11. Course Requirements Must acquire before second lab meeting: CHEMISTRY 133 – Laboratory Manual(Publ: Hayden-McNeil) 8thEdition • Remote Entry Pad • (Turning Point) CHE 133 Supplies: Prescribed Safety Goggles • Prescribed Lab Notebook • Combination lock • Towel • [Calculator] Magic Slide Rule for Hogwarts Students

12. Lab Notebook Not Spiral Composition book, Bound, By You Pre-numbered pages 5 points out of each exercise grade is awarded for proper use of notebook. • Lab notebooks must be used ONLY • to record data collection & analysis • Not for lab lecture notes • Not for other subjects YES! The rule is: “You write down stuff!” Records must be kept in INK! Line out errrorrs! No White Out No Erasures Notebook is for real-time observations, not diary to be reconstructed from memory. Notebooks do not need to be neat. Should be able to reconstruct data sheets from notebook entries!!!!!! Datasheets must have no corrections.

13. What will we do? EXERCISES EXPERIMENTS NOT designed to demonstrate, confirm or verifyPrinciples! NOTdesigned to demonstrate, confirm or verify principles T = Pv/Rn Activities that DO require your developing: Knowledge of Modern Terminology: Pv = nRT Mastery of Modern Equipment Forsooth! Ye shall not dispense water into oil of vitriol P = nRT/v Ideas, Concepts n = Pv/RT Powers of Observation Arithmetic Skills ΔE = q + w v = nRT/P Powers of Deduction Experimental Skills

14. Lab is Separate 133 is not correlated with CHE 129, 131, 141 vs Lab and Lecture Courses are separate! Will use concepts that have not been covered in lecture course. Will explain them as required. 12 Lab meetings: Separate Grades! 1Check-in 2 Laboratory measurement 3 - 11Household "CHEMICAL" Exercises Spectroscopy Chromatography Volumetric analysis Gravimetric analysis Gasometric analysis Inorganic synthesis Organic synthesis To be distributed in Lab 10 Exercises 12Check-out As are shown on lab section schedules

15. Grading What Contributes to Your Grade? On the web – Grading Basis Also in lecture notes Given in lab Given in lab on last day of lab

16. Grading Prelim/Test GRADING, cont’d: • Preliminary exercises(55): • quality of reported observations & analysis (35) • neatness of datasheets (5) • adherence to safety practices (5) • proper use of lab notebooks (5) • answers to pre-lab questions (5) • Test exercises(105): • the above • PLUS • evidence of proficiency in technique, • usually measured by ACCURACY • &PRECISIONin determining an • unknown(50) Absence on any graded item results in 0

17. Grading & Absences Absences and make-up: All lab sections are filled. Room only if absences Unanticipated Absences: Excused absencesare only those justified by a note from a doctor, lawyer, judge, parole officer, etc. Make up of exercise or quiz is generally not possible. After-the-fact written documentation is required Anticipated absences: Must give PRIORNOTICE&written documentation Students are responsible for information presented in lab lectures,whether present or not(e.g., on quizzes) Multiple absences are best remedied by dropping course Absence from 4 or more exercises will result in an F

18. Do We Mark “on a curve”? Frequency No! You perform on a curve! Numerical Grades

19. Fail LETTER GRADE DISTRIBUTION FALL 2011 DeFerred Success Grade Cutoffs: A- > 90% of 1000 = 900 C > 70% of 1000 = 700 B- > 80% of 1000 = 800 D > 60% of 1000 = 600

20. Hogwarts Grades Or, for Hogwarts Students, a Certificate of Wizardry Grade Guidelines: A- > 99% of 1000 = 990 C > 70% of 1000 = 700 B- > 80% of 1000 = 800D > 60% of 1000 = 600

21. Lectures are given a bum rap *! Different Students learn differently – through visual ororal cues; through tactile orkinesthetic cues; alone orinsmall or large groups; in a noisyor quiet environment; through analysisorrepetition; Labs require, provide & measure combined skill sets. knowledge care organization dexterity * bum rap : a false accusation, or an injustice

22. Gradesvs Lectures graph Grade = 415 + 38 L Points out of 950* # of Lectures Attended * Excludes lecture points

23. Why Lectures Reasons to come to Lectures Lectures don’t increase workload Lectures are sometimes fun! Lecture Questions:Answerable by attending lectures Lectures advise you of background, changes in procedures and safety matters.

24. Set Channel 41 If you already have your Turning Point clicker, please set the channel to: 41

25. I have registered my student response in Lecture 01 of CHE 133. • Yes • No • Maybe • I don’t know • What’s a response pad?

26. Q1 Registered? If you answered TRUE, welcome If you did not answer TRUE, be sure to register your clicker in CHE 133 before the next scheduled lecture.

27. How do you register your clicker? • To register your pad you will need: • your Net IDand password - for logging into Blackboard, • your device ID • a connection to the internet • To register your pad: • Log into Blackboard at blackboard.stonybrook.edu • Click on link for appropriate LECTURE section of CHE 133 on right. • In left-hand navigation panel, click on Tools, • Click on Turning Point on the page that appears. • Enter your device ID (on lower back of clicker) - twice • Click on SUBMIT These instructions are on the course web site. http://www.ic.sunysb.edu/Class/che133/turningpoint/tpinstr.html

28. Lecture Grades 10 lectures @ 5 points (maximum) 2 points for attending and answering all questions 3 points for answering all questions correctly − ½ point for each wrong answer − 1 point for each un-answered question You are excused (i.e., earn 2 out of 5 points) for 4 of 10 lectures but We will accept 0 (zero, cero, null, 零, صفر ,μηδέν) excuses for not having answered questions in lecture If you miss a lecture, you can attend the alternate one. My dog ate my clicker broken clicker lost clicker dead battery forgot clicker

29. What Help is Available? Lecture Notes Flow Charts Concept Maps Web Supplements Lecture Videos Help Sessions Office Hours

30. Lecture Notes • The lecture notes are intentionally • incomplete. • They do not include: • background information • animations • most images They are not a substitute for taking notes during lecture. Recommend you print lecture notes before attending and annotate them during lecture*. * between facebook and twitter updates

31. Flow Charts Flow charts are intended to help you plan your lab activities by managing your time efficiently. They usually point out alternate sequences of activities than those shown in the manual.

32. Concept Maps Concept maps are a device that can help you evaluate your depth of understanding of what you WILL DO in the laboratory (as well as in other courses).

33. Supplements on Web The course syllabus web page includes large numbers of links to supplementary information about the subjects of the exercises. These links are intended only for students who are particularly interested in certain topics and would like a more detailed description.

34. Lecture Videos Videos allow students who have missed some aspect of a lecture to review that segment.

35. Help Sessions • Help Sessions • TAs conduct help sessions, • Monday - Thursday, 12:00 PM - 3:00 PM • Individualized meetings to help resolve questions or uncertainties about: • Laboratory background & procedures • Laboratory calculations • Pre-laboratory questions Help Room is 215 Grad Chem Help Sessions are most useful BEFOREyou come to the laboratory / lecture BUT AFTERyou have studied the relevant materials Help Session Schedule will be distributed in lab

36. Office Hours The faculty have posted office locations and office hours. Other times are available by appointment. We welcome your questions about Chemistry.

37. Web Web Course Materials accessible at: http://www.ic.sunysb.edu/Class/che133/ • Includes: • schedule/syllabus • partiallecture notes for exercises • flow charts for exercises • links to full lecture videos • solutions to some pre-lab problems • grading policies • other good stuff

38. Course Home Page http://www.ic.sunysb.edu/Class/che133/

39. Important Web Pages

40. Blackboard • We use Blackboard for: • important announcements, • Clicker management, and • Lecture & Course Grade information The e-mail address we use to reach you is the one in Blackboard. Make sure it is correct! http://blackboard.sunysb.edu/

41. Independence • You will often work in pre-assigned groups. Eachpartner must assume individual responsibility for what is done. • A common gradeis assigned for any common RESULTbut not necessarily for overall exercise. • Each submits an INDIVIDUAL REPORT • with independent presentations and • analyses of the observations. • Grades of team members may differ because of data format, clarity or completeness of report Teamwork is essential, it allows you to blame someone else. If in doubt about some aspect of the exercise, repeatmeasurements or observations yourself!

42. ETHICAL STANDARDS Honesty is the only acceptable best policy • Plagiarism (presenting others’ work as yours) • Unauthorized collaboration on exercises or quizzes • Fabrication of data (dry-lab-ing) • Removing quizzes from quiz room • Taking a quiz in a section other than yours • Using a response pad other than your own • are taken seriously and can result in DISMISSAL • If you are unsure about whether a particular practice is permissible, Ask instructor BEFORE doing it

43. “household” The substances we use in the course are primarily “household” “chemicals” such as:

44. Chemical Pix And, of course, the common solvent: Dihydrogen Monoxide Hazards: Hyperhydration, Drowning

45. Safety Safety Stony Brook takes safety very seriously and has an excellent record. SAFETY = COMMON SENSE 2.8 Million people/yr involved in household accidents  People don’t always exercise common sense GLASS: Don’t cut yourself. Use broom & dustpan available in each lab HOT OBJECTS: Don’t pick them up with bare hands

46. Safety SAFETY DEVICES:TA's will instruct you on the location and use of safety equipment, including: Equipment safety showers, eyewash fountains, fire extinguishers, CLOTHING:No open footwear; No exposed skin other than arms and head.

47. Eyes REAGENTS:while most are household materials, handle them in accordance with instructions. Take special note of hazard warnings. EYES: YOU MUST WEAR SAFETY GOGGLES IN THE LABORATORY AT ALL TIMES! (State Education Law) It is your neighbor’s technique we are concerned with, not yours As part of next week’s exercise, you will be asked to read and sign a SAFETY AGREEMENT Bookstore goggles are high quality (comfortable, etc.) but cost ~$20. We recommend these if you will take more labs. If not, cheaper goggles are available, but they must be splash goggles that comply with ANSI Z87.1

48. CHP X 5.4 - Eye Protection …….. For all general, all organic/inorganic chemistry instructional labs, all personsin the laboratory must wear not safety glasses or spectacles, chemical splash goggles, at all times, even when not performing a chemical operation. It is the responsibility of each instructor to enforce this policy; alternate forms of protection are not permitted. Safety Committee Chem Dept CHP 5 point penalty for not wearing goggles (20 pointsif observed bySafety Committee member)

49. Assignment Read: to learn from what one has seen or found in writing or printing This Week: Read: SUSB-001a, SUSB-002 SUPL-001 Analysis of Experimental Reliability Before Next Lecture, Read: SUSB–003 Intro to Lab Measurement [Try to] Complete Pre-lab assignments SUSB- 003 ANDSUPL-001
