AP Chemistry Mrs. Hopkins Rm A200 Conference Period: 9:15am-10:11am Tutorials: Wed. 3:10-4:10pm Room A200 schopkins@alvinisd.net Course Description Welcome to our AP Chemistry Class! I hope you will find this class rewarding, interesting, and fun. Please familiarize yourself with the class layout and expectations so you may have a successful experience in this class. Chemistry is the study of the world around you. In AP Chemistry, We will be studying matter, energy, atoms, chemical reactions, solutions, and more. In addition, we will spend time in the laboratory with emphasis on safety, scientific processes and developing critical thinking skills. Everything in the AP Chemistry class is geared to prepare the student for success on the AP Chemistry exam and for University level Chemistry. *Please note that there is a great deal of math involved. You will need a binder with dividers and writing utensils every day. Please come prepared. Be prepared to turn in assignments at the end of class each day. Grading Policy** **Please refer to the district AP/PAP contract for all Grading and Homework policies Grade Categories 40% - Major Exams/Major Projects 40 % - Labs/Lab Writeups 20 % - Daily Work/Class Work/Quizzes Cheating will never be tolerated on ANY assignment. Your parents will be contacted, both parties involved in cheating will receive a zero and the grade will not be allowed to be made up. If you need help on an assignment, ask for help. It is the job of the teacher to make sure that all students understand the lesson. SPEAK UP if you need help!!! Homework Any and all homework given will be meaningful to the work done in class. All students will be required to do their homework in Google Classroom. Their access will be set up on day 1. It will also be required that all students have access to remind.com either through a computer or on their phone via the remind app. **Late work will be per District Grading Policy. Textbooks will not be passed out by the teacher, but it is HIGHLY RECOMMENDED if you do NOT have access to a computer or device that you check out a book from the textbook office. There will be a classroom set of books to use during class, but these books may not leave the classroom! The textbook is an excellent resource for students that may struggle or need extra reinforcement. Instructions will also be passed out that will allow you to access the textbook online. Tests Regular formative assessments will be given to check for student understanding. I anticipate that the assessments will be at least weekly, if not 2-3 times per week. These formative
assessments will allow me to more accurately determine where the student is academically in my class. These smaller assessments will lead up to Unit, Semester, and Final exams; Exams will be at least every unit. Each unit will therefore have a minimum of 2 exam grades each: the multiple choice exam and the free response exam (FRQ). Make-Up Policy If you are absent, I have an area at the front of the room (organized by period) that has work from the week that you may pick up. This is YOUR responsibility. It is also your responsibility to turn the make-up work in to me by the deadline in accordance with the student handbook. Cell Phone/Device Policy There are no cell phones/devices allowed in class. They are a distraction and student grades go down because of them. During class time, you may connect your phone to your own charger and charge your phone/device if you would like to charge your phone. Please understand that if I see you on your phone, I will take the phone up immediately. We do not have much time to cover the amount of material in class that we need to cover. Classroom Discipline Students are to adhere to the Social Contract that we will develop on Days 1 and 2. Any deviation from the contract will result in: Warning #1: Name written on the board Warning #2: Mark after the name on the board Warning #3: Mark after the name and a Teacher Detention/Call home (30 min detention on a scheduled date) Warning #4: Another mark after the name and Office referral/call home SCOPE OF THE AP CHEMISTRY CLASS I.

Descriptive Chemistry (10 15%) Knowledge of specific facts of chemistry is essential for an understanding of principles and concepts. These descriptive facts, including the chemistry involved in environmental and societal issues, should not be isolated from the principles being studied but should be taught throughout the course to illustrate and illuminate the principles. The following areas should be covered: 1. Chemical reactivity and products of chemical reactions 2. Relationships in the periodic table: horizontal, vertical, and diagonal with examples from alkali metals, alkaline earth metals, halogens, and the first series of transition elements 3. Introduction to organic chemistry: hydrocarbons and functional groups (structure, nomenclature, chemical properties) V. Laboratory (5 10%) The differences between college chemistry and the usual secondary school chemistry course are especially evident in the laboratory work. The AP Chemistry Exam includes some questions based on experiences and skills students acquire in the laboratory: making observations of chemical reactions and substances recording data calculating and interpreting results based on the quantitative data obtained communicating effectively the results of experimental work Colleges have reported that some AP students, while doing well on the exam, have been at a serious disadvantage because of inadequate laboratory experience. Meaningful laboratory work is important in fulfilling the requirements of a collegelevel course of a laboratory scienceand in preparing a student for sophomore-level chemistry courses in college. Because chemistry professors at some institutions ask to see a record of the laboratory work done by an AP student before making a decision about granting credit, placement, or both, in the chemistry program, students should keep a laboratory notebook that includes reports of their laboratory work in such a fashion that the reports can be readily reviewed.
