You will need a scientific calculator (not necessarily a graphing calculator). I have always used a TI-30. Just make sure it has keys marked EE, LOG, STO, RCL, etc.
Cell Phones MUST be turned off during class.
There must be NO texting in class. There will be no sharing of calculators or notes.

Attendance Policy: See VSU catalog. One absence is excused in the eight week session. A second absence requires proof of emergency or TAD orders. If a student misses two classes, an "F" will be the course grade. Three "tardies" count as one absence. Being present means being on time for the full time. THIS WILL BE STRICTLY ENFORCED.
Grading Standards
Since much of education is defined as changed behavior, I intend to ensure that idea. This must be very clear to the student. Your work in chemistry should be a building process, since much of what is learned is based on prior learning. You must have the basics in order to progress.
Homework assignments will BE counted. I am interested in your attempt. If you have difficulty with a particular problem, then go to the next one. "I didn't understand any of it" won't fly. I need to see some effort on your part. All work must be shown. No credit for only answers. For EACH missing assignment, I will deduct 2.0 points from your total grade.
Formal lab reports will NOT be required. EACH STUDENT SHOULD HAVE ALL THE DATA. "SO AND SO HAS MY DATA "WON'T WORK!! YOU WILL BE TESTED ON LABORATORY WORK ON EACH EXAM. YOU SHOULD RECORD THE COLOR, ODOR, AND TYPE OF EQUIPMENT BEING USED.
There are three (3) exams. I will only average exam scores if your subsequent score is lower than a previous score. If the subsequent score is higher, then you will get the final highest grade. Each exam will include material from the beginning. The material may be repeated on all exams.
