 Course Pre-requisites, Co-requisites, and/or Other Restrictions

Although students must register for a separate course number for lab and lecture, the two “courses” are in fact the same course and are separated for scheduling and reporting reasons.  Your final grade is derived from the combination of your lecture and laboratory grades.  Together the lecture and laboratory satisfy the state learning objectives (CS1, CT2, CT3, EQS2, and TW1) and therefore must be taken concurrently. 

Concurrent enrollment in CHEM 1112 lab is required.  Prerequisite:  CHEM 1411 or CHEM 1311 and CHEM 1111.

 Course Description – from college catalog

A continuation of CHEM 1411, this second semester course sequence involves the general study of inorganic chemistry including fundamental concepts, thermodynamics, kinetics, chemical equilibrium, descriptive chemistry of the main group and transition metal elements, acids and bases, colligative properties, electrochemistry, and oxidation-reduction reactions.  Organic chemistry is introduced.  This second semester laboratory sequence is designed to provide an introductory level knowledge of the techniques and procedures employed in a first year chemistry laboratory course.  Experiments dealing with inorganic synthesis, qualitative analyses, chemical equilibrium, kinetics, acids/bases/buffers, molecular structure, colligative properties of materials, and solubility product are utilized.

Methods of Evaluation

 Lecture Exams

Five (5) exams will be administered throughout the semester (including final) during the lecture portion of the course.  All exams will be cumulative throughout the course and will consist of multiple choice and short answer questions.  If the final exam is higher than the lowest previous exam grade, it may be used to replace that lowest exam grade. 

One (1) exam will be given at the end of the laboratory portion of the course.  This exam will consist of questions primarily related to laboratory procedures and calculations and may not be replaced by the lecture final. 

There are no makeup exams! If you know you will be unable to take a test during the assigned time, contact me PRIOR to the test to make arrangements to take the test at another time. Decisions concerning alternative testing times are strictly the discretion of the professor.

Students must bring a scantron and scientific calculator to every exam.  Cell phones may not be used as calculators.  If a graphing calculator is used, the memory must be cleared prior to the exam. 

Exam grades will be posted in Canvas.  Students may view their exams after grading, but the instructor will keep all exams and scantrons.

Success in chemistry is strongly linked to completing homework and reading assignments.  Homework problems, in-class work sets will be factored into an overall homework grade, which will be equal to a unit exam grade in value.  CHEM101 quizzes must be completed weekly; typically, by Sunday at 11:59 pm.  Homework assignments will be collected at each unit exam.  Extensions on assignments are at the discretion of the instructor. 

Laboratory reports

Weekly lab report grades will be averaged together and will be equivalent to 2 exam grades

The points allotted to each laboratory report are as follows:

 

Pre-Lab Assignment

10 pts

Actual Lab work

60 pts.

Results (Precision and Accuracy)

Up to30 pts

 

Report Sheets for every experiment are posted in Canvas.  The student is responsible for printing the correct report sheet BEFORE coming to lab.  A 10 % penalty will be issued for not using the correct lab sheet

Pre-Lab Assignments are posted on each lab sheet in Canvas and must be completed BEFORE the beginning of the laboratory period. 

Precision and Accuracy grades will be applied to experiments with quantifiable results. 

Laboratory reports are to be handed in at the end of the scheduled lab period, unless specified otherwise by the instructor.  EACH STUDENT MUST TURN IN HIS/HER OWN INDIVIDUAL REPORT.  A penalty of at 10 points per week will be assessed to lab reports turned in late.  Lab reports will be returned to the student in a timely manner. 

A student must earn an average grade of at least 50% on lab reports to receive a passing grade for CHEM 1312/1112.  If a student’s lab report average is below 50 %, they will receive an F grade for the entire course, regardless of the actual course grade calculated below. 

To determine student’s final grade:

If the final exam grade is greater than any lecture exam grade

  1. Add up points earned on 3 highest scoring lecture exams
  2. Add the final exam grade x 2
  3. Add the points earned on the laboratory final
  4. Add the average points earned on weekly lab reports x 2
  5. Add the percentage of points earned on homework and classwork (points will be posted in Canvas)
  6. Add the percentage of points earned on quizzes (points will be posted in Canvas)
  7. See chart below

If the final exam grade is the lowest exam grade

  1. Add up points earned on all 4 lecture exams
  2. Add the final exam grade
  3. Add the points earned on the laboratory final
  4. Add the average points earned on weekly lab reports x 2
  5. Add the percentage of points earned on homework and classwork (points will be posted in Canvas)
  6. Add the percentage of points earned on quizzes (points will be posted in Canvas)
  7. See chart below

Methods of Instruction

Lecture: Face-to-Face course, 135 minutes/DAY  on campus

Lab: Face-to-Face course involving hands-on experimentation 2.5 hrs/day on campus,

Students will work both individually and in small groups to complete laboratory experiments

Testing conducted on campus in class

 Course & Instructor Policies

Students, who drop the Chemistry 1312 lecture course, must also withdraw from the Chemistry 1112 lab course. 

 Laboratory Safety Policies:

Chemical splash goggles must be worn in the chemistry laboratory anytime chemicals, glassware or heat are used.  NO EXCEPTIONS.  Safety “glasses” are not acceptable.  This includes during lab cleanup or when any group, regardless of location, is still conducting an experiment.  Students will be given only 1 warning during a laboratory period.  If the student is caught without goggles later in the period, they will be dismissed from the lab and receive a grade of 0 for the experiment.

Students are not allowed to wear flip-flops, sandals or open toed shoes in the laboratory.  Shoes must cover the top of the foot.  Students without proper footwear will be sent home to change.  Students will not be given extra time to complete labs due to coming in inappropriate footwear.

It is strongly recommended that students wear long pants or long skirts and refrain from shorts and short skirts.  Laboratory coats and aprons are permitted, but will not be provided.

Students with long hair are encouraged to pull their hair back or put it up.  Loose hair can be a serious hazard. 

Although “accidents” do happen in the laboratory, glassware breakage is generally preventable.  If laboratory equipment is damaged or broken due to carelessness, the student will be charged up to 10 points on the daily lab report grade for each item broken or damaged. 

In order to protect our local water supply, students are required to follow all chemical waste disposal guidelines given by the instructor.  Failure to comply with proper waste disposal will result in a 10 point penalty for each infraction.

Class Attendance

Academic success is closely associated with regular classroom attendance and course participation. Any student missing more than 20% of the class meetings (more than 5 absences) or excessively tardy to lecture or lab (routinely more than 10 minutes late) will have their final class grade lowered by 1 letter grade.  Any student missing more than 50 % of class meetings (14 or more absences) will receive an automatic F grade, regardless of actual earned grade. 

STUDENTS ARE REQUIRED TO ATTEND THE LABORATORY SESSION THEY ARE ENROLLED IN.  If a student must be unavoidably absent from lab, they must secure permission IN ADVANCE from the instructor to make up the lab at another time.  Unexcused absences will receive a grade of 0 for the experiment.  Decisions concerning alternative laboratory times are strictly the discretion of the instructor.

All successful students, whether on campus or online, are expected to be highly self-motivated.

All students are required to participate in courses regularly and are obliged to participate in class activities and complete and submit assignments following their professors’ instructions.  Students taking courses during compressed semester time frames such as mini-mester, summer sessions, and mid-semester should plan to spend significantly more time per week on the course.  Responsibility for work missed because of illness or school business is placed upon the student.  More than two (2) absences are considered to be excessive. In addition, students’ eligibility to receive financial aid or live in a College dormitory can be affected by withdrawal from courses. When withdrawal occurs, any tuition refund would be made in accordance with state regulations.

 Student Conduct & Discipline

All cell phones and other electronic devices must be turned off or to silent before entering the classroom.  Texting during class means you are not paying attention and is unacceptable behavior.  Cell phones may be used during class for legitimate educational purposes (accessing periodic tables or other chemistry apps)

Students may use laptop computers or tablets during class but are expected to be using them for chemistry classwork only.   Students using laptops for other purposes will be asked to turn them off or leave the classroom. 

Student Responsibility

You have already made the decision to go to college; now the follow-up decisions on whether to commit to doing the work could very well determine whether you end up working at a good paying job in a field you enjoy or working at minimum wage for the rest of your life. Education involves a partnership that requires both students and instructors to do their parts. By entering into this partnership, you have a responsibility to show up for class, do the assignments and reading, be engaged and pay attention in class, follow directions, and put your best effort into it. You will get out of your experience here exactly what you put into it – nothing more and nothing less.
