Final Exam

ACS 2nd Sem

 

 

Exams: Exam dates are set to provide regular and systematic assessment – exam content will be limited to that content prior to the class session prior to the exam.  Each student is advised to bring a personal calculation aid with them to every class, laboratory and test/examination (abacus, slide rule or calculator) - these cannot be shared during tests and should be capable of manipulating scientific notation, logarithms and exponents.  Only NON-PROGRAMMABLE SCIENTIFIC CALCULATORS may be used during tests, quizzes and examinations.  My philosophy regarding the memorization of formula and physical constants is that each student can and will learn those that they find useful and valuable on an ongoing basis.  Therefore I, for this semester only, (don’t count on anyone else doing this) will allow the use during quizzes, tests and exams the use, in addition to your personal calculator, pencil, and blank scratch paper, the use of one and only one 3”x5” conventional index card.  No card may be used on the course final – you must work toward full independence by the end of the course.  This one card may contain any physical constants, formulas, sample calculations, prayers and/or meditative verse that you believe you may find useful.  All information on the card must be handwritten.  I will provide unusual or unique physical constants for specific chemicals, bond energies, activities of metals, and standard molar enthalpies, etc.  Each student may possess one and only one card as described above, violations of this rule are considered academic dishonesty - severe penalties will be enforced.   It is vital that you report promptly for exams, as no time extensions are possible. 

 

Homework:  Success in General Chemistry is undeniably linked to the amount of time invested in learning the material and problem solving.  In order to facilitate your mastery of chemical problem solving this course will use the eGrade EduGen Homework – continued from the first semester, for the assignment of graded homework.  Additional review material and practice exam are available from the WebCT site.

 

Writing Assignment: Go to the library and browse the stacks of paper chemistry periodicals.  Start with a journal like the Journal of Chemical Education (JCE).  In JCE you will find easy reading in the front, and research papers in the back.  In a journal like “Analytical Chemistry” you will find some “review” articles in the front and research articles in the back.  Your assignment is to photocopy a research or review article of your choice and write a review of the paper.  Summarize what they did (or the development of some field of chemical knowledge), specifically how they made their measurements/synthesis/experimentation, and what it all means or how it relates to general chemistry topics.   You will turn in the copy of the original article and your review together on April 4, 2006.  The journal must have chemistry in the title, the article selected must be either review or research, not a demonstration, news item or otherwise ‘easy reading.  If in doubt- ask!

Your review will be graded based on both content and format, spelling and grammar “count”.   The paper will be counted in the final grade at a weight somewhat equivalent to a tests.  You may include the words written by others directly only when presented in quotation marks and properly cited.  You may include the facts and ideas of others in any format only when you properly cite the source.  You may include your own original work without restriction (For example: this assignment was based on an article written by Dr. David Newman at Bowling Green State University (http://www.bgsu.edu/departments/english/rcweb/chem.htm))

The Fine Print:

The LSSU Catalog/Calendar contains a more complete description of your rights and responsibilities as a member of the University community. In the Catalog/Calendar you will find a complete statement of our institutional purpose, definitions of university terminology, our Equal Opportunity policy, and especially the ACADEMIC POLICIES.  Attendance: I expect you to attend and participate in class as a valuable and contributing member in the community of learners of which the course is comprised.  Not every contingency leading to an excusable absence can be anticipated, and an occasional absence may reasonably be anticipated which requires special consideration.  However, extended absences, even for valid reasons, preclude the student’s full and active participation in the course, in meeting the full objectives of the course and may lead to a non-passing or incomplete grade – even when other work is completed satisfactorily. NOTICE:  A failing grade (F) can be assigned to students who commit acts of academic dishonesty. At the instructor’s discretion this grade may be for the assignment or the entire course depending on the nature and severity of the offense.  Academic dishonesty includes but is not limited to cheating (the intentional use or attempted use of unauthorized materials, information or study aids in any academic exercise) , fabricating (intentional or unauthorized falsification or invention of any information or citation in an academic exercise), facilitating academic dishonesty (Intentionally or knowingly helping or attempting to help another violate any provisions of this code), or plagiarism (intentionally or knowingly representing the words or ideas of another as one’s own in any academic exercise).  Definitions from the Code of Academic Integrity, University of Maryland at College Park.  This syllabus is not intended to be a comprehensive statement, please be aware that other academic policies and procedures are outlined in the catalog and they apply to you as well. The course syllabus represents the best estimate and projection of course content, scope and sequence. In the case of extenuating circumstances, changes in enrollment, flood, fire or tornado, other Acts of God, by mutual consent, or at the discretion of the instructor, the course and lab syllabi are subject to change.  Americans with Disabilities Act: In compliance with Lake Superior State University policy and equal access laws, disability-related accommodations or services are available.  Students who desire such services are to meet with the professor in a timely manner, preferably the first week of class, to discuss their disability-related needs.  Students will not receive services until they register with the Resource Center for Students with Disabilities (RCSD).  Proper registration will enable the RCSD to verify the disability and determine reasonable academic accommodations.  RCSD is located in the Library, extension 2454.

 


Laboratory:  Chemistry is an experimental science.  You are encouraged to think independently about the data you collect and you will not be graded solely on whether you acquire the right number or deduce the correct explanation, but rather whether your explanations and hypotheses follow logically from the data and that your reasoning is clearly stated.  In the laboratory component of this course students may OCCASIONALLY work together in teams of no more than two, as directed by the instructor.  Each student team member is responsible for assuming an equal share of the lab responsibilities and work load.  Students are to prepare the pre-laboratory assignments before coming to lab, and to complete and turn in their own laboratory reports as assigned.  Students are advised to read the laboratory procedures and carefully plan their work to maximize efficiency and guarantee success.  If you must be absent from a laboratory session you should contact your laboratory instructor and attend one of the other sessions that has available space within the next week.  Missed labs cannot be made up after the end of the week following the scheduled lab.

Safety in the Laboratory

While working in the laboratory you are expected to comply with the safety rules which follow, any and all rules posted in the laboratory or as established by your instructor.  Violations of the safety rules endanger both you and others in the laboratory.  Students who violate the established rules and procedures may be subject to warnings, reductions in grade, or expulsion from the lab.  Safety rule violations include but are not limited to the following. (Consult your laboratory instructor for specific directions regarding the laboratory activities each week and for specific information regarding the hazards and precautions required in each laboratory session.)

1.         What is not explicitly allowed in the lab – it is FORBIDDEN! Always ask your instructor prior to engage to any not described in your lab book activity.

2.         Not wearing appropriate safety goggles for the activities assigned.  NOTE: some activities such as pouring and mixing concentrated reagents require the use of SPECIAL chemical splash goggles and perhaps other personal protective equipment.  Consult your instructor and always use the highest level of protection available and appropriate for the task assigned.

3.         Smoking, eating, or drinking in the laboratory.

4.         Pipetting by mouth or otherwise handling chemicals unsafely. Using an open flame to heat flammable liquids.

5.         Not working under a fume hood when directed to do so.

6.         Failing to report or clean up chemical spills or broken equipment.  Special spill kits are available in the lab to handle a variety of spilled chemicals.

7.         Disposing of chemicals improperly.  ALWAYS consult the instructor for the proper handling instructions or location of the designated "USED CHEMICALS" container for the experiment.

8.         Working alone in the laboratory or working outside the regularly scheduled lab times without permission. 

9.         Performing unauthorized experiments.

10.     Engaging in horseplay or other behavior that jeopardizes your safety or that of others in the laboratory.
