Course Requirements


Lecture is a requirement.  You are expected to come to class prepared.  You are responsible for all material contained in the textbook.  You are expected to be reading ahead in the textbook and on average cover one (1) chapter per week.  During the lecture I will cover the more difficult concepts and provide examples but feel no obligation to cover all material contained within the textbook. Questions are welcomed at any time during the lecture.  We will cover chapter 2 (sections 2.7-2.9), chapters 11-17, 20, 22 and 23 this semester. There is a common Final Exam so skipping material is not an option.

Homework is a requirement.  There are Mastering Chemistry chapter assignments for each of the 11 chapters that will be covered. Each of these is worth 10 points.  A code must be purchased in order to access this system. Mastering Chemistry is an interactive system, to receive full credit you will have to "demonstrate mastery" of a particular question set. There is no limit to your attempts. Plan to spend a significant amount of time on Mastering Chemistry (1 to 2 hours per night). Mastering Chemistry keeps track of your progress so you can work on the homework throughout the time (weeks) the assignment is active. If you wait until the week of the exam to begin the assignments you will not have time to complete them. Extensions will only be given in exceptional situations and not as a substitute for bad planning on your part. Your grade on each of the Mastering Chemistry chapter assignments will be posted and kept updated on eCampus. No additional points can be earned on an assignment after the deadline has passed.

Exams are a requirement.  There will be five (5) exams worth 100 points each on the approximate dates indicated in the attached schedule. Each of these exams will include all of the material covered through that stage of the course, i.e., the exams are comprehensive although the most recently covered material will be most heavily emphasized on the exam.  The lowest of the five exam grades will be dropped. Format of the exams will vary.  Because of copyright considerations, you will be allowed to review but not retain or make copies of any exam with multiple-choice questions. Make-up exams will be allowed in exceptional situations at my discretion, but only if taken before the graded exam is returned to the class. The Final Exam is comprehensive, all multiple-choice and worth 200 points.  The Final Exam in this course will be given on Monday May 5 at 10:15 am – 12:15 pm in room S209.

Quizzes are a requirement.  Quizzes may be given any day.  You must be present at the time of the quiz in order to take it.  There are no make-up quizzes.  Only the top 10 quiz grades will be counted.

Laboratory Experiments are a requirement.  The laboratory portion of this course counts for 25% of the total course grade.  We will have 9 experiments and a laboratory FINAL.  You will be graded on the lab report that you turn in which consists of a data sheet (due before you leave the laboratory that day); the pre lab questions, the laboratory report form and the post lab questions (all due the next laboratory period).  Failure to turn in a data sheet for an experiment results in an immediate zero for the experiment (NO EXCEPTIONS). The lowest of your 9 experiment grades will be dropped.  You will lose 5 points per class period for labs turned in late. The Lab Final will require that you individually perform an experiment.  You will be graded on your experimental design, your techniques, the data you collect and record, the calculations required to complete the experiment, and the narrative of your experimental procedure, and the final result of your experiment.

Evaluation


Grading and Grading Policy. CHEM 1412 (4 hr credit) is divided into both lecture (3 hr) and laboratory (1 hr) components. For convenience, the course grade is based upon a 1000 point scale. The lecture will count toward 75% of the final grade (750 pts) and the lab will make up 25% of the final course grade (250 pts). Your grades will be posted on eCampus so you will always know your standing in the course.

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 www.blinn.edu/disability/index.html.

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


Classroom and Laboratory Conduct

When you enter the classroom or laboratory, you are entering a learning environment. As such, disruptions due to inappropriate behavior will not be tolerated. Talking, reading the newspaper, texting, and other activities that disrupt or detract from the classroom or laboratory learning experience will not be allowed. Eating and drinking are not allowed in Blinn classrooms. As previously mentioned, any visible food or drink container (even if it is sealed) is a safety violation in lab and will cause your immediate removal from the laboratory with a grade of zero being assigned for that experiment.

SAFETY IN THE LABORATORY

  1. You must have enclosed chemical resistant safety goggles for the lab. 
  2. No eating or drinking in the laboratory.  Smoking is prohibited in all campus buildings.
  3. Follow Experimental Procedures and additional instructions from your Professor.
  4. Dress defensively.
    1. Feet must be protected from falling broken glassware and splashed chemicals.  No flip-flops, sandals or open-toed shoes will be allowed.
    2. Exposed skin is quite susceptible to injury by splattering of hot or caustic solutions. Normal clothing provides partial protection against these hazards if the skin is covered.  Wear sensible clothing (e.g. jeans, and shirt) that will be no great loss if they get discolored or develop holes from an acid splash.  Regardless you must be covered from you neck (shoulder covered) to your ankles.  Wearing shorts, mid-length pants (Capri style), etc. is not permitted.  You may wish to purchase and wear a lab coat as a second level of protection (coverage to your ankles is still required).  A lab apron provides even greater protection.
  5. Wear enclosing safety goggles (enclosing type) at all times while in the laboratory.  After an initial warning, 5 points will be deducted from your laboratory grade.  Students who must wear contacts need to:
    1. Use enclosing type safety goggles.
    2. Wash hands, eyes, and lenses immediately after the laboratory.
    3. Avoid all unnecessary exposures to volatile corrosives.
    4. Notify the instructor immediately of any eye irritation.
  6. Know the location and know how to use the safety equipment (safety showers, eyewash stations, fire extinguisher). Use them only in an emergency.
  7. Follow all special safety instructions in you laboratory text or noted by your Professor.

Reading assignments

You can expect to cover at least 1 chapter per week and should use this as a guideline to plan ahead. You should have read all of the topics to be covered in each lecture before coming to class. This material is considered to be fair game for the scheduled exams and the final.

Course eCampus

A CHEM 1412 eCampus homepage has been created and can be found at the following Internet address https://ecampus.blinn.edu. This site contains the course information sheet, homework assignments, and any additional lecture notes for the chapter being covered. Note: Simply studying the notes or old PowerPoint lectures provided on eCampus will not be sufficient to ensure a good grade in this course.

Incomplete's

An Incomplete can only be awarded under very specific conditions. Specifically, Incomplete's are awarded only if 90% of the course work has been completed. This means that something has happened at the end of the semester (documented illness, family emergency, catastrophic accident, etc.) and you are missing the last exam or the Final. An Incomplete cannot be given for a crisis at the middle of the semester or for being late for the Final Exam.

An Incomplete requires a contract be written, approved, and signed by the student, the instructor, and the division head prior to the "I" being given. No paperwork, no Incomplete. If you fail to complete the missing work in the specified time, a grade of F will be awarded. Incomplete's do not allow a student to retake the entire course to improve their grade.

Attendance Policy Reminder: Missing lecture, lab or both will count as one absence. Since we meet for an extended time period each day during a 5 week summer session, 1 absence is the equivalent of 1 week. Students accumulating two week’s worth of absences (2 class periods) will be dropped.

Last day to drop classes w/a “Q”- Spring 2014: Friday April 11th

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, dbohlmeyer@blinn.edu.

Tentative Laboratory Schedule

You will perform 9 experiments this semester. You will be graded on the Pre-Lab Questions, the experimental data sheet (due at the end of the laboratory period), the laboratory report and Post-Lab questions. The Pre-Lab Questions, Report and Post-Lab questions are due on the date listed. The laboratory data sheet will also be used to assess attendance. If you fail to turn in a data sheet for an experiment, you will automatically receive a grade of zero for that experiment.

 

The Lab Final will be given the week of Feb. 14.  You will be divided into two groups, Group 1 and Group 2, by a random draw.  The subject of the lab final will be announced on eCampus by April 1.  This will be similar to one of the experiments you will have performed during the semester.  You will be required to write up an outline of the experimental procedure you will use listing volumes, masses, indicators, and equipment that will be needed.  On the day you are scheduled for the Lab Final, you will follow your procedure, collect and record the data from the experiment.  You will then calculate a value for your unknown.  You will be graded on your procedure, your laboratory techniques observed during the Lab Final, the recording of the data, and then the calculation of the end result of the experiment.  You must perform the experiment by yourself (NO PARTNERS).
