A) Reading is a requirement. Pop quizzes may be given to insure that reading is completed before the lecture has been given. Students should read over material in their book prior to attending lecture over that material for each lecture given.
B.) Homework will be weighted by a total of 100 points out of 1000 possible points for the semester. Homework collection and grading will be handled by the online system. An access code must be purchased in order to access this system
C.) Quizzes will be used during class to answer questions for point credit. Quiz points will be weighted by a total of 100 points out of 1000 possible points for the semester.
D.) Exams will be weighted by a total of 400 points out of 1000 possible points for the semester. Each exam counts for 100 points.
E.) The final exam is comprehensive, all multiple-choice and worth 200 points.
F.) Laboratory quizzes are a requirement. There will be 2 lab quizzes based on laboratory material given during the lab period on the days indicated in the attached schedule. The laboratory quizzes are worth 50 points each for a total of 100 pts to be counted toward your final grade.
G.) Laboratory experiments are a requirement. The laboratory experiment portion of this course counts for 150 points of the final course grade. For each experiment or worksheet you will receive a total score between 0 and 15. Worksheets will be provided for you in class. The first few pages for each experiment contains the prelab discussion, experimental procedure and safety guidelines. The last few pages for each experiment contains the prelab, in-lab guidelines, and postlab report.
There are several requirements for each wet laboratory experiment:
1.) The Prelab questions are due at the beginning of the lecture period on the day of the experiment. You should complete these directly on the print out from the experiment’s documents in your lab manual.
2.) The experimental procedure write up and its carbonless copy are due at the beginning of the lab period on the day of the experiment. The experimental procedure should be transcribed onto a new page in your lab notebook. The experimental procedure may be found in the first of the two experiment documents. Begin transcribing where it reads, “Experimental Procedure” and go all the way through (and include) the “Safety” section at the end of the first experiment document. You may paraphrase. You will NOT be allowed to participate in lab without the completed experimental procedure write up in your lab notebook and you will receive 0 points for the postlab report.
3.) The in-lab guidelines and their carbonless copy are due at the beginning of the lab period on the day of the experiment. The in-lab guidelines should be done on a new page in your lab notebook. Directions for the in-lab guidelines can be found in the second of the two experiments documents. You will NOT be allowed to participate in lab without the completed in-lab guidelines and you will receive 0 points for the postlab report.
4.) You must wear appropriate lab attire to be allowed to conduct any wet experiment. Appropriate lab attire consists of full face safety goggles, long pants or a long skirt, and closed toe shoes (no shorts allowed.) Your shirt must have sleeves (no spaghetti straps, cut off sleeves, tank tops or tube tops allowed.) You will NOT be allowed to participate in you do not wear proper lab attire and you will receive 0 points for the postlab report. I you remove your goggles from your eyes at any time during the laboratory period, you will be asked to leave immediately and you will receive 0 points for the postlab report.
5.) Each lab period during which we will conduct a wet experiment will begin with a lecture on the procedure and safety briefing. DO NOT BE LATE TO LAB! I you are late to lab, you will NOT be allowed to participate in lab and will receive 0 points for the postlab report.
6.) Postlab reports are due the day of the next class at the beginning of the lecture period. You should complete these directly on the print out from the experiment’s documents from your lab manual. Postlab reports will not be accepted for credit unless the carbonless copy of your lab data(in-lab guidelines) from your lab notebook is signed by the instructor at the end of the preceding lab period and is turned in stapled to the postlab report. The student is responsible for obtaining the instructor’s signature on the copy of the data sheet at the end of each lab period. The postlab report form must reflect information obtained and recorded in the lab notebook by the student while in the laboratory. If the student does not staple the signed copy of the data sheet with the postlab report, he or she will receive 0 points for the postlab report.
7.) A student should never begin an experiment until they are told to do so. A student will know it is time to begin when the instructor asks everyone to put on his or her goggles and then says, “Go.” If a student is found beginning an experiment without the instructor’s verbal consent, they will be asked to leave and will receive 0 points for the postlab report.
8.) Prelab questions (worth 2 pts) and postlab report forms (worth 3 pts) must be turned in individually (i.e., each student must turn in an assignment). Lab write up worth 10pts. Neatness and completeness of the data sheets, pre-labs, and reports will be considered when points are assigned (i.e., if I cannot read it, I cannot grade it.) Experiments and in-lab worksheets count for 15% of your final course grade (150 pts. Maximum).

Blinn College Policies
Members of the Blinn College community, which includes faculty, staff and students, are expected to act honestly and responsibly in all aspects of campus life. Blinn College holds all members accountable for their actions and words. Therefore, all members should commit themselves to behave in a manner that recognizes personal respect and demonstrates concern for the personal dignity, rights, and freedoms of every member of the College community, including respect for College property and the physical and intellectual property of others.
Civility Notification Statement. If a student is asked to leave the classroom because of uncivil behavior, the student may not return to that class until he or she arranges a conference with the instructor; it is the student’s responsibility to arrange for this conference.
This statement reflects step one in a possible four step process. The Incivility Protocol is detailed in the Blinn College Student Handbook.
The College District believes that class attendance is essential for student success; therefore, students are required to promptly and regularly attend all their classes. A record of attendance will be maintained from the first day of classes and/or the first day the student’s name appears on the roster through final examinations. If a student has one week’s worth of unexcused absences during the semester, he or she will be sent an e-mail by the College District requiring the student to contact his or her instructor and schedule a conference immediately to discuss his/her attendance issues. Should the student accumulate two weeks’ worth of unexcused absences, he or she will be administratively withdrawn from class.
There are four forms of excused absences recognized by the institution:
- observance of religious holy days—The student should notify his or her instructor(s) not later than the 15th day of the semester concerning the specific date(s) that the student will be absent for any religious holy day(s);
- representing the College District at an official institutional function;
- high school dual credit students representing the independent school district at an official institutional function; and
- military service.
Other absences may be considered excused at the discretion of the faculty member with appropriate documentation. A student enrolled in a developmental course is subject to College District-mandated attendance policies. Failure to attend developmental classes shall result in removal from the course as defined by the College District.
It is the student’s responsibility to officially drop a class he or she is no longer attending. To officially drop a class the student must obtain the class withdrawal form from Enrollment Services, complete the class withdrawal form, secure the required signatures, and return the completed form to Enrollment Services. The last day to drop with a Q is according to the Academic Calendar.
Blinn College does not tolerate cheating, plagiarism, or any other act of dishonesty with regard to the course in which you are enrolled. The following text defines the faculty member’s responsibility with regard to the scholastic integrity expectation for this and all courses at Blinn College.
It is the responsibility of faculty members to maintain scholastic integrity at the College District by refusing to tolerate any form of scholastic dishonesty. Adequate control of test materials, strict supervision during testing, and other preventive measures should be utilized, as necessary, to prevent cheating or plagiarism. If there is compelling evidence that a student is involved in cheating or plagiarism, the instructor should assume responsibility and address the infraction. Likewise, any student accused of scholastic dishonesty is entitled to due process as outlined in Blinn College Board Policy FLB (Local). The Scholastic Integrity Policy is located in the Blinn College Student Handbook. In a case of scholastic dishonesty, it is critical that written documentation be maintained at each level throughout the process.
