+ Attendance is required as part of the lab grade. You must be present 2.5 hours to receive 30 points credit toward your lab score. A 40 point (30 minute) quiz will be given at the end of the period which is a separate score (not part of the lab score).

pg. 3

Student Responsibility: Each student receives this information in the first lecture section. It is your responsibility to read this material and be familiar with the course content, procedures, and grading. You are also

responsible for any announcements concerning course procedures which are made in class, whether you are

present or not! If you are absent, you are expected to get notes, announcements, etc. from another student in the

class. Any questions about grading of a lab report, quiz or exam must be made within 1 week of the receipt

of said result.

Grading: Your performance in the course will be evaluated on the basis of total points earned for the entire semester. There is NO extra credit. The distribution of points is as follows:

Quizzes 120

Laboratory 200 A minimum of 50% of the total lab points are required to pass the course.

Midterm I 120

Midterm II 120

Midterm III 120

Final 320

Total 1000 pts

Mandatory Quizzes: There are two mandatory quizzes to be taken on Carmen. https://carmen.osu.edu. One quiz deals with Academic Misconduct and the other with the Syllabus. Unless you receive perfect scores on both quizzes, you will not receive a passing grade in this course (an E will be submitted as your final grade). You MUST complete the quizzes before the end of the second week of the semester (Friday, January 22, 2016).

Quizzes: These will be given in labs in the weeks indicated on the Schedule of Assignments (Rev. period, see page 2). There are NO make-up quizzes. ALWAYS SHOW YOUR WORK ON QUIZZES to receive full credit. Bring your approved calculator to quizzes and exams. Calculator covers must be removed and put away.

Midterm Exams: These exams are given at the times shown on the Schedule of Assignments, (page 2). Make-up exams will be given only in the last week of regularly scheduled classes for medical reasons (documented) or a preapproved university conflict. Exams are a scheduled part of this course and attendance is required (exam location is based on lab section). Students with University conflicts should consult the lecturer. Computer answer sheets from exams will not be returned. Answers will be posted. An approved calculator must be used or you take the exam/quiz without a calculator. Calculator covers must be removed and put away.

Final Exam: The final exam must be taken at the University scheduled time. OSU ID cards will be collected at the final exam. Final exams will not be returned. You can NOT keep any part of the final or copy your answers to take with you (doing so is academic misconduct).

NO HEAD COVERINGS ARE TO BE WORN DURING QUIZZES OR EXAMS!!! (If you wear a head covering for documented religious or medical reasons, please see Dr. Zellmer before the quizzes or exams.)

NO FOOD OR DRINKS DURING QUIZZES OR EXAMS!!! (If you may need these for documented medical reasons, please see Dr. Zellmer before the quizzes or exams.)

NO ELECTRONICS OTHER THAN AN ALLOWED CALCULATOR DURING QUIZZES OR EXAMS (they must be turned off and put away. The only things on your desk should be an allowed calc. w/o the cover, a pencil and maybe an eraser.)

LABORATORY: Consists of one 2 hour and 55 minute session per week; YOU MAY WORK IN THE LABORATORY ONLY DURING YOUR SCHEDULED LABORATORY PERIOD! Any time remaining in a lab period and the last lab (checkout) period can be used to complete a previous experiment - discuss this with your TA first (see report due dates on page 4). Read the experiment before you come to lab so that you come prepared to work efficiently and carefully. A minimum of 50% of the total lab points are necessary for a passing grade in the course.

pg. 4

LABORATORY NOTEBOOKS: Will be graded. You are required to use the Student Lab Notebook, and record all entries in ink. Record procedures followed (in your own words), observations made and data collected, calculations and results only in the notebook (nothing should be written in the manual or other pieces of paper). The notebook should be sufficiently neat and organized so that another person can follow what you did. At the end of each lab, you AND your TA MUST sign and date your data pages and you submit the copies to your lab instructor in order to receive credit for the lab. Your lab notebook sheets must be signed by your lab instructor before leaving the lab in order to receive credit for the lab. See Appendix A of the lab manual and the links on pages 8-10 of the syllabus for further information about the notebook.

LABORATORY REPORTS: Due at the beginning of the lab session ONE week after the completion of the experiment. Any report submitted thereafter (even if on the same day) will be penalized 10% per day. If you submit a late report to 110 Celeste Lab, you must notify your TA by email within 1 day after submission. NO credit will be given after 2 weeks or past the due dates shown below. If you need to miss lab for a pre-scheduled reason (e.g. doctors appt., family matters, etc.) the report must be turned in before leaving (prior to your lab period) or the report will be considered late. Lab reports should be graded by your lab instructor and returned one week after submission (let me know if its been more than one week). Details for the lab report expectations are included in Appendix B of the lab manual and on pages 8 and 9 of this syllabus. You are expected to print out the grading rubric (posted on Carmen) and attach it as the last page for the report. The lab score will be factored to 200 points. Photocopies of reports are not permitted - it is illegal to photocopy the lab manual.

Lab Reports for Expts. 1-12 will not be accepted later than 4:30 PM, Fri., March. 11 (In 110 Celeste) No Lab Reports will be accepted after 4:30 PM, Mon., Apr. 25 (In 110 Celeste)

Laboratory Safety Requirements: Students are required to read, understand, and implement the safety precautions indicated in the laboratory manual and laboratory handouts. The precautions are summarized on a safety form which must be signed by all students during their first laboratory period. The following are selected instructions from the safety form:

1. You must wear Department-authorized ANSI code goggles in the laboratory. Goggles will be issued during check-in. After the first free pair, goggles may be borrowed, if available, from CE 231 or 331; otherwise, they must be purchased from CE 180. Not wearing goggles will result in the loss of 10% of the grade for the experiment. For any subsequent violation, an additional loss of 10% of the grade will result. Continued violations may result in dismissal from the course. The wearing of contact lenses is NOT recommended.

2. Each student must wear adequate clothing to reduce the possibility of injury from chemicals or broken glass. Students who wear sandals, shorts or short skirts will be sent home NO make -up time will be provided. Pants long enough to cover the ankles must be worn.

3. Familiarize yourself with the location of the fire blanket, fire extinguisher, and eye wash in the laboratory.

4. Promptly report all accidents, no matter how small, to your lab instructor.

5. Your work area should be cleaned before you leave lab. After putting your equipment away, wipe down your work area with a wet sponge or towel. This ensures that you, and other students who use the space, will not be harmed by chemicals left on the desktop. Also, clean up spills in the balance room by brushing chemicals into a weighing dish.

6. No unauthorized experiments are allowed. No chemicals may be removed from the lab.

7. Lab Policies and Procedures READ THIS

Laboratory Video Instruction: Laboratory videos are shown at the start of the laboratory. Students must view the entire video prior to starting the experiment. Students who are late for laboratory will have to view the video on the computers in the Learning Resource Center 170 CE (or the lab itself when possible). You will need to print a form, or obtain one from a TA there, to be given to your TA in lab. (This requires your BuckID)

The videos are designed to supplement the instructions in the laboratory manual. Students will be better prepared to assimilate the video instructions if they have read the laboratory manual prior to the laboratory.

The videos are short and there is insufficient time to take detailed notes if you are not already familiar with the experiment. You are encouraged to view the tapes at your own pace either before or after laboratory (go to http://app.chemistry.ohio-state.edu/chemflashplayer/ ). Its useful to do this before writing your procedure in the lab notebook. However, you are still required to view the videos at the normal laboratory time.

Requirements in this syllabus (assignments, due dates, etc.) may

ONLY be altered by Dr. Zellmer (lecturer and lab supervisor)

pg. 5

Medical Insurance Coverage: Due to the potentially dangerous nature of laboratory work, you are reminded to maintain medical insurance coverage through OSU health service or a private agency when enrolling in Chemistry laboratory courses. You are responsible for any medical costs associated with an injury in lab.

Homework: Assignments are posted on-line on the course web page (not Carmen). These are the End-of-Chapter Exercises which I feel you need to be able to do or you will not learn the material and will not do well on quizzes and exams. These homework assignments will not be graded. However, doing ALL assigned problems is often the best way to determine how well you understand the material. Homework solutions may be posted on line on our course web page and Carmen. The publishers solution manual (for the 10th, 11th, 12th and 13th editions) containing worked-out solutions for every EOC problem are posted on Carmen (see Content tab). Use them to check your answers after doing each problem (do not do a whole bunch before checking to see if youre doing them correctly).

Lecture Notes: Available on the course web page (not Carmen). I would suggest printing them and bringing them to lecture. It will make it easier for you to keep up. See course web pages and Carmen for additions or corrections. These are PDF files so you can use a tablet computer which, with the proper app, would allow you to write on them and record the lecture, a very useful feature (more useful than Angry Birds).

Office Hours: I will be available in my office, 280B Celeste Lab, M, W, F 1:30 - 2:30 PM and T, R 10:00 - 11:30 AM. You can also make an appointment for other times or stop by any time. I will be around

pretty much every day of the week.

Additional Assistance: 1. Lab Supervisor - Dr. Zellmer (zellmer.1@osu.edu, 280B CE, 292-2149) will help with lab problems.

2. You are strongly encouraged to make use of the Learning Resource Center (170 CE) frequently.

3. Undergraduate chemistry web site: https://web.chemistry.ohio-state.edu/undergraduate

Learning Resource Center (TA Aid Room) 170 CE The Center is open Monday through Friday during posted hours.

Computers which have instructional programs for the General Chemistry classes are available on a first come, first served basis. These programs involve only single-concept problems that must be understood in order to deal with the more difficult multi-concept questions on examinations.

Teaching assistants spend some time each week in the LRC to provide contact time with their students and to answer specific questions about their course as well as general questions in any course.

A schedule is posted outside the door which lists the time each TA is available, as well as their course assignment. For over 40 hours per week, teaching assistants are available for help with general chemistry questions. Stop by when convenient to your schedule and take advantage of the resources. You do not need to make an appointment.

Teaching assistants wear a name tag which indicates the course for which they are responsible. There are designated tables for each general chemistry course. However, you do not need to see your TA for help. Any TA should be able to provide assistance. The LRC has limited space and is not designed as a library or study hall, but a place where students can come for individual help and instruction.

Undergraduate Chemistry Office Location: The undergraduate Chemistry office is 110 Celeste Lab. If you missed your first lab or have questions about changing lab sections you need to go to the office.

pg. 6

NOTES ON FINAL GRADE ASSIGNMENTS

To insure consistent grading between parallel sections of the same course, as well as from one semester to the next, grades in all 1000-level chemistry courses are assigned by your instructor in consultation with the Vice chair for Undergraduate Studies. The full details of the grading scheme are too lengthy to describe here. However, the following guidelines may help you better understand the procedure that will be used to determine your grade:

The starting point for assigning final letter grades is to arrange students in order of descending number of total points- 1,000 pts possible (see point breakdown for the course on page 3). No adjustment is made to the scores earned on individual course components (i.e. exams, quizzes, homework assignments, or labs) or to the total points achieved in the course.

The average (mean) total score of all students who finish the course is usually in the C grade range. This means if you finish with a total score near the class average your grade will very likely be C-, C or C+. However, the grade for an average score could fall outside of this range if performance dictates.

All components of the course factor into the total score. In this course, homework, recitation, and lab averages are often in the 80-85% range, while exam averages are often in the 55-75% range. Classes tend

to average about 600-700 total course points.

o To help you consider what your letter grade is on an individual assignment, a grade in the C range (C-, C or C+) is most indicative of an average score. So if a lab report score average is about 83%,

then earning 83% on a lab report would likely be considered a C. Similarly, if an exam average is

65%, earning an exam score of 65% would be in the C range, likely a C.

o Every student will take exams in this class. Those with better knowledge and understanding tend to do better than average. The instructor will typically give information about interpreting your exam

score after each exam in lecture, on Carmen, and/or by email.

If you receive more than 900 total points your grade will not be lower than A.

If you receive less than 500 total points it is likely you will fail the course (i.e. receive a grade of E).

pg. 7

STANDARDS OF ACADEMIC CONDUCT IN GENERAL CHEMISTRY

Violations of academic standards in General Chemistry will be referred to the University Committee of Academic Misconduct (COAM) as required by Faculty Rules. It is the responsibility of COAM to investigate all reported cases of student academic misconduct; illustrated by, but not limited to, cases of plagiarism and any dishonest practices in connection with examinations, quizzes, and graded assignments. Instructors shall report all instances of alleged academic misconduct to the committee (Faculty Rule 3335-5-487). For additional information see the Code of Student Conduct: http://studentaffairs.osu.edu/pdfs/csc_12-31-07.pdf

Student Responsibilities: Any graded material submitted in General Chemistry must represent your own work. This includes exams, quizzes, homework, and laboratory assignments, which are to be an individual effort. Unauthorized group efforts by students, use of another students course materials, or assistance from individuals who already have taken the course, could place you in jeopardy of violation of the standards for General Chemistry. In some courses, group work is acceptable on certain activities (as explicitly stated by your instructor). In these cases, it is important that you know and understand where authorized collaboration (working in a group) ends and collusion (working together in an unauthorized manner) begins. Identical answers indicate copying or unacceptable group efforts - always answer questions in your own unique words. It is important that you consult with your instructor for clarification on whether or not collaboration is appropriate on an activity.

You should not assist others in violating academic standards. Students supplying materials for others to "look at" may be charged with academic misconduct. Never allow another student access to your pre-laboratory exercises, lab reports, or other assignments even after completion of the course. "I didn't know they were going to copy my work" is not an acceptable excuse.

Exams & Quizzes: Examinations are a crucial part of General Chemistry courses, and the integrity of these assessments is taken very seriously. During exams and quizzes, staff will monitor for violations of academic integrity. Any violation, or appearance of a violation, on exams and quizzes will be immediately reported to COAM with a recommended minimum penalty a failing grade for the course. Below is a non-exhaustive list of examples of Academic Misconduct on exams and quizzes:

Viewing or copying others answers, use of crib material (e.g. a cheat sheet), or use of stored constants and formulas in calculators on quizzes, activities, midterm examinations, or the final exam. This kind of behavior is regarded as a severe violation of academic standards, no matter how small the action.

The use of any calculators other than those approved on the course syllabus constitutes academic misconduct. The staff will inspect calculators used on exams and quizzes; unauthorized calculators will be confiscated.

During exams, students are seated with their lab section to facilitate proctoring of the exam. Desks and aisle ways should be cleared of all unauthorized materials, including cell phones or other internet-enabled devices, which should be completely silenced and placed out of sight.

Students should take care to preventatively avoid appearances of academic misconduct during testing. Best practices for avoiding the appearance of academic misconduct include focusing on ones own exam, making efforts to conceal ones own answer sheet and written work on exam pages both during and after the exam, not allowing ones own eyes to wander the room, clearly ceasing working when time is called, and not speaking with other students at any point during the exam, including when in line to turn in the exam. It is the students responsibility to inform the instructor ahead of time of any medical conditions that may result in the exhibition of these behaviors, so that appropriate arrangements can be made.

Unauthorized removal of any exam materials from the exam room will be treated as Academic Misconduct. Laboratory: Laboratory work is the essence of the science of chemistry. All laboratory work in General Chemistry is to be an individual effort. You are expected to perform all parts of the experiments with your own equipment, chemicals, and unknowns. The accumulation of data, calculations derived from that data, and any conclusions or answers to questions associated with that experiment are to be your own work. Academic misconduct involving lab work includes but is not limited to the following:

Laboratory data may not be altered or "made up". All laboratory work must be done in your assigned laboratory room, during your scheduled time period, and under the supervision of your assigned teaching assistant. You are required to have the data sheets/notebook signed by your teaching assistant during lab. Some courses require the submission of carbon copies of the lab notebook every lab period. Violations of these laboratory guidelines will be prosecuted with the minimum recommended penalty of a zero for the entire laboratory component of the course. As stated in the syllabus, a minimum grade in laboratory is required to pass the course, and this penalty can result in an E (failing grade) for the course.

Plagiarism or the submission of work based on old material is considered to be academic misconduct no matter how small the infraction. Possession of another students lab report(s) will raise immediate concerns about academic misconduct.

Evidence of copying or unauthorized "working together" on laboratory course work will be submitted to COAM. The minimum penalty recommended by the Department of Chemistry and Biochemistry will be a zero for the pre-laboratory exercise and the accompanying experiment.

Individuals retaking the course must complete all work for the course during the current semester and may not submit any parts of pre-labs or lab work or reports performed in a previous semester (see item #6 in Ten Suggestions for Preserving Academic Integrity, http://oaa.osu.edu/coamtensuggestions.html).

There are two mandatory quizzes to be taken that are on Carmen - https://carmen.osu.edu . One quiz deals with

Academic Misconduct and the other with the Syllabus. Unless you receive perfect scores on both quizzes, you will not

receive a passing grade in this course. You MUST complete the quizzes before the end of the second week of the

semester (Friday, January 22, 2016) or you could receive an E for the course.

Chemistry 1250 Pre and Post-lab Assignments Spring, 2016

These pre-lab and post-lab assignments are part of your lab grade. The pre-lab marked Carmen is taken on Carmen and is

due before you start the experiment in lab. The post-lab marked Carmen is taken on Carmen and is due one week from the

time you finish your experiment (before you come to your next lab). You should prepare for each lab by reading the

experiment, preparing your notebook and working the pre-lab problems. Pre-labs submitted after the after the lab is

started will receive zero credit. You will use the links listed below for some prelabs and online data input (exps 5, 14

Conclusion Reports are due at the beginning of lab one week after the work is completed. A penalty of 10% per day is assessed for late

labs. After two weeks NO credit will be given. Graded reports should be returned a week after submission - notify your

lecturer if they are not. There is a cut-off date for the first six reports and a cut-off date for all reports. For further information

on lab reports and examples, see the following:

http://undergrad-ed.chemistry.ohio-state.edu/labreports/index.html http://www.chemistry.ohio-state.edu/~rzellmer/chem1210_sample_lab_report.pdf

LABORATORY GRADES: Each lab is worth 110 points (except exp 7 which is 100 points). The points are from

the online pre-labs and post-lab exercises, the notebook grade (10 points) and the report grade, including unknown

grades. A detailed point breakdown may be found on the grading rubric, which can be found on Carmen.

Pre-lab assignments: Must be completed on Carmen prior to the lab. The assignments are shown in the table on

the preceding page. Where it lists Carmen this means there is a quiz on Carmen. The point values for the Carmen pre-labs vary for each experiment (see rubrics for details). The on-line data-entry pre-labs (exps. 5, 14,

16) must also be completed prior to the lab. No credit given if not completed prior to lab.

Post-lab assignments: Will be completed after the scheduled lab time. These, like lab reports, are due 1 week after

completing the experiment. Where it lists Carmen this means there is a quiz on Carmen. The point values for the Carmen post-labs vary for each experiment (see rubrics for details). Post-lab Carmen quizzes will receive zero

credit if done more than 1 week after completion of the lab (i.e. the beginning of the lab period when the report is

due). For the on-line data entry for experiments 5, 14 and 16, partial credit MAY apply.

Note: The Pre- and Post- lab quizzes and on-line pre-lab and data entry are time-sensitive and must be completed

before the due dates and times, no exceptions. Even if you fail to complete or finish a lab you will still have the

information to complete the Carmen post-lab assignments.

The on-line data entry link for the pre and post-labs for exp 5 can be found at:

Prelab: https://undergrad-ed.chemistry.ohio-state.edu/cgi-test/gc-mass-unk-acid.pl

Postlab: https://undergrad-ed.chemistry.ohio-state.edu/cgi-test/gc-mass-unk-acid-results.pl

We are trying something a little new with exp 5 pre-lab. The pre-lab has you watch some videos, answer questions

pertaining to those and the procedure, and then do a numerical pre-lab given randomly generated numbers in the ranges

which you will obtain for your experimental data in exp 5.

The on-line data entry link for the pre and post-labs for exps 14 and 16 can be found at:

http://undergrad-ed.chemistry.ohio-state.edu/genchem/REPORT/ --- then select Prelab or Report

Any requests for re-grading must be made within 1 week of the receipt of a graded lab report, quiz or exam.

Suggestions for Writing Your Notebook Procedure

When writing the procedure in your notebook it must be in your own words, as much as possible, in an outline form (using

reasonably understandable abbreviations when possible is fine). You will learn more from it and remember it better when do

it this way. You should be able to follow your own procedure without looking at the lab manual. Also, someone with a basic

understanding of chemistry should be able to do the experiment by following your procedure. Here are two partial examples:

A partial example of a good procedure (based on exp 6):

Part A:

1a. Obtain 2 Cu cylinders & Styrofoam cup (w. lid) from TA.

1b. Check out flip thermometer from storeroom window (student ID req.)

2a. Hot water bath: 600-mL beaker, ring stand, Bunsen burner.

2b. Weigh the two Cu cyl. to nearest 0.01 g (top-loading bal.).

2c. Carefully place both Cu cyl. in 25-mL test tube

2d. Place test tube in hot water bath.

2e. Let bath come to boil while proceeding to next step.

3a. Weigh clean, dry Styrofoam cup nearest 0.01 g.

3b. Add 60 mL of distilled water to cup.

3c. Reweigh cup and water to nearest 0.01g.

3d. Place cup in 400-mL beaker (for stability).

A partial example of a procedure (based on exp 14):

Part A:

1a. Clean, dry 30-mL syringe (obtained from TA).

1b. Remove glass plunger, rinse with 5 mL acetone.

1c. Lubricate plunger with graphite using pencil, rubbing entire surface.

1d. Temporarily place plunger in 400-mL beaker.

1e. Rinse barrel using 5 mL acetone. Repeat.

1f. Dry barrel by drawing air through it w. aspirator.

2a. Attach serum stopper to syringe (Fig. 14.5, p 99).

2b. Fold back serum stopper before pushing onto Luer-Lok fitting.

2c. Push small end onto Luer-Lok fitting on syringe.

2d. Do not pull on too tightly dont cover slits in fitting.

Note these look like a cookbook using short concise individual steps. This is much easier to read and follow in lab when youre busy, rather than the paragraph form in the lab manual. Plus, doing this helps you to learn the procedure a little better than just copying it word-for-word from the manual. While in lab you can check off each step as you do them to make sure

you dont skip a step or do a step twice. Often, you may have trouble fully understanding what youre supposed to do just based on the written procedure. Watching the lab video for an experiment before or while writing the procedure will often

help in understanding the procedure.

After preparing your notebook answer any pre-lab questions (on Carmen) or do the on-line data-entry pre-lab (depending on

the experiment). You should be able to answer the pre-lab questions if youve understood the Discussion, Procedure and Data Analysis sections. The on-line pre-labs with data entry (exps. 5, 14, 16) will pretty much follow the report sheets you

will use for your data collected in lab for the report (as will the on-line data entry for your results from lab). The on-line pre-

lab data entry programs use randomly generated data similar to what you will collect in lab. These will be easier to do if

youve read the manual and written the procedure first.
