Announcements & Important Course Information

May 27
  • Thank you for a rewarding and enjoyable semester! I hope that you have a great summer, and I wish you the best in your upcoming academic and personal endeavors.
  • Final Grade Posting
    • Recent Scores and Course Grade Only
    • Complete Listing of All Scores & Course Grade
      • Please note that the Adjusted Course Percent reflects your lowest problem set score dropped. It also reflects your LOWEST Exam 1-5 score being replaced with the average of that exam score and your two highest exam scores or the average of that lowest exam score and the Final Exam score, whichever was higher. For many of you, this resulted in an upwards adjustment of 1-4%, based on your own performance in the class.
  • I will be on-campus on Wednesday, May 28 from ~11:30am-1pm. I have a meeting ending at approximately 11:30, so if I am not back to my office right at that time, I should be soon after. You are welcome to view your final exam at that time, or pick other papers you have not collected. They will also be available for viewing or pick-up during the first week of the Fall semester.

Additional Information

  • 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 lecture and lab. At that point, I will be able to give you a good indication of the possibility of adding to the course.
  • 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 week 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.

    • The REQUIRED course LABORATORY manual/textbook is a customized text that is available at the Skyline College Bookstore.

    • The REQUIRED course online homework system is Sapling Learning.

    • 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.
