3.0 GENERAL INSTRUCTIONS FOR LABORATORY PRACTICALS:

Posted by admin on July 24, 2017 | No comments

GENERAL INSTRUCTIONS:

1. You must arrive on time since instructions are given and announcements are made at
the start of class.
2. Awork station and lab partners will be assigned to you in the first lab meeting. You
will do experiments in a group but you are expected to bear your share of responsibility
in doing the experiments. You must actively participate in obtaining the data and
not merely watch your partners do it for you.
3. The assigned work station must be kept neat and clean at all times. Coats/jackets
must be hung at the appropriate place, and all personal possessions other than those
needed for the lab should be kept in the table drawers or under the table.
4. The data must be recorded neatly with a sharp pencil and presented in a logical way.
You may want to record the data values, with units, in columns and identify the
quantity that is being measured at the top of each column.
5. If a mistake is made in recording a datum item, cancel the wrong value by drawing a
fine line through it and record the correct value legibly.
6. Get your data sheet, with your name, ID number and date printed on the right corner,
signed by the instructor before you leave the laboratory. This will be the only valid
proof that you actually did the experiment.
7. Each student, even though working in a group, will have his or her own data sheet
and submit his or her own written report, typed, for grading to the instructor by the
next scheduled lab session. No late reports will be accepted.
8. Actual data must be used in preparing the report. Use of fabricated, altered, and
other students’ data in your report will be considered as cheating. No credit will be
given for that particular lab and the matter will be reported to the Dean of Students.
9. Be honest and report your results truthfully. If there is an unreasonable discrepancy
from the expected results, give the best possible explanation.
10. If you must be absent, let your instructor know as soon as possible. A missed lab can
be made up only if a written valid excuse is brought to the attention of your instructor
within a week of the missed lab.
11. You should bring your calculator, a straight-edge scale and other accessories to class.
It might be advantageous to do some quick calculations on your data to make sure

that there are no gross errors.
