All times by appointment.
Any student who, because of a disabling condition, may require some special arrangements in order to meet course requirements should contact disAbility Services (Student Service Center room 119, phone 371-5436) as soon as possible.
As a student you may experience a range of issues that can cause barriers to learning, such as strained relationships, increased anxiety, alcohol/drug problems, feeling down, difficulty concentrating and/or lack of motivation. These mental health concerns or stressful events may lead to diminished academic performance or reduce a student's ability to participate in daily activities. Amarillo College offers services to assist you with addressing these and other concerns you may be experiencing. If you or someone you know are suffering from any of the aforementioned conditions, you can learn more about the broad range of confidential mental health services available on campus by calling the AC Counseling Center at 806-371-5900. The AC Counseling Center website is https://www.actx.edu/counseling/ .

In order to receive your AC Connect Email, you must log in through AC Connect at https://acconnect.actx.edu .
If you are an active staff or faculty member according to Human Resources, use "Exchange". All other students, use "AC Connect (Google) Email".
\ Please turn off your cell phones and pagers before class begins. If it is necessary to have a phone or pager on, please see me about it during the first week of class.
\\ All students are required to wear goggles at all times in the laboratory. There are absolutely NO EXCEPTIONS! Plastic aprons are also required to be worn in the laboratory. No shorts, no sandals or other open type shoes. Pants must cover the knees. Your feet must be covered at all times with closed shoes. Muscle shirts, half shirts, and mini-skirts are strongly discouraged. Baseball hats and other types of hats are not allowed in the laboratory. No food or beverages are allowed in the laboratory at any time. These rules are for your safety as you learn to work in the laboratory. Failure to comply with safety regulations will result in dismissal from class.
\\ Cheating – If a student is caught cheating on a quiz or an exam in this class, the quiz or exam will be taken up and a grade of zero will be assigned for that item. The grade assigned for cheating may NOT be the grade dropped!
\\ Tobacco and Tobacco Products Use – According to the Student Rights and Responsibilities document, tobacco and tobacco use is prohibited inside college buildings. This includes smokeless products (i.e. chewing tobacco) as well as cigarettes, pipes, and cigars.
\ The safety quiz will be taken during the first lab period. A grade of 80% or higher must be obtained in order to attend the rest of the laboratories. Failure to take the safety quiz and pass it stops you from completing lab. There will be a comprehensive written final exam. During the term, there will be short prelab quizzes over most experiments, and a mid-term "practical" lab exercise. The final grade will be determined by the grades on your laboratory reports, your quizzes and mid-term exercise, post-labs, and the final exam. Prelabs must be turned in at the very beginning of the lab period to receive credit; a zero will be recorded for any missing or late prelabs. Postlabs are due at the beginning of the next week's lab period. Points will be deducted for late postlabs. Lab reports are normally due before leaving the laboratory; however, in the case of some longer labs students may be allowed to finish calculations at home. In those cases, points will be deducted for turning them in later than the due date announced in class. Students arriving late to lab after the prelab quiz has been given out will not be allowed to take the quiz. In the case of prelabs, postlabs, and quizzes, the lowest grade will be dropped in each category. The midterm and final cannot be dropped.

\ It is important that you do not miss a lab. There are no make-up labs. Your lowest lab report grade will be dropped when calculating the final grades. If you miss a lab, that will count as your drop grade. UNDER NO CIRCUMSTANCES WILL THE INSTRUCTOR BE RESPONSIBLE FOR DROPPING A STUDENT FROM THE CLASS!
