Office Hours:  10-11am MWF in PHY78

 

Course Objectives: Chemistry 1A is an general course in chemistry designed not only for chemistry majors, but also for biology, physics, chemical engineering, pre-medical and pre-pharmacy majors.  As a prerequisite students need to have passed CHEM10, or High School chemistry, with at least a C grade as well as basic algebra (Math 103).

 

Textbook:          Nivaldo J. Tro: Chemistry: A Molecular Approach (either 1^st or 2^nd Edition). A softcover, customized version of this book is available at our bookstore with just the first half of the book that will be used in CHEM1A. A softcover version of the second half of the book will be available for CHEM1B next semester.

Lab Manual:      Dekker: Quantitative and Qualitative Laboratory Experiments BOOK A  (not BOOK B)

Other Supplies:  A calculator is required (needs exponents and logs, but not a programmable calculator)

                           Approved safety glasses, lab coat and closed shoes

 

Lecture Notes: Download from my Blackboard website prior to class and fill in the notes during class. Homework is assigned at the end of the notes and is due the next lecture period. Studies have shown that 90% of the lecture material is retained if you review the lecture within 24 hours.

 

Homework: Homework will be assigned every lecture, collected at the beginning of the following lecture and a few problems graded. Just before I collect the homework I will ask if there are one or two problems that you need a little help with. It is essential to your success in this class that you do all the assigned homework and read the relevant sections in your textbook. This is to ensure that you work consistently and can apply what you learn to problems. There will be no make-up homework assignments, but I will drop the lowest two homework assignments. Do not just copy homework from somebody else. You only learn by doing the homework problems for yourself. You can ask another student or tutor to help you start some problems, but you need to finish working them out for yourself. Even if you get all the problems wrong, you will still get 70% for the assignment for attempting all the problems yourself, and you will learn where you are going wrong when I go over the homework. The very latest I will accept homework is the following lecture before I start to hand back the graded homework. This is not ideal as you will not have your homework in front of you when I go over it. Absence is not an excuse for not doing homework – send it in with a friend or that will be one of the two assignments I drop.

 

Attendance: Attendance in lectures and lab is mandatory. The student will be dropped automatically if she/he misses two weeks of lectures without contacting the instructor. If you miss a lecture you need to obtain the notes to fill in from another student and read the section in the textbook before meeting with the instructor/tutor to discuss any problems. As an incentive to attend lectures, an additional two homework assignments will be dropped at the end of the semester if a student attends 90% of the lectures. If a student is disruptive (including using cell-phones, interrupting the instructor continuously) they may be asked to leave the lecture/lab and recorded as "absent".

 

Drop Date: The last day to drop this class is Friday October15, 2010. After this date a grade will be assigned.

Change to Pass/No Pass: The last day to make this change is Friday, September 17, 2010

Labor Day: Monday, September 6 (No classes held)

Veteran’s Day: Thursday, November 11 (No classes held)

Thanksgiving: Thursday and Friday, November 26-27 (No classes held)

Final Exam Date: Wednesday, December 15, 11:00-12:50. The American Chemical Society CHEM1A exam will be given (multiple choice and cumulative).

 

Grading : There will be 5 lecture exams and the final exam, equally weighted and counting 65% of your grade. Homework will count 10% and your lab work will count 25% (12.5% lab reports and 12.5% lab quizzes)

General Grading break-off : A 90-100%, B 80-89%, C 70-79%, D 60-69%, F 0-59%

 

Tutoring: Free tutoring is available at the Tutorial Center at the Library

 

Please be aware of the following rules:

• Tardiness, leaving early, or sleeping during lectures will result in a partial or full absence being recorded. Students need to sign the sign-in sheet within the first 10 minutes of class.
• Fraudulent behavior during exams is graded with a (0) zero.
• Copying of homework, experimental data, and lab reports is considered fraudulent behavior for both the copier and the originator. DO NOT HAND IN IDENTICAL HOMEWORK.
• No homework may be handed in after I have gone over it in class.  No alternative homework will be given. I will drop the lowest two homework assignments though.
• No extra credit will be given. You need to work consistently from the beginning.
• Please turn your cell phones onto “silent buzzer” mode during lectures so as not to disturb the class. No cell phones or i-pods will be allowed during exams.

 

LABS

• Safety glasses need to be worn whenever somebody near you is conducting an experiment.
• No experiments may be conducted without the instructor or teaching assistant present
• No horseplay or unauthorized experiments. Do not taste any chemical or smell any chemical directly.
• Dangerous behavior in the lab will result in the student being asked to leave the lab.
• No visitors inside the lab. You need to go outside to meet with them.
• No food or drinks allowed.
• Backpacks should not be left on the floor where others can trip over them.
• Closed shoes and lab coats must be worn in the lab at all times.
• Long hair should be tied back so it will not fall into chemicals or flames.
• If any accident occurs in the lab, inform your instructor and follow safety procedures. (To be discussed during first lab period)
• Clean up any spills promptly (Clean-up procedures will be discussed during first lab period)
• Do not point the open end of a test tube towards anybody
• Turn off flames when working with organic solvents. Dispose of them in waste bottles in the fume hood, not down the sink.
• At the beginning of each lab your instructor will inform you of any special safety precautions and how to dispose of used chemicals. You need to be on time for the lab so that you hear these instructions.
• Do not dispose of matches, paper or solid chemicals in the sink. Use the large evaporating dishes or sand bucket for spent matches.
• Put broken glassware in the “broken glassware box”, not in the trash.
• Before leaving the lab, wipe the desktop and wash your hands with soap and water.

 

If you have a verified need for an academic accommodation (especially in labs) or materials in alternate media (i.e., Braille, large print, electronic text, etc.) per the Americans with Disabilities Act (ADA) or Section 504 of the Rehabilitation Act, please contact me as soon as possible.
