AP Chemistry Syllabus Course Description The Advanced Placement (AP) Chemistry program is designed to prepare students for the AP Chemistry exam and for their first year of college chemistry. In some cases, passing the AP Chemistry test will allow students to take a second year chemistry course their first year of college. This course will cover material equivalent to one full year of chemistry at a college or university and to cover all the material, it will move fast. The rigorous course will challenge you as a student and is intended for students who have demonstrated a willingness to commit considerable time to studies and assignments outside of class. The goal of this course is to develop the student s ability to incorporate mathematical skills to the solution of chemistry problems from examples, textbooks and laboratory activities. This course prepares students for the AP Chemistry exam and it is strongly recommended that students purchase an AP Chemistry Study guide and, instead of waiting 2 weeks before the test, begin studying now. As mentioned above, passing the AP Chemistry exam can earn you college credit so this class should not be viewed as college prep but a college class with expectations for college level effort, participation and work. During the duration of this course, you will be assessed in a number of ways including quizzes, tests, homework assignments, labs and a portfolio. The test and quiz portion of this course will be similar to that of any college level test covering material from assigned readings and discussed in class. Homework will be assigned at the beginning of a unit and will be due the date of the test, no late work accepted. As Chemistry is a lab intensive topic, there will be several labs performed during the course of the year. It is imperative that you read the lab procedures before the day of the lab and that you and your lab partner work together to complete the lab with good results in a timely manner. Your lab performance will be based on writing formal lab reports and building / maintaining a Lab Report Portfolio. Instructions and format on writing lab reports are attached Notebooks and Lab Report Portfolios should be kept current and in chronological order as they will be checked periodically and reflect in your grade. Again, the aim of this course is to act as a college level Chemistry course and prepare you for the accompanying AP Chemistry exam. Your dedication and efforts to this class will reflect in your grade as well as the score you earn if you choose to take the AP exam. Text Book and other resources * Chang, Raymond.

Lab Report Requirements The following is information that needs to be included in each lab report. All sections must be included in reports unless otherwise specified by instructor. Each student must write a lab report for each experiment performed. In the case where lab partners are involved, you are required to write separate and different reports, copied or plagiarized reports may result in earning no points and disciplinary action. Lab reports should be written in your own word avoiding the use of names, pronouns or other information relating to people performing the lab. Lab reports should be written as you would write and English report, correct grammar, punctuation and spelling are expected. The report should be neat and on full sheets of paper. The only abbreviations that you should use are standard scientific measurements (mm, ml, g, etc.). All statements and descriptions should be specific and clearly worded. Refer to particular parts of the experiment when describing observations and discussing results. The top of each report should include the name of the experiment, your name and the name of your lab partner (if applicable). The body of the report should be written using the following format. Label each part and separate it from the other parts of the report. 1. INTRODUCTION / PURPOSE Describe, in your own words, the purpose of the experiment. Include a brief description of the method used in the experiment. This section should be no more than a few sentences long. 2. MATERIALS This section should list the materials and quantities of each item used in the lab experiment. 3. PROCEEDURES You will be required to complete a detailed procedure of the lab in your own words before the day of the lab. This means you should read the lab procedures before the day of the lab and use the lab sheets as a guide. 4. DATA This section should include all experimental data recorded and any observations. Present all data in a form that will allow it to be readily understood by the reader. Numerical data should not be presented in sentences or paragraph form, but in clearly labeled and well-designed data tables. Attach correct units where appropriate. 5. DATA ANALYSIS / CALCULATIONS show the set-up used to perform each calculation. Units and significant figures should be carried through the calculations. If the same calculation must be performed multiple times, you only need to show the complete calculation once. The results of the calculations are sufficient for the remaining pieces of data. Graphs should be included with this section as well. They should have a brief title at the top describing the nature of the graph. Axes should be clearly labeled with appropriate scales, titles and units used. Graphs must be drawn on graph paper or printed using graphing programs. 6. DISCUSSION / ERROR ANAYLSIS Briefly summarize the results of the experiment. Discuss your results both qualitatively and quantitatively. While the form of the discussion may vary depending on the experiment, you should answer the following questions. a. What do the results of the experiment show or what conclusion can be drawn from the experiment? b. Do the results agree with theory or established values of experimental quantities? c. What errors, both actual and possible, are present in the experiment? d. How large is each of the errors in the experiment and what effect would the error have on the experimental results? e. If your results do not agree with theory or established values of experimental quantities, why do they disagree and are the errors in the experiment large enough to account for the disagreement? 7. QUESTIONS Some experiments will contain questions for you to answer. Questions that are included as part of the procedure should be answered in your discussion. Otherwise, answer questions in this section. Complete sentences should be used to answer questions 8. CONCLUSION Only a brief one or two sentence statement summarizing the experiment and the results obtained is required.
