Exam, serious problems: Nico Bruns
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!
Procedure
When? (Zeitplan online)
Prepare for the exercise (description, library, textbooks, ...).
Discussion
NOT ok
ok
Experiment
Make a new date
prepare
come again.
Report (ONE WEEK!, hand in by email)
bad: discussion again and
correction
good: points :-)
Experiment is completed with...
... A report
•
Do not copy 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.
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).
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
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
