  2. Components experiments discussion 6 (36 points max) experiment analysis report error calculations lecture and exercises written exam ~1.5 hour at the end of semester Marks: preparation / discussions / reports min. 24 points every experiment at least 3.5 points‏ error calculations grade 4 or higher exam grade 4 or higher

  3. Experiments Biology Nanosciences Flash photolysis Vapour pressure Differential scanning calorimentry (DSC) Electrochemistry Kinetic gas theory Viscosimetry Flash photolysis Light scattering Differential scanning calorimentry (DSC) Electrochemistry Kinetic gas theory Viscosimetry

  4. Responsibilities Discussion, experiment: assistants Report correction / discussion, points: assistants Assistants' office hours: Wednesdays, 13:00-14:00 Experiment description / schedule / contact Exam, serious problems: Nico Bruns http://www.chemie.unibas.ch/~pcpraktikum/ user: pc; password: pc

  5. Preparation Discussion / experiment • a date: Zeitplan online • Study & understand the experiment description (script, books, internet, ...)‏ • Discussion: ask if something is unclear • The discussion is not a lecture!

  6. Procedure When? (Zeitplan online)‏ Prepare for the exercise (description, library, textbooks, ...)‏. Discussion NOT ok ok Experiment Report (ONE WEEK!, hand in by email)‏ Make a new date prepare come again. good: points :-)‏ bad: discussion again and correction

  7. Experiment is completed with... ... A report • Do notcopy the experiment description! • General introduction (short)‏ • Background: max. 5 important equations • Data: raw data – data analysis error analysis – final result • Discussion: do the results make sense? no? why not? • Report has to be in english (however, we do not grade for langauge) • Copies of reports from other students (with the same mistakes) or internet resources will not be accepted • Hand report in by email to the assistants.

  8. Experiment is completed with... ... A report • Use Excel (or similar programs)! • Sample protocol can be found on the web-site • (Please note: Error calculation in this protocol is not perfect and will be covered in more detail in the error calculation homework).

  9. Tips Computers: computer room ground floor SECURITY: • Phone numbers in Praktikum room • Characteristics of dangerous substances • Protective glasses / gloves in Praktikum room • First aid, eye wash and fire extinguisher located at door of Praktikum room • No food / drinks / smoking in Praktikum room • Safe clothing including closed shoes

  10. Exam Ca. 1.5 hours long, written 5-6 questions on Praktikum experiments and related problems: • Theoretical background • Method • Experimental procedure • Data analysis • Example calculations • Error calculation / analysis • If failed: Repetitipon exam • Repetition of an experiment • In hopeless cases: repetition of the Praktikum

  11. Dates & important stuff http://www.chemie.unibas.ch/~pcpraktikum/ General_Information_Spring_2013.pdf
