Homework Lab Safety Quiz

• HOMEWORK There are two types of assigned
  homework
• 1. End-of-Chapter Homework The lecture notes
  contain suggested homework problems. Try to
  finish these by the end of my lectures over that
  section. I will devote lecture time to answering
  questions over these. These will NOT be graded
  or turned in.
• 2. OnlineHomework www.saplinglearning.com
• These assignments count as 12 of your class
  grade. There is no time limit except for the
  deadline which will be given at the Sapling site.
  The deadlines are firm no hardware, software,
  internet connection, memory, sickness, etc,
  excuses will be accepted if you miss the
  deadline.
• Lab Safety Quiz A tutorial, information, and the
  quiz are available on the Web at the following
  address www.saplinglearning.com (under the
  lab part)
• The login is your student ID without the W and
  without the numbers after the last dash. Password
  last two ID digits first two letters of last
  name, ie for W00182234-11 Jack Smith ID
  00182234 and PW 34Sm. Instructions dates are
  given at the site. Note you have to pass this
  quiz before 12 NOON, Thursday, 1/12/2012 in order
  to stay in chem 122.

Grades Laboratory

• 1. Lab Safety Complete eye coverage goggles
  must be worn at all times obtain them at the
  bookstore. Other requirements are no short
  pants, short skirts, or open shoes no food or
  drinks in the lab.
• 2. General Lab Information Attendance is
  required consult all of the lab material given
  in Sapling especially the policy on missing
  labs the prelab must be finished by the
  preceding Monday, pm. Labs pre-labs will be
  graded on significant figures. During lab
  download complete the post-lab questions. Labs
  are to be turned in at the end of that lab.
• Note Before the lab you need to 1) complete
  the pre-lab by Monday, pm and 2) review lab.
  3) Bring goggles the lab procedure to lab.
• 3. Grade Two exams 44 Final Exam 30
• Lab 14 Online Homework 12
