GENERAL INFORMATION, LIST OF EXPERIMENTS, AND LABORATORY RULES

COURSE ORGANIZATION

1. First Semester (UN3085): You will focus on experiments related to thermodynamics, physical $B$$B$BB$B$ kinetics (transport phenomena), and chemical kinetics. $C$$C$CC$C$
2. Second Semester (UN3086): The emphasis will shift to quantum mechanics and spectroscopy. To enhance your learning, the first semester is divided into three sequential four-week learning blocks:

ASSESSMENT (Refer to the class schedule on page 10)

Quizzes 1 pM

• On the first $(9/16)$$(9/16)$(9//16)(9 / 16)$(9/16)$, fifth $(10/14)$$(10/14)$(10//14)(10 / 14)$(10/14)$, and ninth $(11/18)$$(11/18)$(11//18)(11 / 18)$(11/18)$ weeks (green shading on the schedule), you will be given a 20 -minute quiz on the experiment you will be performing.

Peer-tutoring

• To assure your comprehension of the material covered in each learning block, on the second (9/23), third $(9/30)$$(9/30)$(9//30)(9 / 30)$(9/30)$, sixth $(10/21)$$(10/21)$(10//21)(10 / 21)$(10/21)$, seventh $(10/28)$$(10/28)$(10//28)(10 / 28)$(10/28)$, tenth $(11/25)$$(11/25)$(11//25)(11 / 25)$(11/25)$, and eleventh $(12/02)$$(12/02)$(12//02)(12 / 02)$(12/02)$ weeks (yellow shading on the schedule) you will be expected to explain to each other the experiment you performed the previous week before starting the experiment. For this purpose, you must distribute the tasks among the group members, i.e., you will be either a teacher or a learner according to the group plan. However, you cannot always play the learner role and hence minimize your teaching.
• For peer tutoring, plan to cover the experimental procedure, safety hazards, theoretical principles, instrumentation handling, data treatment, and error analysis for the given experiment. You will responsibly evaluate each other's ability to facilitate learning using an assessment form prepared for that purpose.

Reporting

due nextweek

• You will present your experimental findings as individual written reports $(\mathrm{W})$$(\mathrm{W})$(W)(\mathrm{W})$(\mathrm{W})$, oral $(\mathrm{O})$$(\mathrm{O})$(O)(\mathrm{O})$(\mathrm{O})$, or poster $(\mathrm{P})$$(\mathrm{P})$(P)(\mathrm{P})$(\mathrm{P})$ group presentations as indicated on the schedule on page 10 . Specifics about the reports are given below. poster board about the

WRITTEN REPORTS (W)

Abstract (5 points): After you have written the entire report, briefly state the purpose of the experiment, indicate the theoretical and experimental plan used, summarize the main findings, and point out major conclusions (50 to 120 words). Do not evaluate, or comment on conclusions in the main text.

GROUP POSTER PRESENTATION (P)

I. Getting ideas:

II. Constructing:

1. We will provide you with a poster board at the beginning of the course. You must reuse the board along the semester so avoid using glue to post the information presented.
2. Divide the poster into sections such as title, introduction, methods, results and conclusions. Indicate by numbering or lettering the order in which these sections should be read; arrows can be used for this same purpose.
3. Improve the graphic impact of the poster by mounting the sheets on colored construction paper. However, keep in mind that simplicity and ease of reading are more important than artistic flamboyance.
4. Choose a simple font such as Times New Roman, Palatino or Helvetica.
5. Use a larger font size, bold or underline to make something stand out. Do not overuse outlining and shadowing.
6. The title should be in very large type, 84 pt. or larger. Your name should also be written in large type such as 72 pt .
7. Do not enlarge photocopies.
8. Text on panels should be between 18 and 24 pt. to be legible. Use double or 1.5 spacing. Focus selectively on major findings (present the details in a handout). Framing the text by putting a box around it will also help readers to focus.
9. Use ChemDraw to represent chemical reactions.
10. Use graphs, charts, figures, pictures, or lists to convey your message effectively. Avoid using tables unless they clearly enhance the presentation of the poster. Include references in a smaller font due to space limitations.

Presenting:

1. Explain what you did, how you did it, and your findings using your poster as guidance. Avoid sounding as if you have memorized a script; be excited about your work.
2. Address questions as appropriate.

NUTS AND BOLTS

(a) PLANNING THE EXPERIMENTS

GENERAL LABORATORY POLICIES

1. Visit the EH&S Environmental Health and Safety at Columbia site and open the Lab Safety, Chemical Hygiene and Hazardous Management Rascal course.
2. Take the TC4951 course, which link I pasted below.
3. Print the certificate or save it as pdf and send it to me and the TA. If you already took TC4951, you must also take TC0950.
   https://research.columbia.edu/lab-safety-chemical-hygiene-hazardous-waste-mgmt-training
   https://www.rascal.columbia.edu/tc/course/TC0950/courseOverview
4. Keep all equipment and working areas in the laboratory clean. At the end of the laboratory period, you are required to clean up your work area and common work areas as required by the instructor.
5. Wash the glassware and properly discard chemical waste.
6. CONSULT AN INSTRUCTOR FIRST when in doubt about how to use a piece of equipment or apparatus.

(b) LABORATORY NOTEBOOKS

1. All data and other primary information on an experiment must be recorded directly in your laboratory notebook. Be sure that the original (white) copy of all data is clear and legible. At the end of the period, you must submit the copy of your data. Spectra should be submitted with your laboratory report as appendices. Reports without these data will not be accepted. DO NOT USE LOOSE SHEETS OF PAPER FOR ANY DATA TAKEN IN THE LABORATORY.
2. Be certain that your name, the name of your partners, the date the data were taken, and the (short) title of each experiment is written on each page before you start taking data. Write subtitles for each part of the experiment. Clearly indicate with titles, headings, and comments what the data refer to, what the units are, and enter data in chronological order. If for some reason the data is not entered
   in chronological order, note this fact in your lab notebook.
3. Indicate any changes from the prescribed procedure that may have occurred. Fully record any difficulties encountered as well as any identifying numbers and/or calibrations on special equipment.
