Course Requirements

         a. Lectures:  Our course is eCampus supplemented course which allows you to print outline for each chapter ahead   
         of time to be able to listen and participate in class discussion.  Keep in mind that it is only outline, and simply
         studying it alone will not be sufficient to ensure a good grade in this course.  During the lecture, the most difficult
         concepts of a particular chapter will be emphasized, but the students are responsible for all material presented in the
         textbook.  You are expected to read the relevant sections of the chapter beforeyou come to class.  Feel free to ask
         questions relevant to discussed material.  If material is still not clear to you, please, stop by my office to discuss it
        face-to-face in all details until it is completely clarified.


          b. Exams:  Exams will cover material in the textbook, handouts, lectures, homework problems, and labs. There
          will be four major exams worth 100 points each. All exams are closed notes/books format.  Periodic table will be
          provided. You need a scantron, standard calculator, and know how to use it.  There will be several versions of exam
         given, make sure to specify exam version on your scantron, and mark all your answers on your copy of exam before
          you hand it in. Test remains the property of the instructor but you are encouraged to view it in my office after it is
         graded to work those problems that you missed on exam.


         c. Homework:  All homework assignments involve the online homework program “Mastering Chemistry”.  They
         are tailored toward each particular exam, and due on the day of that exam.  All information about the registration for
          this program is given in the student access code kit accompanying your textbook.  You need your Course ID (see   
         the first page of this syllabus) to logon to begin. The grading is based on the following criteria: 

         (1) homework is turned in on time;

         (2) assignment is complete;

        (3) answers are correct.

     You have 6 trials for each problem, except for True/False and Multiple Choice questions for which you have only
     one trial.  At the end of semester (Exam IV day) your access to homework would be cut off by the system.  
     Homework collection and grading will be handled by the system.  If you fail to submit your homework, you will
     receive a grade of zero.


        d. Exam Reviews:  Four exam reviews are included in our Course Information Package.  They give you real
        opportunity to obtain problem-solving skills, practice toward the coming exam, and check your readiness.  Each
        problem should be answered, and all calculations shown on your copy of review.  You should be able to work most
        of the problems.  If you have difficulties answering some questions, use my help and assistance.  If you can’t work
        most of the problems, you also need significant amount of help from the tutor.  You are encouraged to make an
        equation card for each exam (total four cards), so that you can review them before the exam, they are helpful for the


         e. Quizzes:   Unannounced quizzes will be given at the beginning of lecture periodIt will not be possible to offer
        makeup quizzes because they are an extension of lecture discussion and continuation of the dialog between instructor
        and student.


        f. Labs: Lab work consists of the selected experiments which are integrated with the material being presented in our
        course and specified in the schedule.  Each Lab Report (25 points) consists of three components: (1) Pre-Lab
        Questions (5 points), (2) Post-Lab Report and the Experimental Data (Originals) recorded during lab in laboratory
        notebook based on In-Lab Guidelines (15 pts), (3) Post-Lab Questions (5 pts). 

        Pre-Lab Questions must be turned in at the start of the lecture period to receive full credit.  Pre-Lab or Post-Lab Report
        turned in after that time would receive a late penalty (5 points per class period for pre-labs or labs turned in late). 
        Your answers and data are expected to be your own, and not a collective, or team effort, in which case it is treated as
        a plagiarism, and all participants receive grade of zero.  The students are responsible for correct planning of lab time to
        complete all work due on time and in full.

        In-Lab Guidelines suggest a format for you to prepare your Laboratory Notebook ahead of time so that you can
        efficiently collect and record the data needed for each part of the experiment.  Turn in the duplicate pages of your data
        and observations to your instructor, clean your workstation, and sign the lab attendance list before you leave the lab.

        Completed Lab Report which includes (1) Post-Lab Report, (2) Post-Lab Questions, and (3) Original of your
        experimental data (all pages in this particular order, and stapled together) are due the next lab meeting.  If you don’t
        have goggles, or closed toed shoes, or the appropriate attire, you would be asked to leave the lab, and you will lose
        points for this assignment.  There will be no makeup labs.  Pre-Lab and Post-Lab Questions can be submitted for the
        partial credit.  To receive the full credit for a lab, your physical presence in the lab is required. 
        Neatness and completeness of your data and answers are considered when points are assigned.  The questions should
        be answered in full format (direct answer and the reasoning), calculations should be given step-by-step with the related
       equations, units, and the appropriate number of significant figures.  While you are allowed to work in pairs while
       collecting data, this does not mean that you can work in pairs to complete the lab report.  Each student must work
       his/her own lab report.  Copying data, or answers from another student will be considered academic dishonesty and all
       participants will receive a zero for assignment.  The experiments are designed to be practical learning experiences and
       therefore are not graded based only on results.   Labs collected for grading may not be returned.  Labs make up 25% of
       your final grade.


       Answering Pre-Lab and Post-Lab Questions:


    (1)     Carefully read a question, and answer directly what you have been asked.

    (2)     If it is a definition, check a specific chapter in your textbook, or a glossary (at the end of a textbook).

    (3)      If it is a calculation, check lab manual or specific chapter in textbook for the example of such calculation.

    (4)     If they ask - how would your results have been affected, you have to analyze described situation and how it will change your data, and your final result. A simple answer “Data would be affected”, or “It would be too high, or too low”, without appropriate explanation, will receive no points.


       Lab Exam:  Lab exam is scheduled at the end of semester, and is worth 50 points.


       g. Computer Use:  You are expected to use the computer to access eCampus and Mastering Chemistry for this course. 
       Computers are available in the Learning Center and in the Open Computer Labs.


       h. Final Exam: This exam is a comprehensive exam (cover the entire semester). It is worth 200 points and you will
       have two hours for its completion.  Final Exam is scheduled on Saturday, May 4th, from 1:00 p.m. to 3:00 p.m.  in  
       the Science building.  Students may view their final grades in their myBlinn account under the “My records” tab.


             i. Classroom Conduct:   Adult, honest, and courteous behavior is expected.  If you are late, enter the room in such
       way that does not disrupt class.  If you have a question, raise your hand and wait to be called. Chattering, sleeping,
       excessive lateness, unexcused exits from class, talking out of turn, or other disruptive classroom behavior has no place
       in college setting.  If a student is caught cheating (exam, quiz, presentation, lab data/answers, etc.), a written report is
       filed with the division chair, and the academic dean, following with grade zero for the assignment (course).  You are
       allowed to take electronic notes.  Once instructor entered the classroom or the lab, the students have to put their cell
       phones in the backpacks.  Any cell phone or other electronic device personal activities will cost you 3 points from the
       total number of points in the course.  


       j. Exam Conduct:  During exams there are some special rules to insure fairness.  All exams are closed notes/books. 
       Periodic Table would be provided.  Only standard scientific calculators are allowed (no memory/graph features, no
       sharing of calculator with other students).   Make sure you can use such type of calculator ahead of time. Visit the
        restroom, if required, before you receive your exam.  If you must leave the room for any reason, you must turn in your
        exam (exam is over). All students will remove hats and sunglasses before the exam.  At the beginning of the exam
       you would be asked to put your bags, cell phones and other materials on the back of the room. If your cell phone is
       visible during your exam, the exam will be taken up.  Violation of these rules would result in grade zero for the exam.


        k. Laboratory Conduct:  The students work in teams (two students per one team).  In no case will you allowed to
        work in a group consisting of more than 3 students.  The students must wear approved eye protection, closed toed
       shoes, and the clothing that covers skin neck to below the knees, shirts with sleeves, or the lab coat/apron during the
       whole time of the experiment. No spare protection is available.  Failure to follow the safety requirements will result in
       expulsion from the laboratory for the performed experiment.  Each lab period will start with a briefing on the
       experimental procedure and safety.  You can begin the experiment after this section, only when the instructor tells you
       to put on your protective gear and start.  The students are expected to practice safe lab procedures and to clean up the
       working lab area, clean and dry the glassware and replace the items in the storage cabinets where you obtained them. . 
       Failure to clean up your lab area and equipment will result in loss of points (50%).


       l. Make-Up Policy:  There will be no makeup assignments except in case of excused absences.  If an absence is due
       to illness, the student must provide doctor’s note.  The student will be allowed to make up work from days covered
       by doctor’s note.  If an absence is due to a death in the family, the student must provide a copy of the obituary.  If an
       absence is due to an official school function, the student must provide a proper documentation.  For a make-up to be
       given you must explain and provide documentation of why you missed a particular assignment (within 2 days of
       your returning to class).  If your excuse is valid and you have sufficient written documentation, I will fill out the
       required form and place a make- up exam for you in the Learning Center (L258).  Make-up exams can be different
       than the regular class exam.  You will be allowed to make it up before the next regularly scheduled exam.  There is no
       makeup for the missed labs (see the lab section), your presence is required, only Pre-Lab and Post-Lab Questions can
       be submitted for partial credit.


        m. Late Assignments: Assignments turned in late will lose 5 points per class period.


       n. Extra Credit Policies:  Science project would be offered as semester progresses.  A grading would be based on the
       rubric system. 


        o. Help:  Every student should feel free to visit me in my office for my help and assistance.  If you need a lot of help
       for the extended period of time, also, in addition, seek the help of a tutor, or study group.  The free tutors and the
       computerized Chemistry Tutorials are available on several workstations in the Learning Center (L258).  Working hours
       can be found at Blinn College Learning Center website.  Study groups formed with your classmates can be interactive
       and effective.






Grading will be based on a point system outlined below:   

        Four Major Exams (100 points each)   400 points         

        Homework                                             60 points         

        Laboratory Work and Lab Exam         250 points         

        Quizzes                                                  90 points           

        Final Exam                                           200 points         


        Total                                                   1000 points


 The grading system of Blinn College recognizes the following grade values:

        A = 90 –100%    mastery of material

        B = 80 -  89%

        C = 70 -  79%

        D = 60 -  69%

        F =      < 60%


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

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).

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 two absences counts as one week's absence.  Students accumulating two week’s worth of absences (four unexcused absences) will be dropped.

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,

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