Course Requirements

Major exams: There will be three regular exams and a comprehensive final. There are no make-up exams. Your lowest regular-exam score will count for 10% of your final grade. The other two regular exams will count for 50%. If you miss more than one exam, you get a zero for the second missed exam.

Labs: Lab time will be used to collect data. Students should expect to complete the lab write-up outside of class. Lab reports are due the class following when the lab was completed. You must be present the day the lab is assigned in order to get credit for it.

Group Quizzes: Group Quizzes are in-class assignments to be done in groups of not more than six students who can work together. Grades from thesee quizzes will be combined with lab grades to form a Daily Grade. You must be present the day the lab is assigned in order to get credit for it.

Homework: Online homework assignments are due at midnight the day before the exam covering the same material. Details of how the assignments are graded can be found on eCampus in Lessons->Physics 2425 Handouts->Homework Grading 


Grades will be based on labs, group quizzes and exams.

  • Exams:  There will be three exams and a comprehensive final.
  • Group Quizzes and Labs: Grades from these will be combined into a single “Daily Grade.”
  • Grading summary:  Exams 1-3 (60%), Final (20%), Homework (10%), Daily Grade (10%)

The grading system of Blinn College is as follows*:

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.

Civility Statement

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

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 this semester with a Q is October 8, 2012.

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, a case of scholastic dishonesty, it is critical that written documentation be maintained at each level throughout the process.

Students with Disabilities

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

Final Grade Appeals Policy.  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

Electronic Devices.  All the functions of all personal electronic devices designed for communication and/or entertainment (cell phones, pagers, beepers, iPods, and similar devices) must be turned off and kept out of sight in all College District classrooms and associated laboratories.  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).

Additional Items


Missing any part of lecture or lab counts as one absence.  If a student misses both the lecture and lab periods for a given day, it counts as only one absence.

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]
