Mandatory- AP Chem. prep-book: (old additions are fine) they allow you to see the information you
will be taught from a different perspective. If you cannot afford one, I have lots of extras you can
borrow for the year.
At the end of your second year of Chemistry you will be able to understand and interpret a broad
array of chemical behaviors and concepts. AP Chemistry has a “snowball” effect that builds off
previous knowledge. In order to survive, the Chemistry must be “learned”!

TEXT MESSAGE; remind 101 will be set up for all students to receive
reminder texts, and possible last minute class changes or adjustments
Grade Breakdown (per quarter): Calculating your grade is on a “total point” system. It is
as straightforward as it sounds. The number of points you earned throughout the quarter,
divided by the total number of possible points available that quarter.
Here are the approximate point values:
Quizzes/Homework: 10-20points(each)
Labs/Projects: 40-60points(each)
Test: 60-80points(each)
**NEW **
I will be using a series of abbreviations through-out this syllabus to align it with the collegeboard’s standards as the curriculum and test format for AP Chemistry continues to grow
and change. These will align with the AP Chemistry Course Guide below
http://media.collegeboard.com/digitalServices/pdf/ap/2013advances/AAPChemistryCED_Effective_Fall_2013.pdf
We will review these objectives as a class in great detail. The syllabus will provide an
outline for how we plan to meet and exceed the rigorous curriculum placed before us by the
college board, and we will welcome the challenge!!
We will be structuring your Chemistry knowledge around 6 “Big Ideas” (CR2)
Big Idea 1: Structure of matter
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: Properties of matter-characteristics, states, and forces of attraction
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: Chemical reactions
Changes in matter involve the rearrangement and/or
reorganization of atoms and/or the transfer of electrons.
Big Idea 4: Rates of chemical reactions
Rates of chemical reactions are determined by details
of the molecular collisions.
Big Idea 5: Thermodynamics
The laws of thermodynamics describe the essential
role of energy and explain and predict the direction of changes in
matter.
Big Idea 6: Equilibrium
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.
Abbreviations needed for syllabus interpretation:
BI=Big Idea
EU=Enduring Understanding
EK=Essential Knowledge
LO=Learning Objectives
CR=Curricular Requirements:
SP=Scientific Practices
New AP Chemistry Exam Format:
The exam is 3 hours long and includes both a 90-minute multiple-choice section and a
90-minute free-response section. The multiple-choice section accounts for half of your
grade, and the free-response section accounts for the other half.
Section I consists of 60 multiple-choice questions, either as discrete questions or question
sets, that represent the knowledge and science practices outlined in the AP Chemistry
curriculum framework, which students should understand and be able to apply. Question
sets are a new type of question: They provide a stimulus or a set of data and a series of
related questions.
Section II contains two types of free-response questions (4 short and 3 long), and each
student will have a total of 90 minutes to complete all of the questions. Section II of the
exam will contain questions pertaining to experimental design, analysis of authentic lab
data and observations to identify patterns or explain phenomena, creating or analyzing
atomic and molecular views to explain observations, articulating and then translating
between representations, and following a logical/analytical pathway to solve a problem.
Students will be allowed to use a scientific calculator on the entire free-response section
of the exam. Additionally, students will be supplied with a periodic table of the elements
and a formula and constants chart to use on both the multiple-choice and free-response
sections of the exam.
Curricular Requirements:
CR1 Students and teachers use a recently published (within the last 10 years) college-level chemistry
textbook.
CR2 The course is structured around the enduring understandings within the big ideas as described in the
AP Chemistry Curriculum Framework.
CR3a The course provides students with opportunities outside the laboratory environment to meet the
learning objectives within Big Idea 1: Structure of matter.
CR3b The course provides students with opportunities outside the laboratory environment to meet the
learning objectives within Big Idea 2: Properties of matter-characteristics, states, and forces of attraction.
CR3c The course provides students with opportunities outside the laboratory environment to meet the
learning objectives within Big Idea 3: Chemical reactions.
CR3d The course provides students with opportunities outside the laboratory environment to meet the
learning objectives within Big Idea 4: Rates of chemical reactions.
CR3e The course provides students with opportunities outside the laboratory environment to meet the
learning objectives within Big Idea 5: Thermodynamics.
CR3f The course provides students with opportunities outside the laboratory environment to meet the
learning objectives within Big Idea 6: Equilibrium.
CR4 The course provides students with the opportunity to connect their knowledge of chemistry and
science to major societal or technological components (e.g., concerns, technological advances, innovations)
to help them become scientifically literate citizens.
CR5a Students are provided the opportunity to engage in investigative laboratory work integrated
throughout the course for a minimum of 25 percent of instructional time.
CR5b Students are provided the opportunity to engage in a minimum of 16 hands-on laboratory
experiments integrated throughout the course while using basic laboratory equipment to support the
learning objectives listed within the AP Chemistry Curriculum Framework.
CR6 The laboratory investigations used throughout the course allow students to apply the seven science
practices defined in the AP Chemistry Curriculum Framework. At minimum, six of the required 16 labs are
conducted in a guided-inquiry format.
CR7 The course provides opportunities for students to develop, record, and maintain evidence of their
verbal, written, and graphic communication skills through laboratory reports, summaries of literature or
scientific investigations, and oral, written, and graphic presentations.
LABORATORY REQUIREMENTS &
PROCEDURES
Lab Safety
Each student must complete a lab safety course with a passing quiz score
of 85%, and have a SIGNED lab contract. A parent/guardian signature
is required as well.
General Lab Procedure(CR5a)
Lab information and procedures will be provided for the students prior to
the lab date.
Pre Lab : The day before the lab students will complete a pre-lab
assignment for each lab, generally a small quiz and lab preparation
procedures. The quiz and pre-lab assignments generally take half a
period.
Lab: The day of the lab, you must efficiently perform the procedure and
follow ALL lab safety requirements. Generally labs can be completed in
our fifty five minute time-frame. Any additional time needed to complete
the lab will result in staying after school that day. The key to getting
through each lab is to understand what the procedure is BEFORE you
walk through the door, have it re-written in your own words to help
expedite the lab. Students will work in groups of two or three depending
on the equipment restrictions. Work as a “team” or the labs will be
difficult to complete in the allotted time.
Post-Lab: Assignments and discussion questions will be given in class
the day following the lab, and generally take half a period to complete.
This is a “general” procedure, and will be tailored to fit the needs of each
lab individually.
Occasionally we will have 2-day labs, which are indicated on the lab list, located
on the last page of the packet.
Lab Notebooks and Binders (CR7)
Each student must keep an ORGANIZED bound lab notebook. (ie: composition
notebooks work great) You will create a table of contents and record all titles, re-written
procedures, observations, and data in this notebook. The lab folder is used to hold the “original”
lab packets, instructions and procedures, along with the pre and post lab assignments. This will
keep everything in one convenient place.
Heed the following when collecting data in your lab notebook:
-Take data and observations only on the front of each page.
-Take all data in ink.
-Be relatively neat. If an error is made draw a single line through it. If a substantial
portion is to be discarded, cross it out with an X.
******* -All entries should be labeled with appropriate units!!!!!
-Date each page.
Lab Reports (CR7)
It is extremely important to prepare and submit a well written report. The reporting of
results and findings is one of the most important phases of carrying out an experiment. Your
report must include (IN ORDER):
Title: Include the date,period, and the names of your lab partners.
Purpose/Abstract: 1 or 2 sentences describing the major goals of the
experiment.
Procedure: Since in most cases the procedure is already described, you need
only cite the reference to the lab packet unless otherwise stated.
Data: This section needs to contain all charts and pertinent data used in
calculations. The information needs to be organized, and headings should be
self-standing. (needing no explanation)
Calculations: Show all equations and work used to derive any answers
requiring you to perform mathematics. If any equations are repetitive, you only
need to show your work for ONE of the equations.
Conclusion: Discuss the results of your experiment. Was the purpose
achieved? If not, what were the errors? This is a summary of your knowledge of
the experiment you performed. The conclusion makes clear that you understood
the goals and skills the lab was enforcing. You will answer any discussion
questions or exercises in this section as well.
Discussion Questions: These are often asked in the lab packet itself, WHICH
YOU MUST RETAIN!! These are worth a lot of points and are typically were
some students struggle to come up with logical and reasonable answers.

Final Extension Activity (CR4): As a review we will take the flame test lab that you
performed at the end of the first quarter, and review ionic flame color to refresh your
memory. We will then let you select other groups of your choice to work with to predict
and test solubility of the two aqueous ionic solutions. Finally you will balance and write
the chemical reaction to predict the amount of ppt in grams that should be produced if
any. It is a GREAT way to review a ton of concepts and learning objectives in a 1 hour
activity.
