2) Lecture: Experiment: credit = 0:3 h:1

-Lab: 402, 406 & 704(Goong-Ni Laboratory Building, E6-5)

2. Course Objective

1) To teach basic laboratory techniques

2) To introduce to elementary methods of assessingthe significance of experimental measurements

3) To provide experiences that enable the studentsto acquire positive attitude toward CHEMISTRY,or SCIENCE

1) Preparation in advance for experimental work.• Pre-laboratory reading preparation for successful

experimentation.• 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 timeswhile in the laboratory.

3. Course Requirement

3) Writing up and submission of lab reports.

Includes the following (but see evaluation):

Observations and experimental detail.

Detailed method of processing the experimentaldata. (For Quantitative analytical experiments)

Calculations and Conclusions regarding theaccuracy and the precision of experimental resultsand errors and the inherent errors based on themeasurements.

3. Laboratory Makeup Policy 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)

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

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.

Missed scheduled make-ups will be counted as zero and will not be rescheduled unless exceptional circumstances exist.

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

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

2) A Good Teaching Assistant………..a. Grades lab reports correctly and fairlyb. Gives feedback on the lab report that is helpful c. Isenthusiastic about teaching the lab

4. Due Date of Lab Report

The submission will close at 23:59 on the day before next lab class begins

5. Experimental Group

One or Two Student(s)Per One Experimental Group

There are four objectives for you, thestudent, in the laboratory:

Todeveloptheskillsnecessarytoobtainandevaluateareliableoriginal result. Torecordyourresultsforfutureuse. To be able to drawconclusions regarding your results (with the aid of some coaching and

readinginthebeginning). Tolearntocommunicateyourresultscriticallyandknowledgeably

By attentively reading over the experiments in advance, and by carefully following directions andworkingsafelyinthelaboratory, youwill beabletoaccomplishall theseobjectives.
