Chemical and Biomolecular Engineering Department Laboratory I CBE Spring 2015

GENERAL INFORMATION  Safety  Safety precautions are to be observed at all times. At the minimum, this means that safety glasses must be worn by everyone in the laboratory at all times. Care must be used in the handling of chemicals to avoid spills and to avoid contact with the skin.

Laboratory Format and Procedures  Organization of Student Groups and Laboratory Projects  Students are to be organize into groups of three persons. Each group is to perform four projects during the semester.  A group leader, who is in charge of directing the work for the lab, should be selected by, and from among, the members of the group. (This responsibility should rotate among the members.)

Laboratory Projects Each project consists of:  One lecture (Friday Lectures)  Three laboratory sessions and  Three reports --a preliminary report; progress report; and a final report.

Friday lectures  On Fridays preceding each of the 4 lab rotations, a minutes lecture will be given by each instructor to all of her or his groups for that particular rotation. The concepts and the objective of the experiment will be explained. All students should take notes, as no other such information session will be given.

Friday lectures for spring 2015

Laboratory Session 1  The session starts with a meeting with the instructor in charge, either in his or her office or in the lab, for an oral defense of the precise contents.  A brief typewritten paragraph describing the experimental plan and procedure should be submitted to the TA who is in charge at that time.

 Accordingly, a discussion between the TA and the students concerning the work, will take place to insure that students have an accurate plan of action.  It is suggested that a rough draft of the Introduction, theory, and experimental sections of the final project report is begun at this time. Continue

Laboratory Session 2  The Progress Report.  A one-page progress report of results obtained in the first session, and plans for the second session are due at this time. Graphs and tables and calculations of results obtained should be appended.  The progress report should be submitted to the TA in charge of the experiment. A summary discussion of the report with the instructor will be conducted in the laboratory.

Laboratory Session 3  No specific format or report requirements are specified for this session.  During this session each group should perform examination of the experimental apparatus for the next assigned project

Final Project Report and Oral Defense.  The final project report is due at the beginning of the next scheduled laboratory period following Session.  There are no exceptions to this deadline  The reports are to be submitted to your professor before 2.00PM (before starting the new experiment).  Each group should schedule a meeting with the instructor for an oral defense/discussion of the written report  Each member of the group should be prepared to defend and/or discuss any part of the final report.

Oral Presentations  For the last project of the semester, each group will make a formal 15-minutes oral presentation on that project  A 10-minute question-and-answer session will be followed.  All groups should submit an Extended Abstract at least 24hr before their oral presentation instead of the last final report.  All students are required to be present for all presentations by the groups in their section.  The location and other specifics will be announced later in the semester.

Laboratory Notebook  In the notebook should be kept a neat, labeled and dated record of all work associated with the experiment, including a copy of the precise, all raw data, the settings on the experimental controls, any problems encountered in the experiment and what was done to fix them and why, all calculations, a copy of your progress report, etc.

Grading Group:Weeks 1-3, 4-6, 7-9, Names:

P.S.  If a group does not pass the first secession's examination a reduction of 10 points from their total grade will occur.  Failure to submit the progress report will result in a 10% reduction of the final report grade.  A penalty of 10% per day will be assessed on a project grade for the late submission of the final written report.  At the end of the semester the scores will be normalized before grades are assigned.
