Messages for Fall Quarter 2013 (posted on 6/13/2013)

Welcome to Chem 161! I'm looking to an exciting quarter and getting to know you! Please pay careful attention to the announcements below.

  1. Please skim through the Fall 2013 Chem 161 course syllabus to learn about class expectations, policies, etc. (Please do not print the syllabus as it will be handed out on the first day of class.)

  2. Purchase ASAP, but no later than Sunday 9/22/2013

    • Chemistry: The Molecular Nature of Matter and Change, 6th edition by Martin S. Silberberg, McGraw-Hill. Earlier editions are okay to use, but page numbers may be a bit different and may not be suitable if you have another instructor for Chem& 162 and 163.

    •  Labs and Active Learning Exercises (ALE's)Print them from the class website (but please print them double sided). It might be simplest and cheaper to print on campus since double sided printing is the default setting at GRCC.

    • Student Lab Notebook with Spiral Binding: 100 Carbonless Duplicate Sets. Hayden-McNeil publishers (available at the GRCC bookstore!!)
