CHEMISTRY 101 Spring 2012 Syllabus Lectures Meetings M and W 11:15 am 12:05pm 117 Osmond Laboratory Meetings Section 001 Friday 1:25 pm 4:25 pm 1 st floor Whitmore Course Instructor: Office: Email: Office Hours: Mary Shoemaker 201 Whitmore Lab mcs163@psu.edu 2-4 Wednesday and Friday, 110C Whitmore And by appointment Course Webpage: http://courses.chem.psu.edu/chem101 Undergrad Chem Office 210 Whitmore Lab, Lacey Rigg, 863-3261 General Remarks Chemistry 101 is a general introduction to chemistry course that incorporates both Lectures and Laboratory Experiments in developing an understanding of chemical concepts and practices. For some students, Chem 101 provides the chemistry required by their major area of study. For other students, Chem 101 provides review and preparation for subsequent General Chemistry classes such as Chemistry 110, Chem 111, and Chem 202. Chem 101 is mainly concerned with the basic skills and conventions for chemistry and is suitable for students who have not taken any previous chemistry. The experience of teachers of Chem 101 indicates your mathematical aptitude as the most important factor for success. The greatest stumbling block is the inability to go from a word problem through an algebraic expression to a solution. You should not take Chem 101 unless you have already taken, or are currently taking, a course in algebra through the concept of logarithms. The goals of the laboratory are to train you in safe, accurate, and standard laboratory procedures while giving you direct experience with the chemical phenomena and principles being taught in the lectures. You will learn how to use balances, the burner, and volumetric devices, and build the confidence you will need in future courses. Concepts learned in lecture will be put to the use in the laboratory. viii
I) COURSE OBJECTIVES When you successfully complete this course, you will be able to: Describe the structure and behavior of atoms Extract data and information from the periodic table of the elements Predict the properties and behavior of elements based on their position in the periodic table Understand the process of chemical bonding and predict what type of bonds will form between different substances Correctly name chemical substances based on the ratio of the elements in the compound and the type of bonding between the atoms Determine when chemical reactions will take place between substances, the ratio in which the substances will combine, what new products will be formed in the reaction, and the amount of product formed from a given amount of starting materials Identify the intramolecular forces that can exist between atoms within a chemical compound or molecule and the intermolecular forces that occur between molecules Describe and compare the properties of gases, liquids and solids II) ADMINISTRATIVE PLAN Your grade will be determined by a number of lab quizzes, lecture material, three examinations, laboratory grade, graded homework problems, in-lecture worksheets, and your final exam grade. The grades will be weighted as follows: Grading Three examinations Lab quizzes Graded homework Final exam 12% Laboratory 30 % 12 % each 12 %, will be given at the beginning of lab period 10 % these will be announced in lecture and posted on the web and turned in at the beginning of each lab class. ix
Final Grade Distribution: The exact point requirements for each letter grade will be decided at the end of the course. Based on past years, the grade distribution for this course will be close to: Grade Percentage A 91.5-100 A- 89.5-91.4 B+ 86.5-89.4 B 81.5-86.4 B- 79.5-81.4 C+ 74.5-79.4 C 67.5-74.4 D 56.5-67.4 F 0-56.4 There is no assurance that the grade distribution will be the same this semester. However, you may assume that it will not be greatly different. There is no predetermined grade distribution for this course; if, at the end of the course everyone has a final point grade in the A range, then everyone gets an A. x
Example: How the Grading System Works: If a student has the following scores: Exam 1= 55.0% Exam 2= 75.0% Exam 3= 80.0% Quiz average= 83.5% Homework average= 75.0% Final Exam= 75% Laboratory Grade= 90.0% Calculation of final course grade is as follows: (0.550)(12) + (0.750)(12) + (0.800)(12) + (0.835)(12) + (0.750)(10) + (0.750)(12) + (0.900)(30) = 78.72% 6.60 + 9.00 + 9.60 + 10.02 + 7.50 + 9.00 + 27.00 =78.72% According to the final grade distribution below, this would be a C+. Each student should keep track of her/his earned grades and use the above example to calculate the grade at different points throughout the semester. If you are having trouble with this calculation or want to double check your answer, see your instructor. xi
III) POLICIES 1) EXAMINATIONS There will be three examinations during the semester and a final examination during the final exam period. These examinations will follow a multiple-choice format and will be graded by University Testing Services. The dates for the examinations are fixed and given in the attached class schedule. The University will set the final examination time and place in its final exam schedule. Locations for exams will be announced in class and posted on the class web site. Please do not phone or e-mail for exam locations. Make-up examinations will be considered only in special cases if there is just cause. If you miss an examination for a non-trivial reason (documented illness or death of a close relative), notify your instructor as soon as possible. After review of the circumstances, you may be allowed to take one comprehensive make-up exam, during the thirteenth week of class. You should bring a nonprogrammable calculator, some #2 pencils, an eraser, and your student I.D. card to each examination. You may not use the calculator on your cell phone for exams. Borrowing calculators is not allowed during quizzes and examinations. A periodic table will be provided with exams as needed. Copies of exams from earlier years are placed on the class web site and practice on these exams is highly recommended. For missing grades, or wrong form results (A/B mix up), see Ms. Lacey Rigg in the chemistry undergraduate office (210 Whitmore Lab). 2) ASSIGNMENTS READINGS are assigned for each lecture (a tentative schedule is included). Some topics that you will be responsible for exams may not be deeply explored in lectures. It will be assumed that you are keeping up with the material. HOMEWORK will be turned in on a regular basis. Homework assignments are due at the start of lab. The homework assignments and due dates will be announced in lecture and posted on the website. These assignments are designed to help you keep up with your reading in the text and will aid in your understanding of the material. By doing these before coming to lecture you should be able to get more out of the lecture. Homework cannot be turned in at a later time. However, homework may be turned in early. xii
Homework must be turned in BEFORE THE CLASS PERIOD STARTS. There will be no exceptions. Homework should include your name, name of your TA, the assignment number and the date. If you have to use more than one page, staple the pages and label each page. Please do not use sheets from spiral notebooks unless you remove the ragged edges. In your answers you must show enough work to clearly demonstrate how you solved each problem. Many of the home work problems will be used as models for exam questions. 3) ATTENDANCE Lecture: Attendance to the lectures will not be monitored. However, there will be occasional problem sets worked out in small groups during lecture. Thus, you should attend every lecture. You are also responsible for all course material and administrative announcements made in class, including problem assignments, syllabus changes, and exam locations. Lab: In the event that you must miss a laboratory session with a valid excuse, you must submit a copy of the Excused Absence and Make-up Lab Request form to your instructor within one week of missing the lab. The Excused Absence and Make-up Lab Request form exists in the laboratory manual. Submission of a request does not guarantee approval. You will receive notification from the instructor as soon as possible regarding the status of your request. If your request is granted, you will be able to attend a make-up lab session near the end of the semester and turn in an alternate homework assignment. Failure to file a request, or unacceptable requests, will result in a grade of zero for the missed laboratory session and homework. The laboratory is an essential component of the course. Two or more unexcused laboratory absences may result in an "incomplete" grade for the course. xiii
4) COURSE RESOURCES a) Resource room: The Department operates a Resource Room, 211 Whitmore Lab, to provide free help to Chemistry students. The operation hours of the resource room will be announced in class. You are strongly encouraged to use this service as soon as you discover any need for help. b) E-mail: When sending an email to your instructor and/or to your TA you should do the following to get a response: Identify yourself and include Chem 101 in the subject line. Write concise messages and use proper language. If you have a concern about your grade, talk directly to the instructor. c) Lecture periods: The lectures are meant to explain the material to you and to your classmates. It is a time when you should concentrate, listen, and actively participate in class activities. Turn off your cell phones and sit near the front of the lecture hall. d) Office Hours: Please see your instructor or your TA during the scheduled office hours. To arrange an appointment with your instructor and/or TA outside of normal office hours, send them an email and clearly state your request. Instructor office hours are intended to help you with administrative aspects of the course, like upcoming absences and grading problems, TA office hours are intended to help you understand the material, guide you with problem solving and assist with take home quiz and exam problems. To succeed in this course, work regularly and approach the course and material with a positive attitude. If you have difficulties in the course, see you instructor or TA as soon as possible about these difficulties. Do not fall behind. ACADEMIC INTEGRITY is an essential component of your education. The following is quoted from the PSU Faculty Senate Policies for Students. It is the pursuit of scholarly activity free from fraud and deception and is an educational objective of this institution. Academic dishonesty includes, but is not limited to, cheating, plagiarizing, fabricating of information or citations, facilitating acts of academic dishonesty by others, having unauthorized possession of examinations, submitting work of another person or work previously used without informing the instructor, or tampering with the academic work of other students. All University and Eberly College of Science policies regarding academic integrity/academic dishonesty apply to this course and the students enrolled in this course. Refer to the following URL for further details on the academic integrity policies of the Eberly College of Science: http://www.science.psu.edu/academic/integrity/index.html. Matters of academic dishonesty will be turned over to the University disciplinary system and may result in the failing of the course. xiv
