Welcome to AP Chemistry! This course is a mixed inquiry / lecture based course, where students will both be directing their learning with teacher facilitation mixed with the traditional lecture style course. Inquiry-based programs are designed to target and improve students’ scientific process skills: predicting, inferring, separating and controlling variables, comparing and contrasting, problem solving, using numbers and collecting, recording, organizing and interpreting data. Chemistry provides the students with the study of composition, properties, and changes associated with matter. The content of this course includes, but is not limited to, classification and structure of matter, atomic theory, periodic table, chemical bonding, chemical formulas, chemical reactions, balanced equations, behavior of gases, acids, bases, salts, and energy associated with physical and chemical change. Although all of these topics will be covered, this AP course will focus on five big idea topics: Equilibrium (including acids and bases), Kinetics, Thermochemistry, Electrochemistry (including Redox), and Intermolecular Forces.

AP courses are designed to “give all willing and academically prepared students the opportunity to participate in rigorous academic curriculum.”

Prerequisites for AP Chemistry: Successful completion of Chemistry I Honors with a B or better and Algebra II Honors. Advanced Placement (AP) Chemistry is a course designed to be the equivalent of general chemistry that is usually taken during the first year of college. The course is suitable for students who display a high level of competency in honors chemistry and a strong desire to pursue a major in the sciences as a college student. More information about the AP program can be found at ap. All students who enroll in this course are required to take the AP exam in May.

Required Supplies: It is impossible to participate in classroom activities, laboratory exercises, and discussions without the necessary supplies

-1 Flash Drive (can be small 8 gb)

-1 Spiral Notebook (This is for class assigned bookwork and notes.)

-1 Scientific Calculator (This is a must for all students in class. Graphing Calculators are acceptable as well. Preferred model for those that do not already have one is TI-30X IIS.)

-1 Dry Erase Marker (We are going to be doing a lot of activities using the white boards.)

-1 Binder with Notebook Paper & dividers for Chemistry (To store the handouts from class.)

Textbooks: Primary- Chemistry 8th Edition, Zumdahl, Zumdahl. 2008.

Secondary- Chemistry the Central Science, Brown, Lemay, Burnsten. 2006.

Class Review Book- Fast Track to a 5, Preparation for the AP Chemistry Exam. Zumdahll. 2009.

The primary text and class review books will be issued during the first week of class. The secondary text will be available to check out. It is the student’s responsibility to have their texts and keep them in good order. Replacement of the Zumdahl text is $125 and the Brown text is $50.

Grading Policy: Grades for this class will be weighted by the following percentages:

55% Tests / Quizzes

25% Laboratory Assignments and Weekly Lab Write Ups

20% Classwork / Homework / Class participation

Classroom Expectations: The school-wide rules are:

1.) Be on time. 2.) Remain seated until dismissed by the teacher. 3.) Come to class prepared.

4.) Make good choices. 5.) Show respect for the teacher, classmates, yourself, and the classroom.

Other classroom specific rules are:

-Complete all assignments on time and read your textbook as instructed & participate in class activities.

-Be in your seat on time and ready to work when the last bell rings. Repeat tardiness (3+) will result in a referral and a detention with me after school.

-Excessive talking or repeated disruption will result in loss of participation grade.

-Academic dishonesty will NOT be tolerated. This includes cheating on tests, copying assignments, and not putting equal effort into group assignments. Any academic dishonesty can result in the reception of a zero for the assignment.

-Cell phones are almost never permitted in class. Calculators are provided, and cell phones are a distraction that hinders the learning process. Students will be warned to put their phones away once. Subsequent times the following protocol will occur: the second time, the student will be conferenced with, the third time, parent contact will occur, and finally a referral will be written. Points will also be deducted from a student’s grade (under the employability points) if a cell phone is out during an unpermitted time.

-No fooling around, this is a laboratory.

-Food and drinks (with the exception of capped water) are not permitted in the lab.

-Chewing gum is a privilege and can be revoked at anytime if proper respect of the classroom is not observed. (i.e. I do not want to find it under the desks and if you are speaking to the class, please do not have it in your mouth.)

-If you “Christmas Tree” a test--- The Curve No Longer Applies to You!

The Exam

The exam is 3 hours and 15 minutes long and includes both a 90 minute multiple-choice section and a 105 minute free-response section. The multiple-choice section accounts for half of your exam grade, and the free-response section accounts for the other half.

Section I: Multiple Choice — 60 Questions; 90 minutes

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 course and exam description, which you 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. Total scores on the multiple-choice section are based on the number of questions answered correctly. Points are not deducted for incorrect answers and no points are awarded for unanswered questions.

Section II: Free Response Questions — 7 Questions; 105 minutes

Long Free Response — 3 Questions Short Free Response — 4 Questions

Section II contains two types of free-response questions (short and long), and you will have a total of 105 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. You will be allowed to use a scientific calculator on the entire free-response section of the exam. Additionally, you 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.

AP Exam Scores

The Readers’ scores on the free-response questions are combined with the results of the computer-scored multiple-choice questions; the weighted raw scores are summed to give a composite score. The composite score is then converted to a score on AP’s 5-point scale. While colleges and universities are responsible for setting their own credit and placement policies, AP scores signify how qualified students are to receive college credit or placement:

AP SCORE QUALIFICATION

5 Extremely well qualified and equivalent to an A.

4 Well qualified 4and are equivalent to grades of A–, B+ and B.

3 Qualified and are equivalent to grades of B–, C+ and C.

2 Possibly qualified

1 No recommendation

Topic Outline

The AP Chemistry course is designed to be the equivalent of the general chemistry course usually taken during the first college year. This course is taken with the idea in mind that students will take the AP Exam to receive college credit or placement at the student’s college of choice.  For some students, this course enables them to undertake, in their first year, second-year work in the chemistry sequence at their institution or to register in courses in other fields where general chemistry is a prerequisite. For other students, the AP Chemistry course fulfills the laboratory science requirement and frees time for other courses. Such credit and placement tied to the AP Chemistry exam could lead to students' readiness for and engagement in  the study of advanced topics in subsequent college courses and eventually the achievement of a STEM degree and successful career.

The course centers around six big ideas and seven science practices:

|Big Ideas |Science Practices |

|1. Structure of Matter |1. Drawing, explaining, and interpreting representations |

|2. Bonding and Intermolecular Forces |2. Using mathematics and logical routines appropriately |

|3. Chemical Reactions |3. Asking and refining scientific questions |

|4. Kinetics |4. Designing and implementing data collection strategies |

|5. Thermodynamics |5. Analyzing and evaluating data |

|6. Chemical Equilibrium |6. Making predictions and justifying claims with evidence |

|  |7. Connecting chemistry concepts across the big ideas. |

Chemical Calculations- The following list summarizes types of problems either explicitly or implicitly included in the preceding material. Attention should be given to significant figures, precision of measured values, and the use of logarithmic and exponential relationships. Critical analysis of the reasonableness of results is to be encouraged.

1. Percentage composition and Empirical and molecular formulas from experimental data

2. Molar masses from gas density, freezing-point and boiling-point measurements

3. Gas laws, including the ideal gas law, Dalton’s law and Graham’s law

4. Stoichiometric relations using the concept of the mole; titration calculations

5. Mole fractions; molar and molal solutions

6. Equilibrium constants and their applications, including their use for simultaneous equilibria

7. Standard electrode potentials and their use; Nernst equation and Faraday’s laws of electrolysis

8. Thermodynamic and thermochemical calculations

9. Kinetics calculations

Laboratory Experiments

The differences between college chemistry and the usual secondary school chemistry course are especially evident in the laboratory work. The AP Chemistry Exam includes some questions based on experiences and skills students acquire in the laboratory:

• making observations of chemical reactions and substances

• recording data

• calculating and interpreting results based on the quantitative data obtained

• communicating effectively the results of experimental work

Students who take the AP Chemistry course, designed with this curriculum framework as its foundation will develop a deep understanding of the concepts within the big ideas through the application of the science practices in the required laboratory component of the course. The course facilitators are expected to devote 25 percent of instructional time to students performing a minimum of 16, hands-on lab investigations to support the learning objectives in the curriculum framework. Additionally, teachers are expected to provide guided inquiry-based labs for at least six of the aforementioned 16 lab investigations. The result will be readiness for the study of advanced topics in subsequent college courses — a goal of every AP course.

Some of the topics for labs include:

-Determination of the formula of a compound

-Determination of the percentage of water in a hydrate

-Determination of molar mass by vapor density

-Determination of the molar volume of a gas

-Standardization of a solution using a primary standard

-Determination of concentration by acid-base titration, including a weak acid or weak base

-Determination of concentration by oxidation-reduction titration

-Determination of mass and mole relationship in a chemical reaction

-Determination of the equilibrium constant for a chemical reaction

-Determination of appropriate indicators for various acid-base titrations; pH determination

-Determination of the rate of a reaction and its order

-Determination of enthalpy change associated with a reaction

-Separation and qualitative analysis of cations and anions

-Analytical gravimetric determination

-Colorimetric or spectrophotometric analysis

-Separation by chromatography

-Preparation and properties of buffer solutions

-Determination of electrochemical series

-Measurements using electrochemical cells and electroplating

-Synthesis, purification, and analysis of an organic compound
