Emergency preparednessThe Sonoma County Junior College District maintains a plan for emergency preparedness in case of any disaster or critical incident occurring. In case of earthquake, fire or similar emergencies, the Chemistry department building (Bech Hall) should be evacuated. The evacuation assembly area is in front of the East exit, in the lawn between Bech, Shuhaw and Baker halls. In case of an emergency, contact the District Police at (707) 527-1000
Attendance policy and due dates for tasks
Attendance Requirements (from the College Catalog)It shall be the policy of the Sonoma County Junior College District to maintain an attendance policy and procedures consistent with state and local requirements.
- Students are expected to attend, and in the case of online classes, participate in, all sessions of the course in which they are enrolled.
- A student may be dropped from any class when that student’s absences exceed ten percent (10%) of the total hours of class time.
- With advanced notice and appropriate documentation, members of the U.S. Military Armed Services and Reservists shall have their absences accommodated due to service obligations provided that satisfactory academic progress is being made prior to suspending their studies. For the purpose of this policy, a student is making satisfactory academic progress so long as, at the start of the absence, the student has the potential to pass the class after completing the remaining assignments.
- Specific courses may have stricter requirements based on professional certification mandates or curricular situations in which absences will severely compromise the learning for other students (such as team or performance ensemble courses).
- Students who fail to attend the first class meeting may be dropped by the instructor. For classes that meet online, students who fail to log on and initiate participation by 11:59 p.m. Pacific Time of the first day of the class may be dropped by the instructor. The start date for full semester online classes is the official first day of the semester; for short-term classes, the first day will be specified in the schedule of classes.
- Instructors are required to drop all No-Show students immediately following the second class meeting. A No-Show is an enrolled student who has not attended any class meeting of the course. For classes that meet online, a No-Show is an enrolled student who has not logged on and initiated active participation by 11:59 p.m. Pacific Time of the second day of the class.
You are expected to attend all lectures. There are no make-up midterms. If you cannot attend a midterm because of legitimate, unavoidable reasons such as illness, injury, or family emergency, you should contact the instructor before the scheduled time for the test.
You must attend all lab sessions. Lab write-ups are due at the end of the next lab session. Late work may be turned in up to one week past due date for half-credit. There are no “make-up labs” scheduled for this semester.
The Sonoma County Junior College District attendance procedure (Procedure 8.1.5P , Revised 2/11/2014) states that students with absences in excess of 10% of the class time may be dropped from the class. According to the scheduled instruction time in this class, excessive absence would be missing more than 13 hours of combined lecture and/or labs. If for any reason you expect to be absent from the lab more than twice in the semester or if you have a conflict with any of the midterms or final, it is in your best interest to take this class at some other time.
Due dates for online assignments
The online component of this class amounts to 10% of your grade, therefore it is in your best interest to start working on your assignments right away. The problem sets in the homework assignments are due on the day of the midterm corresponding to each group of chapters. Only homework completed before the due date counts for grade. Past the due date you will be able to access the problem sets but no grade will be recorded. You need to complete at least 70% of all the homework problem sets in a timely fashion in order to receive full credit for homework (10% of final grade). Your grade for homework will be then the fraction of that 70% that you complete on time. See instructor if you need further clarification on this matter. Please note that although you can enhance your learning experience greatly by trying and eventually completing ALL the problems and learning tools provided in the website, but only the REQUIRED assignments count towards your grade.
Academic integrity policyFrom the college’s academic integrity policy (Policy 3.11 as revised 7/10/2012 )
Sonoma County Junior College District (SCJCD) holds that its primary function is the development of intellectual curiosity, integrity, and accomplishment in an atmosphere that upholds the principles of academic freedom. All members of the academic community - student, faculty, staff, and administrator - must assume responsibility for providing an environment of the highest standards, characterized by a spirit of academic honesty and mutual respect. Because personal accountability is inherent in an academic community of integrity, this institution will not tolerate or ignore any form of academic dishonesty.
Academic dishonesty is regarded as any act of deception, benign or malicious in nature, in the completion of any academic exercise. Examples of academic dishonesty include cheating, plagiarism, collusion, and other academic misconduct.
Examination policyThere will be three midterm exams and a final. The midterms will consist of questions and problems related to the content of the chapters indicated in the schedule. The final will be a comprehensive exam of all the subject matter covered in the course and will take place on Tuesday, May 24, 4:00 – 6:45 pm.. If you have a scheduling conflict for the final, let the instructor know as soon as possible.
Accommodations for students with disabilitiesIf you need disability-related accommodations for this class, such as a note taker, test taking services, special furniture, use of service animal, etc., please provide the Authorization for Academic Accommodation Authorization (AAA letter) from the Disability Resources Department (DRD) to me as soon as possible. You may also speak with me privately during office hours about your accommodations. If you have not received authorization from DRD, it is recommended that you contact them directly. DRD Bertolini Student Center, 3rd Floor (East wing).
Course description and course contentsFor the course description and contents, see the CHEM 1B Course Outline of Record.
Teacher’s expectationsYou are expected to acquire the basic intellectual tools needed for understanding the wide world of chemical interactions from the formation of the simplest molecules in intergalactic space to the inner workings of neurons in the human brain. In order to achieve this, you are expected to come to class every day on time, to read the material suggested in preparation for the lecture, to do all the homework problems assigned, to participate actively in class, to take notes and ask questions, to take all three midterm and the final exam. You are also expected to show respect for your instructor, teaching assistants and staff, to abide by SRJC Student Conduct Standards and by the academic integrity policy regarding the individual authorship of all material that you turn in for grade.
Learning supportSome laboratory experiments will require the use of personal computers with spreadsheet, word processor, and data logging programs. The computers are located in each of our Laboratories and in the Mathematics Department Computer Lab in Shuhaw Hall, in the Multi- Curricular Computer Lab in Barnett Hall, and in the Computer Lab on the Petaluma Campus.
If you have any problem, opinion, issue, comment, suggestion, in short, anything that could improve your experience taking this class, or the experience of your fellow students, or that of your instructor, please do not hesitate to contact the instructor in person, during office hours, after class or at any other time, or use email or the phone.
Each one of the 19 lab exercises plus Chemists at Work will be graded on a scale 0..5, according to a specific rubric that will be discussed at the beginning of each lab. Your grade average will constitute 25 % of the grade in the course.
The laboratory is an essential component of any chemistry course because it provides an opportunity for learning where abstract principles may be brought down to the level of comprehension. However, your laboratory experience will not be complete until all of the data and observations have been properly recorded. Therefore, an accurate record of experimental results is an indispensable part of all scientific work.
In many university, government and industrial laboratories, each scientist must maintain data notebooks in a precise manner which, if necessary, can be admitted as evidence in court should a dispute arise as to the priority of patentable discoveries. In such a notebook, each page is dated and all significant results are witnessed. Of course, we shall not need to take such elaborate precautions, but our awareness of these standard laboratory procedures will serve to remind us that a laboratory notebook is not a private diary. Since the material in the notebook is subject to the scrutiny of others, it must be intelligible to anyone conversant with chemistry, and it must be presented in such a format that leaves no doubt as to its authenticity and reliability.
- Before coming to the laboratory, study the assigned experiment thoroughly until you understand the purpose and procedures of the experiment. Consult with your instructor prior to this time if you encounter difficulties in comprehending the intent of the experiment.
- A bound laboratory notebook (5 5 quadrille-ruled, 10 1/8”× 7 7/8” or similar) must be purchased. At the end of each laboratory period, you must bring your notebook to instructor’s desk for final check and signature. Do not attempt to leave the lab without your notebook signed and dated by the instructor!
- In the event your data notebook is misplaced, its rapid return will be facilitated if you print the following information on the first page:
Your name Your phone number Course #, Section #, Laboratory Hours and Room # Your locker number Your instructor’s name
- All data and observations must be recorded directly and immediately into the laboratory
notebook. Use black or blue ink. Absolutely no pencil marks on your lab notebook. Data may
not be entered on scrap paper and then later transferred into the notebook. When weighing
samples, you must bring your data notebook to the balance rather than entrusting to memory
the 4 – 6 digit mass of the sample. When data are recorded hours or even minutes after that
part of the experiment was conducted, they are inevitably inaccurate records of what actually
happened in the laboratory. Only the original, unedited record has any scientific significance.
It may contain crossed-out
(but still readable!)mistakes or be stained by chemicals. The data must be an honest record of the experiment as you perceived it. Neatness and care are not to be neglected completely since the data must be legible, but they are of less importance than accuracy and honesty. For this reason, laboratory “data” written anywhere but in the official data notebook will be confiscated.
- Your name, the date and the experiment title and number must be written on the top of each lab session record.
- Mistakes should be crossed out, never erased or obliterated. Draw a single line through the mistaken entry and write the corrected value above or beside it. A brief statement of explanation should accompany all deletions. If a considerable volume of data on a page is to be disregarded, cross it out with a single large “X” and explain why you rejected the data. In every instance, the deleted entries must still be legible.
- Record ALL data including masses, volumes, times, temperatures, colors, odors, densities, evidence of physical or chemical changes and descriptions of experimental difficulties. Use the proper units where required. Whenever possible, organize your data in tabular form. Since this written record serves as the basis on which your report will be composed outside of the laboratory at a later date, it is important that a generous amount of information be recorded in the notebook. Remember that your laboratory report may not make reference to any data or observations that are not cited in your data notebook.
- Perform all your calculations notebook. This rule excludes simple addition or subtraction (e.g., mass of beaker and sample minus mass of beaker = mass of sample). As you do your laboratory work, you should be curious about the mathematical results of trials as they are completed. If you don’t perform these calculations at that time, how will you know whether you have all of the necessary data and whether that data is reasonable?
- If you use a spreadsheet to perform part of your computational work, make sure to reference the name of location of the file containing your data. It is your responsibility to be able to produce the file at any later time when requested by your instructor.
- At the end of the laboratory period, carefully check your work for omissions or errors and initial and date the bottom right-hand corner of the last page used that day. Also bring the data notebook to your instructor for his signature before leaving the laboratory.
After the completion of each laboratory session, you must prepare a laboratory report that will be due at the beginning of the next laboratory session.
All lab reports will be submitted electronically as a single Excel workbook for each lab. The report will consist of the a worksheet that should include a summary of your experimental results, the data worksheets outlined in the lab description containing all your data and calculations, a discussion of the results and possible errors.
Neatness, organization, completeness and accuracy of assignments are expected. Any work that is sloppy, poorly organized, incomplete or inaccurately done will be returned with a zero grade and/or instructions to rewrite the report.
Once you have completed your report, answer any post-lab questions in a separate worksheet in the same workbook.
Some of the important parts of your report are described in greater detail below.
|Data||Numerical data should be presented in tables, with headings and clearly labeled rows and columns. Include the units on all measured quantities and detailed observations. Indicate the amount, concentration and identity of the chemicals used. Graphs should be used to illustrate the relationships between the measured quantitites. Graphs must have heading, clearly labeled x- and y axis and include the units. Organization and neatness are extremely important. Do not include graphics as separate worksheets. All graphics must be located adjacent to the data they present.|
|All calculations should be done using the capabilities of the spreadsheet. Absolutely no typed-in results. All final results expressed numerically should be rounded so as to be consistent with the rules for significant figures. Include the units in all calculation. Be sure to insert next to the tables showing calculation results the equation used to link the variables. Equations should be typed using the Insert Equation feature of Microsoft Word or similar software, ex. MathType. Do not type equations directly into the cells. Use text boxes consistently. In some instances, results may be shown effectively in graphical form.|
|Discussion||This is the most critical section of the entire report. Begin your discussion with a consideration of the results just presented in the table of results. Relate them to the objectives set forth in the experiment, and demonstrate your understanding of the concepts used in this exercise. Comment on the precision of your work. Compare your results for accuracy with literature values whenever they are available, and comment on the agreement or disagreement. If you use information obtained from other reference materials, acknowledge these< sources with footnotes (author, title, page number, edition or volume, publisher, date) at the bottom of the page of your report where the borrowed information is presented. Included in this section should be a detailed and quantitative discussion of the errors likely to be found in the data and the influence these errors had on the final results. Experimental error is that error which remains in spite of the experimenter’s best efforts. “Spilling samples, carelessness, misreading the buret, or errors in calculations” are not considered experimental errors. These are mistakes, and they can be eliminated by being more careful and repeating the work. Students are encouraged to consult more advanced textbooks, specific reference books and journal articles containing material related to the experiment being studied. The open stacks and the Reserve Book Desk of the Doyle Library on the SRJC campus, the Sonoma State Library and your instructor’s personal reference library are likely sources of information. The class textbook is not considered a reference book and should never be cited in any of your reports. Never use direct quotations from any of the reference sources. Instead, rewrite the relevant statements in your own words as a way of proving your mastery of the concepts and terminology as they apply to your particular experiment. Of course, still be certain to include detailed footnotes when you do this so that anyone could quickly locate the original source of such ideas. Do not type text consisting of more than a few words directly into cells. Use always text boxes for that purpose.|
Note that you are responsible for the integrity of your electronic data. Always keep your an exact copy of the spreadsheets submitted in your flash drive. Do not reopen this file until you have received and accepted the grade for the corresponding lab. If you have any claim regarding problems with the electronic transmission or with the grading, you will need to resubmit exactly the same file you uploaded on or before the due date (with the same time stamp. Please ask for further instructions if you do not understand what this means).
To upload the report successfully to the Canvas server you need to follow the following file naming instructions: the name of the file will consist of the four-letter abbreviation shown in the schedule for each lab, followed by two digits , starting from 01, showing the version of your file in case you need to submit multiples copies of the same file. For example, the file containing your first lab report should be named “FPDE01.xlsx”. Do not attach your name or anything else as the name of the file. Make sure you are uploading to the correct mailbox in the Canvas page.
A sample lab report is provided your convenience on your section Canvas page. Make sure that your report looks as closely as possible to the sample shown (of course, regarding the format, not the content!)
