AP CHEMISTY SYLLABUS OVERVIEW OF AP CHEMISTRY COURSE CLASS MATERIALS: You will need to bring to class EACH day: textbook (“Chemistry“by Steven Zumdahl, 7th Ed), a 3ring binder, spiral notebook, calculator and a pencil or pen. A separate laboratory notebook is also required. A TI-84+ graphing calculator is used extensively in class and it is suggested that you purchase your own as the classroom set is not available for checkout. COURSE DESCRIPTION: This course meets 5 days a week for one 50 minute Period each day with lab days to extend for one hour after or before school on an average of one day ever other week to allow additional time if required by students. The A.P. Chemistry course is designed to be the equivalent of a General Chemistry course taken in college. Upon completion of this course, students will be prepared to take the AP Chemistry test. A score of 4 or 5 on the test COULD result in advanced placement or General Chemistry credit upon entrance into college (depending on the institution). Students will receive a sequentially planned A.P. Chemistry program designed by the College Board for A.P. Chemistry classes. The course includes manipulation of materials, experimentation with written labs, problem solving, class discussions, and lecture. By design, this course is more rigorous than high school chemistry, because of the type of text used, topics covered, emphasis placed on chemical calculations, formulation of principles, and the emphasis placed on labs and written reports. It is strongly recommended that students take the Honors Chemistry course as a prerequisite for this course because several of the required AP labs are integrated into that course. EXPECTATIONS: Do you want to learn? Will you do the work necessary to be prepared for class everyday? If so, then you are in the right class! All of you have taken at least 3 science courses by now. Your academic responsibilities will include doing ALL of the reading, problem sets, and most lab reports outside of class. You will have at least one hour of homework every night. This is a college level course and you will be treated as such. The more prepared you are to learn, the more you will. Each chapter you will be given a calendar outlining due dates for your assignments and labs along with test dates. This is a very fast-paced class with fairly inflexible deadlines. Before the AP Examination in the spring there will be 2 weekend optional review sessions where you will have the opportunity to complete a full AP Exam under AP exam conditions. All students are required to take the actual AP Chemistry exam to receive credit for the course. After the Exam in May, the remaining 2 - 2 ½ weeks of school will devoted to select special topics in chemistry. BEHAVIOR: As for behavior, RESPECT is the name of the game. If you can’t follow the rules, you can’t play the game. 1) All students are expected to be in class on time and prepared to work. 2) Since this an advanced Lab course students may be working on various activities and labs during the same period. Therefore, responsible and safe behavior will be expected at all times. If a student has demonstrated that he / she can not conduct themselves in a responsible manner he /she will be removed from the class permanently. 3) Students will work in small lab groups and will be expected to contribute to the groups’ work in an equitable manner or will be removed from the group and be required to complete all lab work by themselves. 4) All students must continue to show a desire to work at an AP level or a parent conference will be requested. If this meeting fails to produce the desired results the student will be referred to the guidance office for further action. 5) All other school rules and policies will be adhered to and violations will result in appropriate consequences as outlined by the student handbook. EVALUATION: Notebooks; SAVE ALL PAPERS! You may need them to verify a grade or for college interviews. The papers should be arranged in chronological order. These papers will ultimately serve as the basis for your science portfolio. Labs and Demonstrations; You will perform the twenty two major labs that are recommended for the AP Chemistry Course along with a few others that will enrich your understanding of chemistry.. It is very important to be very detailed and thorough when conducting a lab. You will be expected to follow a specific format when writing up the data from the experiment in your lab report. Failure to adhere to lab safety and conduct rules results in immediate removal from the lab and no credit. Different concepts and process skills will be assessed for each lab along with appropriate lab conduct. Labs conducted in Honors Chemistry will be referenced in this course. You will work in small lab groups where collaboration is expected but individual typed lab reports are required. Although a satisfactory Lab report is required for each lab the lab score will not be averaged into the final grade but will result in a grade letter reduction for each unacceptable lab. Lab Notebook; Since a typed lab report will be required for all labs, you will not need a special laboratory notebook. A bound composition notebook will be required in the labs to record lab notes and data. No loose sheets of paper to write notes on will be tolerated. Text Problems & Practice Tests; You will be given nightly problems from the chapter and daily assessments will be used to determine comprehension of the materials. All work is for your benefit and your benefit only. Assigned Text problems will be representative of the rigor of the questions expected on both the chapter test and the AP exam. The type of resources such as calculators and reference charts will be limited by the rules for the AP exam. Appropriate past AP tests questions are given the day before a chapter test for additional test preparation. Late work; NO CREDIT IS GIVEN FOR LATE ASSIGNMENTS. If an assignment is checked in class, it is due at that time, not at the end of the period. If the assignments are turned in for me to grade, I must have it by the end of the day. Tests & Quizzes; Tests will be given at the end of each chapter or unit. The test is composed of multiple choice and free response questions from AP Released exams. They are timed and scored in the same fashions as the AP Exam. There is usually a comparable retake test, but you are required to come in and make corrections to your original test first to show you have a better mastery of the material before retaking the test. During the second quarter, Ion quizzes will be given twice a week. Reaction equation quizzes are given once a month starting the 2nd quarter along with monthly Ion review quizzes. Expect the mathematical questions to be common, rigorous and representative of the topic being covered. If you miss a test or need to take a retest, you will make it up before or after school, NOT during class. Tests are worth 100% of the total grade with retest scores totally replacing original scores. Grading Scale; The grading scale is based on percent scores- NOT TOTAL POINTS! To earn an A you must demonstrate 100 - 85% proficiency in completing the assignment, activity, lab, or test. 84-70% is a B, 69-60% is a C, and 59-50% for a D. Quarters are weighted equally with the midterm and final exam carrying the school’s prescribed weight. There is no extra credit!
