Lectures: During the lectures we will discuss the major concepts, and practice calculations relevant to a particular chapter. The most difficult sections of a particular chapter will be emphasized, but 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 and to cover at least one chapter per week. Feel free to ask questions relevant to discussed material.
Quizzes: Quizzes will be given on each chapter. You must be present at the time the quiz starts in order to take the quiz. The best 10 quiz grades will be kept.
Lab Quiz: One quiz covering questions on chemistry concepts and calculations involved in the experiments, as well as laboratory safety and techniques, will be given during the semester. This quiz will be worth 50 points.
Exams: Exams will cover material in the textbook, handouts, lecture, and homework problems. There will be five major exams worth 80 points each. Each exam will cover two or three chapters. All exams are closed notes/books format. Periodic table will be provided. The exams will be composed multiple-choice questions. Only the type of calculator listed in Textbooks and Other Materials will be allowed. All cell phones must be turned off and stowed during the exam. The final exam will be comprehensive and all multiple-choice worth 200 points. Exams missed without prior notification of the instructor will be given a grade of zero. This means you must email the instructor before the exam takes place.
Homework: The 5onlinehomework assignments will coincide with the 5 regularly scheduled exams and are due 11:55 pm the night of the exam. Homework will be graded based on completion of assignment (questions required for the mastery of the material). The Mastering Chemistry online tutorial and homework, a companion to your textbook will handle homework collection and grading. Further instructions are given at the website: www.masteringchemistry.com. Those purchasing used books will need to purchase access online at the above URL. Mastering Chemistry coaches students on problem-solving techniques. Be ready to spend a significant amount of the time on homework. 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 your access to homework would be cut off by the system. Homework collection and grading will be handled by the system. Instructions are given at the website: www.masteringchemistry.com. If you fail to submit your homework, you will receive a grade of zero. Failure to do a required homework can cost you one letter grade.
Lab: The lab work consists of selected experiments, which are integrated with the material being presented in our course. Each lab activity is worth 15 points; 3 points will be given for the Pre-Lab, 2 points for a signed copy of the Data Sheet turned in before leaving lab upon completion of the experiment, and 10 points for each Lab Report, which includes In-Lab Guidelines, Post-Lab Report, and Post-Lab Questions.
Pre-Lab Questions must be turned in at the start of the class period of the day of the experiment(simply put it on my desk as you enter the class), no later than 5 minutes after the beginning of class period, to receive full credit. Lab Material turned in after that time would receive a late penalty (50%). 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 so that you can efficiently collect and record the data needed for each part of the experiment. Turn in the duplicate pages of your observations and data before you leave the lab to determine your presence and give you credit for the lab.
Reports (In-Lab Guidelines, Post-Lab Report, and Post-Lab Questions, all pages in order, and stapled together) are due two class periods after the experiment is completed. If you missed a lab, or forgot to bring goggles or close-toe shoes, wear the appropriate attire, or turn in the data, you will lose points for this assignment. If you missed a lab (excused or unexcused absence) you can only turn in Pre-Lab and Post-Lab Questions (if they are not directly related to the performed experiment) for grading. To receive the full credit for a lab, your physical presence in the lab is required. Neatness and completeness of your data and answers may be 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.
Guide to Answering Post Lab Questions:
Most post lab questions are designed to test your understanding of the experiment and the calculations.
When a question asks what happens to the results, it is asking about the final, calculated results or answer, not the data. However in order to answer the question about the results you must first consider what happens to the data and explain that.
If the question is about the (calculated) result, then first explain what goes wrong with the measurement; then describe whether this makes the final answer too high or too low, etc. To receive credit for the answer, you must explain why. Simply putting “too High” or “too Low” will not receive any points.
Answering by saying “you must repeat the experiment” or “the data are off” will receive zero points.
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.
Computer Use: You are expected to use the computer to access Mastering Chemistry for this course. Computers are available in the Learning Center and in the Open Computer Labs.
Student E-mail Accounts: All Blinn students have a Blinn email account assigned during registration. You should use it regularly for your class announcements. All of your official communication from the College will be via that method.
Final Exam: This exam is a comprehensive exam (covers the entire semester). It is worth 200 points and you will have two hours for its completion.
5 Major Exams (80 pts each) = 400 points
10 Quizzes (10 pts each) = 100 points

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, www.blinn.edu/student%20handbook.pdf.
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:
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.
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, www.blinn.edu/student%20handbook.pdf. In a case of scholastic dishonesty, it is critical that written documentation be maintained at each level throughout the process.
All assigned work is expected to be turned in on time. Late work may be turned in at the next class meeting for a maximum of 50% of the points or a week late for 25% of the points. Assignments more than a week late will not be graded and will be given an automatic 0.
Lab Safety Protection Policy:
Students are required to wear clothing that covers the skin from the neck to below the knees (shirts must have sleeves) or lab coat. Closed toe shoes and appropriate safety eyewear must be worn at all times during lab procedures. Failure to do so will result in expulsion from that laboratory experience. Students are responsible for purchasing appropriate eye protection and wearing eye protection during lab. Appropriate eye protection will be:
1. Chemical vapor resistant safety goggles (required for contact lenses)
2. OSHA approved safety glasses with side shields
No ‘loaners’ are available.
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, 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). As instructor I will protect my student’s investment by removing the obstacles to the learning environment.
During exams special rules are in effect to insure fairness. 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). 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. Violation of these rules would result in grade zero for the exam. Blinn College does not tolerate cheating, plagiarism or other acts of dishonesty.
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. Students are responsible for purchasing appropriate eye protection: safety goggles (required for contact lenses), or OSHA approved safety glasses with side shields). The students must wear approved eye protection, close-toe shoes, and the clothing that covers skin neck to below the knees, shirts with sleeves, or the lab coat during the whole time of the experiment. Failure to do so will result in expulsion from the laboratory for the performed experiment and will automatically result in grade zero for this lab. 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 and equipment before leaving the lab. Failure to clean up your lab area and equipment will result in loss of points (50%).
There will be no makeup assignments except in case of excused absences. 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 may be different than the regular class exam. There is no makeup for the missed labs (see the lab section).
Every student should feel free to visit me in my office for my help and assistance. If you feel 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).
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@example.com.
**It is likely that there will be several revisions to this tentative schedule as the semester progresses.**
