These topics are covered in Chapters 1-12 in your book. After completing this course, you should have a strong foundation for upperlevel courses in the Chemistry Department. We hope also that as part of this learning community that you will understand better the connections between the study of chemistry and how it relates to other scientific areas. Overall Learning Objectives: Know the definition of chemistry and the scientific method Express common mathematical techniques in the solving of chemistry problems Understand the role of the atom in chemistry Distinguish, classify, and explain the properties of compounds

2 Recognize and explain the fundamental nature of chemical reactivity Differentiate and describe the principles of the phases of matter General Education Learning Outcomes: Students will be able to apply physical/natural principles to analyze and solve problems. Students will develop an understanding of the impact that science has on society. General Education Learning Outcomes are assessed in the second semester of the two course sequence. Co-requiste: Chemistry 111 Lab, which is a separate one-hour course. Texts: 1) Required: Burdge and Overby, Chemistry: Atoms First (McGraw-Hill) 2nd edition. For online registration of the Connect Database use the following: Chemistry 112, the next course in the Chemistry sequence, will cover the remaining chapters in the book. Do not sell your text at the end of the semester if you are continuing on to Chem ) Learn Smart Prep, this module which must be purchased separately from the textbook (see instructions on the web and in the ) counts for 5% of your final grade and must be completed by 1/20/15 and is a requirement for the course. Calculator: You will need a calculator for exams. You will need to bring this calculator to class. Course Expectations: A. Attendance Class attendance is to your benefit. With extremely small exception, performance in the course is directly proportional to attendance. Students are responsible for all information presented in class whether they are present or not. Students should obtain notes from a classmate, read the associated material in the text, and then come ask me questions

3 Please note that an Absence Memorandum from the Office of Undergraduate Studies only verifies your documentation for missing a class. It does not entitle you to make up or be excused from any work, assignment or test. B. Responsibilities You are accountable for all material covered or assigned in class. You are expected to spend a minimum of 3 hours of study for every hour spent in lecture. The instructor is here to explain the material and help you to the best of his time and ability. However, the burden of learning is upon you, the student. C. Academic Integrity One of the core values of the College is academic integrity. This course is conducted under the Honor Code ( of the College of Charleston. Students at the College are bound by honor and by their acceptance of admission to the College to abide by the Code and to report violations. Faculty members are required to report violations of the Honor Code or Code of Conduct to the Office of Student Affairs. Conviction of an Honor Code violation in this class will result in the grade of "F" for the course. Please consult the department's Policy on Scientific Integrity ( D. is considered an official method for communication at the College of Charleston. College of Charleston accounts are automatically assigned to all students upon acceptance at the College. If a student wishes to have redirected from their official College issued account to another @yahoo.com, or any other server other than the they may do so, but at their own risk. Having redirected does not absolve the student from the responsibilities associated with official communication sent to his or her College account. The College is not responsible for the handling of by outside venders or unofficial servers. A link to instructions on how to forward Edisto can be found by clicking on Web Mail from the CofC home page. Students are expected to check their College of Charleston official on a frequent and consistent basis in order to remain informed of College related communications. Checking on a daily basis is recommended. Students have the responsibility to recognize that certain

4 communications may be time-critical. I didn t check my , error in forwarding , or returned to the College with Mailbox Full or User Unknown are not acceptable excuses for missing official College communications via . E. Course Materials: Some course materials will be available to students on OAKS. You will need to take careful lecture notes and additional homework packets will be assigned prior to class on an as needed basis and you should bring them to the assigned class. The best use of our time together is when you are following the lecture and working problems with me. F. Homework: The key to success in this class is doing chemistry problems again and again. If you are not working out problems every single day, you will not do well in this class. You will be expected to work through problem sets assigned as well as the end-of-chapter questions. These will not be graded or collected but they will serve the basis of both the quizzes and tests. Nonetheless, they are the key to your success. It is your responsibility to learn how to work the problems! G. Hourly Exams The following are tentative dates for the exams. These dates are subject to change. Tuesday, February 3 Tuesday, February 24 Tuesday, March 31 Tuesday, April 21 Final Exam: To Be Scheduled. Your final is a standardized exam written by the American Chemical Society. It is a TIMED, multiple choice test. You will have 110 minutes to complete the 70 multiple-choice questions. Makeups: There are NO makeup tests. An unexcused absence on the day of an exam will result in a zero on that exam. If you have an excused absence documented by the Dean of Undergraduate Studies that I find plausible, your remaining test scores will all be weighted equally and more heavily towards the final course grade to compensate for the missed exam. If you are going to miss an exam, notify me ahead of time by phone message or by . Even if you have a good excuse, you may not miss more than one exam. You will be dropped from the roll for excessive absences if you miss more than one exam.

5 Supplemental Instruction and Tutoring: This learning community will have an SI for the course that is responsible for provide additional instruction of the chemistry content. Our SI is to be determined. The SI will be arranging a variety of times when he/she will be available to work through problems with you. Your attendance is not required, but data has shown that students who attend regularly do better in the course. Also, tutoring at the Center for Student Learning in chemistry is available to students at no cost. The hours of the walk-in science tutoring room are available online ( Deportment and Quizzes Grade: To maintain a classroom environment that is conducive to learning, I expect certain behavior from students in my classes. Students that text, chatter, giggle, sleep, whisper, whine, arrive late, leave early, or come unprepared are disrupting their fellow students learning experience. Deportment and quizzes during the semester will comprise 15% of your grade. There will be a total of 8 quizzes during the semester and they will comprise 15% of your grade. Quizzes will occur the class after we finish a chapter and will contain 4 questions which will come directly from the homework for the chapter. Since hourly tests occur at the end of the 3 chapter block, there will not be a quiz on the third chapter of a block. Grading: Your final grade will be calculated by the following formula: 4 Exams: 15% each Final Exam, ACS Standard Exam 20% Quizzes and Deportment: 15% in Total LearnSmartPrep 5% Letter % GP A A B B B C C C D D D F Below 60 0
