Graphing calculators will not be permitted for exam or quiz use. This syllabus has been constructed to be as complete as possible but is by no means a binding document. I reserve right to alter policies and regulations as needed. 1

2 D2L Website This will contain all pertinent information for this course including: this syllabus, various handouts, your current grade and much more. If you have any problems accessing the D2L site for this lecture let me know ASAP! General Requirements Lecture Attendance: Lecture and discussion attendance is critical to your success and is therefore mandatory! Lecture attendance will be monitored via. eistruction CPS Pulse clickers. Lecture attendance and participation is counted in the Attendance section of the grades and will be taken on most lecture days (beyond the 1st week of class). Discussion: Attendance at discussion sections is mandatory and will be recorded. Discussion attendance will be recorded by your TA throughout the semester and reported to the instructor at the end of the semester for the determination of final grades. You must attend the discussion section for which you are registered. The appropriate discussion sections for this lecture are: Lecture 402 DIS This is where you will receive your graded work, and where you will receive additional instruction. In addition, worksheets and other assignments will be completed in discussion. The discussion portion of the grading scheme below includes discussion worksheets, discussion attendance and participation. Lab: Labs will start the week of January 27, Make sure that you have your lab notebook, safety goggles, are wearing the proper attire, and have completed all pre-lab assignments before your scheduled lab period. You will not be allowed to participate in lab unless you have prepared for the correct lab and pass the lab quiz. The prelab quiz will contribute 20 points towards your total grade for each lab. If you do not pass the prelab quiz, your prelab work will be inspected by your lab TA and they will decide if you need to do more work or if you can continue with the lab, in additional your prelab work will be completely graded per the rubric in the lab manual and at the end of this syllabus. The appropriate lab sections for this lecture are LAB Labs cannot be rescheduled or taken late: you must attend your scheduled lab and personally collect your own data. If you are late for lab, or are not allowed to participate for any reason (grade accommodations are possible for acceptable absences), you will receive a grade of zero (0)for that lab. Failure to follow safety procedures will result in expulsion from laboratory and a grade of zero (0)for the lab. Completed labs are due by the start of the next scheduled lab period. Labs turned in late will receive a score of zero (0). You must attend lab and personally turn in your work(copied labs will earn a zero for all involved) or your lab will be graded as a zero (0).If you get a zero on more than two (2) labs, or you lab average is less than 60%, you fail laboratory and cannot pass the course. Additional information concerning laboratory is included at the end of this document. Lab Practical: If you miss the lab practical in any part, or your total score on the practical is less than 60%, you FAIL the laboratory and CANNOT pass the course. 2

3 Grading Item Points Total Points Letter Grade Attendance and up A / A- Range Discussion Worksheets B+ / B / B- Range Homework C+ / C / C- Range Quizzes D+ / D / D- Range Hourly Exams and below F Range Redemption Exam Extra Credit Laboratory 100 Laboratory Practical 100 ACS Final Exam 200 Total 1050 Exams Hourly and Final Each one-hour exam is worth 100 points; for a total of 300 points (no drops). The cumulative final exam (ACS standardized - covering both Chem 102 and 104)is worth 200 points. Four 1-hour exams are scheduled by the university throughout the semester on Wednesday evenings at 5:30 PM (the official time for this exam is 5:30 PM to 7:00 PM, however these are one-hour exams and the additional time is available at my discretion). See the Course schedule. There will be no early, no late exams, and no make-up exams. If you fail laboratory, score less than 60% on the final exam, or miss the final exam for any reason other than a legitimate documented medical excuse you cannot pass the course, regardless of your other grades. Quizzes There will be a quiz given each week. There will be a mixture of in lecture quizzes (at the end of Monday's lecture) and online quizzes. Each quiz is worth 10 points with the ten highest contributing 100 points to your final grade. For an excused absence the next quiz will count double. Homework There will be weekly homework assigned through McGraw-Hill s Connect Homework System each worth 10 points. Homework will not be graded unless you submit the assignment. There is no possibility for late homework. The ten highest homework grades will contribute 100 points towards your final grade. Do not wait until the due date to begin your homework! This is an online homework system, thus the system is prone to any issues that any other web pages are prone to. If you wait until the due date to start your homework assignment there will be no accommodations made for internet issues. This includes internet outages, computer problems, web site issues, etc... You will be able to redo your homework as many times as you like. Grades improve dramatically when the homework is understood not simple rushed through at the last minute. As an encouragement to start your homework early and to redo your homework you will be given 1 extra credit point (for a max of 5) for each additional homework attempt completed and successfully submitted (before the due date). 3

4 Discussion worksheets There will be worksheets to encourage questions in discussion. These worksheets will be made available via D2L and must be printed out (before discussion) by the student, attempted (before discussion) by the student, and turned in at your registered discussion session (at the end of the discussion session) each week. You will have an opportunity to ask questions about the worksheet material and further work on the worksheet in discussion with the help of the discussion TA. The worksheet will then be turned in at the end of the discussion session for a grade. These will contribute a maximum of 100 points towards your final grade. No makeup worksheets will be given. For an instructor (not TA) excused absence the next worksheet grade will count double. Laboratory Approximately one-fifth of the points available in this course come from laboratory work (100 points lab reports and lab participation and 100 points for the lab practical). To pass this course it is essential to participate in laboratory. For each lab it is expected that you arrive on time, arrive prepared, pass the prelab quiz, participate in the lab, and write your own lab report. Arriving prepared involves many things: All prelab work is completed, you have your lab notebook, you are wearing proper attire, you have your safety goggles. You will not be allowed to participate in the lab unless your TA believes that you are properly prepared for the lab. This can easily be accomplished by arriving on time, arriving prepared, and by passing the pre-lab quiz. If you do not pass the prelab quiz your TA will personally determine if they feel that you are prepared. Important Lab Notes: 1. The lab manual is online and is not allowed in the laboratory in any form. 2. Labs can not be rescheduled or taken late. 3. Unexcused absences from lab result in a zero (0) for that lab (see absences section below). 4. Failure to follow all safety procedures will result in your TA asking you to leave the lab and a zero (0) for the lab. 5. Labs turned in lab will receive a score of zero (0). 6. You must personally turn in your own work. Copied labs are considered cheating and will earn a zero (0) for all involved. 7. If you receive a zero (0) on more than two (2) labs, or your overall lab average is less than 60%, or you fail the lab practical (less than 60%); you fail the laboratory portion of the course and cannot pass the class independent of your other grades in the course. Grading Policy For graded quiz material your TA will be authorized to correct any blatant grading errors (i.e., incorrect addition of points). Your TA will NOT be authorized to change the number of points given for partial credit or change your score on a quiz in any other way. If you believe that your quiz has been unfairly graded you must return the quiz to your TA before the end of discussion section on day that you received it, you may NOT leave the discussion room with the quiz if you want it re-graded. He/she will get the quiz to me and I will re-grade it completely. You should be aware that if you elect to do this, your grade may be higher, the same, or lower, depending on whether or not I believe that other problems may have been graded too generously. 4

5 Absences There are no early, make-up, or late exams, worksheets, labs or quizzes. For a scheduled absence (e.g. University athletics, music, etc.), the course instructor (not TA) must be notified at least 48 hours prior to the absence and if approved accommodations will be made Accommodations include: the next graded item (even if it is a zero) of same type will count double, if there are no more graded items of the type missed then the average of all other items will be used to replace the zero. If an exam, quiz, lab or worksheet is missed for a non-medical reason not approved beforehand, a grade of zero (0) will be given. For medical absences, a typed letter (on medical center letterhead) signed by the physician is required. Accommodations include: the next graded item (even if it is a zero) of same type will count double, if there are no more graded items of the type missed then the average of all other items will be used to replace the zero. Policies UWM: You must follow the policies and procedures outlined in the current Schedule of Classes. See: Department of Chemistry and Biochemistry: You are expected to fully understand the policies posted on bulletin boards across from CHM 195 and adjacent to CHM 164. Drop, Section Change: These are done on PAWS. Make sure to follow all the rules established by UWM and the Department of Chemistry and Biochemistry. Incomplete: An Incomplete can be given only to a student who has been doing satisfactory (C) work but who is unable to continue attending the course for a reason judged valid. The request for an Incomplete must be accompanied by documentation. Academic Dishonesty: Cheating on an examination or other graded material will result in a grade of zero as a minimum consequence. Failure in the course and referral to the Dean may also occur. In short, academic dishonesty in any form will not be tolerated. 5

7 Learning Objectives Because this is a general education course, there are GER Distribution Outcomes of providing the students with a broad body of knowledge (UWM Fac. Doc. 1382, p. 2, II, par 1). Additionally, this course has objectives of: 3. developing of a strong foundation of verbal and quantitative skills 4. understanding the rules of methods and processes (UWM Fac. Doc. 1382, p. 1, par. 2) 5. introducing major concepts of a natural science discipline, providing insights into its breadth and its relationship to other disciplines 6. illustrating relationships between experiments, models, theories and laws 7. illustrating the generation and testing of data and the application of concepts and knowledge to the solution of problems (UWM Fac. Doc. 1382, p. 3, par. 7) In order to set these objectives within the framework of this course, a set of objectives have been designed to give you a better understanding of what you are expected to learn over the course of the semester, and some indication of how it will be measure as to what degree this has occurred. These will be incorporated through all types of assessments but will be formally measured on the weekly quizzes and hourly exams. In order to prepare for this, there will be certain objectives which will be presented each week in discussion with exercises for practice. The examples of how these may be measured are examples ONLY and should not be interpreted as an inclusive check list. Remember, this course builds upon your knowledge in General Chemistry I (Chemistry 102) so this list includes both General Chemistry I and II learning objectives. Objective 1: Understand spatial scale, particularly to the very sizes (on the order of atoms). As an example you should be able to: estimate measurement, conceptualize relative sizes, use measurement tools skillfully, correctly compare numbers, convert measurements and scales, be able to compare specific objects (atoms and molecules, for example) by size and use the atom as a starting point in representing matter and changes.

10 Additional Laboratory Information Laboratory Reports: If you go on to perform research or work as a chemist, you will be required to keep a proper laboratory notebook. In this course a more flexible style has been adopted. Your notebook should contain all the information needed to perform the experiment and your data, observations, and results. All entries must be done in ink (use a black ballpoint pen). The goal is to eff ectively and efficiently communicate what was done during laboratory. Expect that your instructor will check your notebook for completeness before you are allowed to start the experiment. In this section of the course you are allowed to use the bound portion of you laboratory manual during your Laboratory Practical. For each experiment include: 1. Print your name, laboratory section number, and the date on the top of each page of your notebook. Carbon-less copies are best as you must retain a copy of all work you submit for grading. Record everything in ink (use a black ballpoint pen). Page numbers must be sequential and your writing legible or the report will be graded as a zero (0). 2. Title of the experiment (as given in the manual). 3. Answers to all pre-laboratory questions 4. A brief statement of the objectives of the experiment. 5. The experimental procedure in outline form. Essentially, this will be the procedure given in the manual with any additional information you need to complete the experiment. 6. Data and observations. Data is best recorded in tables. Think about the best way to construct these as you prepare for the experiment. As a general rule, you should expect to perform triplicate analysis. Record observations such as color changes, the formation of a precipitate, or a change in the temperature of the reaction vessel as you preform the experiment. 7. Calculations and results. Make sure to include all equations. If the same calculation must be performed a number of times, only one of them should be recorded in detail. Use a spreadsheet program such as OpenOffice calc for plotting and repeated calculations. 8. Conclusions and final results. 9. References (if not included as footnotes). Typically, items 7 and 8 account for at least 50% of a lab. Note: Attending lab and turning something in is not enough for you to get a passing grade in lab. 10

11 Laboratory Grading Rubric 1. (2 points) Name, laboratory section number, and date on each page. 2. (2 points) Title (from the manual). 3. (20 points) Pre-Lab questions. A good answer for the practical application question could result in the addition of up to five points (making the lab worth up to 105 points). The remaining questions are worth fifteen points points All questions answered correctly and the practical application question was answered to an additional depth (including detail beyond one or two sentences and possibly including secondary information) points All questions answered correctly points All questions answered correctly with 1 or 2 incorrect answers, depending on the number of prelab questions (i.e. for pre-labs with 3 or 4 questions one incorrect answer constitutes 15 points; for pre-labs with five or more questions, two incorrect answers constitutes 15 points) points All questions answered, but there were multiple incorrect answers. 0-5 points Most questions answered incorrectly or not attempted. 0 points All questions answered incorrectly or not attempted. 4. (3 points) Objective. 5. (7 points) Procedure. The procedure is outlined in individual steps that identifies: what the student is to do when to record data safety issues or disposal directions time(s) involved 7 points Procedure is complete and not missing individual steps or components listed above. 4 7 points Procedure is missing individual steps or one component listed above. 2 4 points Procedure is missing individual steps and/or one or two components listed above. 0 2 points Procedure is missing individual steps and/or two or three components listed above. 0 points Procedure is missing or inaccurate. 6. (20 points) Data and Observations. These must be recorded in real time, not added later. Sometimes observations are contrary to predictions, it is critical that they be recorded anyway points Includes actual amounts of materials used and complete observations detailing any color change, gas evolution, temperature change, etc. To receive maximum points these must be written in such a way that another chemist could use them as a reference points A complete report, but not terribly detailed would earn 20 points. This grade indicates that an important observation or a very small amount of data was missing. 0 5 points A report with very little detail. Missing data and observations. 0 points The section is missing or shows a gross lack of effort by the student. 7. (2 point) Names and signatures of all members of the assigned group (if applicable, otherwise added to the base). 8. (2 point) Serial numbers of equipment used (if applicable, otherwise added to the base). 9. (20 point) Calculations and Results. 20 points Calculations are correct and all results are presented with proper units. 11

12 10 20 points One of the follow possibilities occurs: Calculations are correct and all results are presented but missing units (1 point per missing unit). Calculations are incorrect with only one mistake in the process (even if it effects more than one calculation) but all results are presented. All results are not presented, but calculations are correct for those presented points Two of the above occur. 0 5 points Calculations are incorrect, all results are not presented, units are missing or incorrect, or calculations are missing. 0 points Section is missing or all calculations are incorrect and all units are missing or incorrect. 10. (20 points) Conclusions points The conclusion: is related to the original problem, is supported by the data, and the implications are completely discussed with little or no error points The conclusion: is related to the original problem, is supported by the data, and the implications are partially discussed with some errors and omissions points The conclusion: draws upon the language of the experiment and presents scientific terms, but does not define or discuss the relevance to the original problem; is in conflict with the experimental results; is related to the problem but is supported by the data to a limited extent. 0 5 points The conclusion: is missing, illustrates inaccurate understanding of the scientific concepts underlying the experiment, is not related to the stated problem, or most implications are missing. 0 points The conclusion: is missing or the conclusion is unrelated to the experiment and not supported by the results. 11. (2 point) References (if applicable, otherwise this is added to the base). A few things take points right off the top. Write the penalty and reason right on their lab. -10 points If the lab was not legibly written in ink, double the points off if it happens a second time, and grade as zero (0) if it happens more than twice. -10 points The first time they miss any portion of the pre-lab talk or come in late, double it if it happens a second time, and record their grade as zero (0) if it happens more than twice. -10 points If they fail to clean up or put equipment away. Auto 0 If you are caught without goggles, you will get a zero (0) on the experiment and asked to leave laboratory. Note that if it happens a second time you cannot pass laboratory. Auto 0 Late labs are not graded and receive a score of zero (0). Put Not Graded, Received Late and the date on the first page. Completed labs are due by the start of their next scheduled lab period. 12
