AP Chemistry 2007-2008 Instructor: Room: Phone /E-mail: Mr. Paul Birkenfeld 324 662-2509 / paulb@cksd.wednet.edu Course Overview: A.P. Chemistry a college level course, which requires students to put forth their best effort on a daily basis, both in and out of class. In this course, the student will cover a complete exploration of chemistry with emphasis on: matter and measurement; atoms and elements; molecules-ions-compounds and their nomenclature; stoichiometry; electron configurations and periodic trends; atomic models and molecular structures; bonding and intermolecular forces; properties of gases, liquids, solids and solutions; chemical kinetics; chemical equilibrium; chemical thermodynamics (free-energy, enthalpy and entropy); electrochemistry; nuclear chemistry and descriptive chemistry of the elements, including some organic chemistry. Chapters 1-21 and 23 of Kotz & Treichel’s Chemistry and Chemical Reactivity (Fifth Edition) encompasses the entire course of study. The use of mathematics as a tool in problem solving and in derivations is expected to play a dominate role in the course. Time spent outside of class on textbook problems, reading, formal laboratory write-ups, advanced placement problem sets, and studying is typical for a student enrolled in the course. The hands-on laboratory component of this course is essential in the student’s understanding of the concepts and applications of chemistry; at least one question on the A.P. Exam focuses on the laboratory experience. Students are encouraged from the first day of class to form a study group to work with in and out of class – student success is improved through cooperative study groups! Course Goals (abbreviated from 2006-2007 College Board AP Physics Course Description): Students should… Read, understand, and interpret chemical and physical information and problems Use the scientific method to analyze particular chemical and physical phenomenon or problem. Use basic mathematical reasoning in a chemical or physical situation or problem Design and perform hands-on experiments, interpret the results of observations and communicate including uncertainty assessment Text books and Materials: Chemistry and Chemical Reactivity -Fifth Edition, by John C Kotz and Paul M. Treichel Jr. (© 2003. Thompson Learning, Inc.) A scientific calculator and three ring binder with dividers is mandatory. It is required that students keep (in a neat and organized fashion) all materials collected throughout the semester: Syllabus, Notes, Homework, AP Problem Sets, Laboratories (Portfolio of Completed Formal Lab Write-ups), Quizzes, Exams, Final Exam. These will be kept in a three ring binder. These may or may not be graded for organization and completeness at any time (announced or unannounced) throughout the school year. Grading Policy: Quizzes Tests Labs and Problem Sets Overall percentages: 93% - 100% = A 90% - 92% = A85% - 89% = B+ 80% - 84% = B 40 % 40 % 20 % 75% - 79% = B70% - 74% = C+ 63% - 69% = C 60% - 62% = C- 55% - 59% = D+ 50% - 54% = D 0% - 49% = F Class Website: All the materials for the course can be downloaded from the website. It is your responsibility to visit the site to get materials as they are needed. You are required to visit regularly. http://www-ckhs.cksd.wednet.edu/Mr%20b%20Web%20Page/HOME.htm Course Notes: Notes be available on-line from the class website. Course notes amplify the content of the whole course. The notes are vitally important to students as they form a permanent, hard copy record that summarizes of all the knowledge and understanding that students will need to acquire in order to perform well on the AP Chemistry Examination. These objectives and notes should be downloaded, printed, and ready for use at the start of each unit. Each set of notes should be completed in class and annotated however the student sees fit. They should be used as the basis for continual study. Failure to do this may make it hard for a student to keep pace with the lecture/notes being reviewed in class. 1 Assignments/AP Problem Sets: Reading from the textbook, reviewing notes, and taking advantage of outside resources is highly recommended. Although most problems are found within the notes, textbook problems/questions may be assigned up to two or three times a week consisting of about five problems that may or may not graded. It is imperative that you take your daily class assignments seriously so that you can get the most out of the lecture in the next arranged class meeting. A.P. Problem Sets, which will be graded, are generally assigned over a weekend and/or at the end of a unit. All problems (whether multiple choice or free-response) involving calculations must have work shown completely. For essay or short answer questions, answer questions in complete sentences. It is the student’s responsibility to ask questions about homework, problem sets, or other information they don’t understand. Laboratories: Hands-on Labs will be performed in class, requiring advanced reading, and followed up by a formal lab write-up. Our lab write-up will be similar to what is required by Washington State University Physics students (See Appendix A). All labs must be typed and strictly adhere to the model provided to receive full credit. A portfolio of the completed labs must be retained by each student. Missed laboratories must be made-up the Friday of the week that the laboratory was missed. It is the students responsibility to arrange this with the instructor. Quizzes: Quizzes can consist of both multiple choice and free-response like questions. Most quizzes last a full class period, usually given on a Friday, and being returned on Monday. I might try short daily quizzes, rather than weekly quizzes, in an attempt to improve student learning. Quizzes may contain extra points (extra credit), and are directed at the concepts and basic knowledge over newly learned material, where as, tests involve multiple concepts, and will include previously tested material in their questions. Missed quizzes must be made up before the next class meeting, best if done in the library before school. If a prolonged absence of more than two days takes place, arrangements will be made on a student to student determination by the instructor, on how the missed quiz will be handled. Classroom Expectations: Attendance, punctuality, courtesy and good behavior of the highest levels are expected at all times whether in lecture or laboratory. Laboratory safety is always of paramount importance. Your exemplary behavior and observance of safety procedures is required at all times (or you may lose lab privileges). Students are asked to… - give the instructor their undivided attention - respect the right of other students to study and work in peace. - come to class on time, prepared to do class work, and/or participate in class discussions. - handle all chemicals and lab materials in a safe manner. - handle all equipment with care and returned to where it came from. - follow all instructions provided at the start of a laboratory - respect others and their property. - not bring any food or drink (including water) into the classroom. - sign-out of class and pick-up the hall pass prior to leaving the classroom” - follow the “nice or neutral” policy when interacting with others. Furthermore… Absolutely no form of cheating will be tolerated (copying work, allowing work to be copied, copying exams or quizzes, allowing exams or quizzes to be copied, plagiarism, etc…). The Consequences… 1st occurrence : A warning 2nd occurrence : Conference with instructor after class 3rd occurrence : 30 minute after school detention (with instructor), referral to a counselor, and parental contact 4th occurrence : Removal from classroom, Referral to Assistant Principal’s office, and parent conference. 2 Late Work Policy: An assignment or any activity (lab, worksheet, etc…) is considered late if it is not ready to be turned in by the start of class on its due date. Ready to be turned in means stapled and easily accessible. Late work is accepted for up to ½ credit if one day late and is not accepted after that except under extreme circumstances with teacher permission. Due to the pace of this course, material will be covered daily that builds upon material from the day before and leads into material that will be covered the following day. If you are to keep up with the material it is imperative that you attend class daily. If you miss a class(es) it is your responsibility to determine what you missed and complete and submit the missed work. Students found to be truant on the day of a quiz, the day an assignment is due, the day a lab was due or performed, or the day any other work was due or performed will receive a 0 for that work. Any student that accrues more than 10 absences (excused or unexcused) per semester may lose the opportunity to complete any make-up work. A decision of whether or not to provide make-up work lies solely with the instructor. Book Check-out/Check-in Procedure: If you have a text book issued to you, that book becomes your responsibility while you remain enrolled in the course. You are not to mark, write in or damage the text in any fashion. At the time it is issued you will be asked to record the books number and its condition. It is imperative that you record the specific condition of the book at the time of issuance to avoid a fine when you return the book. Books must be turned in to me at the end of the school year OR when you terminate your enrollment in the course or you will be fined according to the fines below. Replacement of Text Book... Book Re-binding... $120.00 $ 20.00 **Getting Extra-Help / Tutoring: Each weekday 7:00—7:45 AM (by appointment) OR Monday – Thursday from 3:30 – 5:00 PM in the CKHS Library. Examinations: Below is a tentative listing of exams taken in the first and second semester. First Semester (18 weeks) Unit One Exam Lab Equipment, Procedures and Safety Unit Two Exam Chapters 1-3 Matter, Measurement, Atoms, Elements, and Compounds Unit Three Exam Chapters 4-6 Stoichiometry, Reaction Prediction, and Thermochemistry (Enthalpy) Unit Four Exam Chapters 7-8 Atomic Structure, Electron Configurations, and Periodicity Unit Five Exam Chapters 9-10 & 13 Bonding and Intermolecular Forces Unit Six Exam Chapters 12-14 Solids, Liquids, Gases, Solutions and Phase Diagrams FINAL EXAM CHAPTERS 1-14 (EXCLUDING CHAPTER 11) Second Semester (14 weeks) Unit Seven Exam Chapters 15-16 Chemical Kinetics and Equilibrium I Unit Eight Exam Chapters 19-20 Thermodynamics (Enthalpy, Entropy, and Free Energy) and Electrochemistry Unit Nine Exam Chapter 17-18 Equilibrium II: Acids, Bases, Salts, Buffers, and Solubility Products (Ksp) Unit Ten Exam Chapters 21 and 11 Nuclear Chemistry and Organic Chemistry 3 Exams are scheduled a week in advance giving the student plenty of time to prepare for the examination. Missed exams involving only a one or two day absence prior to the exam, students will be expected to take the exam immediately upon their return. Longer absences will be handled on an individual basis for each student. If you know your going to be absent the day of the test, try to make prior arrangement with the teacher. Failure to comply with the above may result in a “zero” grade being entered for your score. Remember it is your responsibility to make arrangements with the instructor on when exams can be rescheduled and completed. Lab Experiments: Approximately twenty percent of the course is devoted to the laboratory component of the course with each lab being a hands-on experience for the student. A.P. Chemistry meets five days a week for 57 minutes; averaging about two periods per week for hands-on laboratory experiences. The experience gained by manipulating equipment, recording and organizing data, and drawing conclusions is a critical part of any science course. It is important for the student, using a spreadsheet (MS Excel), to be able to establish relationships between the data collected. This can be done by properly defining the independent and dependent variables, and establishing the best curve or line of best fit by establishing a linear relationship between variables. All labs will be typed following a university format as will be explained in class (see Appendix A). Each student must keep a copy of all labs in their three ring binder, so that they may be presented (in portfolio format) at any university in order to show that they have completed the lab component of their A.P. Chemistry course. If the situation should arise where you need to miss a laboratory for athletics, cocurricular or illness, students must make-up the laboratory after school on the first Friday following the missed laboratory. Other arrangements to make up a missed lab will only be at the discretion of your instructor. Students are expected to follow all lab safety guidelines at all times. Students found not following safety rules may lose credit for that lab and may lose lab privileges for the remainder of the course (resulting in a score of zero for the remaining laboratories).

Note that the percentages given below are rough guidelines. More or less weight may be given in certain circumstances. The lab report should be self-contained so that anyone (not necessarily with a chemistry or physics background!) can read it and understand what you did. General Format Lab reports are expected to BE TYPED and LOOK LIKE COLLEGE LEVEL WORK. Your reports are expected to be free of grammatical, syntax, and spelling errors, and look like a respectable presentation of your work. You are therefore advised to proofread your work before submitting it. Your lab report should generally include the following sections: Title Page (5%) Purpose of Lab (5%) Pre-Lab Questions (5%) Procedure (10%) Experiment Description, and Observations (15%) Analysis (Calculations, Graphs, etc.) (40%) Discussion, Conclusions, and Post-Lab Questions (20%) Each of these components is discussed in detail below. It is your job to present information in a clear, understandable way. The goal is to have a self-contained report that can tell someone without a chemistry or physics background and without a lab manual what you did. As the semester progresses, the presentation aspect of the lab report should improve, so more points may be taken off for excessively sloppy, unorganized reports. Take this opportunity to practice your presentation/organization skills, as these skills will help you in whatever career you choose. Different laboratory exercises may lend themselves to different overall formats. Nevertheless each report must contain some form of the various components listed above. Don’t hesitate to ask your instructor(s) about the appropriateness of a particular format that you wish to use. Title Page (5%) The first page of the lab report is the title page consisting of: The title of the experiment Lab group members names Lab station number The date that the lab was performed The date that the lab was submitted Nothing else should appear on the title page, and the entire report should be stapled in the upper left-hand corner. Prior to handing in a laboratory, all members of a lab group should have reviewed the report and then initialed by their name. This indicates to me that they have read through the report and will accept the grade that it earns. Purpose (5%) Clearly explain the purpose or purposes of the experiment. Why did we do this lab? Pre-Lab Questions (5%) Complete all pre-lab questions clearly showing all work/calculations and using completing complete sentences when answering short answer questions. Procedure (10%) Briefly describe the procedure you followed and draw a picture of the experimental set-up to meet the purpose of the lab. This should include the equipment being used. The procedure section should be adequate so that anyone without a chemistry or physics background could read it and follow along. In other words, someone else could repeat your experiment following the steps outline in your procedure. 13 Experiment and Observation (15%) Record all data in an organized (table format) fashion. Include relevant symbols and appropriate units when recording data. When making measurements please record the appropriate number of significant figures. Analysis (40%) Calculations Complete the calculations outlined in the laboratory in this section. Show ALL WORK for each calculation. If your lab involves multiple trials show ONE complete example of substituting in numerical values (indicate where the numerical values come from, say Table I, run#2, for clarity). If your calculation (s) involves unit conversions be sure to show all conversion factors with units. Display ALL the results of your calculations (tables can be very useful here) including the appropriate units. Graphs If a graph is required for a given lab, each graph is to be done on a separate page OR clearly and neatly inserted into your word document from MS EXCEL (See Appendix B). Each graph must have a title and the axes clearly labeled. Be sure independent data is plotted on the x-axis and dependent data is plotted on the y-axis. If you're asked to draw a curve through your data points, this should always be a best-fit curve (for example, a straight line that best represents your data, not a dot-to-dot connection of data points). If you're asked to calculate the formula that relates your data use MS EXCEL and record the equation on your graph, indicating clearly which points on the graph you used in your analysis. Discussion, Conclusions, and Post-Lab Questions (20%) The discussion section should be three paragraphs in length (with a maximum of one page). It should be carefully organized (you may even wish to make a rough draft outline first!) and must include consideration of ALL of the following aspects of your experiment: results, interpretation of results, and uncertainty in results (see below). Each of these aspects is discussed in detail in the following paragraphs. Your discussion should be written in paragraph form (don’t submit the outline), and you may find it convenient to organize the various aspects differently for different labs. “Consideration” does not simply mean answering each question below, but placing your experiment in the context formed by these questions and reporting your results. Cite specific experimental results liberally to support your conclusions. Not all of the following questions will apply to every lab! Results What is the connection between your measurements and your final results? What were the results of your calculations? If your lab involved graphing variables… What trends were noticeable (linear, inverse, polynomial, exponential) ? Clearly identify the dependent and independent variables used in the lab. How did the independent variables affect the dependent variables? (For example, did an increase in a given measured (independent) variable result in an increase or decrease in the associated calculated (dependent) variable? Interpretation of results What is the theory or model behind the experiment you performed? Do your experimental results substantiate/agree with the theory? (Be sure to refer specifically to YOUR experimental results!) Why or why not? Were these results consistent with your original beliefs, or were you forced to re-evaluate your prior conceptions? Uncertainty in results How much did your results deviate from expected values (percent error)? Are the deviations due to error/uncertainty in the experimental method, or are they due to idealizations inherent in the theory (or both)? If the deviations are due to error/uncertainty in the method what are the possible sources – Be Specific!!! For example, if your value was higher than the true value what could have caused this? DO NOT SAY “HUMAN ERROR” WAS THE CAUSE. If the correct value is unknown or difficult to find, what range of values would seem reasonable for this quantity? Draw on your own experiences or site values for similar material. In which of the measurements or observations that you made do you have the least confidence? How would variations in this value (if it were too high or too low) affect your results? Post-Lab Questions Complete all post-lab questions clearly showing all work/calculations and using completing complete sentences when answering short answer questions 14 APPENDIX B: GRAPHING WITH MS EXCEL 1. Start MS Excel and add data to cells then 2. Select XY Scatter plot, then click next click on the chart wizard (looks like a little graph) 3. Click on “Series” tab then click on “Remove” 4. Click on the “Add” button. 5. Click on the grid button next to the “X Value” 6. Highlight the independent data (X) in your spreadsheet, then close the chart source window 8. Highlight the dependent data (Y) in your spreadsheet, then close the chart source window 7. Click on the grid button next to the “Y Value” 9. Click Next 15 10. Add Chart Title, and Label Axes with variable and units. 11. Unless you have more than one data series remove the legend from the graph 12. Save the graph as a new sheet. 13. To print the equation for the graph on the chart right mouse click on any data point on your graph and select “Add Trendline” 14. Choose the type of regression you wish to use in producing your trendline, then click on the “Options” tab and check that the option to “Display equation on chart” and “Display R squared Value on chart” are checked 15. Edit your equation so that instead of “X” or “Y” the independent and dependent variables (respectively) that you plotted show-up in the equation. 16 APPENDIX C: Central Kitsap High School CLASSROOM GUIDELINES CKHS staff values student behavior that reflects caring, trustworthiness, respect, truthfulness, honesty, and good school citizenship. 1. ATTENDANCE Class attendance is important every day. Any student who misses more than ten (10) days may lose the opportunity to complete make-up work. 2. TARDIES Each student is expected to be in class on time. Tardies will now be tracked on a cumulative basis across each students schedule. See consequences for tardiness listed below. When a student reaches 3 tardies in any one week, he or she will move up one step along the following list for consequences: Step 1: Step 2: Step 3: Step 4: Step 5: Step 6: Warning from ISS Monitor Work Detail assigned by ISS Monitor Double Work Detail assigned by ISS Monitor In School Suspension day assigned by Administrator with phone call home Thursday School(s) assigned by Administrator with phone call home Suspension consequence (out-or in-school) with parent/administrator conference Student tardies will be reset to zero at the end of the semester. 3. PASSES Students need a pass to be in the hallways during class time. Students without a pass will be escorted back to class by security. 4. FOOD/DRINKS NO food or drink is allowed anywhere except the cafeteria and in front of the building. Bottled water is allowed with the teacher’s permission. 5. BEHAVIOR Students are expected to display appropriate behavior and use appropriate language in the classrooms and the halls. Harassment, profanity, and fighting, as well as possession of weapons, will not be tolerated and will be dealt with swiftly and in accordance with district/building policy Walkman or CD players, laser pointers, and/or communication devices such as pagers and cell phones may not be used during school hours. 6. DEFACING SCHOOL PROPERTY Students are expected to respect school property. They are expected to place waste in proper recycling and trash receptacles. Students shall not deface or mark on lockers, desks, tabletops, walls, textbooks, carpeting etc. 7. CHEATING Cheating in any form will not be tolerated. Cheating includes plagiarism and copying another student’s homework or test. Students copying the work and students willingly allowing others to copy their work or test shall be held accountable for cheating; teachers who witness the copying of homework in hallways or other classes will follow-up with the student’s teacher. Suggested district consequences for the first offense of cheating include a seven (7) day suspension from school. 17
