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.

Statement for Mental Health and Advocacy & Resource Center:

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/ . Also, if you are in need of social services (affordable housing, utilities, transportation, food, clothing, childcare, medical/dental/vision, legal), please call the AC Advocacy & Resource Center at 806-371-5439.

Students Rights and Responsibilities

Student Rights and Responsibilities

Log in using the AC Connect Portal

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".

Expected Student Behavior

\ Conduct:  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.

\

\       Labs 12, 17, & 18 must be done with the same partner(s).  Otherwise students will be paired up by the instructor to work on lab assignments.  Partnering with a student does not give license to simply copy work/data. Please read and abide by the Student Rights and Responsibilities Handbook.

Grading Criteria

Grading:  Lab reports, 65%; Quizzes, 10%; Post-labs, 10% and Exam, 15%.  One low quiz and lab report grade will be dropped.  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 while the class takes the quiz for that experiment. Pre-labs will also be graded for correctness and incorrect answers will lower your lab report grade by up to 20 points. A weekly quiz on the pre-lab will be given at the beginning of lab class—you must be prepared for lab before coming to lab. If you are not in the classroom when quizzes are passed out, you cannot take the quiz for that experiment. If you arrive tardy and have missed too much of the pre-lab lecture (as determined by the instructor) for that week, you may not be allowed to begin the experiment and receive a zero grade for that experiment.The post-lab is due the week following completion of an experiment at the beginning of the lab period.  Lab reports will either be due at the end of the lab period or at the beginning of the following lab period, depending on the lab.  No late work is accepted.  Exact criteria for grading lab reports will be discussed during the pre-lab.  Make-up labs will occur only with prior permission of the instructor—at least a week’s notice and a valid reason for the absence.  Emergencies are the reason for a dropped lab grade.  If you miss lab, you may still turn in a post lab assignment.

Dropping the course is the sole responsibility of the student.  The last day to withdraw is April 19.

      You must clean up your area of the lab including glassware at the end of the period. It is not the instructor’s or Mr. Crofford’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 experiment.  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 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.

      All gray 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.

Some possible areas to lose points in lab reports:

            no prelab turned in/insufficient answers  [cannot do lab/receive a zero]

            incorrect answers on prelab  [up to 20 points]

            not cleaning up lab  [10 points]

            error in experimental value  [variable (depends on class average, etc.)]

Each incident of these in lab reports:

            using white-out  [5 points]

            writing in pencil in grey area  [5 points (even if you go back and write over in ink or erase)]

            not crossing out once only  [1 to 5 points]

            writing data on scratch paper  [5 points]

            failure to have cross-out approved  [5 points]

Each incident of these in lab reports and post labs:

            incorrect significant figures  [2 points]

            missing labels/units  [1 point]

            calculation errors  [5 points]

            not showing all work  [receive no points for that question/part of the lab]

Attendance

\ Attendance in the lab is required. Make-up labs will occur only with prior permission of the instructor—at least a week’s notice and a valid reason for the absence.  Emergencies are the reason for a dropped lab grade.

Calendar

Additional Information

\ Efficient Use of Time:  Please be aware that this class is schedules from 12:30 pm until 3:50 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 3:45 at least.

\

\ INFORMATION SHEET/SIGNATURE:  You must fill out and return the provided information sheet.  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.
