LAB NOTE BOOKS: It is important and beneficial to keep a legible and up-to-date note book. You will be allowed to use your laboratory note book during your laboratory final. However, you may not cut and paste the theory from the experimental procedure handouts into your lab note book. The signature grades are to encourage you to bring your lab note book to class.
FORMAL LAB REPORTS: See pages 1 through 3 in the Laboratory Manual for information regarding the formal laboratory reports.
LABORATORY MANUAL: 152 General Chemistry, 2006/2007 Edition

ATTENDANCE: The Maricopa Community College District requires class attendance. More than three unexcused absences may result in a student being dropped from the course. Although attendance is required, the instructor is aware that unavoidable situations, such as illness, transportation problems, family emergencies, etc., may arise that require a student to miss a class. In the event of such an emergency, the student should call one of the phone numbers listed above the same day of the scheduled class, and the absence will not be counted against the student. If an exam is missed due to an unexcused absence, a make-up test will only be given at the discretion of the instructor. Make-up exams will only be available for one week following the administration of the original test.
MAKE-UP EXPERIMENTS: If you miss a lab it may be possible to make up the lab by attending a different section that is performing the same experiment. You must get a Permission to Make-Up Laboratory Work Form from the stockroom. Stockroom personnel can also help to determine when there are sections that will be doing the same experiment. Have your instructor and the instructor of the section you attend sign the form and attach it to your lab when you hand it in.
CLASSROOM HONESTY AND INTEGRITY: Nothing says more about a person than his or her honesty and integrity. Since students compete with one another for grades and positions in degree and training programs, cheating is considered a serious offense. Students should consult with the student handbook or the catalog to review the policies and consequences of cheating. Rather than resort to such tactics, a student should contact the instructor and see if some extra help may resolve any problems in the course.
DISABILITY ACCOMODATION: If a student requires special accommodations due to a disability, please contact Disability Resource Services at (480) 461-7447. Be assured that I am willing to make any reasonable accommodations for limitations due to any professionally diagnosed disability, including diagnosed learning disabilities. However, no special accommodations can be provided until a completed Instructor Notification Form is received by your instructor from Disability Resource Services. Please note that it is the responsibility of the student to make all necessary arrangements in order for accommodations to be provided.

PHONE QUIZZES: Ringing or noisy cell phones and beeping pagers often disrupt class. If the class is disrupted with one of these devices, a phone quiz will automatically be given at that time and will cover material that should have been read before class. Continued abuse Will Obviously result in more and harder quizzes.
THE DISRUPTIVE STUDENT: Noisy and obnoxious behavior will not be tolerated in this classroom. If you feel that your learning is compromised by these disruptive students, you need to inform me of the situation. Those disruptive students will first be warned, if necessary removed from the classroom (by security) , and ultimately dismissed from the class with a Y.
