AP CHEMISTRY COURSE SYLLABUS

INTRODUCTION:

This course syllabus has been designed to meet first and foremost the directed standards set out by the Collegeboard. Secondarily, the course syllabus has been designed to articulate with the PSI (Progressive Science Initiative) course layout available through the NJCTL (New Jersey Center for Teaching and Learning). To that end, corresponding PSI units have been indicated.

COURSE TEXT: (CR1)

Masterton, William L., Cecile N. Hurley, and Edward Neth. Chemistry: Principles and Reactions. 7th Edition. Pacific Grove, CA: Brooks/Cole Thomson Learning.

SUPPLEMENTARY MATERIALS:

1. PSI AP Chemistry presentations, assessments, homework, classwork, and labs.

2. Zumdahl, Steven, and Susan Zumdahl. Chemistry. 9th Edition. Boston: Houghton Mifflin.

COURSE DESCRIPTION: (CR2)

This AP Chemistry course is designed to be the equivalent of the general chemistry course usually taken during the first year of college. For most students, the course enables them to undertake, as a freshman, second year work in the chemistry sequence at their institution or to register in courses in other fields where general chemistry is a prerequisite. This course is structured around the six big ideas articulated in the AP Chemistry curriculum framework provided by the College Board. [CR2] A special emphasis will be placed on the seven science practices, which capture important aspects of the work that scientists engage in, with learning objectives that combine content with inquiry and reasoning skills.

LABORATORY COMPONENT: (CR7, CR6 - guided, inquiry based experiments in bold in curriculum to follow)

Required Materials:

Graphing calculator, splash proof goggles, and a carbon capable laboratory notebook

Labs:

The labs completed require following or developing processes and procedures, taking observations, and data manipulation. See specific labs within units for details. Students communicate and collaborate in lab groups; however, each student maintains their own lab notebook and is assessed both formatively and summatively on each laboratory experience. A minimum of 25% of student contact time will be spent doing hands-on laboratory activities. [CR5a]

Laboratory Reports [CR7]

A specific format will be given to the student for each lab. Students must follow that format and label all sections very clearly. AP Chemistry lab experiences require more time, analysis, measurement, and materials than a typical first year chemistry laboratory. The seven science practices will be emphasized throughout the experience and the students are required to communicate their procedure and results in a manner consistent with those practices.

Pre-Lab Work:

Each lab will be accompanied by pre-lab instruction including formative assessment questions. Students must perform satisfactorily on these assessments before moving to lab.

Title

Students will recognize that scientific papers have titles. The title should be descriptive. For example, “pH Titration Lab” is a descriptive title and “Experiment 5” is not a descriptive title.

Date

Students will recognize that scientific papers are dated. This is the date the student performed the experiment.

Purpose

Students will recognize that there is a goal to every scientific investigation - a question to be answered. A purpose is a statement summarizing the “point” of the lab.

Procedure Outline

Students need to write an outline of the procedure. They should use bulleted statements or outline format to make it easy to read. If a student is doing a guided inquiry lab, they may be required to write a full procedure that they develop.

Embedded Lab Questions

Students will be given some questions to answer before the lab is done. They will need to either rewrite 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 lab report. It is important to produce a good record of lab work.

Data Tables

Students will need to create any data tables or charts necessary for data collection in the lab

Data

Students need to record all their data directly in their lab notebook. They need to label all data clearly and always include proper units of measurement. Students should underline, use capital letters, or use any device they choose to help organize this section well. They should space things out neatly and clearly.

Calculations and Graphs

Students should show how calculations are carried out. Graphs need to be titled, axes need to be labeled, and units need to be shown on the axis.

Conclusions

This will vary from lab to lab. Students will usually be given direction as to what to write, but it is expected that all conclusions will be well thought out and well written.

Post Lab Error Analysis Questions

These questions will aid to develop insight into the lab, the analysis of data, and some reflection as to the source of error in the experiment.

Post Lab Assessment

Each lab will have it’s assessment to measure student comprehension and skill and their application of the appropriate science practices.

**Advanced Placement Chemistry — The Laboratory Notebook CR7

A record of lab work is an important document, which will show the quality of the lab work that students have performed and the student’s ability to communicate to others.

COURSE ASSESSMENTS:

Tests: There will be full length unit tests consisting of both multiple choice and free response questions meant to simulate the Collegeboard questions in scope, objective, and style.

Quizzes: There will be multiple quizzes for each unit consisting of both multiple choice and free response questions.

CW/HW: For each unit, extensive classwork and homework is assigned. The completion of this is required but is not part of the students’ evaluation.

Laboratory Reports and Quizzes: Each laboratory will be assessed by means of a post-lab quiz which will require students to communicate their scientific reasoning and apply the science practices to laboratory situations. A laboratory notebook is required to be kept by all students.
