Objectives: Consistent with the goals of the UNCP General Education Program (see p. 23 of the UNCP catalog), the activities associated with this course are designed to provide students an understanding of the fundamental principles of chemistry and to foster the ability to quantitatively analyze data, to write and speak clearly, and to think critically and creatively.
Lab safety: Students must follow all written and verbal instructions regarding safe lab procedures. A written copy of lab safety policies will be provided. Failure to comply with these rules may result in dismissal from the lab. Eye protection must be worn at all times in the lab.
Description: This lab will
try to reinforce the concepts presented during the lecture about: composition,
structure, and properties of matter, including stoichiometry,
atomic and molecular structure and theory, and chemical periodicity.
Format: Each lab will start with a lecture that will describe the experiment. After the lecture the students will start the experiments under the supervision of the instructor. Because of the importance of the safety in chemistry, students should bring scientific calculators , lab coat and appropriate safety eyewear. Each student it is responsible of cleaning to work space in lab. Failure to do so will result in a 10% penalty of the lab report grade.
Any student with a documented learning, physical, chronic health, psychological, visual or hearing disability needing academic adjustments is requested to speak directly to Disability Support Services and the instructor, as early in the semester (preferably within the first week) as possible. All discussions will remain confidential. Please contact Disability Support Services, DF Lowry Building, Room 103 or call 910-521-6695.
While exposure to chemicals commonly
encountered in a university laboratory setting pose no or low risk to an adult,
they can pose a significantly higher level of hazard to a fetus. Many of these
hazards are not well studied, and it is not known what exposure level is safe
for a fetus. It is therefore prudent for pregnant women to limit the
unnecessary exposure of a fetus to any chemicals. This is especially true if
the chemicals are mutagenic (causes damage to chromosomes) or teratogenic (causes birth defects and/or fetal death).
If you have recently become pregnant or
anticipating becoming pregnant while you are enrolled in a laboratory course, please
inform your laboratory instructor and s/he will provide, upon request, the
Material Safety Data Sheets for the chemicals you will be exposed to during
this course. You can then discuss with your physician the potential hazards
these chemicals pose to the fetus in order to make a choice as to whether or
not to stay enrolled in the laboratory course during your pregnancy.
Course Requirements: Graded assignments for this course will include the lab reports, one midterm test and a comprehensive final exam. Pertinent questions and problems will frequently be suggested for work outside of class, though submission of these assignments is not required.
Evaluation/Grading: Course grades will be computed on a 4-point scale based on evaluation of a laboratory notebook (10%), 9 written lab reports (60%), a midterm test (15%) and a final examination (15%). All lab reports are due the next week following the experiment. For each day of delay you lose 10% of the grade. Now lab report will be do after 10 days. The Last lab report will be due before the final test. No lab report will be accepted after the final test.
Letter grades for the course will be assigned
according to the scale described in the University catalog (see the relevant
section of Academic Procedures and Policies").
Attendance: Attendance at all scheduled lab
sessions is required. There will be no make up labs. If absence is unavoidable,
excuses must be written and submitted one week prior to or following the
absence. Additional documentation may be required. Unavoidable absences are
considered for personal or immediate family illness, death in the immediate
family, or business commitments that are verified by your employer in writing.
Missed labs that do not meet the above criteria will result in a grade of “0”. No
student will receive credit for the lab if he or she misses in excess of two
lab periods. For religious holiday policy please refer to the following website
for details: http://www.uncp.edu/chem_phy/religiousholidaypolicy.pdf.
Honor
Code: Students are
expected to follow the UNCP Honor Code (see pp. 49-51 of the UNCP catalog); settled cases involving first-offense
violation of the Honor Code will result in a minimum penalty of course
failure.
Good Communication: It is the best way to avoid problems and misunderstandings. Please discuss any questions or concerns you may have about this course or general policies with me.
