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 4050 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.
Continue

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.
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.

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.
