB POLICY

 

Policy regarding late lab reports

Lab reports are due at the start of the scheduled experiment, unless otherwise instructed.

Your score on that report will be reduced by a percentage, based on when your TA received your report.

0  Within 24 hours: 10%.

0  Between 24 and 48 hours: 20%.

0  Between 48 and 72 hours: 30%.

0  More than 72 hours: 100%.

 

Laboratory Makeup policy

0 Make-ups are only for those who missed labs for a legitimate reason and got TA's permission to make up lab.

  (Give a written documentation to your lab TA during the next lab or bring it to his lab and ask permission to make

  up the missed lab.

0  Missed labs without a valid excuse, shall count as zero (0) and the student will not be allowed to make up

  this missed lab.

0 Students are not allowed to make up late lab reports or to make up more than two experiments

  during the scheduled lab make-up time. Re-doing labs is not possible.

0 Missed scheduled make-ups will be counted as zero and will not be rescheduled unless exceptional

  circumstances exist.

0  If more than three labs are missed with or without valid excuses student shall fail the course.

0 Your lab TA will let you know the make-up schedule and the due dates for make-up reports.
