This coursecovers Chapters 11-17, 20, 22, and 23 in the textbook Chemistry, 6th edition by McMurry and Fay, Pearson/Prentiss Hall Publishing. The following are the course requirements:
a.Attendance is required. Blinn College believes that class attendance is essential for student success. Yes, I will take roll. Therefore, students are expected to report promptly and regularly to all their classes. The attendance policy is outlined in section 10b. Please refer to that section for any matter concerning attendance. Remember, you must attend all labs; any absence in the lab counts as one day absence, as well. There has been much discussion about the flu lately. If you think that you have the flu, please notify me, and don’t come to class. However, you need to inform me via email as soon as possible that you are about to miss, or have missed a class.
b. Homework is a requirement. There will be 4 assignments, corresponding to exams 1 through 4, due during this semester, each worth 25 points, for a total 100 points. I will allow you to rework these problems once the exam is taken by you .This will be worth 10% of your grade. The Homework collection and grading will be handled by the Mastering Chemistry system. A code must be purchased in order to access this system. Further instructions are given at the website http://masteringchemistry.com. Homework will be based on the following criteria: (1) Homework is turned in on time, (2) The assignment is complete, and (3) The answers are correct. N.B. The Course ID for this class is GALLEGOS1412SPRING309
c. Exams are a requirement. There will be 4 Lecture exams given on the days indicated in the course schedule; refer to section 11 for the schedule. There will be a 5th Optional Comprehensive exam to be given on the last class day. This exam is meant to be a review exam, meaning that I consider this exam to be a good review for the final. I will give you the key to this exam, along with the worked out solutions in order to help you study for the final exam. You do not have to take the comprehensive 5th exam. However, if you do take the exam, and you score well enough on it, you may replace your lowest exam score from the first 4 exams. In other words, if you take all 5 exams, I will count your top 4 Exam grades. Each exam will be worth 100 points. These exams may have a combination of multiple-choice questions that will be machine-graded and non-multiple-choice questions that will be hand-graded. In fact, in all likelihood, the first three exams will be either work out only exams or exams that are half work out problems and half multiple-choice, fill in the blank, short answer, etc. The last two exams will be multiple-choice only. This is to give you a good idea of how the final exam will be, as the final exam is always multiple-choice. Regular exams amount to 400 points or 40% of the total final grade. Please note:
All exams (and quizzes) are closed-book . No notes may be used on exams. All necessary information will be supplied to the student. Should you miss an exam, you will be allowed to make it up, assuming that you have a valid excuse. However, all make-up exams will be work-out problems only. As well, on all exams, including the final, there will be special rules in order to insure fairness: Please use the restroom before the exam. If you must leave the room for some reason, you must turn in your exam, and you will not be allowed to come back to the room. Thus, restroom breaks are not allowed on an exam or quiz. When taking a quiz or exam, you must place all personal belongings off your desk. You cannot use your cell phone during your exam. If you miss an exam, you must make it up within 5 school days; otherwise you will not be allowed to make it up, regardless of the excuse.
d. Bonus Quizzes are a requirement (But they are a bonus!). Several opportunities will be given during the course of the semester to obtain quiz credit. You will have at least 8 scheduled bonus quizzes, each worth 20 pts. I will take the five highest quiz scores as your quiz grade. All of these quizzes will be individual effort. Remember, these quizzes are Bonus, meaning that the maximum 100 pts will be added to your final grade tally (see Grading Criteria, section 9). You will receive a key to each quiz after you have taken the quiz. If you miss a Bonus Quiz for whatever the reason, you will not be able to make the quiz up (because these are bonus only).
e. Laboratory experiments are required. The laboratory portion of this course counts for 20% or 200 points of this course. For each experiment you will receive a score between 0 and 20 (20 pts max.). The lab report must reflect information obtained by you while in the laboratory and recorded in your lab notebook. The Data Sheet from your lab notebook must be signed by me and the yellow copy must be turned in to me before you leave the lab (5 pts.). (You will keep the original copy). As well, you will need to sign a Lab Attendance Sheet. Lab Reports will not be accepted unless one of these has been completed for the experiment. Lab reports must be turned in individually (i.e., each student must turn in an assignment). The Prelab questions (5 pts) will be due prior to the start of the experiment. There will be 10 experiments in this semester. (Remember, you need to attend all of the classes, including the labs.) All of the 10 experiments that we will perform this semester will count; this will be necessary, since there will be no make-up labs. Each Report with Prelab is worth 20 pts; therefore, the total will be 200 points. So, a typical lab report that you will turn in will have then following sections:
- Prelab (To be turned in before you start the experiment; worth 5 pts.)
- Data Sheet (To be signed by me, your instructor, and a yellow copy from your notebook turned in to me before you leave the lab)
- Postlab (This is the section of the lab report with your calculations and questions that you will answer after you perform the experiment; worth 10 pts.)
So, in summary, the prelab is to be written before you come to lab and to be turned in before you perform an experiment. The data sheet must be completed by you during the lab on laboratory notebook paper found in your laboratory notebook. The postlab is the only thing that you will work on after performing the lab; you will have 14 school days (2 weeks) to turn in your postlab to me.
Students need to form groups of two in order to perform each lab. During the first class day, we will form the lab groups. If any groups of 3 are needed (due to an odd number of students in class), then I shall assign these. There should not be any groups of 4; if people choose to form groups of 4, they will be assigned a grade of zero. You need to attend all the lab sessions, if you miss a lab for any reason, you may obtain a copy of the data sheet from someone in the class or me and you may still turn in to me the postlab, but you will not be allowed to turn in to me the prelab, nor receive credit for the data sheet. Please note, your total lab grade will be out of 200 points. Please note: there have been several complaints of students not cleaning their glassware after experiments. Accordingly, I have decided to start a new policy. From now on, whenever you finish the laboratory experiment, you must clean and dry your glassware and place it on your lab bench. When asking for me to sign and collect your data sheet, you must show me your clean and dried glassware on your lab bench first. If you fail to show me your clean and dried glassware, I will not sign your data sheet, or I will deduct points from the postlab report.
Please note, eating and drinking are not allowed in classrooms or laboratories. This is especially true in the laboratories. You need to put away or throw away any food/drink before you enter the lecture room/laboratory.
For the moment , you will have 10 Lab experiments:
Experment date performed/date due
21 1/29 2/12
22 2/07 2/21
23 2/19 3/05
24 2/26 3/21
25 2/28 3/21
26 3/07 3/28
27 3/21 4/04
28 3/28 4/11
29 4/04 4/18
30 4/11 4/25
No postlab report will be accepted by your instructor if it is late.
f.Participation Grade. Blinn has now has added a participation grade to its core classes. Accordingly, this grade will be comprised of quizzes, called lecture quizzes. I anticipate that there will be at least 12 of these this semester, of which I will count the top ten. These quizzes will be handled by the mastering chemistry homework system. You will be able to access these quizzes just like you will access the homework. I will alert you when you may access these quizzes. The sum total of these quizzes will be 50 points; each is worth 5 points. The second part of the participation grade will be due to lab quizzes. There will be three lab quizzes scheduled during the semester, each of which is worth 25 points. I will take the top two, for a total of 50 points. The first lab quiz will be on Experiments 21-23. The second lab quiz will be on Experiments 24-26. The third will be on Experiments 27-30. The schedule for these quizzes will be updated later in the semester. The total participation grade is 10% of the total final grade or 100 points total (50 points from the lecture quizzes and 50 from the two lab quizzes).
g. Exam and major assignment calendar:
Please note, you will have 5 exams and 4 homework assignments during the course of the semester. For the first 4 exams, your exam dates are the same as the due dates for the homework assignments. The fifth exam is the comprehensive optional 5th exam.
Due Date Exam number Homework assignment due
Tues 2/05 EXAM I on Chapters 11/12 Assignment 1
Tues 3/05 EXAM II on Chapters 13/14/15 Assignment 2
Tues 4/02 EXAM III on Chapters 16/17 Assignment 3
Thur 4/25 EXAM IV on Chapters 20/22/23 Assignment 4
Tues 4/30 Exam V comprehensive optional
h. Final Exam. The final exam for this class will be comprehensive, all multiple-choice (a, b, c, d,e), and worth 200 points, or 20% of the grade, and last 2 hours, all of this in accordance with Blinn College Policy. The final exam for all 1412 will be a common final exam on Saturday, 4 May, 2013 from 1:00 p.m. to 3:00 p.m. in a yet-to- be determined place, although it will most likely be in the Science Building.
i. Make-up work . Because of the nature of the course, make-up work can only be allowed for missed (a) exams, and b) lab quizzes. No other type of work will allowed make-up work. Of course, the only way that exams and lab quizzes will be allowed as make-up work is with the proper excused absence paperwork.
Grading Criteria/Final Course Grade for this course is as follows:
Exams (5 total, drop 1) 400 pts 40%
Homework 100 pts 10%
Lab Experiments 200 pts 20%
Participation Grade 100 pts 10%
Final Exam 200 pts 20%
Bonus Quizzes (max. 100 pts) Bonus
TOTAL 1100 pts out of 1000 points max
The range of each letter grade will be assigned at the end of the semester. Based on prior grade assignments, typical grade ranges are:
Total Course Points greater than or equal to 900 = A
Total Course Points greater than or equal to 800 but lower than 900 = B
Total Course Points greater than or equal to 700 but lower than 800 = C
Total Course Points greater than or equal to 600 but lower than 700 = D
Total Course Points less than 600 = F
It is impossible to tell if there will be a curve for this class; hence, we will look at the grades at the end of the semester to see if one were to be warranted.
Blinn College Policies
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:
- 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);
- representing the College District at an official institutional function;
- high school dual credit students representing the independent school district at an official institutional function; and
- 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.
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.
