The Tutoring for Success policy applies to any student whose grade or performance in the course falls below a departmentally determined minimum threshold. In either of those cases, the instructor will direct the student to the appropriate tutoring service, which may be faculty-led, discipline-specific, and/or general. Under this policy, the instructor will follow specific departmental guidelines governing the use, duration, and grade component of the tutoring need.
Students who do not attend class on or prior to the census date will be administratively dropped. Effective Fall, 2016
Students who wish to withdraw from a course must complete all steps indicated on the Academic Withdrawal Request form by the course withdrawal deadline.
NOTE: Students who are attending Texas institutions of higher education, for the first time fall 2007 and later, may not withdraw from more than six courses during their academic career. This withdrawal limitation does not include dual credit or developmental classes (Senate Bill 1231 Rule 4.10.) For more information on Drop and Withdrawal Policies, please visit the Registrar's Office Web site.

(1 sem hr; 3 lab)
On Campus Course
Laboratory Manual: Principles of General Chemistry, A. G. Foster, 2003 Revision
safety goggles, Lab. coat or apron, pencil, pen, scratch paper, calculator
Upon successful completion of this course, students will:
1. Use basic apparatus and apply experimental methodologies used in the chemistry laboratory.
2. Demonstrate safe and proper handling of laboratory equipment and chemicals.
3. Conduct basic laboratory experiments with proper laboratory techniques.
4. Make careful and accurate experimental observations.
5. Relate physical observations and measurements to theoretical principles.
6. Interpret laboratory results and experimental data, and reach logical conclusions.
7. Record experimental work completely and accurately in laboratory notebooks and communicate experimental results clearly in written reports.
8. Design fundamental experiments involving principles of chemistry and chemical instrumentation.
9. Identify appropriate sources of information for conducting laboratory experiments involving principles of chemistry.
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".
Safety equipment must be worn at all times: long pants/skirt (covering at least the top half of the calf), apron or lab coat, hair back, safety goggles, and, if necessary, gloves. No open-toed shoes, shoes with holes in them, shoes that leave the top of the foot exposed, hats of any sort, shorts, food or drink are allowed. Anyone acting in an unsafe manner will be warned once. If seen without safety equipment or acting improperly a second time, they will be asked to leave the laboratory. They will be allowed to return in 30 minutes to finish their work, if they can. If they are asked to leave more than once for any given experiment, they will receive a zero for that experiment’s lab report. Safety is the MOST important part of lab. You must attend the safety lecture and pass the safety quiz before you will be allowed to perform experiments for lab. Any experiments missed by failing to do this will be zeroes and cannot be made up.
Use of previous semester’s work, from whatever source, is considered cheating. If you have access to such papers, turn them in to the instructor at the beginning of the semester and they will be returned at the end. If a student is seen to be using any other student’s work, past or present, they will receive a zero grade for that assignment and it cannot be dropped.
Please read and abide by the Student Rights and Responsibilities Handbook.
AC Connect/Gmail: Email contact will be made in AC Connect (via Gmail). You must check your email there daily.
Grading criteria: Prelab + postlab + report 60%, Quizzes 20% and Final exam 20%
You must have completed and turned in the pre-lab from the text at the beginning of the lab period in order to be allowed to do the lab—you MUST come to lab prepared. This means all blanks must be filled in with reasonable answers to be allowed to complete the experiment. Generally, completion will be assessed during the experiment, but if you turn in an experiment with an incomplete pre-lab, you will receive a zero. If you arrive tardy and have missed too much of the pre-lab lecture (as determined by the instructor) you will not be allowed to begin the experiment. Please, arrive ON TIME to avoid a zero grade. The Prelab + postlab + report (stapled together) is due at the beginning of next lab. No late work is accepted. Exact criteria for grading lab reports will be discussed during the lab. Dropping the course is the sole responsibility of the student.
There are no make up labs
You must clean up your area of the lab. It is not the instructor’s or Mr. Sims’s job to clean up after you. Failure to leave a clean lab will result in a 10 point deduction on your lab report for that week. If the lab in general is left messy rather than an individual’s area, the whole class may be docked points on their lab report.
All grey areas of the lab reports must be in pen, only. Whenever writing data or observations down, it must be written directly into your lab book. Scratch paper may be used for calculations, if necessary, but if instructed to show all work, you must include it with the lab report. You CANNOT write data (such as weights, measurements, etc.) on scratch paper then copy it into your lab book. If you make a mistake while writing in pen, simply cross it out once and write the correct number in close-by. Do NOT use correction fluid or tape. If you do make a correction, you MUST come to the instructor and show him the correction so that he can approve it. Please write legibly: if I can’t read an answer, it is wrong.
Some possible areas to lose points in lab reports:
no prelab turned in/insufficient answers (10 pointts)
no post lab turned in with the report (10points)
not cleaning up lab [10 points]
writing in pencil in grey area (5 points)
error in experimental value [variable (depends on class average, etc.)]
missing labels/units [1 point]
calculation errors [5 points]
not showing all work when asked [receive no points for that question/part of the lab]
All students are required to clean their laboratory equipment and check out of their locker. Failure to check out of your locker will result in one letter grade deduction for the course. Failure to officially withdraw will result in a grade of F. Grades are based on 90.00+ = A, 80.00-89.99 = B, 70.00-79.99 = C, 60.00-69.99 = D, and 59.99 and lower = F.

Efficient Use of Time: Please be aware that this class is schedules from 7:00 pm until 10:20 pm. This is generally more than enough time to finish most labs. Several labs are marked as short and you can generally assume getting out early on those days. One lab is marked long and could easily run over for many students. Other than those, expect to be in lab until 3:30 at least.
INFORMATION SHEET/SIGNATURE: You must fill out and return the information sheet for this class (handed out and posted in AC Online). You must also sign it to signify that you have read and understand the syllabus. No graded assignments will be returned to you and you will not be shown your overall grades until the signed information sheet is turned in.
***This syllabus is subject to change. You will be informed of any changes to the syllabus in class, email, and posting in AC Online.***
