Syllabus for AP Chemistry Teacher: Mr. Lambert Room: M101 Textbooks: General Chemistry 4th Edition. John W. Hill, Ralph H. Petrucci, Terry W. McCreary, Scott S. Perry. Pearson Prentice Hall, 2005. ISBN: 0-13-140283-8 Laboratory: Labs are used or adapted from the following: Laboratory Experiments for Chemistry: The Central Science. John H. Nelson and Kenneth C. Kemp. Prentice Hall Publishing, 2000. ISBN: 0-13-084101-3 Laboratory Investigations: AP Chemistry. David Hostage and Martin Fossett. Peoples Education, 2006. ISBN: 14138-0489-6 Objective: The objective of this course is to build on the foundation of chemical knowledge developed in the first year course by strengthening the student’s basic understanding of chemical concepts, such as atomic structure, gases, chemical kinetics, chemical equilibrium, and thermodynamics. This course aims to: 1) provide the students with a basic understanding of chemical concepts in a manner that is equivalent to a first-year college chemistry course; 2) provide students with a safe and enjoyable learning environment where they feel free to express their ideas, ask questions, and offer answers; 3) strengthen student’s quantitative reasoning and problem-solving skills; 4) promote team-building skills through collaborative laboratory exercises; 5) teach students how to work quickly and effectively when presented with a difficult problem; 6) help students express their answers to theoretical questions clearly and concisely; and 7) develop independent thinkers that are curious about the scientific world around them. Method of Instruction: The majority of the information is presented in a lecture/discussion setting. Throughout the class period, questions and problems will be presented to the student directed towards strengthening their understanding of the topic of discussion. The solutions to these questions and problems are discussed using as much student input as possible. Laboratory experiments are performed approximately once a week during a 60 minute block. At this time, student will: 1) directly examine the concepts discussed in class; 2) learn and use the fundamental skills required to perform chemical experiments; 3) gather and analyze data collected during experiments; and 4) present the results of the experiment in a clear, concise manner. The procedure, any data a student collects, and the analysis of that data for a given lab will be kept in a formal laboratory notebook. Method of Evaluation: Your grade in this class will determined through your performances on unit tests, weekly quizzes, and homework. Every student who takes the class is encouraged to take the SAT II Chemistry subject test, but they are required to take the AP exam. a. Tests: Tests will make up 55% of the semester grade. All tests will be weighted equally. There will be a test at the completion of each unit of study. Each test will be broken down into two sections: multiple choice and free response. Each section will have a time limit. You will start with the multiple choice section. At the end of the allotted time, I will collect the multiple choice section and hand out the free response section. Calculators may only be used on the free response section. b. Quizzes: Quizzes will make up 25% of the semester grade. You will encounter three types of quizzes in this class: in-class, take-home, and lab. In-class quizzes will be closed-book, and most will be multiple choice. The take-home quizzes will be adapted from past AP free response questions dealing with the current topic of discussion. These quizzes will be open-book, open –note and will be collected at the start of the next class period. Lab quizzes are designed to evaluate the student’s understanding of the procedure, data manipulation, and results analysis. The quizzes will also be take-home and collected at the start of the next class period. If you are not finished with your take-home quiz, you may ask to leave class to finish it. If you choose to do this, there will be an automatic 5 percentage point penalty on the quiz. If you do not hand in the quiz by the end of the class period, there will be an addition 5 percentage point penalty AND you will be reported as having an UNEXCUSED absence from class. c. Problem Sets: Problem sets grades will make up the final 20% of the semester grade. Selected questions from the problem set will be due the day after the completion of a section within each unit. These questions will be graded for correctness. In order to earn full credit on the problem set, you must show all your work for every question. THERE ARE NO ONE-WORD ANSWERS IN CHEMISTRY, even though the question may appear to be asking for one. Always explain your answers. If you are having problems, you’ll need to see me outside of class. d. Extra Credit: Extra Credit can be earned for each unit test. This is an optional exercise although it is one that I highly recommend. The amount of extra credit given will vary from test to test, but it will be at least 5 points. Class Expectations: 1. You should always be prepared for class and ready to begin working as soon as the bell rings. We have a lot of material to cover, and I always look forward to seeing your smiling faces. If the door is closed upon your arrival to class, it means that you are tardy. If this occurs more than 5 times over the course of the year, I will double your minutes when I report them to the Dean’s office. Message: Don’t be late! 2. You should keep all notes, handouts, worksheets, homework assignments, tests, and quizzes together in one location, preferably in a 3-ring binder that should be specific for this class. Since this is an AP course, the expectation is that you will master all the material that is covered in the course. In order to master this material, you WILL have to review it, which is why all your material should be located in one place. 3. You are required to bring a calculator to class. We will be working through a lot of problems in class. Failure to bring a calculator to class will result in tardy minutes as I will make you go and get your calculator. 4. You are expected to read your textbook, even though you may not be given specific reading assignments. Your textbook is a great resource, use it. 5. You will treat everyone in the class with respect. This is a hard class, and I know that there will be a lot of questions. Everyone should feel free to ask those questions and participate in class. If, at any time, I feel you are being disrespectful to me or your classmates through your words or actions, I will ask you to leave class (and you will have to deal with the consequences of being dismissed from class). 6. The laboratory is a serious place, and I take it seriously. No horseplay will be tolerated. I expect you to wear you lab goggles at all times. If labs are not completed in the allotted class time, you will be expected to finish them outside of class. 7. Major assignments, such as lab reports and projects, will drop 1 letter grade everyday they are overdue. If you know you will have a problem making a deadline, please talk to me BEFORE the assignment is due. 8. A test or a quiz may be postponed 1 day if you arrive back on campus after 8:30 p.m. from a SCHOOL TRIP the night before the test is to be taken or the quiz is due. I will expect you to make up the test the following day either in the morning before classes or during a free period (take-home quizzes will be due the following day at the start of class). 9. You are expected to make up a missed quiz or test (due to an excused absence) at some point the following day. It is YOUR responsibility to set up a time with me to make up the missed work. Failure to do so will result in a zero in the grade book. In the case of unexcused absence, you will receive a 0 on any work due that day, including any tests or quizzes taken during the class period. 10. You are expected to follow all the school’s policies set forth by the Honor Council and in the Student Handbook. 11. I will allow food and drink into the classroom if it does not disrupt the class. Absolutely no food or drinks will be allowed in the laboratory area. The classroom is not a garbage can. Clean up after yourself. This is a privilege, not a right. If you abuse it, it will be taken away. 12. I’m happy to give extra help. I will be in my classroom every morning by 7:15 am. Come see me!
