However, as there are over 2000 students inCHEM 121, please first ask TAs (teaching assistants) in the Resource Centre forhelp, or use the on-line Discussion Board, before sending me e-mail. Otherwise, I willbe swamped with masses of e-mail, and will likely stop answering any questions by e-mail. Thanks for your understanding. Note that I do NOT check e-mail on weekends.The Resource Centre and Discussion Board are described later on.
    4. 4. 4The Lab ManualPlease purchase a copy of the CHEM 121/123Lab Manual 2012-13 from the UBC Bookstorebefore proceeding any further with thisIntroductory Slide Show as we will be referringto numerous pages in the manual.The manual cover is shown here.Please note: outdated lab manuals should not beused. You MUST bring your lab manual to the check-in lab.
    5. 5. 5Safety in the LabYour physical safety is the number one concern in the lab.Some of the chemicals that you will use can seriously harmyou if you do not observe the laboratory rules. Pleaserespect the safety protocols!Before coming to the lab, please watch the Lab Safety Videoavailable on the laboratory web site at:www2.chem.ubc.ca/courseware/121/
    6. 6. 6Safety in the LabSafety GlassesYou must have eye-protection on at ALL times! Your TA will ask you to leave the lab ifafter repeated warnings you are not wearing any eye-protection.You can rent safety-glasses in the lab for $1 per lab session.Prescription glasses are suitable eye-protection as long as they meet the sizerequirements listed on page 17 (point i) of the lab manual. If your glasses are toosmall, you will have to wear safety glasses on top of your prescription glasses.Contact lenses are not recommended as chemical fumes can melt contacts onto youreyeball! Either wear your prescription glasses, or rent special safety-goggles in thelab.
    7. 7. 7Safety in the LabLab CoatsStudents are required to wear lab coats. Students who do not wear a lab coat willbe discharged for the period and will be given a total mark of zero for the missedlaboratory.Suitable lab coats can be purchased in Chemistry D211 for a discounted price or inthe Bookstore. The lab coats MUST be long and 100% cotton.Room D211 will be open at the following times (watch for the signs):Wed Sep 5 - Fri Sep 7: 9 am to 3 pmMon Sep 10 - Fri Sep 14: 9 am to 2 pmSafety glasses can also be purchased in Room D211 or in the Bookstore.
    8. 8. 8Safety in the LabThe following three points must be strictly adhered to:(1) No open-toed shoes. So that you wont damage your foot if you dropchemicals on it. Please wear closed shoes and socks.(2) Wear long pants. Your legs must be protected.(3) Tie long-hair back out of face. So that it doesnt fall into the beaker full ofacid, or a flame etc.

    10. 10. 10What is involved in chemical research?1. identifying a problem2. finding information in the literature3. posing scientific questions4. formulating a hypothesis5. designing an experiment to test the hypothesis6. learning new experimental techniques7. analyzing data & drawing conclusions8. recognizing safety issuesThere are many steps to performing chemical research. You will be learninghow to do the various things listed below in the CHEM 121 lab course:
    11. 11. 11Chem 121 ExperimentsEach experiment has two parts and lasts two weeks:part A = “Dry Lab Week”This involves doing preparatory work done at home before Part B. You will havean entire week for Part A.part B = “Wet Lab Week”This is the actual experiment performed in the lab.Your are expected to spend an equal amount of time on both parts ofan experiment!Let’s take a look at Part A requirements first…..
    12. 12. 12Part A of an Experiment1. Read the Lab Manual2. Read the On-Line Introductory Material3. Complete the Experimental Design Form4. Attempt the Sample QuizFor example, refer to page 59 of your lab manual for a list of the Dry Lab Weekrequirements for Experiment #3A.At home, prepare for the lab:
    13. 13. 13Part A of an Experiment:(1) Read the Lab ManualA sample page from the lab manualRecall that we want you to learn tothink the way a chemistryresearcher does.The lab manual has thus beenwritten in a manner that is designedto focus and direct this thinkingprocess.
    14. 14. 14Part A of an Experiment:(1) Read the Lab ManualSpecific questions are asked inthe side column of the text.These are meant to focus yourthoughts.A sample page from the lab manualQuestion
    15. 15. 15Part A of an Experiment:(1) Read the Lab ManualAnswers to the questionsare found within the maintext.A sample page from the lab manualAnswer
    16. 16. 16Part A of an Experiment:(1) Read the Lab Manual: ConceptMapsA Concept Map summarizes themost important concepts of theexperiment and theirrelationships.It is a good idea to start readingan experiment with the conceptmap.For example, page 28 of the labmanual has this concept mapfor Experiment #1B.precise
    17. 17. 17Part A Requirements:(2) Experimental Design Form• You are given the necessary background information on concepts and techniques.• You must then piece this information together to devise a procedure that you canfollow in the lab.• Keep it simple….use point-form style.Fill out the Experimental Design Form with steps that you plan on following in the lab.For example, pages 39-40 are the design form for Exp #1B.The lab manual does not provide “easy-to-follow” step-by-stepprocedures for each experiment.Your TA will briefly check your Design Form at the beginning of the in-lab session(Wet Lab Week) to ensure that you havent made a critical mistake.Need help? Check out the Experimental Design Guide on p. 4 in your lab manual.
    18. 18. 18Part A Requirements:(3) On-Line Introductory MaterialThis on-line material is meant to help you design your experiment. There arevarious types of multimedia resources available to you.1. Technique Modules 2. Glossary 3. The Virtual LabThe Dry Lab Week Requirements page for Part A of each experiment lists thespecific On-Line Introductory Material that is available for that experiment.For example, see page 59, point #2. For Experiment #3A, there are two TechniqueModules and a Virtual Lab Interactive Tutorial to be done on-line. Be sure to bringthe Virtual Lab Feedback Form to the Wet Lab.You are strongly recommended to read all On-Line Introductory Materials, assome of the Lab Quiz questions will be based on this material (discussedlater).
    19. 19. 19(3) Introductory Material:Technique ModulesThe modules are located on-line on the Chemistry Laboratory Web Area page.On-line introductory materials are accessed through thelaboratory Connect page. You will need to use yourCWL to sign into Connect.

    20. 20. 20Chem 121 Laboratory Web AreaThe lab Web Area page will load. Notice the various tabs at the top of the page.
    21. 21. 21(3) Introductory Material:Technique ModulesYou will then be taken tothe webpage shown to theleft.Click on the appropriatelinks for the modulesassociated with aparticular experiment.Click on Techniques
    22. 22. 22(3) Introductory Material:Technique ModulesquestionsThe Technique moduleshave pictures of the actualequipment that you willuse in the labs.There are also questionslocated throughout themodules that you shouldconsider answering, asthey might be on the in-labQuizzes.
    23. 23. 23(3) Introductory Material:Technique ModulesYou can use any of the public-access high-speed terminals on campus if you don’thave access at home (SUB, libraries, etc.).Most Technique modules alsohave slide shows that depictexactly how to use variousapparatus, or how to correctly usecertain glassware.These slide shows should greatlyassist you in preparing yourExperimental Design Form.
    24. 24. 24(3) Introductory Material:GlossaryThe following webpage has all of theterms from the CHEM 121 & 123labs listed.You can search alphabetically, orsee which terms are used in eachexperiment.Most definitions have a picture ofthe actual equipment, and there arealso hyperlinks to all similar orassociated terms.This is a purely optional resource.Click on Glossary
    25. 25. 25(3) Introductory Material:The Virtual LabThe Virtual Lab programmeallows you to simulate titrationexperiments.You can fully design yourexperiment using the VirtualLab to test various scenarios.During the Lab Check-InSession there will be a fulldemonstration on how to usethe Virtual Lab.
    26. 26. 26The Virtual Lab softwareTo find the Virtual Lab software, go to the Connect page and click the Virtual LabWeb Area link. Or, from the Techniques page, click on the Virtual Lab link.(1) Click onVirtual Lab(2) Then choose an activity
    27. 27. 27Virtual Lab Feedback FormsThe accompanying Virtual Lab Feedback Form can be printed when the activity hasbeen completed:The VL Feedback Formsare worth 2 -3 marks.
    28. 28. 28Part A Requirements:(4) The Sample QuizEach in-lab session will begin with a 10 - 15 minute quiz. Any materialcovered in that particular experiment’s On-Line Introductory Material maypotentially be asked about in the quiz. Any material found within the labmanual may also potentially be on the quiz.The lab manual has a Sample Quiz for each experiment. These types ofquestions will definitely be on the quizzes. For example, see page 36 of thelab manual for the Sample Quiz of Experiment #1B.The purpose of the quiz is merely to test your level of preparation for theexperiment. It is not meant to be difficult. However, if you have not read thelab manual or the On-Line Introductory Material, you will likely fail the quizzes.
    29. 29. 29Part A of an Experiment:“Dry Lab Week”We have now covered all of the Part A requirements that must be done athome before coming to the lab to do Part B during the “Wet Lab Week”.1. Read the Lab Manual2. Complete the Experimental Design Form3. Read the On-Line Introductory Material. Print out the Virtual LabFeedback Form4. Attempt the Sample QuizEach experiment has a Check-List in the lab manual to remind you of all the DryLab Week components. For example, see the middle of page 36 of the manual.
    30. 30. 30A word of Caution…..If your Experimental Design Form is not filled out at the beginning of the in-labsession, then your TA will know that you are not prepared for the experiment.You may potentially be considered a Safety Hazard to all of the other students.Your TA will ask you to leave and book a Make-Up lab with the LabDirector. You will automatically lose 5 marks for that lab.
    31. 31. 31Need Help? Resource CentreIf you need the help of a TA outside of the lab session, for whatever reason, thenplease go to the Chemistry Resource Centre (room B357). The TAs that staffthis room are not the same people that work in the labs. However, they all haveaccess to the CHEM 121 Lab TA Manuals, and also have access to the ProblemSet Answer Keys for the Lecture material. They should thus be able to help youwith all aspects of both the lecture and lab.The Resource Centre is usually open Mon-Fri, and the hours of operation will beposted on the door.Please do NOT try to contact your regular TA outside of the lab. They are notpaid to do any “out-of-lab” student contact, and are operating strictly under theTA Union’s Guidelines. If you need to hand in a late Lab Report, or give your TAa message, please do so through the Lab Director in room B372.
    32. 32. 32Another resource available to you forhelp is the Discussion Board. This is anon-line bulletin board where you canpost questions to fellow CHEM 121classmates, and hope that you receivean answer.The Discussion Board is not moderatedby the Lab Director or any of the LabStaff. This means that if erroneousinformation is posted, no one will bethere to remove it, so be careful aboutthe quality of advice that you receive.Access to the Discussion Board isthrough the laboratory Connect page.Once you have logged in and selectedthe appropriate Connect coursepage,click on the “Discussions” link.Need Help? Discussion BoardClick here
    33. 33. 33Part B of an ExperimentIn the lab:1. Perform the experiment. Collect Observations and Data onto yourExperimental Design Form.2. Clean up your bench area.3. Mark the Observations taken by a fellow student (Peer Marking).4. Have your TA sign your Experimental Design form.5. Have your TA check your Result and sign your Report sheet.After the lab at home:Finish your Lab Report.
    34. 34. 34What happens in the Lab?During the 3-hour lab period:1. Enter lab rooms (B272 / 370 / 372) and go to your assigned bench (# 1 - 48).2. Store your bag / jacket in cupboards under the sinks.3. Write the quiz (10 -15 min).4. Listen to the Lecturing TA’s brief Intro / Demo lecture (~ 5 min).5. Break into groups with your own TA and discuss the experiment (~ 5 min).6. Have your TA briefly check your Experimental Design Form.7. Begin performing the experiment (no lab partners, except for Exp #3).8. When there are only 20 minutes left, you must begin to clean-up your bench area.9. Complete Peer Marking (instructions will be given in the lab) and have your TA signyour marked Observations on the Experimental Design Form.10.Have your TA check your result and sign the Report Sheet before you leave the lab.Data and observations must be recorded in pen. A lab report that has not been signedby your TA might not be graded.
    35. 35. 35Laboratory ReportsLaboratory Reports are written on Laboratory Report Sheets (coloured pages)provided in the lab manual with each experiment. Some parts of the report must becompleted in class, the rest is done at home after the lab session.For example, refer to pages 41-42 of the lab manual.Reports are due at the beginning of the next in-lab session (normally 2 weeks later).Reports are marked by TAs and returned during the next Wet Lab session for yourinspection only. You may then keep the Cover Page but must return the rest of theLab Report.
    36. 36. 36Reports & Design FormsStudents are encouraged to work together when designing the experiments.However, each person must write their own Experimental Design Form.Students must write their own Lab Reports.Students copying any portion of each others lab reports will receive a "0" onthe entire report. Pay special attention when writing your Discussion toensure that it is unique.
    37. 37. 37Laboratory MarkAll together, the lab is worth 20% of your course mark.You must pass both the lab & lecture components of the course to pass Chem 121.Lab average for 2011 session was 17 / 20.The only people who ever fail the lab are those who miss entire experiments anddon’t schedule Make-Up sessions.
    38. 38. 38Making up a Missed LabStudents are required to complete all of the scheduled experiments inorder to pass the course.If a student misses an experiment, he/she is responsible for arranging amake-up session with the Laboratory Director (Room B372).A make-up session is only permitted under special circumstances;writing a midterm on a lab day is not considered a special circumstance.For details see p. 15 – 16 in your lab manual.
    39. 39. 39How Do you Know What to Do?1. You will receive a Lab ID during the Check-In Week. The Lab ID label will be placed on anappropriate Lab Schedule in your lab manual. This schedule clearly describes when and whatyou must do.or2. Go to the Chem 121 Lab Web Area where you will find an interactive calendar with links foreach assignment.You must login with the correct Group Number to ensure that the calendar matches your ownLab Schedule Sheet. The Group Number consists of the letter (A or B) and the SECOND digitin the Lab ID number. For example, for lab ID B3211, the Group Number is B2.
    40. 40. 40Groups A and BLab students will be split into two groups, A and B.Group A students will all be “in-lab” performing a Wet LabWeek experiment, while Group B students will all be athome doing a Dry Lab Week assignment.On Monday Sept 10th we will post lists in the Laboratory Web Areainforming the Tuesday students whether they are in Group A or GroupB. We will continue posting the lists for other sections one day beforetheir scheduled lab time. The two groups, A and B, will check into thelab at different times during the Check-In Week (Sept 11 - 14).
