ADVANCED PLACEMENT CHEMISTRY 2012-2013 MR. LINARES ROOM 302 EXT. 221 rlinares@bosco.org Office Hours: Tue. and Thurs. 3-4pm. Please make an appointment GENERAL INFORMATION The course is designed to be the equivalent of a first year college general chemistry course and follows the College Board’s AP Chemistry Topic Outline. It is only for high school students who exhibit high levels of commitment, motivation, and academic maturity. Pre-requisite: One full year of high school Chemistry. Student should be concurrently enrolled in Algebra II or a higher-level math. COURSE OBJECTIVES Students will hone their analytical skills through the use of logical reasoning, critical thinking, written and oral communication, and through using mathematical applications when problem solving. Expectations are that these skills be applied during all aspects of class activity. Through the development of the problem-solving strategies obtained during this course, college-bound students will become better prepared for careers in medical, engineering, and other areas of natural science. Students will gain a greater, and much more in depth perspective and understanding in concepts covered in general Chemistry; the nature, structure and states of matter, chemical bonding and reactions, gases, stoichiometry, kinetics, equilibrium, thermodynamics, electrochemistry, and nuclear chemistry. GENERAL EXPECTATIONS You will be required to have read the sections as outlined in the syllabus, PRIOR to their discussion(s) during instructional time. Instructional time will be devoted to analyzing problems and concepts from material learned during prior classes, as well as during independent student reading. Independently, you must be able to successfully complete basic introductory problems, covered in high school Chemistry, so that class time is devoted to understanding laboratory concepts, as well as to mastering material (with collegiate-level proficiency). INSTRUCTIONAL MATERIALS and SUPPLIES REQUIRED BY STUDENTS 1- Textbook- Chemistry, Chang ed. 9. ISBN-13: 978-0-07-330170-9 2- Calculator: scientific or graphing. Basic calculators are not acceptable.

Chemistry. 8th ed. Boston, MA: Houghton Mifflin, 2003. -Brown, LeMay, Bursten. Chemistry The Central Science, 12th ed. Prentice-Hall, 2011. -Kotz, Treichel, Townsend. Chemistry & Chemical Reactivity, 8th ed. Brooks/Cole Cengage Learning, 2012. **You will be required to invest in at least one of the AP Chemistry course preparation books, currently on the market. There are several available. You should examine the titles and select one based upon personal preference. You are required to already have purchased the book(s). ASSESSMENT Summative and Formative: The chapter, and final semester exams simulate the AP exam in that they will consist of a combination of multiple choice and free-response questions. All tests are designed to ascertain degrees of your mastery of curricular content, covered throughout the course of the school year. Quizzes will also follow the AP exam format, and content- wise, will evaluate your knowledge from; information covered during lecture that day, laboratory experiments, investigative research, and from the Chemistry in Action and Chemical Mystery sections in the textbook. Homework is assigned and reviewed regularly. Due to time constraints, it is very likely that not all homework problems will be answered or worked out during class. You will receive however, the correct answers to all homework problem-sets submitted. GRADING You will be assigned grades based on the following criteria: Summative Assessment: 60% Chapter Exams* 15% Final Semester Exam Formative Assessment: 15% Laboratory Experiments (procedures/reports/facilitating)* 10% Classwork and Homework (daily participation/quizzes/research and instrumentation/ review sets/review sessions) *1-lowest test AND 1- lowest lab score will be dropped per semester. It must be noted that this does NOT include semester exams and/or zeroes obtained on any test or lab. Extra credit opportunities will be allowed throughout the course of both semesters. The points obtained will be assigned to the Classwork and Homework category, listed above. It MUST BE NOTED that extra credit will NOT be offered to you if you did NOT turn in one or more assignments, in either semester. Grade letters will be assigned on the following scale: A 92-100% A- 89-91% B+87-88% B 82-86% B- 80-81% C+ 77-79% C 72-76% C- 70-71% D+ 64-69% D 60-63% D- 55-59% F <55% Note: 1) Because the letter grades are assigned from a percentage that deviates from the normally accepted standards, there will be no rounding up of any percentage. In other words, a 88.9% will be a B+, and not rounded to 89% (A-). 2) At any point during the year, should your grade reach a 75%, you will have 2 weeks to raise it above that percentage. If the grade does not rise above that mark, or dips even further, parental notification will be made. If the grade still does not come up, within an appropriate time frame, a student-lead teacher parent conference will take place. LABORATORY EXPERIMENTATION The laboratory portion of the course includes challenging and relevant experiments. They are designed to reinforce topics covered during lecture, and will allow you to obtain a deeper understanding of chemical theories and principals, which will lead to concept mastery. Each experiment has been chosen to engage you in practical hands-on skills needed for; making observations of chemical reactions, designing experiments, following safe practices, recording data, calculating and interpreting data, predicting and reaching conclusions, and communicating experimental results. Through lab experimentation and investigative research, you will learn both the technical and functional operations of instrumentation used in Chemistry laboratories. Experiments: It is anticipated that 26 laboratory experiments will be performed. You will receive a zero for any lab you do not perform, due to an absence, or any other nonschool related reason. School related reasons must be approved by Mr. Linares. You will not be afforded the opportunity to make up any lab you miss. Opportunities will be afforded to obtain extra credit in place of points lost for labs not performed. Each student will be assigned two labs for “facilitation” purposes. Students will work in pairs to; 1- Meet with the instructor prior to the lab to go over the procedures as well as required materials and expected outcomes for their assigned lab. 2- Set-up the lab, including mixing all required chemicals. 3- Conduct pre-lab discussions with the class. 4- Perform the lab, as all other students are required to. 5- Tear down the lab, ensuring that all materials and instruments are returned to their assigned locations. 6- Conduct post-lab discussions with the class.

Predicting the Products of Chemical Reactions 100 and Writing Chemical Equations Composition Notebook for Experiments: In preparation for lab, and prior to the lab date, you are expected to have successfully completed the pre-lab exercises, in your composition notebook. This will include having the title, purpose, procedure, and raw data tables ready for the collection of data. The pre-lab questions must have been completed as well. If you do not complete the pre-lab requirement, you will NOT be allowed to perform the actual lab or, if allowed to perform the lab, a substantial amount of points will be deducted from the maximum points afforded for that particular lab. After collecting all pertinent data, you are expected to complete the lab (outside of class time) and include any graphs, calculations, post lab questions, error analysis, discussion and conclusion. Lab notebooks are expected to become a portfolio of lab work. NEATNESS/ORGANIZATION/FOMATTING COUNTS!!!! Formatting** a- Blue or black ink only (never pencil). Remain consistent on which color, in other words, once you use black-stick to it… b- Cross out mistakes with a single line (no white out or “scribble out”). c- Never remove pages. d- On the first page, write your name and student ID, the course, and the date. e- Leave the next three pages blank, for a table of contents to be inserted/filled in, as each lab is performed. For each lab: Note pre-lab, procedure, data, and analysis. Each page should be numbered consistently in your notebook, at the bottom/middle. Pre Lab (will be checked before you are allowed to proceed with each experiment) 1. Title 2. Introduction ( purpose) Opening paragraph of the Introduction: State the scientific concept (principle, theory, law) or laboratory procedure. Write in sentence form the objectives for this lab—include action verbs that were used to instruct you on what to procedurally; “measure”, “analyze”, “observe”, “test” something, etc. Second paragraph: Describe the purpose of the lab, in how the achievement of the first-paragraph-objectives, are designed to help you learn about the scientific concept or procedure of the lab. Include a safety section. The main focus is to know about the chemicals you are using. You should have a list of the chemicals and their safety information, if not, you may look them up on the internet. 3. Pre-lab questions Pre-Lab prepares you to get the most out of your lab. It consists of a series of questions which you are required to answer, before you perform the experiment. The pre-lab questions, appear in your lab manual. 4. Methods (procedure) Using your lab manual, handouts, and notes: Describe in bulleted form or flow chart how you will do the lab. *The Methods should only describe what you WILL DO in the lab and NOT what you FOUND. The point is to demonstrate that you have a solid grasp of the lab procedures. You should also include a labeled drawing of the set-up for the experiment. Provide enough detail of the materials you used and the methods you followed so that someone else could repeat the procedure. Make sure to note any differences between the procedures presented in the lab manual, and what you actually did (I suggest noting these changes in a different color ink – blue or black). This will be very important when you are writing the discussion portion of your report. Laboratory 5. Raw Data Table (to collect data obtained from procedures) This is the only section in your lab notebook, that you will be allowed to work on during class, all other sections, must be completed, outside of class time. Follow the procedures carefully; collect your data and complete the data table. Never forget to include units and watch the estimated digits (significant figures). Everything else must be done outside of class. Post-Lab 6. Post-lab results Create appropriate tables, graphs, and other figures to enable you to visualize your lab data. Doing so will allow you to identify trends, relationships, and other patterns in your data more easily. Calculations: show your work on all calculations necessary to complete the results data table. Include ONLY calculations from post-lab analysis, NOT from any pre-lab questions. 7. Post-lab questions If questions involve calculations, be sure to clearly label and show all necessary calculations. Discussion: Interpreting the results of the lab Step 1: For the opening paragraph of the Discussion, explain what the findings mean in terms of the scientific concept or laboratory procedure of the lab. In other words, discuss the connection between the evidence you collected and what you were supposed to be learning about by doing the lab. If necessary, refer to; graphs, drawings, tables, lists, or other visuals from the “results” section, to support your explanation. Step 2: In the final part of your Discussion, write about other pertinent items such as; a- the sources of uncertainty** in your lab methods that may have led you to unclear or unexpected answers. b- how your findings compare to the findings of other students in the lab. Provide an explanation for any differences. c- suggestions for improving the lab (what you do differently next time). **sources of uncertainty In science, a source of uncertainty is anything that occurs in the laboratory that could lead to uncertainty in your results. Sources of uncertainty can occur at any point in the lab, from setting up the lab to analyzing data, and they can vary from lab to lab. This is why it is so important to keep detailed notes of everything you do in the lab procedure and any problems you encounter. Try to be especially aware of any problems in setting up the lab, calibrating instruments, and taking measurements as well as problems with the materials you are using. Sources of uncertainty can be classified as: random--those that cannot be predicted. systematic--those that are related to personal uncertainty, procedural uncertainty, or instrumental uncertainty. When you cite uncertainty be sure to explain in detail EXACTLY how it impacted your results. If you follow the error through the calculations. Bottom line is that procedural and random uncertainty in general, is what will be looked for. It is understood that instrumentation and personal uncertainty are part of the process. You will be evaluated on your understanding of the chemical process, through your analysis of random and procedural uncertainties. ***FINAL NOTE*** Deviations from the required formula, as listed above for formatting, will result in poor grades.
