Syllabus AP Chemistry 2014-2015 Because of the nature of this course and the amount of new material that will be covered, a strong preparatory background in Pre-AP Chemistry is a requirement. If you had me for Pre-AP Chemistry you already have a strong background. The topics that I expect that you already know include: atomic structure electron configurations bonding VSEPR theory acid-base chemistry nuclear chemistry chemical names and formulas chemical reactions (balancing and completing) periodicity behavior of gases mole concept mole calculations stoichiometry making and interpretation of graphs making observations from laboratory situations The nature of Chemistry requires the student to know certain basic facts that MUST be committed to memory. Mathematics is an integral part of this class. Problem solving strategies will be stressed throughout the year and this course requires the student be able to solve problems WITH and WITHOUT a calculator. TEXTBOOK: Chemistry, Zumdahl and Zumdahl., (publisher Cengage Learning) 9th Edition –©2013 STRUCTURE OF THE COURSE: AP Chemistry is built around six big ideas and seven science practices. The big ideas are: Big Idea 1: The chemical elements are fundamental building materials of matter, and all matter can be understood in terms of arrangements of atoms. These atoms retain their identity in chemical reactions. Big Idea 2: Chemical and physical properties of materials can be explained by the structure and the arrangement of atoms, ions, or molecules and the forces between them. Big Idea 3: Changes in matter involve the rearrangement and/or reorganization of atoms and/or the transfer of electrons. Big Idea 4: Rates of chemical reactions are determined by details of the molecular collisions. Big Idea 5: The laws of thermodynamics describe the essential role of energy and explain and predict the direction of changes in matter. Big Idea 6: Any bond or intermolecular attraction that can be formed can be broken. These two processes are in a dynamic competition, sensitive to initial conditions and external perturbations. Some of the big ideas will seem very familiar to you. The majority of big idea one, two and three were covered in Pre-AP Chemistry. However, big idea four, five and six were not covered in any great depth in Pre-AP Chemistry and will be new to you. Most of the time in this course will be spent working on the last three big ideas. The science practices for AP Chemistry are the same for all AP science classes. The science practices are designed to get the students to think and act like scientists. As you read through this list, the concepts and practices that are listed below will seem second nature to you, since they were embedded in the laboratory investigations, problems and projects from Pre-AP Chemistry. The science practices are: Science Practice 1: The student can use representations and models to communicate scientific phenomena and solve scientific problems. Science Practice 2: The student can use mathematics appropriately. Science Practice 3: The student can engage in scientific questioning to extend thinking or to guide investigations within the context of the AP course. Science Practice 4: The student can plan and implement data collection strategies in relation to a particular scientific question Science Practice 5: The student can perform data analysis and evaluation of evidence. Science Practice 6: The student can work with scientific explanations and theories. Science Practice 7: The student is able to connect and relate knowledge across various scales, concepts, and representations in and across domains. LABORATORY INVESTIGATIONS The laboratory portion of this class is to be the equivalent of a college laboratory experience. Because some colleges require proof of the laboratory portion of the course before granting credit, all students will keep a laboratory notebook, provided by the teacher. Some of the laboratory investigations will require the students to spend time in tutorials after school. At a minimum, twenty-five percent of instructional time will be spent in the laboratory. The laboratory manual that is given to the students is designed to be a complete laboratory experience for the student. It is designed to be “combed bound” and the students write their laboratory reports in the notebook. When the students finish AP Chemistry, they are encouraged to take their laboratory notebook with them to college. The laboratory notebook is 264 pages long. It includes nineteen laboratory investigations. They are all “wet labs” with one being micro-scale. Seven of the labs are student inquiry based. The school is on a block schedule, so class length is approximately 90 minutes, which generally allows enough time for students to complete the laboratory investigation. Students know that additional time on the weekend might be required to perform labs. The laboratory manual has sections on purpose, procedure, equipment needed, data, analysis, questions for the students to answer and conclusion. Students must turn in completed laboratory write-ups for each lab. Each student will be required to report their results once per semester using a method of their choice (PowerPoint, Poster, Article, etc.) Materials Needed: The following are the materials needed for this class. 1. 2. 3. 4. Scientific Calculator (a graphing calculator is fine!) Black or blue pens and #2 pencils with erasers. Willingness to ask questions and participate in class. Alert and active human brain. GRADING: A typical nine weeks grading period would have: Tests 80%, Tests: Tests will consist of two parts: Part one multiple choice without calculator and Part 2 free response which can be with or without calculator. Labs, quizzes, independent study packets 20% Within a grading period there will be generally no more than three major tests. There will be daily short quizzes. Quizzes will be averaged per week and recorded as one grade. All of the tests will be in AP format and will be graded according to AP standards. The grading procedures for this format will be explained before the students take the exam. Course Expectations: 1. ALL students are expected to actively take notes during teacher presentation. Although a textbook will be given to students, some material will not be found in the book. It is important to pay attention in class and ask questions when you do not understand. The lecture notes are NOT A SUBSTITUTE FOR YOUR NOTES. They are an aid to help you, not the be all and end all. 2. NO WORK-NO CREDIT- NO KIDDING!!! 3. All tests are closed book and notes. As Chemistry is a course that builds upon itself, tests are cumulative. The only notes are your “AP sheets”. 4. Students are expected to take notes, be attentive, and contribute to the class. Students that honestly try and cooperate will always be given consideration when borderline grades occur. 5. Labs are very serious and each student is expected to follow the PISD Laboratory Safety policies. Failure to do so will result in the removal of the student from the lab area and alternative written work will be assigned for the remained of the semester for each laboratory investigation. 6. Calculator use is a privilege, not a right. Using a calculator to cheat or damaging a calculator will result in loss of the calculator privilege. 7. Students scoring below “70” on a Major Grade shall be allowed to redo the assignment/test. To qualify, the student must attend 2 tutorial sessions, turn in any missing assignments, and will be required to take the make-up outside of normal class time. The higher grade, with a maximum of “70”, shall be recorded. Retesting/redoing should be completed within five school days of the original assignment. 8. Students will not be allowed in class if they are not in the door when the tardy bell rings. 9. It is the student’s responsibility to obtain make-up work. One extra day is given for make-up work for each day absent. If absent on an A day pick up makeup work on the following B day. If absent on a B day pick up makeup work on the following A day. 10. If students are absent the day before a scheduled test, they are expected to take the test the same day they return. In the case of sports or planned absences, work should be completed before leaving when possible.

I am usually here every day before and after school Except Wednesday Mornings Points to Ponder: WHY ARE YOU IN THIS CLASS????? o o o o Are you here to get college credit? Are you here to see the material before you get to college and take the class again? Are you here to get the T-shirt? What are your priorities? Please do not be afraid to make mistakes! If you were not supposed to make mistake, the erasers would not be on the pencils! I get paid to answer your questions…PLEASE make me earn my pay. This is a college course and as such, IT IS HARD. You will be expected to do a great deal of higher level thinking, and yes it will hurt your head sometimes. Please look at this course as a bridge between high school and college. You get college work and material…with all of the safety nets of high school. Do you have a STUDY GROUP? It is good to work UT homework together. The UT homework counts as extra credit because I expect you to have worked together. However, if you just copy someone else’s UT homework, you may get a good grade, but you will fail the quizzes and/or tests and the extra credit will do you no good. To get a FIVE on the AP Chemistry exam you need 63% correct on the test! To get a THREE on the AP Chemistry exam about 45% correct on the test! Unlike me, you have a life outside of school. If you have something going on that will interfere with your ability to turn in work to me…let me know, we will try to work something out. My expectation is that ALL of you to take the AP Chemistry EXAM at the end of the year. If it wasn’t for people like me, your parents would never know you are normal.
