In the event of an emergency or announced campus closure due to a natural disaster or pandemic, it may be necessary for Panola College to move to altered operations. During this time, Panola College may opt to continue delivery of instruction through methods that include, but are not limited to: online learning management system (CANVAS), online conferencing, email messaging, and/or an alternate schedule. It is the responsibility of the student to monitor Panola College's website (www.panola.edu) for instructions about continuing courses remotely, CANVAS for each class for course-specific communication, and Panola College email for important general information.
Regular and punctual attendance of classes and laboratories is required of all students. When a student has been ill or absent from class for approved extracurricular activities, he or she should be allowed, as far as possible, to make up for the missed work. If a student has not actively participated by the census date, they will be dropped by the instructor for non-attendance. This policy applies to courses that are in-person, online, hybrid, and hyflex.
Attendance in online courses is determined by submission of an assignment or participation in an activity. According to federal guidelines, simply logging into a distance learning course without participating in an academic assignment does not constitute attendance. Distance learning is defined as when a majority (more than 50%) of instruction occurs when the instructor and students are in separate physical locations. Students must engage in an academic activity prior to the course census date.
When an instructor feels that a student has been absent to such a degree as to invalidate the learning experience, the instructor may recommend to the Vice President of Instruction that the student be withdrawn from the course. Instructors may seek to withdraw students for non-attendance after they have accumulated the following number of absences:
Fall or spring semesters:
3 or more class meeting times per week - 5 absences
2 class meeting times per week - 3 absences
1 class meeting per week - 2 absences
The student is responsible for seeing that he or she has been officially withdrawn from a class. A student who stops attendance in a class without officially withdrawing from that class will be given a failing grade; consequently, the student must follow official withdrawal procedures in the Admissions/Records Office.
Please note: Health Science and Cosmetology courses may require more stringent attendance policies based on their accreditation agencies. Please see the addendum and/or program handbook for further information concerning attendance.
Panola College welcomes pregnant and parenting students as a part of the student body. This institution is committed to providing support and adaptations for a successful educational experience for pregnant and parenting students. Students experiencing a need for accommodations related to pregnancy or parenting will find a Pregnancy and Parenting Accommodations Request form in the Student Handbook or may request the form from the course instructor.
No use of Generative AI permitted.
This option assumes that all work submitted by students will be generated by the students themselves, whether they are working individually or in groups. Students should not have another person or entity do the writing of any portion of an assignment, which includes hiring a person or a company to write assignments and/or using artificial intelligence (AI) tools like ChatGPT. Use of any AI-generated content in this course qualifies as academic dishonesty and violates Panola College’s standards of academic integrity.

This course is offered in the following formats:
FACE-TO-FACE: Pre-laboratory activities, laboratory experimentation, and laboratory reports
ONLINE: Pre-laboratory activities, laboratory experimentation and laboratory reports. The manner in which material is presented, assignments are assigned and collected, and grading may change or vary from face to face class methods.
Laboratory Experiments:
- FOR LAB STUDENTS WHO ATTEND LABS AT PANOLA COLLEGE - Laboratory experiments will be performed in order to apply the general principles, laws and theories of chemistry learned during lecture.
o Experimental results will be recorded and submitted on the form provided in lab. The laboratory course information and specific procedures will be provided and discussed in the mandatory laboratory orientation by your lab instructor.
o No student will be allowed to begin any experiments in the lab without going through lab orientation AND without the pre-lab reports-assignments being completed. The lab instructor has the authority to remove 10 points from your laboratory report for each expectation in the laboratory guidelines that is not followed by the student.
o Removal of points or removal of the student from class is by instructor discretion and based on previous warning or the gravity of the infraction. NO ONE WILL BE ALLOWED TO PUT YOU OR OTHERS AT RISK IN THE LAB.
Students must follow all expectations as described in the Lecture and Laboratory course information document in order to remain in lab class. This section specific syllabus is located in Canvas. One copy will be given to all face to face students. Safety is most important.
The grade of 100 possible points for each laboratory experiment is broken down as follows:
- 20 possible points for showing up on time with the pre-lab assignment complete; as assigned in Canvas or otherwise by your instructor. The pre-lab assignment may include a pre-lab report assignment , a pre-lab quiz and MSDS information. This is your ticket in the door and you will not begin an experiment without having met all of the requirements. This also includes conducting the experiment, adhering to all safety and equipment use rules, completing the experiment, cleaning up your lab station, and disposing of all waste/trash according to instructions given. All of these items must be complete before leaving lab, if incomplete, 10 points will be removed. In order to receive the above 20 points in the grade book, the required documentation must be turned in with lab instructor initials.
- 80 possible points for the Lab Report Sheet(s) you turn in. It must be complete, legible, and information must be properly presented and clearly explained when necessary. All work must be shown when necessary to receive full credit.
Missing a lab:
o No more than 2 missed labs may be made up. No exceptions, reason doesn’t matter.
o The missed lab must be made up within 7 days of the original lab date.
o It is the student’s responsibility to make arrangements, time and date, with the lab instructor to make up the missed lab. No additional make up lab times will be available. Once the new lab is set up, previous labs will not be offered for make-up.
Cell phones in lab- NO CELL PHONES IN LAB!!!!!
o If you have a situation where you may need to take a call, then you will leave the phone at the instructor table to be answered by you when/if it rings. If you have your phone out or are using your phone without permission for any reason, you will lose all points of your participation grade but are required to complete the experiment.
o This is a violation of safety rules and putting others or you at risk will not be tolerated.
