Homework There are two types of homework Text
and Online

• Text In each PowerPoint set, I suggest a group
  of problems to work. Finish these by the end of
  that lecture series and be prepared to ask any
  questions on these during the lecture. These
  will not be turned in.
• Online There are five online homework sets.
  Access these through my web site, through
  Blackboard, or directly. These are graded there
  is no time limit however, there is a firm
  deadline for each assignment. You can open and
  print these. Once you answer/save these, then
  that grade is entered. The problems come from
  Dr. Gammon. Start on these EARLY some are
  difficult. The Chapter 12 assignment 1 is due
  7/3/2007. The direct URL is http//argon.chem.w

Notes Recommendations

• Download review the lecture notes before the
  lecture. Bring a copy to lecture for note
  taking. Review them again shortly after the
  lecture.
• - Read the chapter before I lecture on it study
  your lecture notes read the chapter again work
  several of each homework problem type and take
  the graded online quiz. Work on any weaknesses.
  
• - We will move along quickly in the class. It
  will be difficult to obtain a good grade if you
  fall behind or if you do not attend.
• Exams cover lecture, homework problems and the
  labs.
• No shorts, open toe shoes, or food are allowed
  in the laboratory.
• Download, read, outline the lab do Prelab
  questions before attending the lab. Bring
  results of prelab quiz to lab.
