Wooster High School Course Syllabus 2015-­‐16 Subject: International Baccalaureate (I.B.) Chemistry Standard Level (S.L.) Teacher: Ms. Thompson Room: B-­‐9 Website: www.chemisthompson.com The Class Overview The curriculum for this course includes stoichiometry, atomic structure, periodicity, bonding, energetics, kinetics, acids and bases, equilibrium, oxidation and reduction, organic chemistry, measurement and data processing. There will be two additional topic options, which will include more advanced chemistry content. We will be using regular laboratory exercises to discover, explore and reinforce the aforementioned content. In addition to following traditional lab procedures, you will eventually devise your own procedures and design your own experiments. The overall goal of this course is to not only prepare you for the IB Chemistry SL exam, but to have you develop a thorough background in chemistry that can be applied to many aspects of your personal life and also as a preparation for college level science. Math Ability Advanced algebra skills are essential for this course, as a large amount of time will be used processing and analyzing raw lab data. If you have not successfully completed Algebra II or IB Math Studies, I strongly encourage you to reconsider your course selection. Grades: Academics grades will be based on the following: • Assignments: 20% • Labs: 20% • Exams and Quizzes: 40% • Final Exam: 20% Citizenship grades are based on the following: • Compliance with class rules. • Attitude and behavior. • Academic Integrity. Grade Scale: • A: 100%-­‐90% • B: 89%-­‐80% • C: 79%-­‐70% • D: 69%-­‐60% • F: 59%-­‐0% Student Requirements: Students are required to give their best effort and work diligently toward understanding the subject matter. This course is rigorous and requires students to be self-­‐motivated, hard-­‐working independent learners. This requires support from both parent and teacher. After-­‐school tutoring is available in the Career Center and I’m available after school to assist students (must make appt). Course Goal: Provide an instructional environment, educational opportunities, and lab experiences that focus on student learning about chemistry, and ultimately, prepare students to take the IB exams and earn their best grade possible. Course Objectives: Present lessons and educational strategies with primary consideration given to the International Baccalaureate Chemistry Topics 1-­‐11 and options A: Materials and C: Energy. IB Exam Dates: May 12 & 13, 2016 Class Expectations: * On-­‐Time, Prepared, Hard Work, and Positive Attitude! * No Excuses! * No late work accepted! * Papers without name, date, class, and period receive a zero! Academic Integrity Policy Colt Learner Profile: Principled inquirers who communicate with integrity. Plagiarism is a serious offense that should not be taken lightly. Plagiarism, “the submission for assessment of the unacknowledged work, thoughts, or ideas of another person as your own.” Students are expected to acknowledge fully and in detail the work, thoughts, or ideas of another person, if incorporated in their own work. Students must be certain that their own work is never given to another student, either in the form of hard copy or by electronic means, knowing that it might be submitted for assessment as the work of that other student. Students who are caught cheating on exam, homework or class assignments. Failure to maintain academic integrity will result in a zero on the assignment and an “F” in citizenship! Course Information: 2015 – 2016 Disclaimer in ALL AP & IB Syllabi The following WCSD policy will be applied to all students registered in an IB or AP course. ALL requirements must be met before the AP or IB designation is awarded and recorded on your transcript. • Students registered in an IB course, regardless of whether they are an IB Diploma Candidate, IB Anticipated Candidate, or an IB Courses student, must submit all materials required to be submitted to IB in order to earn the IB designation on his or her transcript. • Students register for AP or IB courses during regular high school pre-­‐registration each fall. •

All WCSD students enrolled in an IB or AP course are required to take the exam in that course per Administrative Regulation 6501; therefore, students registered in AP and IB classes will be automatically registered for the course exam unless direct communication has been made to the IBDP and AP Coordinator. AP students that do not show up to their exam will be charged a $20 processing fee. Students must be registered for ALL IB exams before the first IB deadline of NOVEMBER 14. Students making changes to their IB registration (dropping a class, changing courses, adding courses, or changing EE subjects) after this deadline will pay an IB amendment fee. Prices increase further after November 15, January 15 and April 15. Students dropping an IB course after the November 14 deadline will not receive a refund for their IB registration fee. Students wishing to maintain the IB designation on their transcripts, and obtain the IB weighting of the course must complete all components required by IB (including all IA’s, exams, orals, presentations, labs, etc.). Students in your course are encouraged to take the AP chemistry exam. IB Chemistry Exam Dates o Paper 1 & 2 -­‐ May 12, 2016 o Paper 3 -­‐ May 13, 2016 AP Chemistry Exam Dates o Monday May 2, 2016 IB exam fees Due November 2, 2015 o Diploma Program students will pay a $164 registration fee their junior year and $113 per IB exam (no registration fee is due their senior year as long as they remain a diploma program student). o IB Courses/Certificate students will pay $164 registration fee each year, and $113 per exam. AP exam fee -­‐ $ 92 are due February 1, 2016 Late fees will be assessed at $5 per 30 days late. REDUCED FEES: If students qualify, we highly suggest that students apply for the Free and Reduced Lunch (FRL) Program, for this will reduce exam fees tremendously. Students qualifying for FRL pay $15 per IB exam (this amount changes yearly according to the State of Nevada) and $20 per AP exam. IB registration fees are not reduced. o Go to the district web page for more information and a link to the site § http://www.washoe.k12.nv.us/parents/nutrition-­‐services/nslp o Direct Access: § https://rocket.washoeschools.net/ o DEADLINE for applying for FRL for the 2015-­‐2016 school year (for testing fee reductions only) is February 1, 2016.

In 1921 Thomas Midgley discovered that the addition of a lead compound could improve the combustion of hydrocarbons in automobile (car) engines. This was the beginning of the use of leaded gasoline (petrol). The percentage composition, by mass, of the lead compound used by Midgley is shown below. a) (i) Determine the empirical formula of the lead compound.
