Lecture:
Laboratory
Rules:
| 1. |
Students
must thoroughly read the assigned
work. It will be assumed that
they have studied the assigned
work and have understood the
majority of the material and
technical terms before the start
of the experiments. |
| 2. |
All the original data have to
be recorded in a Report sheet
during the laboratory sessions.
Data recording on rough sheets
of papers are not allowed. In
order to check for the originality
of the data, ball pen or inerasable
pen should be used. If correction
has to be made, just cross it
out. They must hand over the
Report sheet to the demonstrator
for their signature after data
count. |
| 3. |
For
safety reasons, students are
requested not to leave their
equipment unattended during
the lab. session. In the case
of special circumstances,
please seek the support of
the class teachers/demonstrators. |
| 4. |
All
practical contribute to the
final results of the sessional
course. Thus any absent laboratory
session automatically means
lost marks for the final grade.
Under special circumstances
(supported by documentary proof),
e.g. illness and other reasonable
causes a laboratory session
may be re-scheduled upon approval
of the head of the department. |
| 5. |
During
the class, students will be
continuously assessed by performance
test on each and every experiment. |
| 6. |
To
ensure your fellow students
can proceed with their experiments
in a degree of comfort and without
undue noise and other disturbances,
keep the noise level down and
stay in your own laboratory
bench area. Mobile phones should
be switched off during the experiments. |
How
to prepare laboratory Report
The
report sheet should contain the
following:
Front
Page:
•
Name of the Experiment
• Experiment No.
• Name of the Student
• Student ID No.
• Name of the Department
• Group
• Batch No.
• Date of Allotment
• Date of Performance
• Date of Submission
Inside
Page:
| • |
Theory |
| • |
Apparatus |
| • |
Experimental
data (During the Sessional Class) |
| • |
Calculations
Relevant
formulae should be stated, i.e.,
only those used to calculate
experimental results. Great
care should be exercised in
performing simple arithmetic
operations and the calculation
should be thoroughly checked. |
| • |
Result |
| • |
Discussion
Students
should write discussion on the
overall accuracy of your results
and on any systematic errors
in the experiment or agreement/discrepancy
with expected values. |
