AP CHEMISTRY
2015/2016
TEACHER: Ms Sarah Cabrera
AP Chemistry – Course Syllabus
Class Profile
AP Chemistry is a year-long, 120 minute course.
A typical week is organized to provide:
2-3 days of lecture focused on the key objectives
listed in the syllabus, including teacher
demonstrations.
1 day review/assessment of topics/skills
25% of time involves lab activity. Labs may exceed
one 120 minute class, depending on the
requirements of the specific lab activity. In addition,
some sections/objectives are more conducive to lab
activity than others and will have more lab activity.
Big Idea 1
The chemical elements are fundamental building materials of matter, and
all matter can be understood in terms of arrangements of atoms. These
atoms retain their identity in chemical reactions.
Big Idea 2
Chemical and physical properties of materials can be explained by the
structure and the arrangement of atoms, ions, or molecules and the forces
between them.
Big Idea 3
Changes in matter involve the rearrangement and/or reorganization of atoms
and/or the transfer of electrons.
Big Idea 4
Rates of chemical reactions are determined by details of the molecular
collisions.
Big Idea 5
The laws of thermodynamics describe the essential role of energy and explain
and predict the direction of changes in matter.
Big Idea 6
Any bond or intermolecular attraction that can be formed can be broken.
These two processes are in a dynamic competition, sensitive to initial conditions
and external perturbations.
Science Practice 1
The student can use representations and models to communicate
scientific phenomena and solve scientific problems.
Science Practice 2
The student can use mathematics appropriately.
Science Practice 3
The student can engage in scientific questioning to extend thinking or to
guide investigations within the context of the AP course.
Science Practice 4
The student can plan and implement data collection strategies in
relation to a particular scientific question.
Science Practice 5
The student can perform data analysis and evaluation of evidence.
Science Practice 6
The student can work with scientific explanations and theories.
Science Practice 7
The student is able to connect and relate knowledge across various
scales, concepts, and representations in and across domains.
AP Chemistry Objectives:
The AP Chemistry course is designed to be
the equivalent of year-long college general
chemistry (worth 2 courses – 8 credits!!!).
Therefore, this course enables freshmen
students to undertake second-year work in
chemistry or enroll in classes that require
general chemistry as a pre-requisite.
For other students, the AP Chemistry course
fulfills the laboratory science requirement
and frees time for other courses.
AP Chemistry Objectives:
AP Chemistry should meet the objectives of a
good general chemistry course. Students in
such a course should attain a depth of
understanding of fundamentals and a
reasonable competence in dealing with
chemical problems.
The course should contribute to the
development of the student’s abilities to think
clearly and to express their ideas, orally and
in writing, with clarity and logic.
Chemistry 1 vs. AP Chemistry
1. Qualitative Differences: largely
with respect to the kind of laboratory
work done by students and depth of
material.
2. Quantitative differences:
the number of topics treated
the time spent on the course by
students (1 to 2 hours at home)
the nature and the variety of
experiments done in the laboratory.
Prerequisites:
The AP Chemistry course is designed to be
taken only after the successful completion of a
first course in high school chemistry (Chemistry
1).
A student ideally should score an A in Chemistry
Honors to ensure adequate background
knowledge.
In addition, the recommended mathematics
prerequisites for an AP Chemistry class is the
successful completion of a second-year algebra
course and pre-calculus course.

c)
Calculating/interpreting results based on the quantitative data
obtained.
Labs:
Unless otherwise noted, each laboratory will be
“hands-on” and will involve:
physical manipulation of equipment and
materials in order to make relevant observations
and collect data
use the collected data to form conclusions and
verify hypotheses
communicate and compare their results and
procedures (informally to classmates and in a
formal, written report to the teacher)
Labs
Students are expected to abide by all
laboratory safety regulations. Safety glasses,
gloves, and aprons will be required for most lab
experiments (provided by the school).
For every day that an assigned lab report is
late, the student will lose 10 percent. If a
student is missing more than one lab each
quarter, they will receive an “incomplete” until
this deficiency is rectified. Once graded labs are
returned, late labs will have a 50 percent
reduction in points.
Labs
Prepare carefully for each laboratory period.
First, read about the entire experiment
Secondly, review unfamiliar concepts in your
(any) chemistry text.
Finally, prepare a brief lab write-up in your
notebook on the experiment (see below).
Except for taped in graph paper or data tables,
everything in the laboratory notebook should
be handwritten in ink (not red ink). The lab
write-up should include in order:
Lab Write-up in Notebook
I. Title of the experiment. Note: The title
should be descriptive. “pH Titration Lab” is
descriptive, “Experiment 5” is not descriptive.
Please include an actual name for the
experiment and underline with straight-edge.
II. Date. This is the date the student
performed the experiment.
Lab Write-up in Notebook
III. Purpose/Objectives of the
experiment. Two to four statements of
what is to be accomplished in the
experiment is required. Essentially, what
is the “point” of the experiment. It is true
that one of the purposes of the lab is to
learn, but it is inappropriate to include that
as a written objective in the lab notebook.
Lab Write-up in Notebook
IV. Procedure. A brief outline of the
experimental procedure which should be
complete enough that you could do the entire
experiment without the given lab instructions,
even if the lab were to be done a year later. To
accomplish this, first read the instructions over
a few times to get an idea what is to be done
in the lab. Then, write the procedure in your
own words with enough detail for you to
accomplish the task. Correct your write-up if
there are errors.
Lab Write-up in Notebook
V. Prelab questions and answers. Write the
question or a brief sense of the question. Then
answer the question using the appropriate
source. Don't copy each other's work! The
question should be answered in complete
sentences and all work to derive a numerical
answer should be shown.
Lab Write-up in Notebook
You will need to either re-write the question
or incorporate the question in the answer.
The idea here is that when someone (like a
college professor) looks at a student’s lab
notebook, they should be able to tell what the
question was by merely looking at their
report. Be aware of significant figures and
units in your answer. You may be graded on
how clearly you show your work.
Lab Write-up in Notebook
VI. Data Tables. As with the previous four
items, the necessary data tables for recording
measurements and observations should be set
up in the notebook before lab. The data tables
should be comprehensive enough that you can
write everything into those tables without
scratch paper. Please record all
measurements and observations directly into
your tables during the experiment. It is very
important to record the units of measurement.
Lab Write-up in Notebook
VII.
Calculations/Graphs. The
calculations can be determined after the
laboratory time period. However, enough
calculations must be done before leaving
the lab to complete the report. All numbers
which are used in the report which were
not read directly from a measuring tool
MUST BE SUPPORTED BY VISIBLE
CALCULATIONS IN THE REPORT.
Lab Write-up in Notebook
Calculations should be clearly labeled
with units and also easily matched to the
numbers from the data tables. If you
cannot follow the logic of your derivation,
neither can the instructor!
Graphs need to be titled, axes need to be
labeled, and units need to be shown on
the axis. To receive credit for any graphs,
they must be at least ½ page in size.
Lab Write-up in Notebook
VIII.
Summary/Post-Law Error
Analysis Questions.
Answer the post-lab questions which are
given in the lab instructions. Write in
complete sentences and be sure to
support or explain all answers. Once
again, the questions must be incorporated
into your answers or re-written as with the
pre-lab questions.
Lab Write-up in Notebook
Show calculations if applicable to
question. Reiterate numbers from
experiment. For example, do not simply
indicate that “the temperature increased.”
State that the “temperature increased
from 22.0 degrees Celsius to 24.3 degrees
Celsius.”
Lab Write-up in Notebook
Conclusions. The conclusion is a discussion
of the results in the lab, whether the results
were as you expected or not. If your results
seem to be entirely misleading, there should
be some type of reasonable explanation
offered for the data you obtained. The
conclusion should include any difficulties that
you encountered, a discussion of possible
experimental error, and a conclusion on
whether or not you were successful in meeting
the objectives within the confines of
reasonable error.
Review the objectives you wrote in Section
II, and respond to them in the conclusion.
While it does make for interesting reading
on the part of the grader, please do not
include a discussion about the lack of
intelligence of your lab partner, or the "fun"
you had while doing the lab.
