Learning Activities
This course will include readings in the text with assigned problems, laboratory experiments, unit exams, and a comprehensive final exam.

Evaluation and Grading
Students will be evaluated on all work that is assigned, and grades on all assignments, laboratory reports, and exams will be included in the computation of the course grade. To compute the grade the various learning activities will be assigned a percentage value in the course as follows:

Learning ActivityPercent
Problem Assignments10
Laboratory Reports & Unknown Analyses*35
Unit Exams (3)45
Final Exam10
Total100

At the end of the quarter should the point subtotals for the various learning activities not match this scale the points in each category will be prorated so that a match is achieved.

*Unknown Analyses. Three of the labs you will complete this quarter (Formula of a Hydrate, Hard Water, and Visible Spectroscopy) will require an analysis of an unknown sample. For these labs an additional grade will be assigned based on the accuracy of your analysis. For maximum credit you must be within 5% of the true value. You may repeat the laboratory if your results are unsatisfactory, but you will not earn full credit. Repeat experiments will be done on your own time and must be scheduled in advance with the laboratory technician. Details of the scoring are as follows:

If your results are within ...... then your grade will be:
First AttemptSecond AttemptThird Attempt

College Policies Related to Grades. In accordance with the 2010 GRCC Winter Schedule (p. 3), to declare an intention to be graded pass/no credit the student must file a petition with Enrollment Services no later than February 26. For students who qualify, the registrar will convert the decimal grade submitted by the instructor to credit (P) or to no credit (NC). For more details see the College Catalog.

You should also note that students who earn less than 60% in a class, or who stop coming to class without officially withdrawing, will receive a grade of 0.0. The college includes this grade in the computation of your GPA. Furthermore, the lowest passing grade is 0.7, meaning that no credit is given for a class when a grade lower than 0.7 is earned. The last day to withdraw from a class is February 26.

Special Needs
If you believe you qualify for course adaptations or special accommodation under the Americans with Disabilities Act it is your responsibility to contact the Disability Support Services Coordinator in the LSC and provide appropriate documentation. Disability Support Services is located in LSC–271A and may be contacted at: (253) 833–9111, x 2631.

If you have already documented a disability or other condition which would qualify you for special accommodations, or if you have emergency medical information or special needs I should know about, please notify me during the first week of class. You can reach me at the phone number or e–mail address above, or you can schedule an office appointment to meet me in the office listed above, either during my posted office hours or at another mutually determined time. If this location is not convenient for you we will schedule an alternative place for the meeting. If you use an alternative medium for communicating let me know in advance of the meeting (at least one week) so that appropriate accommodations can be arranged.

Classroom Policies
The following policies are in effect for this class:

Attendance. Participation in the class is an essential part of your success in this course, and you will be expected to attend at all times. When you cannot be in class it is expected that you will notify the instructor of your inability to attend. A voice mail or e–mail message before the missed class, or as soon as possible, will be sufficient. Be sure to review the note below regarding attendance during pre–lab discussions.

Tardiness. Attendance includes being present at the start of class. You will be expected to arrange your activities so that you can arrive in the classroom ahead of the start of the period and are able to complete whatever preparations you need in order to be on task at the start of the hour. It is expected that you understand that late arrivals are extremely disruptive of a class, and as such are disrespectful of classmates as well as the instructor. It is also expected that, with the rare exception of an occasional emergency, everyone will remain for the entire class.

Electronic Devices. For you to be successful in this class it is not enough for you to be only physically present. You must also be mentally present, able to focus on the activities of the class, and not distracted by other concerns or interests. Therefore, you are required to turn off all electronic devices prior to the start of class, and to put them away out of reach. Failure to do so may result in the confiscation of the device. Any exception, which would be for emergency reasons only, must be cleared with the instructor more than 5 minutes before the beginning of class.

Safety. Because of the nature of the laboratory portion of this course safety is a concern of utmost importance. You will be expected to observe the following practices:

  • Notify the instructor immediately when a spill or injury occurs.
  • Immediately discuss with the instructor any situation which you feel may be dangerous or cause you discomfort.
  • Use proper, safe techniques regarding personal safety.
  • Use equipment for its intended purpose only, as directed by the instructor.
  • While enthusiastic participation is encouraged, the class will remain an academic environment in which learning can take place.

Special Note: A student who is not present, or is tardy, for the pre–lab discussions of an experiment will not be permitted to remain in the laboratory while the rest of the class is conducting that experiment, nor will s/he be permitted to conduct that experiment at another time.

Late Policy. Students are expected to turn in all problem assignments and laboratory experiment reports at the beginning of class on the announced due date unless, prior to that day, permission has been granted to turn in the material late. All late work will be assessed a ten percent (10%) loss of credit if turned in within two school days of the due date. After that it will be assessed a twenty–five percent (25%) loss of credit.

Unit tests may not be taken late except under very unusual circumstances. Under no circumstances may the final exam be taken late.

Student Conduct. Students are expected to conduct themselves in an appropriate manner just as they would outside the academic environment. Inappropriate conduct will be addressed verbally as a first warning. The second offense will be addressed in writing to the student and the Dean. The third offense may result in permanent removal from class. (WAC 132J–125–210)

Academic Honesty. Students are expected to produce original work. Another person’s ideas, data, graphics, or text may be used with permission of the creator of the work if the original source is given credit. Any unauthorized use of another person’s intellectual work, or failure to give full attribution, constitutes academic dishonesty. Examples include copying on exams, copying lab reports, falsification of data or calculations, etc. Academic dishonesty will not be tolerated and can result in failure of this course and a letter sent to the Dean. (WAC 132J–125–200)

Antidiscrimination. Discriminatory/derogatory language or actions regarding race, gender, ethnic/cultural background, sexual orientation, and physical/mental abilities will not be tolerated.
