INSTRUCTOR’S OFFICE AND AAC HOURS: 

The best times to see me if you need help from me are during lab times. Unofficial office times include whenever my office is open. The details of my schedule may be found at this link: http://www.abac.edu/wp-content/uploads/2013/01/ScheduleSm142.htm

 

ATTENDANCE POLICY

You are required to attend all labs. By school regulation, instructors will keep accurate attendance records and must report the number of absences for each student when midterm and final grades are turned in. Two tardiness instances will be equated to one absence. 2% of the class grade will be attributed to attendance. Points will be deducted from the attendance grade proportionally to the number of documented unjustified days of absence. Unjustified absence for a time equivalent to two or more weeks of class will result in forfeiture of the attendance grade. To avoid penalty, any absence will have to be justified beforehand or immediately after it has happened.

 

A student who does not show up in a lab cannot be included in the corresponding lab report and therefore receives a grade of zero for that lab. Points will be deducted for tardiness proportionally to the amount of time missed. Showing up after the end of lab manipulations will be equated to an absence.

 

A student who serves as an official representative of the college will not be penalized with unexcused absences when the absences result from regularly scheduled activities in which he/she represents the college.

 

Regardless of the cause of the absence, it is the responsibility of the student to contact the instructor prior to the absence and to make arrangements to make up any work that will be missed, in a manner acceptable to the instructor.

COURSE DESCRIPTION, PRE/CO-REQUISITES, TOPICS, AND OBJECTIVES

This course serves as the laboratory companion of CHEM 1212 lecture. Admission in CHEM  1212L   requires passing CHEM 1211L with a grade of C or better. The student must show proof of satisfaction of that requirement in order to be allowed to stay in the course. Upon request, you must show proof that you fulfill the pre-requisites to be in this class. In order to do that, turn in a printout of your transcript highlighting the part that shows that you satisfy the conditions to be in the class.

 

CHEM 1212L must be taken simultaneously with the corresponding lecture: CHEM 1212. Any departure from this rule must be authorized by the Head of the Science Department.

 

Chemistry 1212L (1 credit hour) meets twice a week for three hours. General topics include Freezing point depression, Reaction kinetics and equilibria, Acid-base reactions, Thermodynamics and Electrochemistry.

 

Chemistry 1212L appears together with 1212 in either Area D (Science, Mathematics, & Technology) or F (Major-Specific Courses) of your core curriculum. In Area D, the 1211/L-1212 /L sequence may be used to meet the lab science sequence requirement for science majors. Non-science majors may use both 1211/L and 1212/L in Area D or may take only 1211/L and apply it in Area D as one of the lab science courses.

 

Objectives for this lab include hands-on activities designed, both quantitatively and qualitatively, to illustrate the various concepts uncovered in the lecture component. This course is designed to train students in laboratory techniques that are essential to understanding the chemistry concepts uncovered in CHEM 1212 lecture. Emphasis will be placed on laboratory techniques and experimental data collection, processing, analysis and interpretation. Critical thinking, computational and problem solving skills as well as drawing or diagramming will also be addressed. Topics uncovered include Freezing Point Depression, Kinetics, Chemical Equilibria, Acid-Base Reactions, Thermodynamics, Redox Reactions and Electrochemistry.

 

REQUIRED MATERIAL:

 

SCHEDULED ACTIVITIES

The laboratory work will include pre-labs, lab quizzes, laboratory experiments and reports, a lab mid-term, and final exam. The lab final will be completely comprehensive, covering topics contained in all labs.

 

Pre-Lab Activities and Quizzes

Pre-labs and quizzes will be done together. They will be done mostly online on D2L. They are designed to help students gain familiarity with the concepts underlying the experiments to be conducted as well as the various techniques and procedures involved in those experiments. You will be allowed to make as many attemps as you want to get as high a grade as you wish before the deadline. Pre-labs and quizzes are to be completed before coming to the laboratory. Printouts of the Otherwise a zero point grade on the relevant activity will result. 

 

Post-Lab Reports

Each lab performed is the subject of a report. The lab work will be done in teams. However the lab reports will be individual and will be done on D2L. Lab reports will be due two days after the lab was conducted. Late labs will receive a grade of zero.

 

TESTS.

There will be one lab mid-term and one lab final tests. Both tests will have equal weights.

The material covered by the mid-term will include the pre-labs, quizzes and labs performed up to that time. The lab final test will cover all lab-related activities (pre-labs, lab quizzes, experiments) performed during the term.  

 

Students enrolled in classes in the Division of Science and Mathematics will be expected to demonstrate an understanding of subject matter requiring higher order processing skills. The tests will seek to assess students’ ability to understand the concepts which govern the experiments run in the lab, as well as the data processing and interpretation, and problem-solving skills gained. Each test will be made of two components: in-lab and online.

 

In-lab test questions will be a combination of multiple choice and essay types. Instead of a mere statement of facts, a typical multiple choice question will also include the justification of the statement. This not only better demonstrates knowledge of the material, but it also limits to a minimum the probability of obtaining a high grade through picking the correct answer by mere luck.

 

Even though they take a considerable amount of time to grade, essay questions provide better insight into student knowledge and thinking process, which allows for better intervention to improve student knowledge quality and level when such intervention is warranted. Typical essay questions will seek to evaluate the ability of the student to explain, interpret, and/or apply concepts.

 

Questions in the online test components will be mostly calculations, in addition to short answers, matching and fill-in-the-blank types. The main objective of the online components will be the assessment of students’ problem solving and experimental data processing skills.

 

Rather than rote memorization, the correct answers to the questions will combine knowledge and explanation of concepts, and /or ability to rationalize phenomena and procedures, which are better tools to assess mastery of concepts and problem solving procedures. 

 

Only compelling and verifiable reasons will be accepted in order to make up a missed midterm test. The explanation for missing a test must be given prior to the test, except for situations out of the student’s control. Pre-approved missed mid-terms will be made up at final test time. Failure to secure a permission for make-up before the test will result in a zero for the missed test. No make-ups will be allowed for the final test.

 

EVALUATION.

The laboratory grade will be determined from the evaluation of pre-labs, lab quizzes, laboratory reports, lab mid-term, and lab final exam. 

 

The average grade from pre-labs and quizzes will count as one lab test on your final lab grade. The average grade from the lab reports will also have the weight of one lab test. The mid-term and the final exam will be the other major components. 2% of the lab grade will be reserved to the conduct in lab. Students will be evaluated also based on the way they follow the lab rules. 2 points will be deducted from the grade at every violation citation. 

 

The lab grade will be made of the following items:

1.      Pre-labs & Quizzes = one test

2.      Lab Reports = one test

3.      Mid-term test

4.      Final test.

Overall: 4 performance items, each carrying 24% of the total lab grade.

5.      Attendance and Conduct: 4% of total lab grade

Total %: 100%

 

Grading Scale & Percentage/grade conversion

Percentage       Grade

90-100 %         A

80-89               B

70-79               C

60-69               D

0-59                 F

 

LOWER MIDTERM  GRADES

If the grade of the final test is higher than the mid term grade, the mid term grade may be dropped, at the discretion of the instructor and if the conduct of the student justifies it. However the grade to be dropped must be in a position to affect the letter grade of the lab in order to justify its removal.  Moreover the grade to be dropped must correspond to a test that was actually taken. A skipped test does not apply.

 

ACCOMMODATIONS FOR STUDENTS WITH LEARNING DISABILITIES

Special accommodations will be provided for students with learning disabilities on a case-by-case basis. Any student who fulfills learning disabilities conditions must get in touch with the teacher in order to insure his/her case will be dealt with properly and in a timely manner.

 

WITHDRAWAL FROM THE COURSE

If the student needs to withdraw from this course, it should be done by the deadline date of June 26, 2014. Dropping out of the lab leads to dropping out of the class and vice-versa. If the course is dropped by the deadline date, the student will be awarded a grade of W. After the withdrawal date, dropping the lab leads to a grade of WF. The course can be dropped with a grade of “W” only under very extenuating circumstances. In this case, the withdrawal must be approved by the instructor and the Chair of the Science Department. Otherwise, a grade of “WF” will be awarded. 

 

CHEM 1212L is a co-requisite of CHEM 1212. Dropping one leads to dropping the other.

 

More information on this and other issues may be found in the current ABAC catalog accessible at the following link: http://www.abac.edu/wp-content/uploads/2012/11/catalog_2013_141.pdf

 

 

It is important to notice that even when it is done by the deadline, dropping classes may have negative effects on such processes as Hope scholarship (which considers attempted instead of completed hours) or insurance (some companies require full time status for coverage).

 

ACADEMIC DISHONESTY:

Academic dishonesty as defined in the Abraham Baldwin Catalog will not be tolerated. Cheating, plagiarism or any other form of dishonesty is strictly prohibited.  Sanctions will be imposed on anybody caught in the act. The source and the beneficiary will be punished equally. Depending on the gravity and / or frequency of misconduct, the punishment could amount to failure in and dismissal from the class.  All infractions will be dealt with according to the procedures outlined in the Catalog. Sanctions may include a zero on the assignment or even failure in the class. Students are recommended to read and review this material.

ELECTRONIC COMMUNICATION DEVICES POLICY

The use of any device which can deliver and/or receive electronic messages will be strictly prohibited. The source and the destination of the messages will be sanctioned equally.

 

EYE AND HAND PROTECTION:

Students are required to wear eye and hand protection at all times in the laboratory. Students not wearing goggles and gloves in the lab will be asked to leave and no credit will be given for that particular experiment. In requiring that students wear goggles and gloves, the need for safety in the lab outweighs the need for comfort.

 

General Safety and Laboratory Rules:

1. Be familiar with laboratory procedures and safety precautions to be carried out before coming to lab. If you are at all in doubt as to any procedures or safety measures, consult with your instructor.

2. Be aware of what is happening around you at all times.

3. Use common sense at all times when in the lab.

4. Listen very carefully to any safety procedures and cautionary measures discussed by your instructor. Ask questions if you still are uncertain of any safety procedures and cautionary

measures.

5. Wear older, less valuable clothing (preferably cotton or wool) if possible. If you must wear nicer clothing, wear a lab safety coat. Some safety coats will be made available in the lab.

6. Never eat or drink in the lab.

7. Wash your hands immediately after contact with any lab chemicals. Always wash your hands before leaving the lab.

8. Wear closed, leather shoes and long pants or skirts (something to protect your legs).

9. Don't wear eye contacts in lab if at all possible.

10. Tie up long hair.

11. Help look after your lab partner and others around you.

12. Exercise special care whenever you are using flammable chemicals.

13. Never perform unauthorized experiments.

14. Learn the location of the eyewash stations and safety shower.

15. THINK SAFETY AT ALL TIMES.

 

LEAVING THE LABORATORY:

See number 7 under General Safety and Lab Rules. Clean up your area before leaving. Points will be taken off for leaving the work place dirty.

 

MISSED LABS.

A missed lab can't be made up after the week when it was on schedule. A valid reason for missing the scheduled lab must be given and accepted before a student can make up a lab in section other than the one in which he/she is registered. It is the responsibility of the student to contact the instructor prior to the absence and to make arrangements to make up any work that will be missed, in a manner acceptable to the instructor. Any missed lab work that is not made up will receive the grade of zero.
