Required Materials

Textbook – CATALYST the Pearson Custom Library for Chemistry CHEMISTRY 143 Modesto Junior College

Laboratory Materials – Paper Towels, Liquid Detergent, Goggles

Recommended Materials

Lab Coat


Midterm Exams (4) – 60% (15% each)

Quizzes – 15%

Final Exam – 10%

Lab – 15%

I will replace your lowest exam score, if and only if you take all midterms, by your percentage score on the final exam if it is higher than your lowest exam score.  Otherwise no grades will be dropped.

 I will drop your lowest quiz score and your lowest lab score.

Grading Scheme

A = 90% - 100%

B = 80% - 89%

C = 70% - 79%

D = 60% - 69%

F = 0 – 59%

Assignments may include handouts, web assignments, textbook problems, and in class assignments.  It is the student's responsibility to make sure that they have turned in all assignments on time.

Anyone who misses three (3) or more labs will receive an "F" for the course, regardless of scores on exams and quizzes.


Attendance/Drop Policy

Any student that misses any lecture, discussion, or laboratory before the census date (usually about 2 weeks from the start of class)without letting me know ahead of time may be dropped as a no-show.  However, do not count on me to drop you.  If you plan to drop it is your responsibility to do so.  If you are given an add code by me you must use it before the next lecture or you will not be allowed in the class.  Any student who misses an exam or laboratory without notifying me may be dropped from the course.

Academic Dishonesty

If you are caught cheating on any part of this course you will receive a zero (0) for the assignment you cheat on.  I will also report the incident to the dean of the division as well as the dean of students.  You may not make up any work you cheat on.  If you are caught cheating on a midterm I will not replace that score with your score on the final exam.  Cheating includes, but is not limited to copying work from anyone, falsifying a laboratory report, using a cell phone (for any purpose) during an exam, having or using any source of information not specifically allowed by me during any exam, turning in work that you did not do, looking at someone else’s paper during an exam, changing an answer on your exam after it has been turned in, or communicating in any way with anyone other than me during an exam.

Students With Disabilities

If you have any disability that needs accommodation you must let me know within the first week of class or when you first find out. Once you let me know I will gladly do everything I can to assist you, as long as you can still complete the requirements for the class.  

Late/Missed Assignments

Make-up exams/quizzes will not be given.  Your score on the final exam may be substituted for your lowest exam score or an excused absence from an exam.  An excused absence from an exam is an absence that the student has cleared with the instructor before the exam date.  This will only happen if the excuse is a very good, documented excuse.

Lab Work

There are no make up labs.  If you miss a lab your score for that lab is a zero.  Anyone who misses three (3) or more labs will receive an "F" for the course, regardless of scores on exams and homework..  I will drop your one lowest lab score.  If you are more than 5 minutes late for a lab you will not be allowed to do that lab.  Lab write-ups are due at the end of the lab unless it is an especially long lab, in which case I wilet you know when the lab is due.  If this happens, my initials are required on your work before you leave the lab.  No unauthorized experiments are allowed.  You must follow the safety rules (see handout) at all times.  Failure to do so may result in you being told to leave the laboratory.   If this happens your grade for that lab will be a zero.

If the laboratory is not clean including the back counter, balances, and lids on all chemicals,  at the end of the laboratory period, everyone in that laboratory will have 20 percent deducted from their grade for that experiment.


Quizzes will be given during the first 15 minutes of class on most Wednesdays.  If you are late you do not get extra time, the quiz ends at the same time for everyone.  If you miss a quiz your score for that quiz is zero (0).  There are no make-up quizzes.  The quizzes are all based on the homework problems assigned for that quiz (see the Chem 143 page).  If there is an exam scheduled for that day, there will be no quiz.

Cell Phones

Make absolutely sure that you turn off all cell phones before you come into the classroom.  If you must be in contact you may keep your cell phone on in silent mode only.  If you get a call you must leave the room in order to take it.  Please do not talk on your phone during our lecture.  No cell phones are allowed out during exams.  Violation of this rule will be deemed cheating, no exceptions.

Success in Chemistry

Come to class.  Be conscious during class.  Be prepared for class (read the chapter before we go over it in class).  Listen during class.  Participate in the class.  Take good notes during class.    DO THE HOMEWORK!  There is a clear correlation between these activities and understanding the material well enough to earn a good grade in the class. 

Just like any other endeavor the more you practice the better you get.  A good portion of your grade comes from the midterm exams and the final exam.  In chemistry, practice means doing the homework problems. Go through and do all of the homework problems without looking at anything else, not your notes, not the text, not the solutions manual.  When you get stuck and cannot finish a problem, then, and only then, go to other sources to get over the barrier.  Finish the problem the rest of the way without looking at the solution.  Do every single homework problem in that manner.  Then go back, start at the beginning and do the same thing, going all the way through.  Keep doing this until you can go through every single homework problem without looking at the solution.
