1.
Objectives:
Chemistry 15 is an introductory chemistry course primarily intended to prepare
students for the college level chemistry 1A/1B sequence. This course also meets
the general education requirements for laboratory science.
The course covers the chemical principles concerning the composition of matter
and its reactions. Chem.15 requires no previous chemistry background, although
introductory algebra (Math 11A or 11R) is required. This course will emphasize
the understanding of chemical concepts more than the quantitative aspects of
chemical problem solving.
2.
Required Materials:
a. Text: Introduction to Chemistry, Bauer, et al.,McGraw-Hill, 3e., 2013.
b. Chemistry 15 Lab Manual (available at SJCC Bookstore) and handouts (by
Song).
c. Homework packet (by Prof. Song).
d. Safety goggles to protect your eyes (available at the bookstore).
e. Electronic calculator with scientific functions (log, exp, etc.).
Recommended or Optional Materials:
a. Laboratory apron or coat (highly recommended).
3.
Basis of Evaluation:
a.
Midterm Exams:
Three (3) midterm exams will be given during the lecture, of which two
(2) highest scoring exams will be used for computing grade. Exams will
cover all work up to the time of exam including the homework
assignments. For the exam schedule, consult the lecture schedule
attached. No make-up exams shall be given.
b.
Quiz:
For the quiz schedule, consult the lab schedule attached. No make up quiz
will be given unless you consult with the instructor ahead of the scheduled
quiz.
c.
Final Exam:
2
A comprehensive final exam will be given. Students who miss the final
exam without notifying the instructor will not receive grade higher than C
for the course.
d.
Homework:
Homework problems will be periodically collected and graded.
Homework should appear neat and legible. It should be done on separate
sheets (no torn out spiral notebook, please), stapled properly before
turning in. No late homework is graded.
4. Grading:
The course grade earned will depend on the sum total of points earned in lecture
and lab. The following weighting factors will be used.
Hourly exams
Final Exam

The final course grade is based on the sum of individual student achievement in
relation to minimum performance standard. The following table gives the
approximate grade assignment for the accumulated point total (lecture and lab).
Accumulated point total (%)
90 - 100%
80 - 89

Attendance counts toward your grade. Coming to class late often or attending part of the
lecture or lab will be counted as absence. Any student who miss the equivalent of one
week’s lecture and lab without notifying the instructor will be dropped from the class
roster. Notify the instructor if you have personal and compelling reasons to avoid being
dropped from class.
This instructor deems academic honesty very highly. Copying another person’s work
verbatim for lab reports, cooperating in quizzes and exams are examples of dishonest
behavior and will result in disqualification from the course. Please conduct yourselves in
a manner that would dispel any suspicion in the instructor’s mind all together. Regarding
school policies on the academic honesty and other student conducts including sexual
harassment can be found in Chapter 5, p40 of the College Catalogue available at

Best wishes for a successful Spring semester in Chemistry 15!

Laboratory:
Your performance in lab will be based on the lab reports, and lab conduct. Your lab
portion of the grade will be divided between lab reports/lab conduct and dry lab
exercises. Lab Instructor will provide dry lab exercises to be done during the lab that will
be collected periodically.
Partial attendance or frequent tardy attendance of the lab will be counted as absence as
judged by your instructor.
Your lab report will be evaluated based on the completion of the assigned task, accuracy
of calculations, accuracy and precision of your results. To get perfect score in the lab
report, you will have to meet all of the above criteria. Your conduct in lab as judged by
your lab instructor, such as being on time, working safely in lab and doing assigned work
honestly and conscientiously, will be used as a part of the lab evaluation as well.
There will be penalty assessed for late reports. 10% of the maximum point will be
deducted for each lab period that it is overdue. To avoid penalty, turn in your lab report
in time by all means.
Your instructor deems academic honesty essential not only for your lab conduct, but also
for making of a responsible decent citizen. Student suspected of copying other’s lab
report verbatim will have his work voided and will face the dismissal from the class.
Please behave in a mature responsible manner to avoid suspicion by your instructor.
I wish you a safe and rewarding lab experience during the Spring semester.
