Course Requirements

GENERAL: You are expected to read your book and keep up with the material day-by-day.  Microbiology is a very demanding and time consuming course so make sure you have a calendar to organize you day and help you to ensure you do not miss any assignments.


Access to the Internet is REQUIRED. Internet access at home would certainly be a plus, however, all students at Blinn College and/or Texas A&M have computing resources available to them. The Open Computer Labs at Blinn College are located in Rooms H-225 and L-258, and the Library. If you are not familiar with these, see me or inquire at the Learning Center in the Library Building, L-258, for more details, ASAP. eCampus is an online course tool. It is in essence a virtual classroom through which I will be posting course related materials and information. You will also be able to contact me with questions and or problems you might be having and have the ability to contact your classmates. It will be your responsibility to check this site regularly:

All lecture notes can be found on ecampus under the “Lessons” tab, in the “Lecture” folder and are organized by chapter.  Before coming into class, you are expected to print the notes so you will be able to concentrate on my lecture and take notes in addition to the bullets that are already on each slide.


We will be using the Pearson publishing program called Masteringmicrobiology which comes packaged with your book when you buy it new from the bookstore or online directly from Pearson.  I will be giving you various assignments from this site throughout the semester that will count towards your overall grade in this class therefore, it is required that you have access to this website.  To gain access to this site you will need to direct your browser to:

LECTURE EXAMS:  There will be four exams worth 100 points each (closed book, no notes, all electronic equipment including cell phones must be TURNED OFF)  that may be a combination of short answer, fill-in-the-blank, multiple choice, identification, and short essay.  Makeup exams will be given at the discretion of the instructor.  Makeup tests are of a different format and contain different questions than the tests given at the scheduled times. After exams are graded, grades will be posted on ecampus.  During the first lecture period following the exam, exam scantrons will be returned to the student for an in class review of the exam with the professor.  Neither questions nor answers may be copied or photographed.  You may come to my office during my office hours and review exams.  A comprehensive, multiple-choice lecture final (worth 200 points) will be given at the end of the semester. The questions on the final will be: 85% from the lecture material covered on lecture exams1-4, 15% from the laboratory material.


ONLINE ASSIGNMENTS:  I will be assigning some online video animations, quizzes, concept map assessments that you will complete.  The following lecture class (after completing the assignment), I will give a follow-up, in-class quiz on the same topics. These grades will be worth 50 points.


LAB EXAMS:  Three 50-point lab exams are scheduled throughout the semester.  The exams will cover material previously covered in lab and will be fill-in-the blank questions, short answer, true or false, and/or labeling.  I do not give makeup lab exams.



LAB ACTIVITIES: Before coming into lab, the student should refer to the Laboratory Schedule handout and read the laboratory modules to be performed in lab that day.  This will help the student to more efficiently budget your time.  Each day in lab all students will be completing lab activities and these same lab activities should be studied before coming into the next lab period.  As soon as we meet for the next lab period, the student will turn in the completed lab activity and a lab quiz over this same material will be given.  Turned in lab activities must be completely filled in and answers must be in complete sentences or the assignment will be graded as a zero.   I will grade the entire lab quiz and selected portions of the lab activity and will total the points from both for one grade.  I will not take late labs unless you have an excused absence as defined by Blinn College Policy.  The grades on the lab activities/quizzes are averaged and will be worth 100 points.


UNKNOWNS:  There will be 3 unknowns assigned during the semester.  Unknowns 1 is worth 25 points, unknown 2 is worth 25 points each and unknown 3 is worth 100 points.  For unknowns #1&2, the student will learn the necessary means to determine the genus and species of each unknown.  The student will be responsible for inoculation of biochemical media with the given unknown bacteria, any necessary staining procedures, recording daily activities and cultural characteristics and the eventual identification (genus and species name) of each unknown they receive.

All student s will be required to photograph their organism in the microscope, biochemical test results and each individual will be responsible for turning in the clear, properly-exposed pictures with the unknown lab report; failure to submit photographs will result in a 20 point deduction from the final report grade.  Post due date, late unknown reports will lose 2 points per day.  More information on the unknown projects can be found in the Laboratory Manual or contacting the professor.

You may need to return to the lab for additional time periods (outside of the scheduled lab times) in order to complete the tests necessary for identification of your unknowns.  Budget your time accordingly to meet assignment deadlines.


             Monday – Thursday:               8:00 a.m. to 8:00 p.m.

            Friday:                                    8:00 a.m. to 12 noon

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

Course Attendance Policy

Tardiness: Class and lab begin on time and you are expected to be in class and lab on time. If you enter the class or lab room within 10 minutes of the beginning of class you will be counted as tardy, after this time you will be counted as absent. If you are tardy to class 3 times during the semester, these will count as one absence. If you have a known problem or time conflict that would not allow you to attend class on time please speak with the instructor before the tardiness occurs.

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 this semester with a “Q” is Friday, April 11th, 2014.

Problem Resolution: If you have a complaint about your class, you should first request a conference with your instructor to try and resolve the problems or issues. If the problems or issues cannot be resolved at the instructor level, you should request a conference with the Division Chair, Mr. Dwight Bohlmeyer, Science 241, [email protected]

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