This Advanced Chemistry Course Is designed to be the equivalent of the general chemistry course taken during the first year of college. Students successfully completing this course will be endowed with an exceptional understanding of the fundamentals of chemistry and achieve proficiency in solving chemical problems. This course will contribute to the development of each student’s ability to think critically and to express his/her ideas, in both oral and written fashion, with clarity and logic.

Students must be disciplined, self-motivated and Industrious. Course Objectives: Quantitatively and qualitatively describe matter and its changes by applying concepts of liquids, solids, gases, solutions, chemical reactions, atomic theory, chemical bonding, nuclear chemistry, stoichiometry, equilibrium, kinetics, and thermodynamics. Apply and analyze chemical concepts through chemical calculations such as percent composition, molar masses, empirical formulas, gas laws, mole fractions, chemical kinetics, and standard electrode potentials and their use. ? Create, conduct, and analyze the laboratory experiments to engage and reinforce learning of concepts taught throughout the course. ? Demonstrate critical and independent thinking and an appreciation for the natural world. Grade Scale: The DA grading scale as follows: A 100-93 A92-90 8+89-87 B 86-83 882-80 C+ 79-77 76-73 72-70 69-67 66-63 62-60 59 or below Grading: All significant assignments will have written instructions including due dates and clear expectations.

Refer to the course overview for further grading breakdown. Classroom Policies: This class will follow the DA discipline plan as described in the handbook and discussed during orientation. Students who misbehave will be given a green or red card, be excused from class, and be expected o email their parents about whatever behavior issue they struggled with. Drop Date: The last day to drop a DA course (without Incurring a W [withdrawal] on your transcripts) is October 5th. Please pay careful attention to this date.

Upon completion of Advanced Chemistry students will be able to Quantitatively and qualitatively describe matter and its changes by applying concepts of liquids, solids, gases, solutions, chemical reactions, atomic theory, chemical bonding, nuclear chemistry, stoichiometry, equilibrium, kinetics, and laws, mole fractions, chemical kinetics and standard electrode potentials and their einforce learning of concepts taught throughout the course. Attain an acceptable score on the College Board AP Chemistry Examination Demonstrate critical and independent thinking and an appreciation for the natural world.

Laboratory Laboratory investigation is a central pillar of the AP Chemistry course. Labs will include an emphasis on experimental procedures. Each week students will spend approximately two hours devoted to lab work outside of normal class time. Much of the laboratory work requires the use of experimental apparatus including volumetric glassware, such as pipettes and burettes. Students will gain experience with iltrations, titrations, collection and handling of gases, colorimetry, potentiometric measurements, and synthesis of compounds.

Some of this laboratory work will also involve the analysis of unknown compounds either by individually devised schemes or by systematic qualitative analysis. Students are required to complete a report for each lab experiment, including an a priori hypothesis, lab procedure, documentation of observations/data, demonstration of calculations, and a conclusion. All reports are kept in a well-organized, easily reviewed, quad-ruled, permanently bound notebook (no spiral notebooks, please! ) Materials a. . c. d.

Nelson, Kemp Laboratory Notebook quad ruled A graphing calculator will be extremely useful however not required typically be checked at the beginning of class. For full credit you should show all work including formula units, significant fgures (where applicable) and answers must be boxed. Tests and Quizzes There will be numerous short quizzes on topics covered in class. There will also be essay exams and unit tests that go along with each unit covered in class.

Essay exams (or free response exams) will be derived from College Board free response exam questions and graded according to the College Board standards. Grading The grading points are divided up into three categories: Formative and Summative assignments each weighted at 37. 5% of the student’s grade and the semester exam which is weighted at 25% of the student grade. The point values are as follows: Assignment type point value Homework (formative) 5-30 points Quizzes (formative) 5-30 points Tests (summative) 100 points Labs (formative & summative) 30 points Semester Exam 100 points Course Outline AP Chemistry l.
