 Prelab and Laboratory Reports Policy

1. Prelab questions should be submitted at the beginning of each lab section
2. Prelab and lab reports turned in late will be graded at a rate of 10 % per day late

    (you will lost 10 points per day late)

3. Lab report will include data collected in the lab showing calculations, and the post

    lab questions  in neatly hand writing or word processor, each student should submit his/her

    prelab and lab report making sure of writing his/her name and signature.

  4. Questions about homework or questions related to grading will be discussed during office

     hours. If you can not see the instructor at the office hours cited above, you can email or call

     to make an appointment that suit your schedule.

 

Lab Procedure and Pre-Lab:

It is mandatory to read carefully the procedure before coming to the lab. You should be able to identify the major steps of your experimental procedure and briefly to write it down in your notebook. Now write the answers to the prelab questions using very clear hand writing. To answer these questions make use of the material discussed in class, material in your lab textbook, use external sources, FSU-library and Internet. Your notebook will be checked out before the starting of the experiment, you will lose points in your final score if you do not comply with the appropriate notebook record keeping (see Grades section).

 In your notebook you should have:

1. In the first page your complete full name, Chemistry lab section, addreess,

     phone number or email.

2. Pages after the first one should be numerated and should contain tiltle and

     experiment number,objective, summary of the procedure indicating

     the most important steps of the experiment

3. Prelab questions and answers
4. Data section
5. Calculations
6. Conclusions

Submit: Summary of Procedure, Prelab Questions and Answers

An excellent example of a good record keeping is given in the appendix A of your laboratory textbook, check this appendix to familiarize yourself with this important scientific practice. Follow this example also to write your lab reports. Check the model notebook provided by the instructor.

 

1. Experimental Laboratory Section

Before coming to the lab make sure that you have read and understood the procedure for the experiment that you will be doing. Then proceed to answer the prelab questions, always thinking why a particular question is being asked. This is important because allow not only to understand better the experimental procedure, but also because facilitate the interpretation of the data that will be collected during the experiment. To properly work in an amenable and safe environment very basic simple precaution measurements should be followed at all times in the chemistry laboratory.

1. Make sure you understand all the safety precaution measurements

      discussed the first day of class. If you have doubts read the laboratory safety

      instructions in your laboratory text or consult your instructor.

2. You must arrive on time and turn in the prelab questions with the respective

      answers before the beginning of the experiment.

3. Be aware that bringing food and eating the food in the lab is

       ABSOLUTELY FORBIDDEN, the food could easily get contaminated with the

       fumes or vapors of some volatile chemicals.

4. Remember that SMOKING is absolutely forbidden in any lab, this policy specially

      applies to the general chemistry laboratory.

5. You must wear safety goggles at all times during the experiment, this will allow you

      to avoid eye related injuries. The Department of Chemistry and Physics is not longer

       providing safety goggles. Each student is responsible for bringing his/her own goggles

        (available in the bookstore) to the chemistry laboratory. The use of safety goggles is a

       requirement that will not be waved, you will not be allowed into lab without the

       proper protecting goggles.

6. Avoid carrying out any unauthorized mixing of chemicals, always consult your

      instructor first.

7. Try to organize your work area, as this will prevent the occurrence of unwanted

       mistakes that could harm your experiment. When you finish clean yourself and your

       work area before leaving the lab.

 

1. Laboratory Report

-Short Report (SR): In this report you should provide the data collected, sample calculations, results, and the post lab question answers. This can be acomplished just filling the blanks for each experiment in your laboratory manual. All your answers should be neatly written to make sure that the instructor understands your solutions (not credit will be given for confusing, unreadable work). I advise you to work out your answers first, then do all the necessary editing as you do when you write a paper. This process will allow you to eliminate any errors and to deliver a more professional work.  If there are mathematical equations involved, define each variable first, then show the operations indicating units and report your answer with the proper units and the correct number of significant figures.

When you done clip the pages together and submit your short report making sure that your name is in every page submitted.

 

-Long Report (LR): Prepare a formal written report using a clear hand writing data sheet from the experimental section. Your report should have the experiment title, objectives, abstract, introduction, summarized procedure and a brief description of your results that include sample calculations, discussion, conclusions, and references. You should submit with your report the answers to the post lab questions using a typewriter or a word processor. Check the model report and directions provided in Canvas. https://adfs3.uncfsu.edu/

1. Due Date Assignments Policy:

The final due date for any assignment (exams, lab reports, prelabs and note books) is by 5:00 PM of the day of the final exam date. After this date no assignments will be accepted.

 

1. Make up Examination Policy:

There will be no make up examinations and make up labs except in the case of serious illness or accident (properly documented), family emergency, or participation in University official activities (class field trips, etc.). For the latter case, make up-examination arrangements must be made in advance.

 

1. Student Behavioral Expectations:
2. Students are expected to arrive to class on time, remain in class until dismissed by

the instructor, and refrain from preparing to leave class until it is dismissed.

2. Students should avoid passing notes or carrying on private conversations while class

is being conducted.

3. Students should avoid the use profanity in the classroom.
4. Any form of cheating is considered an academic dishonesty or misconduct and will

be punished. For information about disciplinary measures and university policies for

academic misconduct, read the Fayetteville State University Student Handbook.

5. Students should avoid the use of cell phones during exams and class time, this affects the concentration and distract your peers.

 

1. Consequences For Failing to Meet Behavioral Expectations:

With first time violation of one of the rules above, he or she will be warn privately by the instructor after or before next class. Second time violations will be punished by deducting as many as twenty points from the student's next exam grade. With third time violations, the student will be reported to the Dean of Students for disciplinary action according to the FSU Code of Student Conduct.

 

1. Health Concerns Policy:

Students in this chemistry laboratory course should be aware that a wide range of chemical substances are used. If a student has or suspects that a medical condition or health problem exists or may come to exist and he or she might be affected by being in a chemical laboratory (e.g., chemical sensitivities, fainting, pregnancy, etc), the student should consult his or her personal physician. The student may also wish to consult the University Health Care Unit. Your laboratory instructor cannot give you health care advice, but should be informed appropriately of the student's concerns and potential problems.

 

1. Academic Integrity Statement: One of the fundamental pillars of the university is the academic and personal integrity of all its members. You must be truthful and honest at all times and must be aware of what kind of situations and activities constitute ethical violations. In this class the following activities or situations will be considered violations of the ethical code and will be punished accordingly: cheating on exams, plagiarism (misrepresentation of materials obtained from the Internet or from other sources), lying, helping someone else to cheat, reuse of assignments, unauthorized collaboration, alteration of graded assignments, forgery, falsification and unfair competition. Please, report any violation to the instructor. Unauthorized cheating is not limited only to those enumerated above, for a more complete list you are advised to consult the Fayetteville State University Student Handbook at http://www.uncfsu.edu/handbook.

Any form of cheating is considered as an academic dishonesty. Cheating in this class will be punished with an F for the exam or in any other assignment where the cheating is discovered. The use of programmable calculators is strictly forbidden during exams and quizzes, try to bring a simple no programmable calculator if you need one during the exam. Avoid the use of cell phones during the exam and class time, this affects the concentration and distract your peers.

 

1. Revision of Grades - Students Responsibilities

Absences from class will be handled following strictly the University policy. Absences of more than 10 % of the total contact hours the course meets during the semester, which is approximately seven (7) total hours of unexcused absences will fall in the category of ”EXCESSIVE ABSENCES-EA”. As indicated in the new guidelines, “WN” grade has been eliminated and it is the STUDENT'S RESPONSIBILITY TO WITHDRAW HIMSELF OR HERSELF FROM THE CLASS. Please, check the 'Revision of Grades-Student Responsibilities' at: http://www.uncfsu.edu/fsuretension/policiesprocedures.htm.  “X” GRADE (NO SHOW): will be assigned to any student on the roster that did not attend during the first week of classes or, in online classes, did not interact with class website during the first week of classes. Since X grade is not a final grade, it can be removed if the student begins attending class. “EA” GRADE (EXCESSIVE ABSENCES): will be assigned to students whose absences exceed 10 % of class contact hours. After the grade has been assigned the student will be warranted in order for them to take the corrective action.

NEW FINAL GRADE: “FN” (FAILURE DUE TO NON-ATTENDANCE )- Final grade for students who are on class roster, but never attend the class. An FN grade is equivalent to an F grade in the calculation of the GPA. For more information about this issue you should check:

http://www.uncfsu.edu/fsuretention/policiesprocedures.htm

 

VIII. Academic Support Resources:

The instructor will try to make available any additional material that will be required for the proper instruction of students, through the canvas website (https://adfs3.uncfsu.edu/), and the instructor web site (http://faculty.uncfsu.edu/jcastill/).
