Instructor: Paul McElligott, PhD. Website: pmcelligottcom.com Office Phone: 480.664-5573 (Voice Mail Messages) Office: Adjunct – Not on Campus Department phone: 480.423.6111 (secretary), 423-6103 (stockroom)

1. Required Text: Laboratory Inquiry in Chemistry, Bauer, Birk and Sawyer, Brooks/Cole. 2. The Schedule of Experiments is shown on page 1. Supplemental information and sometimes problems, will be supplied by the instructor on the experiment date. 3. Withdrawal from class is the responsibility of the student and will follow guidelines set by the college/department in the SCC Class Schedule. Failure to withdraw by the required date, including "no shows", results in holding of grades, and an "F" for the course. If you stop coming to class, instructor may drop you with a “Y”. Dropping the course means you also must drop the laboratory. 4. Reports: See the Reports Page 4 for details. Accuracy and organization is important; neatness and conciseness will help you because I have to read it. Example calculations must be shown. Stay the entire lab period to draft the report and get help with calculations as required. 5. Notebooks: A hardbound laboratory notebook is required. Have it there by the second lab class at least. See the instructions, page 5. 6. Due Dates: The reports are due at the beginning of the first lab class the week following the experiment. Experiments may be turned in up to one period later for a loss of 10 points, except for the last two. Reports more than one week late will not be accepted, but recorded as a zero. Recalculations are required for all wrong answers with a loss of 5 points for the first recalculation and five point for each additional recalculation. Recalculated reports are given some points until returned. Corrected reports are due the following lab period. All laboratory reports are due on the last class period. 7. Examinations: Two comprehensive laboratory exams are given on the scheduled dates, each approximately one and one half hours long covering only the first or last half of the experiments. A calculator is required. All setups and work must be shown on the exam paper. Exams are individual. McElligott CHM 151LL.S07 page 3 of 5

8. Make up experiments and exams will be given only at the discretion of the instructor. a. If you are unable to attend due to illness or other matters of an emergency nature, notify the instructor or leave a message with name and a return telephone number. b. Labs missed for reasons of personal convenience shall not be made up. c. All makeup labs should be scheduled with Ms. Fong (423-6103), times are subject to her convenience keeping in mind that an instructor must be present. See your instructor for an explanation of the directions before going into lab.

9. Grades: Each experimental lab period is worth 50 points. The lowest of the 50 points will be dropped.

12 Lab reports @ 50 pts each (lowest 50 pts. dropped) 600 points 2 Lab examinations @ 100 pts each 200 2 Lab Notebook checks @ 25 points each 50 Total possible points 850

Letter grades will be assigned as follows: A 88.0 - 100 % B 78.0 - 87.9 C 60.0 - 77.9 D 50.0 - 59.9 F Less than 50

You will earn the grade you receive and receive the grade you earn. There will be no curved grading. However, the instructor reserves the right to increase (but not decrease) the entire class’ points by a factor. NOTE THIS EXCEPTION: Your points on laboratory reports can AT MOST raise your course grade by one letter grade above your exam average. You must understand the material for tests and not rely on a lab partner.

Teamwork: You will be working with a laboratory partner(s) on set up and data collection. Communicate with that partner, but be responsible to do your share. No reports are group reports. All reports are individual work. If you miss class, you may not use you partner’s data. Each person is responsible for their own notbooks, i.e. do not copy your partner’s. All exams are strictly ATTENDANCE: Attendance is required for all lab periods. If you miss lab, for a valid reason, you must contact Elsa Fong at [email protected] or (480) 423-6105, within 24 hours of the missed lab to arrange a make-up. In addition, you must contact me to notify me of the date you arranged to make-up the lab. Otherwise, if you miss more than 1 lab period with no valid excuse and do not contact me, I have the option to withdraw you (with grade of W or Y, depending).

SPECIAL NEEDS: If you have special needs or disabilities, contact Disability Resources and Services in the Student Center at (480) 423-6517.

IMPORTANT NOTE: Your overall lab grade can be, at most, one letter grade above your lab exam average. Lab exams are individual! In other words, YOU must understand the material and not rely on lab partners. Keep this in mind when collecting data. Since you will be working with lab partners, any collected data must be available to ALL group members. Communicate with those partners, but be responsible for your share. If you miss lab, you MAY NOT use your partners’ data. LAB REPORTS: Accuracy and organization is important! Neatness and conciseness will help you, because I have to read it! Sample calculations MUST be shown. I highly suggest you stay the entire lab period to draft the report and get help with calculations, as needed. The following is a general outline of what should be included in a lab report1:

I. Basics a. Name, instructor name, section, lab report title, partner(s), date, etc. II. Abstract a. Condensed version of the entire lab report (~250 words). b. A reader uses the abstract to quickly understand the purpose, methods, results, and significance of your research. c. Begin the abstract with a brief, but specific, background statement to introduce your report. d. State your main purpose or objective and hypothesis. e. Describe the important points of your methodology (reagents, # of samples, and techniques or instruments used). f. Summarize the main results numerically and qualitatively. III. Introduction a. Why did you study this problem? b. Identify the problem or issue and provide background information that the reader needs to understand your experiment. c. Use any appropriate background information from the lab manual and lectures. d. End with a purpose statement (sometimes in the form of a hypothesis): one sentence which specifically states the question your experiment was designed to answer. e. Use the present tense for most of the information in the Introduction (for current or accepted theory), but the present perfect and the past where logic demands (for specific results of previous studies). IV. Experimental a. What did you do? How did you do it? b. In this section you will describe the experimental design, apparatus, methods of gathering and analyzing data, and types of control. c. Include complete details and write this section clearly enough to allow readers to duplicate the experiment. d. Write in past tense because you have already done the experiment. Use complete sentences, and do not write in the form of instructions or as a list of materials, as in a lab manual. e. Methods adapted from other sources should be referenced. V. Results a. What did you find? b. Present your observations and data with no interpretations or conclusions about what they mean. c. Record all your observations, using complete sentences - usually in the order they were made. d. Tables and figures (graphs, diagrams, etc.) should be used to present the data in a more understandable form. e. All tables and figures must be numbered, in the order they are mentioned. All tables and figures must have self-explanatory captions. f. Here, sample calculations and chemical equations will be included. g. Points will be deducted for incorrect significant figures, if used, in calculations, masses, and volumes. VI. Discussion a. What does it mean? How does it relate to previous work in the field? b. Describe patterns and relationships that emerged. c. Discuss why you observed what you did, how it happened (or the most likely reason), and how it relates to the purpose of the experiment. d. Compare these results to trends described in the literature and to theoretical behavior. e. Support your interpretations with references to course material, the lab manual, or comments from the instructor during the lab. f. Remind the reader of your own results, when relevant, without repeating endless details from results. g. Accept or reject your hypothesis and explain why. It is acceptable to reject your hypothesis as long as you can prove it to be untrue and explain why the results did not turn out as you predicated. You can’t argue the results, but if something went wrong or was damaged, disturbed, or contaminated; if there were changes to the experimental procedure; or if equipment was faulty, you need to include this information and explain how it may have affected the results. h. Your final paragraph is the conclusion. Include a brief restatement of the purpose and the main results and how they are relevant to the field of study. Also include any future direction for your results or changes you would make the next time to produce results that are more significant or noteworthy. i. This section will be written in the past tense when you are describing your experiment, and present tense when comparing to current theory.

151LL LABORATORY REPORTS

POINTS ITEM/SECTION The percent contributation page for all reports must be the top page on any submmitted report or it will be returned ungraded. I keep that page with my notes and your grade. 5 *Purpose/ Introduction: One very brief statement. See your text! 5 *Experimental: By reference to the procedure in the laboratory manual or any source, note any changes, additions, corrections, different equipment, computer software, instruments, etc. Do not give details except changes, unless there are enough to warrant a completely written procedure or you create it. 20 *Results and Discussion: Outline this with partners before writing! Data: pages or tables, correct information, neat, care in collection. Calculations: sample calculations of items in order, easily followed with units and significant figures identified. Questions: answered briefly, completely. Observations: phenomena, principles, changes or differences from expected results. Results: accuracy, precision, errors, figures, graphical or tabular presentation of results to support trends or conclusions. Discussion: principles involved, conclusions , further work suggested or required to complete the concept or extend studies. 10 *Summary: One or two very brief but conclusive statements related to the work performed and the purpose above. Review this carefully with partners before beginning to write! 10 *Accuracy and precision of final results. (Only where a standard is comparable for your results, otherwise I supply the standard.) 50 Total Points Style Notes: -- Use the least possible words commensurate with an accurate explanation. -- Use third person past tense in all reports, each we or I loses 0.5 point. -- Use full sentences, few adjectives or subjective statements not supported by the experimental data. -- Do not use abbreviations except common chemical ones in tables or graphs. -- Give proper credit to any other bibliographical references. -- Name the laboratory partner(s) with whom the work was done, the author partner and the percent participation by each member. Use the text page or a copy for this when available. , 151LL, page 5 of 5

151LL Notebooks Outline, Summary Requirements for keeping a laboratory notebook are for the express purpose of preparing a document adequate for legal presentation of information. It must be done when the work in lab is done, not at the time of grading. Specific Requirements Notebook: This is to be hardbound with all the pages intact and not removable without obvious signs. It should be new. Many varieties are available from office supply stores, bookstores and scientific supply houses. Page numbering: Every page should be numbered consecutively from front to back before writing a word in it. This clearly shows all pages are present. Numbers may be where you choose but must be consistent throughout the book. Identification: On the front cover have your full name and the class section for your course. e.g. 151LL, Tuesday afternoon, section 4002. Inside the front cover put identification adequate to have this returned to you, this may include name, e-mail, telephone, etc. Home addresses are not necessary or advisable. It sometime helps to have in large letters: Please return if found! Table of Contents: Save the first five pages for the table of contents. This starts with the page immediately inside the cover or the first numbered page for books already numbered. Label it as Table of Contents. Keep it updated by page number and titles each week or at home as you do experiments. Having subcategories, particularly for summary tables, help find things easily. Signing: Each day that you are in the laboratory, work should be recorded and data tables entered. Every page should be signed by the student and also signed by a partner with the partner dating his signature. Data and Results: Keep data in the notebook as you go. If you enter a tare weight, record it as a tare. If the balance subtracts out the tare, label it as direct tare. Sometimes this can help when an error is made. Keep copies of lab data or graphs done on the computer, entering them in you notebook by taping. A full sized copy must be in the report but notebook additions may be reduced in size. Errors: When numbers are in error, do not obliterate the incorrect ones! Simply put one line through the incorrect one(s) and write the correct ones above it. Sometimes the carat, ^ may be used to insert an additional number or draw an arrow down to the corrected information. If a whole paragraph or page is necessary after you have already worked on a page, insert a reference to a subsequent page and initial the reference. Keep notes to yourself! Especially write observations of what happens in reactions. Identify the person who does certain operations. Use summaries! Blank Pages and Partial Pages: For the unused bottom of a page or a whole page, put a diagonal line or an X through the unused portion and initial it. If an entire page is in error and you have redone the work elsewhere put an X through the page and identify the page on which the work is continued. Keep the pages used sequential and use notes to say "continued on page 47". This must be readable to your partners and to me. Grading. Grading is done while you take your exams. Turn them in before exam. Syllabus Receipt Scottsdale Community College Chemistry Laboratory l5lLL Spring Evening Session 2007 Sections 735, 7359
