*Experiment has an unknown which accounts for 10 points.
** A 30 pt. profeciency exm covering nomenclature and unit analysis will be given during the laboratory sections. You must obtain at least 70% on this exam. You will be given three chances to obtain the minimum 70% required. However, the score you obtain on your first attempt will represent the points added to your final grade. In other words, do well on your first attempt. If you do not obtain a score of at least 70% after three attempts, the best grade you can earn in the course is a C-!!!
*** Sections 12 and 13 will review and take the quiz during the first lab period and perform their experiment during the second period since it would be silly to review after the exam. (duh) Section 11 may as a class elect to review right before the exam or during the first lab period.
+ The graph for these lab reports must be computer generated. The Excel tutorial during week 11 is meant to help you with this.
