Course Requirements:

  • Book- Chemistry & Chemical Reactivity, 8th Edition by Kotz, Treichel and Townsend (ISBN-13: 978-1-133-35871-8),
  • Subscription to OWL (online web learning,
  • Calculator that adds, subtracts, multiplies, divides and does calculations using exponents will be necessary for the course. 
  • USM e-mail account (, blackboard account (, and access to the Internet. (All students must have active USM accounts that either receives mail or forwards it to your preferred address.)
  • Attendance. You are expected to attend each class. If you miss a class you are responsible for all of the material covered, assignments and      announcements.


Assessment of Performance

iClickers and In-Class Assignments

            Each student will be assigned an iclicker2 to be used every class. You will pick up your iclicker2 at the beginning of each class, and it must be returned at the end of each class. To use the clickers you will need to sign a contract that will be handed out on the first day you sign up to use the iclickers in class. iClickers will be used to track attendance and to answer questions during class. Your daily attendance will be counted as ½ a point towards your grade for each day you attend class for a total of 10 points (you may miss up to 4 class without it affecting your grade). For every day you answer 50% or more of the iclicker questions correctly you will also gain 1 point towards your final grade (up to 10 points). For every point past the maximum that is counted (10 for attendance and 10 for correct questions) bonus points will be added to your final grade.

            During the semester there will also be in-class assignments. These will comprise of group work, short experiments, readings, etc. To get credit for these assignments you must attend the class and hand the written assignment in on time. No assignments will be accepted late, and there will be no make-ups.


Online Homework

            Weekly homework assignments will be given throughout the semester using the OWL homework program. Assignments must be completed by the due date. No late assignments will be accepted. Make sure to check this site regularly for new assignments. To get information on how to sign up for OWL visit the registration and log in page,



There will be three exams, two in class exams and a final. For all exams (including the final) you will be allowed to have a “cheat sheet.” A cheat sheet is one 8 x 11” piece of paper with as much as you can fit on it. Each cheat sheet will need to be handed in with your exam. Make ups are only allowed if you have contacted the instructor BEFORE the exam and the instructor has agreed to allow you to make up the exam. The make-up must be taken before the next class meeting. If class is canceled on an exam day due to the weather the exam will be given during the next class meeting. If class is canceled the day prior to an exam, the exam will be taken on the scheduled date.

The final exam will be the standardized ACS General Chemistry Exam. This exam will cover material from CHY 113 and CHY 115. Your notes from CHY 113 and the material you learn in CHY 115 should prepare you for the final. You may also want to consider purchasing the ACS General Chemistry – Official Study Guide ( The final exam will be May 7, 2012 (unless changed by your instructor). The time and location will be announced in class.



  • OWL Homework (~16%) – 70 points (7 points each)
  • Attendance, Clicker Questions and Assignments (~12%) – 50 points  
  • Exams (~48%) – 100 points (100 points each)
  • Final Exam (~24%) – 100 points

Hint: to calculate your grade add up all of the points you have received so far and divide by the total number of points you could have gotten (420) and multiply by 100%.
