WELCOME

AP chemistry II is a second year course designed to provide students with a solid first-year college chemistry experience, both conceptually and in the laboratory. At the end of this course, students should be able to earn college credit by examination and enter college well prepared.

Due to the nature of this course and the amount of new material that are covered, a strong preparatory background in Chemistry I is a requirement. Students must be proficient with the following concepts:

 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 interpreting graphs  making observations from

laboratory situations

Chemical literacy requires the student to know certain basic facts that MUST be committed to memory. Mathematics is an integral part of this class. The course will incorporate problem-solving strategies throughout the year. The student must be able to solve problems WITH and WITHOUT a calculator.

TEXTBOOK:

Chemistry, A Molecular Approach, Nivaldo J. Tro (publisher Pearson) 3rd Edition – AP Edition © 2014

STRUCTURE OF THE COURSE:

AP Chemistry revolves 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.

(2)

The bulk of the content from big ideas one, two and three were covered in Chemistry I; however, Chemistry I did not cover big ideas four, five and six in great depth, if at all. In an effort to deepen the understanding of chemistry, as the course focuses on the new concepts the prior concepts will be incorporated and review.

The science practices for AP Chemistry are the same for all AP science classes. The science practices are a continuation of the skills fostered in Chemistry I and are designed to get the students to think and act like scientists. 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. All students will keep a bound laboratory notebook as part of this college laboratory experience. Every student will write up complete lab reports for each laboratory experience including an introduction, purpose, safety, procedure, results, error analysis (SP 5), questions (SP 3), and conclusion (SP 6). Students will also include raw data and observations (SP 4), drawings (SP 1), calculations (SP 2), and graphs (SP 5) if appropriate. Some of the laboratory investigations may require the students to spend time in tutorials before school. Students will spend at a minimum twenty-five percent of their time in laboratory investigations.

The school is on a traditional seven period schedule, so class length is approximately 50 minutes, which generally allows enough time for students to complete the laboratory investigation in one or two class days. To make the most of the 50 minutes, students are required to come in on lab days prepared and ready to work. After each laboratory investigation, students are required to answer a series of questions based on “what if…” The main purpose of these questions is to help the students analyze and think critically about what will happen to their results based on specific errors that could occur. Error analysis is a large portion of each lab when applicable. At the end of each lab, students verbally process the important concepts of that lab through class discussion. The students will participate in seventeen “wet-lab” laboratory investigations and three computer and/or calculator simulations. Seven of the twenty laboratory investigations will be inquiry based.

Laboratory Equipment

The school is equipped with a full range of glassware (beakers, flasks, burets, graduated cylinders, pipets, etc.), instruments (Spec-20s, analytical balances, centrifuges, ovens, etc.), and data gathering probes. All raw data will be recorded in the students’ laboratory notebooks. All students have access to computers with a full range of MS Office products and TI-83+ calculators to help students analyze laboratory data. Students will be required to enter their results in spreadsheets to verify their calculations when applicable. A PowerPoint of common lab equipment is available online.
