Taking Attendance Assignment of lab partners Assignment to lab drawer Lab schedule: Laboratory 1—13 Safety “Safety in the Chemistry Lab” handout Safety video—”Starting with Safety” (35 minutes; from American Chemical Society) Safety Contract and Contact Lens Waiver Form Lab Safety Exam Don’t Lay on the Floor Preparation for Laboratory Experiments Bring black pen and “Chemistry Spiral Bound” laboratory notebook to each lab session, as well as lab textbook. Prior to coming to lab, prepare for each experiment by obtaining the following information (1-10) and creating an electronic laboratory report on your computer. Print it out and tape/staple it into your lab notebook. Information to be Placed in Computer and in Laboratory Notebook Prior to Lab 1. 2. 3. Your name and name(s) of lab partner(s) Title of the experiment Date the experiment was performed 4. Abstract—short overview and purpose, names of reactions, summary of techniques to be used (1-4 will be on the cover page of the lab report.) 5. Reference section in lab textbook 6. Write out balanced reactions and side reactions that may occur during experiment. 7. Make a table of all reagents to be used during the experiment, listing recommended amounts (weight and molarity), relevant physical properties, and any hazards associated with the chemicals to be handled. 8. Prepare a flow scheme of all operations in the experimental procedure, if applicable. 9. Write out a list of detailed experimental procedures to be followed during the experiment. 10. Answers to all pre-laboratory assigned questions/problems Preparation of a Pre-Lab Submission Prior to lab, go to the course blackboard site and click on “Pre-Lab Submission”. Next, click on appropriate Pre-Lab #. Now, attach your file with the pre-lab work and click “submit”. The Pre-Lab Submission must match the final lab report handed in a week later with only minor changes. Use of Laboratory Notebook During Lab During the lab, enter all procedural information, data, and observations while performing the experiment into the Laboratory Notebook. This must be done in permanent ink, neatly crossed out and corrected, if a mistake in entry is made. Before leaving the lab at the end of an experiment, the lab notebook must be initialed by the instructor. Individual students are dismissed after they have cleaned their lab bench area and returned all equipment and supplies to their proper places. If this becomes a problem, students will not be dismissed from the lab until everyone is finished and the whole lab is cleaned up. Preparation of Laboratory Reports Lab reports shall be prepared after the lab and handed in at the beginning of the next lab session. Reports must be typed using complete sentences with proper grammar, spelling, and punctuation. Past tense, third person must be used throughout the report. Example of a completed lab report will be posted on Blackboard. Information to be Placed in Laboratory Reports 1 through 10 mentioned earlier 11. Data and observations during the experiment 12. Data analysis 13. Results, which includes the outcomes of the data analysis, such as percent yield 14. Conclusions, which includes discussion of the significance and validity of the results, sources of error, usefulness of techniques and procedures, and how the experiment could be improved in the future. 15. References used in addition to lab textbook 16. Spectra, if applicable 17. Carbon copy pages of notes from the laboratory notebook must be attached to the back of the lab report. “Wax On-Wax Off” “The Karate Kid”, 1984, Columbia Pictures Organic Chemistry Lab may at times seem like “wax on-wax off”; but it is a process for learning. “Don’t forget to breathe.” We will view as much of the movie as we can today and then finish it next week.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
