Course Overview
In this course you will learn about some of the important
topics in chemistry. We will start with some essential math
skills and use these to cover such topics as density, atomic
structure, the nature of light, nuclear chemistry, molecular
structure, and chemical reactions. We will always endeavor to
make the work applicable to everyday life.
What to Bring to Class
- basic scientific calculator
- lab notebook (for lab days)
Grading
The grading policy of Chemistry 3 is designed to reflect how
much work you put into learning. If you put in the effort to
learn the material you will do well. Your grade will be based on
the following categories.
- 15% - Classwork, homework group work, etc. Checked off in
class. Homework will accompany each unit.
- 35% - Labs: working in the lab is essential to understanding
chemical theory; writing about what you learned is also
essential
- 20% - Quizzes: these will be frequent and short
- 30% - Tests: usually two or more comprehensive tests per
quarter
Make-up Work
If you miss class, and it is an excused absence, then you may
make up the work you missed. You must see me before class starts
or after it has ended and ask for the work. It is your
responsibility to find out what you missed and to do it. You must
complete the work no later than the due date plus the number of
days absent or the usual late penalties will apply.
Late Work
Lateness is not acceptable unless you were absent and have
shown me proper documentation to prove your absence was excused.
Arrangements to hand in work missed when absent must be made at
the first class meeting upon your return. Late work is subject
to a penalty of 25 points on a 100 point assignment. Late
work will be accepted only within two days of the original due
date. After that it will not be accepted. Incomplete work handed
in on time will not be eligible for do-overs. Incomplete work
handed in late will not be accepted.
Lab Safety
Safety is of paramount importance in the lab. Warnings of
particular hazards will be given in the introduction to each lab
activity. Students will be reminded once of safety rules.
Students who do not heed such reminders will have to sit out the
lab and take a zero.
Resources for Extra Help
I am available before and after school most days to provide
help with your work. I arrive around 7 am and will usually be here
until at least 2:30 pm. If you are struggling make
an effort to come and see me. In my experience this one action
can improve your understanding (and your grades) immensely.
Recitation
Once a week I will hold a Chemistry-3 Recitation session.
Students may attend at will and will receive two points toward
the next quiz for each session they attend. Times and days will
be determined but will usually be Tuesdays at 1:45 pm. Recitations last one hour.
Points will be given for attendance and participation: come
prepared with questions and problems you are having trouble
with.
