OSHA regulations for personal safety NO Food or Beverages of any kind allowed. Students MUST wear the provided LAB COAT and CHEMICAL SAFETY GOGGLES at all times. NO SHORTS or SANDALS. If this is not adhered to you will be dismissed from lab.
CELL PHONES, iPODS, HEADSETS and other ELECTRONIC DEVICES: Prior to entering lab all electronic devices must be turned off and put away. (unless you are recording the lab instructionslecture to help you study). Headsets are to be removed.
CIVILITY: Each student is expected to be courteous to fellow students and the instructor. There is to be no talking when the instructor is speaking or when students are asking questions. During the lab quiz and lab instructions, students are not to arbitrarily leave and come back to lab. When graded papers are passed back, students are to respectfully discuss any questions privately with the instructor.
TUTORS: Chemistry tutors are available at the Academic Excellence Center (AEC) in the Library.
STUDENTS WITH DISABILITIES: Please contact Mr. David Symonds, at the AEC in the Library, to discuss special accommodations. No special accommodations will be provided until the instructor has been notified by Mr. Symonds.
ATTENDANCE POLICY:
According to the Faculty & Staff Handbook of Morrisville State College, each student is expected to attend all scheduled classes and laboratories.
Since the beginning of lab will be used to take attendance, administer a quiz, and give instructions, it is imperative that you come to lab on time.
If an absence is unavoidable, it is the student's responsibility to notify their lab instructor immediately so arrangements can be made to attend another lab section. The student must get Permission from the instructor BEFORE attending another lab section. A student may NOT make up more than TWO (2) LABS during the semester this way.

If you miss a week's lab it will NOT be possible to make-up the work. However, the lowest lab quiz and lab report grade will be dropped at the end of the semester to compensate for an unavoidable absence.
If you miss a week’s lab you are responsible for reading over the lab missed and ask any questions beforehand in preparation for the quiz that will be administered the following week.
If you miss a week’s lab submit the prelab and lab report that was due during your absence to your lab instructor by the next lab period.
You must be in lab and perform the lab experiment in order to turn in the lab report for that exercise.
ACADEMIC HONESTY: Keep in mind that assignments are given to allow you to demonstrate what you have learned in class as well as show off your own creativity.
Each assignment is therefore expected to be your own original work.
Any work that is determined by the instructor to be dishonest in any form will be treated according to the standards for Academic Honesty as described in Morrisville State College Student Handbook and Faculty/Staff Handbook Academic dishonesty From Wikipedia, the free encyclopedia
Fabrication is the falsification of data, information, or citations in any formal academic exercise. This includes making up citations to back up arguments or inventing quotations. Fabrication predominates in the natural sciences, where students sometimes falsify data to make experiments "work". It includes data falsification, in which false claims are made about research performed, including selective submitting of results to exclude inconvenient data to generating bogus data. There is also the practice of dry-labbing—which can occur in chemistry or other lab courses, in which the teacher clearly expects the experiment to yield certain results (which confirm established laws), so the student starts from the results and works backward, calculating what the experimental data should be, often adding variation to the data. In some cases, the lab report is written before the experiment is conducted—in some cases, the experiment is never carried out. In either case, the results are what the instructor expects.
Deception is providing false information to a teacher/instructor concerning a formal academic exercise. Examples of this include taking more time on a take-home test than is allowed, giving a dishonest excuse when asking for a deadline extension, or falsely claiming to have submitted work. This type of academic misconduct is often considered softer than the more obvious forms of cheating, and otherwise-honest students sometimes engage in this type of dishonesty without considering themselves cheaters. It is also sometimes done by students who have failed to complete an assignment, to avoid responsibility for doing so.
Cheating can take the form of crib notes, looking over someone's shoulder during an exam, or any forbidden sharing of information between students regarding an exam or exercise. Many elaborate methods of cheating have been developed over the years. For instance, students have been documented hiding notes in the bathroom toilet tank, in the brims of their baseball caps, or up their sleeves. Also, the storing of information in graphing calculators, pagers, cell phones, and other electronic devices has cropped up since the information revolution began. While students have long surreptitiously scanned the tests of those seated near them, some students actively try to aid those who are trying to cheat. Methods of secretly signaling the right answer to friends are quite varied, ranging from coded sneezes or pencil tapping to high-pitched noises beyond the hearing range of most teachers. Some students have been known to use more elaborate means, such as using a system of repetitive body signals like hand movements or foot jerking to distribute answers (i.e. where a tap of the foot could correspond to answer "A", two taps for answer "B", and so on). Cheating differs from most other forms of academic dishonesty, in that people can engage in it without benefiting themselves academically at all. For example, a student who illicitly telegraphed answers to a friend during a test would be cheating, even though the student's own work is in no way affected. Another example of academic dishonesty is a dialogue between students in the same class but in two different time periods, both of which a test is scheduled for that day. If the student in the earlier time period informs the other student in the later period about the test; that is considered academic dishonesty, even though the first student has not benefited himself.
Impersonation is a form of cheating whereby a different person than the student assigned an assignment or exam completes it. Unlike in Cheating, the academic work is totally 'outsourced' to another person or organization, usually for pay GRADING POLICY:
Grades are NOT negotiable. There is NO extra credit; Grades are based on quality not quantity. Grades are not curved. Students may not attend Lab to just take a quiz and leave; if so it will be counted as a zero. Grades are EARNED by the quality of knowledge you learned from lab and lecture as demonstrated by Lab quizzes and lab reports.
% of Lab Grade 40% Reports: Pre Lab Questions (50 pts) & Results (50 pts) 60% Quizzes (100 pts)
Example: Lab Quiz average 75 x 0.60 = 45.00 Lab report average 85 x 0.40 = 34.00 79.00 = B-
Prepare for each laboratory period by reading each exercise and by becoming familiar with the principles and methods involved. Familiarity with the exercise decreases your chances of an accident. In addition, advance preparation allows you to use your time efficiently to complete the exercise.
Pre-lab questions will be included on your weekly quizzes.
Completed reports are to be turned in at the beginning of the laboratory session, as you enter the room.
Late reports will NOT be accepted.
Papers submitted without a name will receive a zero
Because of the nature of the materials used, if you miss a week's lab it will NOT be possible to make-up the work . However, the lowest quiz and lab report grade will be dropped at the end of the semester to compensate for an unavoidable absence.
The following scale will be applied in determining your final letter grade for Lab. A grade of “D” is a passing grade, but will not transfer. Grades are rounded to the next letter grade (e.g. 92.5 is rounded to a 93 “A”; a 92.4 remains a 92 “A-“)
93 - 100% A 89 - 92 A- 85 - 88 B+ 82 - 84 B 78 - 81 B- 74 - 77 C+ 70 - 73 C 66 – 69 C- 63 - 65 D+ 60 - 62 D 0 –59 F FALL 2011
