General Course Description

Principles of Chemistry is a study of fundamental chemical concepts:  scientific measurements, matter and energy, stoichiometry, atomic structure, the periodic table, chemical bonding, gases and liquids.  The course is designed primarily for students with a concentration in biological or physical sciences and for students interested in transfer to a four-year program in engineering.  A three-hour lab session is required each week.

Prerequisites: English Composition I (ENG101) Eligible; Pre-Calculus (MAT103) Corequisite; General Science (SCI 099) or Placement.

PREMED/NURSING STUDENTS PLEASE NOTE:  This course is intended for students planning to transfer as science majors. This includes students who are considering being PREMED when transferring to four year colleges and universities.   Nursing/Health Careers students planning on applying to Nursing School or other allied health programs should take SCI121 not this course. 

 Principles of Chemistry I and II and Lab (SCI123 and SCI124), fulfills the chemistry requirement of biology, pharmacy, premed, prevet, engineering, or chemistry majors.  It is expected that the student will go on to the second semester of this sequence Principles of Chemistry II (SCI124) or equivalent; SCI123 is not designed to be a one semester introductory course.  This course is generally viewed as a science major introductory chemistry class.  If your intended program of study is a physical science, pharmacy, pre-med/pre-vet, or engineering major this course is required.  Laboratory work serves to reinforce concepts as well as introduce students to the scientific method, basic laboratory techniques, and the importance of safety in the laboratory environment.

Students in most allied health programs and non-science majors filling a science elective should enroll in General Chemistry I (SCI121).  The SCI123 course is not designed to be a one-semester overview of general and inorganic chemistry but is the first semester of a two -semester sequence for science and engineering majors.  If there are questions regarding whether you need SCI121 or SCI123 for your program of study, discuss this matter with the instructor or your academic advisor.

Student Commitment and Tips

The study of general chemistry for science, pharmacy, engineering and pre-med/pre-vet majors is challenging but not impossible.  In order to be successful in this course you will need to be aware of the following:

The course material is defined by the course content of previous SCI123 courses and the content of the science major general chemistry courses at other institutions.  As a result there is a lot of material to be covered in one semester (15 weeks) and in general the material builds on concepts developed earlier in the semester.  As a result it is your responsibility to keep up with reading, lectures and homework.  Especially in a course which relies on earlier concepts to explain newer, more complex ideas it is imperative that you pace yourself accordingly.  You will find a good way to perform poorly in this course is to wait until just before the next quiz or exam and “cram” your studying into a short (sometimes caffeine enhanced) burst of intensive effort.

You will need some math skills in order to be successful in this course.  Intermediate Algebra (MAT 099) or its equivalent is a prerequisite for this course.  You will be expected to understand scientific notation and the use of logarithms and exponents.  You should have a calculator which can display in scientific notation and perform logarithm functions.  How you approach a problem logically and set-up the solution is more important than the numerical answer.  When you approach problems, try to think and execute the solutions clearly.  Use common sense in your problem solving -- is the number on your calculator display one that makes sense?  There should be no shortage of paper for this class so set out your answers so both you and I can follow them.

Expect to read the chapter several times as well as review your lecture notes before attempting the homework problems.  In general a high level of effort expended on solving homework problems will lead to a greater probability of success in examinations and quizzes.  It is very easy to deceive yourself into a false sense of confidence regarding homework problems if you look at the problem and then follow a written solution or flip constantly into the chapter to refresh yourself on the important points.  You will be much better off to reread the chapter and attempt the homework problems without looking at the text or answer solutions.  Failure to discipline yourself in this activity will lead to poor performance on exams and quizzes as well as the laboratory sessions.

More Study Tips:

It is your responsibility to keep up with the class pace, to understand the reading and the lectures and especially to do the homework.  Do not hesitate to ask questions during the lecture and laboratory sessions in order to be sure you understand the material.  The chances are that if something is not clear to you, it is also not clear to many of the other students.  To be successful in this course you will need to plan to spend at least 10-15 hours per week working on your assignments NOT including class and laboratory time.  If you are not willing or unable to meet this commitment, it is recommended that you not take this course at this time.  Due to the rigid scheduling there will be no opportunity to make up missed work.

Teaching Procedure

The lecture portion of the course will be an informal discussion of the course topics.  Questions are encouraged during the discussion and the solution to selected problems is presented and analyzed.  In additionl group exercises will be assigned modeled after research in teaching and learning to help everyone with a deeper understanding of fundamental concepts of the course.  For details on these in class exercises please go to www.pogil.org. Homework assignments will be issued with a due date normally one week after being assigned.  Quizzes will be administered throughout the semester normally on the next class session after a chapter has been completed.  The laboratory portion of the course will generally consist of a short discussion by the instructor followed by hands-on experimentation by the student and the generation of a written report after the experiment.
