Chemistry Course Syllabus Mr. Shakeri Room D204 Canyon Crest Academy kaveh.shakeri@sduhsd.net 858-350-0253 x4134 Course Description Advanced placement chemistry is designed to be the equivalent of the general college chemistry course. Chemistry is the study of atoms and molecules and how they interact according to physical laws. Chemistry is applicable to everyday life and such connections will be demonstrated throughout the course. This course will focus understanding chemistry through solving problems. The California State Standards below will be covered through demonstrations, discussions, class assignments and laboratory investigations. Atomic and Molecular Structure Chemical Thermodynamics Chemical Bonds Reaction Rates Conservation of Matter and Stoichiometry Chemical Equilibrium Gases and Their Properties Organic Chemistry and Biochemistry Acids and Bases Nuclear Processes Solutions Textbook General Chemistry Ebbing, Gammon Houghton Mifflin, 2005 8th Edition Your success in the course will directly reflect on the amount of time and energy you put into it. Here are some helpful hints for success. Come to class prepared daily and on time. Participate actively and ask questions, routinely check class website. Keep detailed notes about demonstrations and examples presented in class. Keep up with all assigned work and sample problems and read chapters as they are assigned Be open to a variety of learning styles and activities Be able to work productively in groups and independently. Materials: Please bring the following materials to class daily: Scientific calculator or graphing calculator – it should be able to perform logarithmic and exponential functions, as well as scientific notation. Blue/black pen, #2 pencil, and ruler. Chemistry spiral notebook (that has 3 hole punch) or loose leaf paper for notes Highlighter and colored pencils (optional) Grading The grades that students receive in the AP Chemistry course are independent of the grades received on the AP Chemistry exam. Each assignment will have a point value all points are equal. 100 – 90% A 89 – 80% B 70 – 79% C 60 – 69% D 59% and below F The grades are based on a point system. Every point is equal. Different activities will have different point values. The following breakdown gives an estimate to how those points will be distributed during the course. Tests Quizzes Labs Homework Extra credit ~45% (some exams may have curves) ~20% ~30% ~5% minimal if any Grades will be posted on ParentPortal and will be up to date. You may always contact me with email or come in at lunch, before or after school to discuss your grade. I will not discuss grades during class time. Homework There is always homework to do for AP Chemistry. The bookwork is assigned on a chapter basis. Each chapter will be covered in 3-5 class periods, you are expected to pace yourself so all the work does not fall onto one night. Laboratories Laboratories are used to reinforce topics covered in class or to introduce a new topic. The labs will need to follow the laboratory guidelines. There will be at least one lab per unit as time permits. Good lab practice is essential to report data with great confidence and accuracy. Each student will submit their own labs with their own individual thought, data maybe shared within a group. Making up labs will be made up at discretion of the instructor, due to availability of materials. Alternative assignments may be used in place of missed labs. Class Rules: 1) Respect and Common Courtesy 2) Safety Rules will be enforced to the highest degree. Any infractions will be dealt with in a severe manor. Some first time offenses may result in removal from lab activities and possible further administrative repercussions. You will sign and return a safety contract, you are expected to follow these rules. 3) I will enforce all rules as followed by the Canyon Crest Discipline policy. (Academic Honesty, Tardy and cell phones) Consequences: Managing a safe and effective classroom is my number one priority. Students who consistently break rules are a distraction to everyone's education and safety. Infractions will be dealt with by: 1. Warning and/or call home 3. Removal from class and call home 2. Detention and/or additional projects and/or call home 4. Referral to the Vice Principal and call home These steps need not occur in this order, dependent on the severity of inappropriate behavior. Alternative actions may be taken and are reserved for the discretion of the teacher. Absence If you are absent on the day of a test you need to be prepared to take the test on the day you return. If you are absent the assignments due the day you were absent are due the day you return. Any labs, assignments or homework covered when absent are given three days to make up work. If you are absent YOU ARE RESPONSIBLE to find out what you missed while you were out. You may use email to reach me our other classmates; You may also use your lab partner or other “class buddy”; You may also use the class website to find out what you missed while you were away. *****If your absence is unexcused then you will not be allowed to make up any missed test, labs or turn in any work.******* Website: Access is available through the CCA homepage or http://teachers.sduhsd.net/kshakeri/. I add my notes, handouts, practice AP test questions and any other forms I give out in class as I create them. We will also use blackboard. Blackboard will be used for take home quizzes for the chapters. We have a facebook group for students. Students are encourage to chat with classmates and post questions. The facebook page is an extension of the classroom. Only students enrolled in class are permitted in the group. All school and classroom behavior expectations are expected in the facebook group. Late Work Late work will be accepted up to one day after the assignment due date and will automatically loose 50% credit. Late assignments should be handed directly to the instructor either before or after class. Tardy Policy If you are not in your seat before the final bell, you will be considered tardy. A tardy will follow with the school wide consequences. Academic Dishonesty A student who commits or facilitates cheating will be referred to the Administrative team at Canyon Crest Academy. The student will receive a zero for the assignment and will not be allowed to make it up. A second occurrence of cheating will result in a failing grade for the quarter. Open Door Policy I will be available for help everyday usually in the mornings (by 7:30am). My room is open at lunch, but this is usually when I need to take a break and eat some food. Do not expect tutoring during lunch time. You may be able to catch me at the beginning of lunch. I have a free 4th period. My room will be open this time to study and get school work done. I will have tutoring time after school Monday-Thursday for up to 30 minutes or so after school. There will be weekly study session in AP chemistry. The time and date is still undecided, most likely Thursday or Wednesday after school.. I encourage students to meet with classmates to work on homework, study for tests and any other chemistry related material. The times will change according to my travel schedule for my Master’s program schedule. ALL STUDENTS ENROLLED IN ADVANCES PLACMENT CHEMSITRY ARE EXPECTED TO TAKE THE AP EXAM IN MAY!

Purpose: A summary of the concepts involved in the chemical process of the lab. Background Information: This area contains the pertinent information needed to answer the most of the conclusion questions. Often, a historical perspective is provided or chemical equations/reactions are shown. This should give a preview of the laboratory experiment. Procedure: The steps you should follow in order with careful attention to detail. How well you carry out each step will determine the accuracy of your data. Safety: Identify the safety concerns that will be addressed in the laboratory. Include 5 safety rules and specific safety concerns. Materials: Not required if you have a detailed procedure. Data Table: The data table has a title that describes the information recorded in the table. It should contain neat (use a ruler) column and row headings. If a table is not provided, you will have to draw one. Units (ºC, mol, g, mL, etc.) must be recorded with each piece of data recorded in the data table or in the parentheses provided at the top of the column. Use correct significant figures and scientific notation No fractions, only decimals! Data Analysis: This section is where math calculations and graphical analysis are made using data collected from the lab. All work must be shown with equations for credit. You will get an automatic revisit for this section if your work is not shown. 1) Write all calculations in this section. One sample calculation is needed where the same calculation is repeated. Make sure the equation is written, numbers are plugged into the equation with units and final answer represented with units and proper significant figures. All graphs must have a title (X vs Y for (name of the lab)) Each axis must be labeled with the quantity and units. Draw a best-fit line or best-fit curve. Use the whole graph! Staple the graphs to the back of your lab write-up. Conclusion: This section contains questions that test your understanding of the lab and the concepts involved. In a few paragraphs a. Was the lab successful, was your data acceptable (precision, accuracy, reliability) discuss percent error in mentioning the lab’s success. State your purpose and apply background information on the lab to discuss the lab’s success. b. Relate the information to the concepts you are studying. Discuss the patterns of the graphs how they relate to the concept. If there is no graph, use the data to help explain the concept. Error Analysis (Sources of Error): This is the last section where you explain what errors were committed during the lab. No experiment is perfect. There is always some fault, whether it is human error or scientific error. Include as many possible sources of error although only 3 are required. You should explain how your errors impacted the data What could be done to improve the experiment next time. Any follow up questions: Include all discussion questions associated with the lab in the end. Write the question (or summarize) and answer in complete sentences. Miscellaneous Information: 1. Put your name (first and last) and period legibly in the upper right hand corner of your lab. Your partners name goes underneath 2. Do not use white-out! If you make an error, simply put a single line through the error and write the correct information either above the error or to the side of an error. 3. Skip a line between each section of the lab report. 4. Excessive sloppy reports will lose points (i.e. illegible writing or no name). You will not turn in printed data tables, etc. You will use a ruler to neatly write all reports. 5. No more than 2-3 persons in a group.
