The Activities will consist of written in-class and take-home assignments, the lowest score for each will be dropped.

A portfolio of online assignments, showing your written work for the Mastering Chemistry problems, will be worth up to 10% extra points in the Online Homework category.

Solutions and explanations should be clear enough so that one of your peers could easily follow what you did if they had not worked the problem before. When a quiz, exam, in-class or take-home exercise calls for a calculated answer, no matter how simple, you increase your chances of arriving at the correct answer (and receiving partial credit) if you show a clear, step-by-step solution using dimensional analysis (unit conversions). This means that you need to show the units (dimensions) on each number and the conversion factor or equation used in each calculation.

Originality. All work must be original and your own. Penalties, such as automatic grades of zero, will result from cheating, copying, plagiarism, or deceit of any kind (SDCCD Policy 3100.3). Plagiarism on an in-class quiz or exam includes use of pre-written hints or notes, looking at another student's paper, allowing (or not preventing) another student to copy your answers, or use of a programmable calculator (see page 1).

Collaboration. I expect and encourage collaboration among you and your peers while working on in-class and take-hom activities, but not on quizzes or exams. In any case, the work you submit to me must be your own, not a copy from another student. The guideline is that you should have no trouble explaining or repeating work that you turn in.

Plagiarism. If you look at someone else's paper during an exam or quiz, or copy directly from another student on any assignment, then you and the person from whom you copied will both earn a zero on the assignment without notice or exception. Mesa College may also wish to pursue academic sanctions, expulsion, and/or legal proceedings. Please be fair.

Make-Up Work. Make-ups are not available for exams, quizzes, and in-class activities, whether your absence is excused or not. Your lowest exam score is dropped if your quiz average is higher.

Take-home activities must be turned in at the beginning of class on the due date. If you will be absent the day that a take-home assignment is due, you may submit your work on time via scan/email, fax, or by dropping it off at my faculty mailbox. You may submit late take-home activities after the due date/time, with grade reduction of 50% per class day starting at the time it is due (i.e., 2:20 pm on the due date).

"You have brains in your head.
You have feet in your shoes.
You can steer yourself in any direction you choose.
You're on your own.
And you know what you know.
You are the guy who'll decide where to go."
~Dr. Seuss
