2 Academic Integrity: Cheating, plagiarism, and falsification/fabrication of laboratory data are unacceptable practices, and are in violation of the Academic Honesty policy at Los Angeles Valley College. All students involved in an instance of academic dishonesty will be disciplined according to the actions outlined in the Los Angeles Valley College Catalog, pg In the least, all students involved in an incident will receive zero points for the assignment/exam. Additionally, the offender will be referred to the Vice President of Student Services for further disciplinary action, following due process. For further information, review the Los Angeles Valley College Policy on Academic Dishonesty and the Standards of Student Conduct and Disciplinary Action. Academic dishonesty includes copying the answers of homework and laboratory assignments. Students who allow their assignments to be copied are also guilty of violating the Academic Honesty policy at Los Angeles Valley College. Regardless of the extent of participation, all instances of academic dishonesty will result in the penalties described above. Disability Services: Los Angeles Valley College is committed to providing educational accommodations for students with disabilities upon the timely request by the student to the instructor. Services for Students with Disabilities (SSD) program functions as a resource for students and faculty in the determination and provision of educational accommodations. SSD is located in the Student Services Annex, Rm 175 and its contact information is: (818) or TTD (818) and SSD@lavc.edu. If SSD has already sent the memo to instructor confirming accommodations required by student for this class, please meet with me to discuss arrangements. Emergency Response: In the event of an emergency, students must evacuate the building as directed by the instructor and must follow all safety instructions. Please take note of the safety features in and close to your classroom, as well as study the posted evacuation route. The most direct exit route may not be the safest because of the existence of roofing tiles or other potentially hazardous condition. Similarly, running out of the building can also be dangerous during severe earthquakes. During strong quakes the recommended response is to duck cover and hold until the shaking stops. Follow the guidance of your instructor. You are asked to go to the designated assembly area. Your cooperation during emergencies can minimize the possibility of injury to yourself and others. Important Dates: Last day to add and audit Last day to drop without receiving a W grade Last day to drop with a W grade Friday, Sep 8 th in-person and Sep 10 th online Sunday, September 10 th online Sunday, November 19 th Grading Policy: Regular attendance and participation is required for this course.

3 Online Homework: [ MasteringChemistry Course ID: MCHAJJAWI86588 ] Generally, it is not possible to succeed in a chemistry course without doing a significant number of problems. For this reason, homework assignments will be assigned for each chapter. The problems, found in your textbook, will be answered online at MasteringChemistry.com. Homework problems not submitted before the due date (and time) will be subject to a deduction of the available points. Although the problems are answered online, you should write out the work and answers to all of the problems in a notebook (or on loose sheets of paper). This will provide a record for you to study from, and it will help when asking questions, such as during help sessions or the instructor s office hours. Additionally, having a permanent record of the problems that you have solved will make it easier to prepare for the examinations. Laboratory: Please see below for a description of the laboratory portion of this course. Problem Solving: The ability to correctly set-up and solve problems is an integral part of chemistry. The problem solving session represents an excellent opportunity to have questions answered about the homework and lecture material. Students will be expected to work in groups to solve worksheets and/or online problems that relate to the material being studied in lecture. The score earned for problem solving will be based on participation and completion of the assigned material. Exams: You are expected to take all three exams and the final exam. Each exam will begin at the start of the lecture period and students will have the entire lecture class period to complete the exam. No Make-up exams will be given without a valid excuse approved by me; a missed exam will be given a score of zero. Final Exam: A cumulative final exam will be given during the last week of the semester. Refer to the attached schedule for the final exam date. You may submit your work to be re-graded if at any time you feel as though I have made a mistake or have graded you unfairly. Work that is to be re-graded must be submitted within one week; a written description of the mistake/complaint may be required for some assignments. All items submitted may be examined in their entirety. It should be noted that this could potentially result in a lower grade than given originally. All electronic communication devices must be put on silent mode during class and lab times. Failure to follow this policy will result in a verbal warning for the first offense and expulsion from the class for the duration of the day for the second offense.

4 General Chemistry I CHEM 101 Laboratory Guidelines The majority of points earned in the laboratory section will be associated with the laboratory reports. When student reports are collected after an experiment, a grade is assigned based on the quality, organization, and completeness of the work contained inside. You must bring your lab report for the assigned experiment to lab meetings and do all work directly into the report in ink. Never erase or use white-out. If you make a mistake, simply draw a line through the entry. Never write on loose notebook paper or paper towels. While discussion and exchange of ideas is encouraged, your lab write-up must be done in your own words. Each laboratory report will be worth fifteen points. The lab reports are due the following lab meeting unless otherwise stated. A lab report will be docked 20% of the total possible points for each day it is late. The laboratory is a critical aspect of this course. Your attendance and participation is required; a missed experiment will result in the loss of all points for the experiment. The laboratory score is worth 20% of your overall grade in the class. Laboratory Cleanliness: Each student is responsible for leaving his/her lab space clean and tidy. At the end of each lab, students should put glassware back into the lockers, wipe off hood stations with a damp sponge, and make sure all items in their lockers clean and ready for use the following lab. Points will be deducted for leaving a messy station. Attendance Policy: Attendance at your regularly scheduled lec/lab section is mandatory. Labs will begin promptly at the start of the lab period. There will be no make-up labs, and experiments may not be performed early. No student may enter the lab unless accompanied by an instructor. If you stop attending (or wish to drop the class), you must drop the class yourself officially over the Internet before the deadline (see Schedule of Classes). Failure to do so may result in a grade of "F" in the course. Safety Regulations: The safety of yourself and your classmates is of paramount importance during laboratory. Safety regulations must always be observed as it only takes one accident to cause a serious permanent injury. Safety in the laboratory will constantly be emphasized. In addition to viewing a video on laboratory safety, students will be required to read the laboratory safety rules in the Chemistry 60/68 Lab Manual (Introduction) and Safety in Academic Chemistry Laboratories-Volume 1 (ISBN: ) and sign a laboratory safety agreement. Failure to follow the laboratory safety rules will result in the loss of points and/or dismissal from laboratory. -Always wear splash goggles when working in the lab. -Wear closed-toed shoes (no heels or sandals) in the lab. -Never remove materials from the lab. -No food or drink is allowed in the lab. 4
