Kathryn Rowberg, PhD
Office: G-267
Phone: 989-2284 please leave a message with the secretary
email: rowberg@calumet.purdue.edu I check my email every weekday morning and
respond as quickly as possible.
Office Hours: As posted (Mon 4-5, Wed 4-5, and Tues 1-2) and by appointment.
Lecture: Mon and Wed 5-6:30 pm in Gyte-103
Required Laboratory: Room G-206
Prerequisites: Chemistry 115 or equivalent
Text: Martin Silberberg, General Chemistry, McGraw Hill, 2009; I also recommend
buying the Student Study Guide. Reading in the text ahead of class lecture is expected.
Final Exam: Monday Dec 14 6-8 pm.
OBJECTIVE: Chm 116 is a collaborative course (merit based and no competition for
grades) with a goal of success for all. The objective of this course is to teach the laws
and principles behind these topics and gain a conceptual understanding, to understand the
models used to predict chemical behavior, to make calculations using these concepts and
to learn the application of these topics in order to solve problems. The student should
gain a deeper understanding of chemistry concepts--solutions, solubility, acids and bases,
buffers, equilibrium, thermochemistry, kinetics, electrochemistry, and nuclear chemistry.
LECTURE ATTENDANCE: Attendance at all classes is expected. The best way to
participate in the lecture is to read the text before class, take notes on the material
covered and work on the problems presented in class. Bring a calculator to class so you
can practice computations. I will show computational techniques for most Texas
Instrument calculators. I highly recommend TI-89, but others will work. Each student is
responsible for all the material presented in the lecture and the lecture will augment the
material in the book, therefore your notes should be helpful when studying for an exam.
If you miss a class, please get additional class notes from a classmate and see me during
office hours to clarify any questions regarding the material. Keep in mind that chemistry
is a rigorous discipline that requires mastery of preceding material to fully understand
future material. You will profit greatly by keeping up-to-date with the problems assigned
and by reading ahead in the text.
CLASSROOM POLICY: Chm 116 is a collaborative course (merit based and no
competition for grades) with a goal of success for all. Students are expected to behave
professionally in the classroom. Cell phones and beepers must be turned off or to vibrate
during class. Texting during class disturbs those around you, so be courteous and text
after class. Arrival and departure to class should be timely, with minimal interruption in
extenuating circumstances where one must leave early (please sit by the door).
Blackboard: Chm 116 is available on the Purdue University Calumet ecourse Blackboard
site. To access the site, go to the Purdue University Calumet homepage and click on
ecourses. Enter into Chm 116 and choose from the available menu the information you
want. There will be copies of the syllabus, samples of exams from previous years,
handouts from class, copies of overheads used in class, announcements from class, etc.
Although email options are available, I can’t reply to email sent through Blackboard.
Please use your Purdue email and always include your section number. My email
address is at the top of the syllabus. I usually check my PUC email daily except during
weekends and breaks.
GRADING AND EXAMINATIONS: Scores from the top four of five quizzes (20 points
each), scores from 10 of 11 lab periods (20 points/week of lab time), homework
(complete the chapter questions for 10 pts credit), three exams (100 pts each), and the
final cumulative exam (150 pts) will be used to calculate your grade. Lecture quizzes
will be given at the beginning of class and usually announced one week in advance.
There are no makeup quizzes, but the lowest lecture quiz score will be dropped. The
lowest lab score (of the 20-point labs) will be dropped. This allows for an unforeseen
absence that will not count against you. Only students given permission in advance by
the instructor and those with excused absences will be permitted to take a make-up exam.
More than two unexcused absences from the lab is reason to initiate administrative
withdrawal of the student.
Homework is to be completed and submitted in class. Homework will have a due
date and there will be a 2-point penalty for each day late. All homework problems will
be collected but only three will be graded per chapter. The answers to homework
problems will be available after the homework has been graded.
Exams are graded carefully. If you wish to have your exam regraded, write the
problem number at the top front of the exam and the reason for regrading.
All students are held accountable to the Honor Pledge. Any academic dishonesty
will be dealt with according to University Policy (see handbook). Giving or receiving
unauthorized aid is strictly forbidden. When doubt exists concerning aid, ask if it is
permitted. For example, doing homework problems in a group is not only allowed, but
encouraged. Furthermore, notes are not allowed in quizzes, although you may ask the
instructor questions during the quiz. Any act of dishonesty during a quiz, exam, or in the
lab will be penalized at the discretion of the instructor.
Special lecture events and extra credit assignments will be mentioned in class.
Students will receive 5 extra credit points for each completed assignment for a maximum
of 10 points.
The exam dates have been set and are in this syllabus. Please note them and
transfer them to your calendar.
CHM 116 Tutoring: Individual and group help is available at the Center for Student
Achievement (Gyte-100). See their schedule for available tutors.
Supplemental Instruction: Supplementary Instruction is available and highly
recommended. Students find that these sessions give greater confidence over mastery of
the material.
EMERGENCY PROCEDURES: In case of emergency, please notify campus police as
soon as possible (989-2911). Be aware of emergency exits in the classrooms and
familiarize yourself with the evacuation plan posted in each room. Please discuss safety
concerns with the instructors. An Emergency Printout is available from the instructor.
SPECIAL ASSISTANCE: If you are a student with a documented disability who will
require academic/classroom accommodations in this course, please register with the
Coordinator of Services for Students with Disabilities in the Student Support Services
Office located in the Student Union and Library Building (SUL), Room 341, phone
numbers: 219-989-2455, 219-989-2454(voice/TTY) or 219-989-2920.
Contact with Professor: Please feel free to drop by my office and talk about the course,
chemistry questions, career ideas, summer jobs, etc. I would like to foster student
participation in science activities and I want to be a resource to you in achieving your
goals. Remember Chm 116 is a collaborative course (merit based and no competition for
grades) with a goal of success for all.
