Syllabus

Chemistry 102 is the one credit hour laboratory course to accompany Chemistry 101- Chemistry: A Molecular Science (CAMS). CH 102 is a separate course, for which you get a separate grade. CAMS teaches basic chemical concepts though a complete survey of the subject in a stepwise, logical fashion. In the lecture course, mathematical calculations are held to a minimum while concepts and trends are emphasized. In the laboratory course we will follow this same philosophy as much as possible but more calculations will inevitably be utilized in order to demonstrate the concepts and trends. Although the topics covered in this course follow the same general order as the CH 101 textbook, this lab course is not meant to follow the lecture course on a day-by-day basis. It is also not just a supplement to the lecture. Please consult your textbook and the lab website often for additional information on the topics covered in lab.

Corequisite:

CH 101: This is the lecture course and you are required to register for it in the same semester that you are taking CH 102.

Section Information:

Finding your section of CH 102 is important. Check your registration information on TRACS a day or two before your first lab. Write down the section number, room number, and instructor's name, and bring them to lab. Once in lab, make sure you are in the right place. Also, make sure you are on the official roll for the section.

Class Policies

Attendence:

It is mandatory that you attend laboratory during your assigned section each week, since there are no makeup laboratories. In order that you are present for the prelab presentation by your laboratory instructor, you should plan to be in the assigned laboratory on time. Students who are more than 10 minutes late for lab will have an unexcused absence for the laboratory session.

Absences:

Excused absences: The University requires that absences due to illness, certain university-sponsored activities, deaths in one's immediate family, and court appearances be excused. Your instructor will require documentation for any of these. If you know you must miss a lab, contact your instructor as soon as possible. If you miss a lab due to illness or other unforeseen circumstances, you must contact your instructor within 24 hours or the absence will not be excused. Instructor contact information and procedures for addressing excused absences are available at http://courses.ncsu.edu/ch102/.
Consequences of absence:
• Missing a lab does not excuse you from completing the WebAssign prelab and postlab assignments. You may use "representative data" obtained from another student (ideally your usual lab partner) or your instructor to complete your postlab assignment. You are not allowed to receive credit for the inlab assignment with an unexcused absence.
• There is no provision for a score of INCOMPLETE in CH 102. If you cannot attend at least nine of the eleven sessions, you must drop the course. To drop a course after the deadline, a Schedule Revision Form with the student's dean's approval is needed. More information can be found in the on-line Student Handbook, REG02.20.2, Adding and Dropping Courses.

Adverse Weather Policy:

In adverse weather, if the University closes, classes are cancelled. If the University has announced that it is operating under the Adverse Weather Policy, labs are cancelled. No make-ups will be scheduled. However, students are responsible for the WebAssign exercises. "Representative data" for the experiment will be sent to you by email or will be posted in the WebAssign in-lab for your use.

Assignments:

Each experiment, except the first, has three WebAssign exercises, a Prelab (25 points), an In-lab (50 points), and a Postlab (25 points). The first lab has a Syllabus Quiz in lieu of the prelab. Therefore, the total point value for each experiment is 100 points.
Syllabus quiz: An assignment to check your knowledge of course rules.
  • •
    Due at 11:00 PM one day after your first lab meeting.
  • •
    Covers the Introductory Material section of the CH 102 lab manual.
  • •
    The quiz is worth 25 points and there are three submissions.
Prelabs: Assignments that prepare you for the lab experiments.
  • WebAssign Prelab:
    • •
      Due at 11:00 PM the day before your lab meeting. There is no prelab for the first lab.
    • •
      Covers safety, waste disposal, lab procedures and background theory.
    • •
      Prelabs are worth 25 points and there are three submissions.
    The prelab exercises are an important part of your preparation for the laboratory. The first two questions will cover safety and waste disposal information, and you must answer them correctly to be admitted to lab. Students who do not complete their WebAssign prelab must have their instructor check the answers on their written prelab before proceeding with lab experiments.
  • Written Prelab:
    • •
      Due near the beginning of your lab.
    • •
      Covers safety, waste disposal, lab procedures and background theory. Questions are similar to those found in the Webassign prelab assignment.
    • •
      Your TA may call upon you to answer questions from the written prelab during their short prelab presentation. Your prelab will be turned into the TA as a record of your attendance.
In-Labs: Assignments you should try to complete during your lab period.
  • •
    Due at the end of the lab period.
  • •
    Covers data entry, observations and checks results.
  • •
    In-labs are worth 50 points and there are three submissions.
The In-Lab exercises cover the same material as your Data Tables and In-Lab Questions, and allow your work to be graded automatically. The last question is an essay-type question in which you enter your name. It is worth 15 "discretionary points" that relate to your performance in lab. If you have completed your prelab, followed the rules about safety glasses, attire, clean up, and performed your work reasonably well, you will earn all of them.
Postlabs: Assignments that are essentially lab reports.
  • •
    Due at 11:00 PM two days after your lab meeting. This will allow you time to visit the tutorial center with your questions.
  • •
    Covers observations, results, conclusions and extensions of lab concepts.
  • •
    Postlabs are worth 25 points and there are three submissions.
  • •
    If you missed a lab, get "representative data" from your lab partner or instructor to complete the postlab assignment.
Late WebAssign Prelab and Postlab Assignments:
Students with university-accepted documentation may receive extensions on prelab and postlab assignments. Students without documentation may have one full point extension per semester. Additional extensions cost 10 points per assignments. Excessive extensions are not allowed.
Grading (no curve is used):

Honor Code:

Duplication of another person's lab assignment is academic dishonesty and will be treated as such. This includes getting data from another student before performing the lab or typing unauthorized lab data into WebAssign from a non-lab location! The grade for an experiment in which academic dishonesty has occurred is recorded as a zero and reported in a manner consistent with the University's policy on academic dishonesty. The University's Code of Student Conduct can be found at http://www2.ncsu.edu/prr/student_services/student_conduct/POL445.00.1.htm.
All members of the University community: students, faculty, and staff, share the responsibility and authority to challenge and make known to the appropriate authority acts of apparent academic dishonesty.

Each Week When You Come to Lab

Check-In

During check-in for your CH 102 lab, the following things will happen. Make sure you pay attention, some of them are very important.
  • 1
    Roll will be taken. Make sure you are in the right section, or your work will go to two different instructors. One will get your lab work and the other will see your WebAssign work. If you are not sure you are in the right place, check with your instructor or the lab coordinator. Once you are in a section, do not switch out of it without the permission of the lab coordinator. If you do, you risk having some of your grades lost.
  • 2
    You will be issued safety glasses. Safety glasses are to be worn at all times while you are in lab, over your regular glasses if you wear them. Wearing contact lenses in the lab is strongly discouraged. If you wear them, you will be asked to sign a waiver stating that you understand the dangers in doing so, and will not hold the university liable if you are injured as a result of wearing contact lenses in the lab.
  • 3
    You will be shown the location of safety devices and how to operate them. These devices will include eyewashes, safety showers, drench hoses, and fire extinguishers. Safety policies in the lab will be explained, and you will be asked to sign a form saying you understand the rules and agree to abide by them.
  • 4
    You will be shown the evacuation route for a fire. Make sure you understand how to exit the building safely. In a fire evacuation, it is important to get well away from the building.
  • 5
    You will be asked to fill out the Medical Information Form in the Introductory Material of this lab manual. This form lists chronic medical conditions, medicines you are taking, and who to contact in an emergency. This form will remain private, and will not be viewed unless you are injured or ill in the lab and unable to provide information for yourself.
  • 6
    Policies regarding grading and attendance will be explained. Make sure you pay attention, as your instructor may have specific policies for the sections he/she teaches, e.g. point penalties if you leave your workspace a mess, or your lab work is illegible.
