Course Requirements

Exams are a requirement.  There will be 4 exams worth 100 points each given as indicated in the schedule. Each of the exams will include all of the material covered through that stage of the course. In other words, all exams are comprehensive. The lowest of the four exams will be dropped. The format of the exams may vary. If you miss an exam, this will be the exam that you drop. Make-up exams will be allowed only in exceptional situations, and only at my discretion, but only if taken before the graded exam is returned to the class. The final exam is comprehensive, and is worth 150 points.

Laboratory experiments are a requirement. The laboratory portion of the course counts for 25 % of the course grade. We have 9 labs scheduled, each worth 19 points. You will be graded on your lab report, Lab reports will be due at the beginning of the next lab period after the lab is performed.

Quizzes are a requirement. There will be a number of quizzes given during the semester. There is no make-up for the quiz The top 10 quiz grades will count toward your final score.

Eye protection is a requirement. Students are responsible for purchasing laboratory goggles to wear during laboratories. If a student does not have goggles, they cannot perform the wet lab scheduled for that day.

Close-toed shoes and laboratory dress: When performing wet labs, everyone must be wearing goggles (as described aboves) and they must wear enclosed footwear (closed-toed shoes) that covers their feet entirely. Th shoes must be leather- or runbber-soled. No shoes that are made of cloth should be worn (e.e., ballet flats). As well, the chemistry department has stipulated that everyone performing a wet lab must be covered from the neck to below knees. Shirts must have sleeves, even if short sleeves. If a student comes to lab either uprepared for lab or not appropriately dressed for lab, he or she will not be allowed to perform the wet lab, and a grade of zero will be assigned for the lab.



Grades will be calculated in the following manner:

Lecture points possible

              Exams (4 exams @100 points each, drop lowest)     300 points

              Comprehensive Final Exam                                     150 points

              Quizzes (top 10)                                                      50 points

              Total points lecture                                                500 points 

              plus 9 labs reports at 19 points each                       171 points

              grand total                                                            671 points

The lecture component is worth 75 % of the total, whereas the lab component is worth 25% of the total.


The range of each letter grade will be assigned at the end of the semester. Based on prior grade assignments, typical grade ranges are:

Total Course Points greater than or equal to 90% = A

Total Course Points greater than or equal to 80% but lower than 90% = B

Total Course Points greater than or equal to 70% but lower than 80% = C

Total Course Points greater than or equal to 60% but lower than 70% = D

Total Course Points less than 60% = F

Blinn College Policies

Blinn College policies on civility, class attendance; scholastic integrity; students with disabilities; final grade appeals; and electronic devices as stated in the Blinn College Student Handbook, Faculty Handbook, Blinn College Catalog and specific technical program handbooks. All policies, guidelines and procedures in the Student and Faculty Handbook and the Board and Administrative Policy Manuals are applicable to this course

Civility Statement

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.

Attendance Policy

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:

  1. 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);
  2. representing the College District at an official institutional function;
  3. high school dual credit students representing the independent school district at an official institutional function; and
  4. 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.

Scholastic Integrity

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.

Students with Disabilities

Blinn College is dedicated to providing the least restrictive learning environment for all students. Support services for students with documented disabilities are provided on an individual basis, upon request. Requests for services should be made directly to the Office of Special Populations serving the campus of your choice.  For the Bryan campus, the Office of Special Populations (Administration Building) can be reached at (979)209-7251.  The Brenham, Sealy and Schulenburg campuses are served by the Office of Special Populations on the Brenham campus (Administration Building Room 104) and can be reached at (979)830-4157.  Additional information can be found at

Final Grade Appeal

If a student wishes to appeal a final grade in a course, Blinn College Board Policy FLDB (Local), Course Grade Complaints, outlines the timeline for the appeal and the four steps in the appeal.  This policy is located in the Blinn College Student Handbook.

Electronic Devices

Cellular telephones and beepers/pagers must be disengaged while the student is in the Blinn College Library or any classroom/lab, unless otherwise instructed. Any noncompliance with this policy shall be addressed in accordance with the College District civility policy (administrative policy).  This information is contained in Blinn College Board Policy FLB (Local).

Course Policies

Attendance Policy Reminder: Missing lecture, lab, or both will count as one absence. For classes that meet twice a week during the Spring Semester (like this class!) two absences count as one week's absence. Students accumulating two week's worth of absences (four unexcused absences) will be dropped from class.

Problem resolution: If you have a complaint about the class, you should first request a conference with your instructor to try to resolve the problem. If the issue cannot be resolved at the instructor level, you shouild then request a conference with the Division Chair, mr. Dwight Bohlmeyer, S241,

Eating and drinking: eating and drinking are not allowed in classrooms or laboratories.
