- Lab notebook: The write-up of every experiment constitutes a major portion of the grade for this course. For full credit the write-up of every experiment has be done in your own words. Copying text from the textbook or from another student is considered to be plagiarism and will result in 0 pts for the particular experiment. Furthermore if you happen to "adjust" yields, melting points etc. to any other values than you observed, you may receive 0 pts for that particular experiment. Your lab book will be collected on at least three occasions as announced by your TA.

- The purpose of the quizzes is to verify that you did prepare for the up-coming experiments. There is no quiz in weeks 1, 3 and 14. The quiz in week 10 covers two sets of experiments. The quizzes will be given in the first 5 - 10 minutes of the beginning of each laboratory session. If you are late, you may not be able to take the quiz and a score of 0 pts may be included in the total quiz score.

- TA assessment - General performance in the laboratory. The TA decision to deduct points is final. Points may be deducted for any of the following reasons: a) Your TA considers your behavior in laboratory to be a safety risk for yourself and others. b) The TA has to clean your workspace c) your clothing including your shoes is inappropriate for a laboratory course. – The TA will give you the opportunity to change your clothing and shoes however you will not be able to make-up any missed time.

- There will be no opportunity to make up a missed laboratory period. The UMD policy for excused absences applies.
