					The images shown above represent the evolution of chemistry. For example, on the
left the four recognized elements were fire, air, earth, and water but it turned out that
none were elements. We now recognize 114 elements, with my favorite being
element 111 called unununium. The other images also has their stories, which we
will discuss in class.
Welcome to the Fundamentals of Chemistry.
Dividing a chemistry topic into three areas of
focus makes it easier to understand.
The building blocks focus sees chemicals
coming from simpler building blocks.
Chemistry also involves force and energy.
Attraction and repulsion of + & - charges
guide the assembly of atoms and chemicals.
The third part of chemistry involves
mathematics. The Earth represents the
Metric system which is based on Earth
measurements and water.


                                    Chemistry is a vast subject, more than you or I could ever
                                    know, but fortunately learning the fundamentals of chemistry
                                    is possible. One fundamental of chemistry is understanding
                                    the electrons, neutrons, and protons that make up atoms.
                                    It’s amazing that everything you can see or touch is made
                                    from these three tiny particles. However, their microscopic
                                    world is very bizarre, similar but stranger than Hollywood’s
                                    virtual world called the Matrix. After learning chemistry you
                                    will look at the world differently just as Neo did in the movie.
                                   To the left is the textbook. I do not
                                   follow it too closely, but it is a good
                                   textbook that could supplement my
                                   lectures. I cover additional material not
                                   in the textbook. There exists a study
                                   guide and solutions manual,
                                   but I don’t require them.
                                   The textbook may or may not
                                   come with a CD-ROM. It doesn’t
                                   matter if you get it or not.
                                      You will also need a scientific
                                      calculator. Not right away but

                                                      Learning




1. Gain an appreciation of chemistry: its value to society, its role in history, the effort to get this far, the modern
   marvels.
2. Learn about chemistry’s building blocks from light  matter/antimatter  protons + electrons + neutrons 
   atoms  compounds  organic vs. inorganic  small compounds (CH4, CO2, H2O, SiO2)  large
   compounds (sugars, amino acids, hydrocarbons)  macromolecules (starch, cellulose, proteins, DNA)
3. Learn how to approach a chemistry topic as a blend of bluilding blocks, force & energy, and mathematics.
4. Learn the fundamental behaviors of atoms: Electrostatic forces, the bizarre world of quantum physics,
   chemical bonding, and the periodic behaviors indicated in the Periodic Table.
5. Smarter consumer of chemical products: Better understanding of labels, smarter at reading past the hype or
   paranoia, and better at recognizing pseudoscience.
6. Improved chance of survival: Knowledge of neutralizing acids/bases, better avoidance of chemical dangers,
   better at improvising, better at solving problems, and better at critical thinking.
                                        Below is the planned schedule; however, unexpected events may change the
                                        schedule. Changes announced in class will override this schedule.

  May 3      To Be Announced

             Review for Final
  May 5

             Final Exam this week
May 9 - 12   Grades turned in
If you have any special learning needs, let me know, but first visit our Disabilities Resources &
Services Office. They will work with both you and me to find ways to help. Deaf students will enjoy
the many visuals I use in class. Visually impaired students with some vision can get my
PowerPoints so they can view them in the library’s Adaptive Lab. Totally blind students will have a
bigger challenge, but I am willing to try some alternatives.




No one likes tests, even teachers. In the old days, when people learned by
apprenticeship, there wasn’t a need for tests because the master knew how the
apprentice was doing by watching them and regularly asking them questions.
However, in a classroom of 40 students, the instructor may have know idea
how much a student has learned, so a test is one way of finding out.
One philosophy of teaching is that instructors are only sure that they have taught
the subject if they find out that students have learned the subject. In other
words, I must ask you a lot of questions to see if I’m both you and I are doing a
good job.


My expectation is that everyone understands everything on the test and gets it
100% right. Everyone may not get it 100% the first time, but they should get it
correct on the 2nd, or 3rd time. It makes no sense to go on when there is
something critical missing. Much of chemistry builds off the previous material.
Of course, a person who takes three tries to get a question right doesn’t
deserve the same amount of credit of the person who got it right the first time.
But getting it right the third time still deserves credit.
On problems you missed, you have the opportunity to be retested with a similar
problem. You get 90% of the score you would have gotten if you got it right the
first time. Each time you have to redo it will cost another 10%. For example, if
you miss a 10 point question but get a similar one correct on the retest, you
make 9 points, which is much better than losing all 10 points. You just have to
make an extra effort to do it again. In short, I’m more interested in you learning
the material than giving you low grades. I’m not eager to do extra grading, but
I’m willing to do that if you are willing to put in the time to restudy and retest on
what you missed. Final grades are not based on a curve, so students who ace
a test the first time shouldn’t worry about the students who retake the test to
improve their scores.
I really hate to talk about points for two reasons First it takes your attention away from the subject.
Second, it implies that grading is accurate down to the last little point. It would be hard to prove that a
person with 524 points actually knows more than someone with 523 points. Mathematically it seems
accurate, but in actuality grading is approximate. When a teacher says one question is worth 15
points and another is worth 10 points, the choice is rather arbitrary.
With this said, we can use points because it is easy to work with, but it is only approximate.
People who focus only on learning the subject do better than those who worry about grades. That’s
because when you worry about points and grades, you are not thinking about the subject. Listen and
learn in class and grades will take care of themselves.
In case you are still interested, here is the breakdown of points that will serve as a guide to your grade
Attendance: 100 points
3 tests: 100 points each totaling 300 points
Final test: 100 points
Poster project: 100 points
Miscellaneous assignments: 100 points

Total: 700 points
Grades are 90-100%=A, 80-89%=B, 70-79%=C, 60-69%=D, Below 60%=F
If your points are close to a better grade, I will always give you the benefit of the doubt and give you the
better grade because, like I said, grading is not that accurate.
Notice attendance is a big contributor to your grade. I figure that every time you come to class, you
demonstrate a willingness to learn and will probably learn something that day, so you deserve credit.
Perfect attendance will be like getting a perfect grade on a test.
I again apologize for this much attention drawn to tests and points. Being aware of them is good, but
worrying or being fixated on them will actually take attention away from learning and hurt your grade.
The best thing is to get interested in the subject and that motivation will help you do good on any tests
that come your way.


Just like I expect everyone to learn the material well enough to get an A, I also
expect everyone to finish the class. However, if you miss three classes in a row
without contacting me, I will telephone you and send email to find out what’s
going on. Note I can be pretty flexible when you have circumstances that
warrant it. But if I can’t get a hold of you, I will have to withdraw you from class.
If you disappear a week before class ends, I may just give you a grade based on
your work up to that time, but lowered because you missed the final.
The images shown above represent the evolution of chemistry. For example, on the
left the four recognized elements were fire, air, earth, and water but it turned out that
none were elements. We now recognize 114 elements, with my favorite being
element 111 called unununium. The other images also has their stories, which we
will discuss in class.
Welcome to the Fundamentals of Chemistry.
Dividing a chemistry topic into three areas of
focus makes it easier to understand.
The building blocks focus sees chemicals
coming from simpler building blocks.
Chemistry also involves force and energy.
Attraction and repulsion of + & - charges
guide the assembly of atoms and chemicals.
The third part of chemistry involves
mathematics. The Earth represents the
Metric system which is based on Earth
measurements and water.


                                    Chemistry is a vast subject, more than you or I could ever
                                    know, but fortunately learning the fundamentals of chemistry
                                    is possible. One fundamental of chemistry is understanding
                                    the electrons, neutrons, and protons that make up atoms.
                                    It’s amazing that everything you can see or touch is made
                                    from these three tiny particles. However, their microscopic
                                    world is very bizarre, similar but stranger than Hollywood’s
                                    virtual world called the Matrix. After learning chemistry you
                                    will look at the world differently just as Neo did in the movie.
