LABORATORY:

This is primarily a laboratory course. Laboratory hours are to be arranged with the instructor. You are not to work in the lab except under instructor supervision. The  storeroom  manager (Davinder Johl  PS 8) will provide necessary chemicals  and  equipment for the experiments. The available hours for laboratory  work are: MTW 2 pm-9 pm ; Th 2 pm-5 pm.

A lab schedule is posted on this site showing the nine required experiments from Chapter 29 of the text. Experiments as well as related background must be read prior to beginning laboratory work.  You are expected to follow safe laboratory practices while in the laboratory. An honest and continuously updated, bound, consecutively numbered notebook will be your only source for recorded data (see Chapter 2 of your text).  These notebooks should include a table of contents.  Each experiment report should include :

(1) data and observations, preferably in organized format;

(2) sample calculations;

(3) summary of results, and

(4) discussion of results and errors in the experiment. 

Lab notebooks and homework journals are to be placed in the box on the front bench in PS5 on Mondays. They will be returned on Tuesday or Wednesday. Late reports will receive 1/2 credit.  Expect to spend a minimum of 5 hours per week on lab work and 8 hours per week on homework, lab preparation and study. You would be wise to obtain phone numbers of your colleagues so that you can call them for help.

HOMEWORK AND EXAMS:

Chapters 1-16 and parts of other chapters will be covered. Homework problems for each chapter are assigned on the schedule.  Solutions to the exercises and answers to the problems  are in the back of your text. Consultation with your colleagues is encouraged. You are to maintain a "homework journal" showing your effort on the assigned problems. These will be graded and returned with the lab notebooks.  There will be one midterm and a comprehensive final exam. These exams will emphasize lecture and homework and will be open book/note exams.
