COURSE DESCRIPTION
Chemistry 102 is the second half of a yearlong overview of the field of chemistry. We will cover the
properties of solids, liquids, and gases, the rates at which reactions occur, and the driving forces that
cause reactions to occur. We will also discuss acid base reactions and electrochemistry. This course will
expose you to new concepts and techniques, challenge you to explain physical phenomena in
conceptual terms and challenge you to answer quantitative questions. Chemistry 102 is rewarding, but
expect to work hard. Set aside at least 10 hours per week outside of class for studying and practice.
Work a wide variety of practice problems and think deeply about the material every single day.
THE CHEMISTRY 102 COMMUNITY
Our class emphasizes teamwork and good sportsmanship. Grading is on a flat scale, not a curve. In
Chemistry 102, therefore, ultra-competitive behavior is not only unattractive, it is also unnecessary.
ACADEMIC HONESTY
Cheating is NOT a part of the Chemistry 102 culture, nor does it benefit the cheater. Academic
dishonesty carries heavy consequences: http://instrument.unc.edu/instrument.text.html#IPreamble.
Some student work (e.g. exams, Sapling) must be completed individually and without external aids.
Other work (e.g. group questions in class) may be completed with help from peers and/or selected
external aids. If you are unsure whether a task is intended to be individual or group work or whether
you may use outside aids, ASK!
All course materials including notes and assignments are covered by University Copyright Policy:
http://www.unc.edu/campus/policies/copyright%20policy%2000008319.pdf
CHEMISTRY 102 IS AN ENGAGED-LEARNING CLASS
How well you learn depends largely on your choices: do you engage with the material every day, or do
you cram for exams? Do you think deeply about what you’re learning, or do you skim the surface? The
course structure of Chem 102 is designed to reward activities that support learning with class points.
These are called Daily Work Points, and they comprise 15% of your grade.
To earn Daily Work Points, you will prepare for before each class period by completing a with a Warmup assignment: video lectures and/or selected textbook reading to do, followed by a graded Sapling
questions. We will then check your understanding in class and delve into more challenging topics with
clicker quizzes and group work. Chemistry 102 mentors and I will rove during these activities help you
build the skills you need in the right way. After class, you will reinforce your skills by doing textbook
practice problems and a graded online self-assessment (in Sapling). Each part of this class structure
has been shown to improve success in chemistry.
You may not earn a score higher than 100% on Daily Work, but many more Daily Work points will be
offered than are necessary to earn a 100% (see Daily Work grading chart). This will allow you to make
up points lost by the occasional missed class, dead clicker battery, or missed Sapling deadline.
WARM-UP ASSIGNMENTS
Video lectures and/or reading will be assigned for you to read/view before each class meeting. WarmUp assignments related to these assignments will be given in Sapling (Course = krumper). A Sapling
Warm-up will be due at 8:00 am every class day (MWF).
No late work will be accepted in Sapling for any reason. The Sapling clock will be used to determine
the submission date/time. This clock may differ from yours, so submit your work well in advance. You
may use your book or other resources, but all Sapling assignments are to be worked by you alone. No
collaboration is allowed before the due date, but discussion of Sapling content is encouraged after
you’ve turned it in.
CLICKER ACTIVITIES AND CLASS ATTENDANCE
We will do a variety of problem solving activities in class using clickers. Some activities will test your
mastery of the Warm-Up Assignment. For these clicker quizzes, you will be instructed to work
individually, and your score will be based on your performance. You may use notes you have taken on
the Warm-up on the clicker quiz, but other materials (e.g. your book) are excluded.
Throughout class period, we will learn new concepts and skills in lecture, then we will apply these to
more involved problems. You will work together with a team to master these tasks.
No makeups will be given for in-class clicker points. Your overall Daily Work score (15% of your grade)
is roughly 50% based on in-class work. Excellent attendance is required.
PRACTICE PROBLEMS
A list of recommended practice problems from your text for each exam’s content will be posted under
on sakai. These practice problems are the key to your success in chemistry. Years of experience have
shown me that successful students in the course do all of the recommended textbook problems and
they open their textbooks to solve problems every day.
SELF ASSESSMENTS IN SAPLING: COURSE = KRUMPER
Self-Assessments will be assigned in Sapling on a weekly basis. Self-Assessment problems are much
like end-of-chapter problems from the textbook, and they are intended to augment, rather than
replace textbook practice. Consider your performance on Self-Assessment as a measure of whether
you have done enough practice problems. Weekly Self-Assessments in Sapling will be due at 8:00 am
on Mondays.
EXAMS
See schedule for dates of midterms and the final. If you miss an exam unexpectedly (for any reason),
you will be graded under Option B, below. If you know will need to miss an exam in well advance (e.g.
for a medical procedure or University field trip), you may arrange to take the exam early.
Arrangements for early exams must be made at least two weeks in advance.
GRADING
Grade thresholds may be scaled down at the instructor’s discretion, but guaranteed minimum
values are listed below. (e.g. a score of 69% is guaranteed a C-)

Print up the list of recommended textbook practice problems and mark your progress on it. Keep a
spiral notebook or binder for your practice problems; it is useful for the purpose of review to have
them all collected in one location.
Do some chemistry every day. Complete all the Warm-Up Assignments before coming to class.
Complete all the recommended practice problems AS WE COVER THE CHAPTERS (not in the last week
before the exam).
Use the textbook wisely. While each student learns differently, be wary of over-reliance on the
textbook. We will emphasize problem-solving skills and reasoning over memorization and/or
description. As such, it can be a poor use of time to read the textbook carefully. Your time may be
best spent skimming the text to get an idea of the concept, working problems to deepen your
understanding, and reviewing the posted lecture notes to refresh concepts. Again, use the text
largely as a reference (like google) rather than reading it like a novel.
Be a good class citizen. Smile at your classmates and introduce yourself to them. Ask someone how
their day is going. Switch off all electronic devices (phones, computers, etc.) while in class.
Hand write your notes (on a printout of the provided ppt slides) and keep them organized.
Chemistry requires a lot of sketching and equation writing, so typing is not practical. Keep your notes
organized in a binder. Do your practice problems on PAPER (rather than on a white board!) and keep
these solved problems with your class notes.
Review to the class notes posted on sakai after class. The class is fast-paced and clicker activities are
presented rapid fire. Your time is best spent working out solutions to questions rather than
transcribing question text. It is wise to take sketchy/partial notes on in-class questions: just enough to
flag the question in your notes and work out an answer. All notes and clicker activities presented in
class are posted on sakai shortly after class. Look these up and fill in the gaps in the notes you took on
in-class questions.
Attend Q+A sessions. There are many Q&A sessions offered each week, hosted by mentors, Prof.
Bliem, and by Dr.K. Attend these sessions. Bring your questions and/or just bring your desire to learn.
Form a study group. Working with a study group outside of class will help you learn the material
deeply. Your in-class working group is a great place to form these connections. Exchange contact
information and follow up – call others and ask if they want to study together.
