  • Exam #1 Information

    • Topics covered:
      • Lecture material through Monday, September 8
        • Monday's lecture will be primarily review, discussion, and practice. It will be very important to your ongoing preparation for the exam.
      • Laboratory: Background and problem-solving relating to Density
      • Textbook Chapters 1-3

    • To continue preparation for the exam, the following problem sources will be useful to review:
      • Problems assigned in Chapters 1-3
      • Sapling Problem Sets 1-3
      • Extra Practice on Sapling Learning
      • Extra Practice Worksheets
      • Fall 2012 Exams 1 & 2 (posted on the LECTURE page)

            Important notes on the sample exams:
        • In previous semesters, we had 50-minute lectures. There were more exams that were shorter.
        • This semester's Exam 1 will cover all of the Fall 2012 Exam 1& 2 topics, with the exception of isotopes.
        • The length of this semester's exam will also reflect our longer, 80-minute lecture.
        • The current semester exam will be a mix of multiple choice and free response questions; however, the proportion of multiple choice questions will be greater than in the sample exams.
  • Quiz #1 Information

    • Quiz #1 Keys are posted on the LECTURE page
    • Course Average: 14.7 / 20 (73.5%)
    • Standard Deviation: 3.7 (18.5 %) - reflects a wide range of scores
  • Quiz #1 Score Adjustment:

    • If the percentage you score on Exam #1 is higher than your Quiz #1 percentage, then your Quiz #1 percentage will be replaced by your Exam #1 percentage.

    • This applies only to Quiz #1 and is not likely to be repeated on any future quiz or exam.

    • If you did not do as well on Quiz #1 as you had hoped, make adjustments to the way that you are preparing for the course, so that you will be prepared for Exam #1. The score adjustment offered on Quiz #1 means that a low grade on it will not hurt your overall grade if you make necessary improvements for Exam #1.

    • If you did well, make sure that you are contnuing to properly prepare for the Exam, including newer material. As the semester progresses, you may find that it will take more preparation outside of class to continue to master the concepts.

August 2014

  • Welcome to CHEM 192 - Introductory Chemistry. I am looking forward to a productive, challenging, and rewarding semester.  There is important information below that I would like to share with you regarding the start of the semester.
  • Enrolled students: You are all set. Simply attend your assigned laboratory section and the lecture classes starting on the first Monday of classes, August 18. Both the Monday and Wednesday laboratory sections meet the first week! If you are enrolled in the course, attendance at your assigned laboratory section during the first two weeks of classes is required to make sure that you maintain your enrollment!
  • Waitlisted students: If you are on the course waitlist, continue to check your email up to the first day of classes to see if a spot opens for you. If it does not, attend the first laboratory and lecture class for your preferred course section. At that point, I will be able to give you a good indication of the possibility of adding to the course. During the first two weeks of classes, attendance at both the Monday and Wednesday lectures and either the Monday or the Wednesday laboratory section is required to maintain your waitlist priority.
  • Academic integrity will be be taken very seriously in the course. All students are expected to act with respect and honor codes of student conduct. This topic will be addressed in detail in the first two weeks of classes in lecture and in lab. Please scroll down on this page to read Skyline College academic honesty information.
  • Course Materials:

    • Please see the SYLLABUS for a complete listing of all of the required course materials.

    • The REQUIRED course LECTURE textbook is Introductory Chemistry: A Foundation, 7th Edition (paperback). We will begin using the textbook in the course right away, and it will be important that you have it. If you plan to purchase online, please do so as soon as possible.

      • Please begin reading the assigned readings from Chapters 1, 2 & 3, and working problems at the end of the reading sections. See the LECTURE page for assigned readings.

    • The REQUIRED course LABORATORY NOTEBOOK is a dual-copy, bound, numbered laboratory notebook. An appropriate laboratory notebook for chemistry courses is sold in the Skyline College Bookstore.

    • The REQUIRED course LABORATORY MANUAL is the Skyline College Chemistry 192 Laboratory Manual, which will be provided as handouts and website downloads over the course of the semester.

    • The REQUIRED course online homework system is Sapling Learning:
      • Follow the above link.
      • If you have an account, log in. If you do not have an account, create an account.
      • Please enter your first and last names in the profile as they appear on your official Skyline record. If you go by a different name or a nickname, please put it in parentheses after your first name.
      • Select Skyline College.
      • Select Introductory Chemistry - CHEM 192 - Bates.
      • When you register for the course on the system, you will be able to use it for the first two weeks of the semester for free. You must then pay to continue to have access. This will give those students on the waiting list time to determine if they will be able to enroll in the course before purchasing.

    • Laboratory safety glasses or goggles.

Academic Integrity

  • Academic integrity is an important issue in all academic settings, and will be taken very seriously by the instructor of this course, and the college generally.

  • I recognize that most students conduct themselves with honesty and integrity. I also recognize that the actions of a few dishonest students and the impact of those actions on the academic process necessitate a frank and ongoing discussion of this issue.

  • Please review the Student Handbook information on Academic Integrity.



  • The prerequisite for CHEM 192 is:
    • Successful completion (C or better) of MATH 110 (Elementary Algebra) or equivalent.
  • Please speak with me if you have any questions regarding your preparation for the course, or to if you wish to discuss whether another course is better suited to your academic preparation or goals. Please also ask if you have questions about prerequisites or the petition process.
