Disclosure Document for Chemistry
Ms. DelMar (2009-2010)
Will it explode? Why is there air? Why aren’t all substances solids (or liquids, or gases) at room
temperature? Is it safe to store radioactive waste in Utah? Will cars fueled by hydrogen save the
environment and save us from our dependence on foreign oil? How are medicines discovered,
designed or made? Could you make a self-cleaning window? Chemistry can help you answer all
of these questions and many more.
Chemistry is designed to provide students with an understanding of how matter behaves
at the macroscopic and molecular level. Students will be exposed to the relevance of
chemistry in the everyday world. Much emphasis will also be placed on how to approach,
analyze and solve problems. Competence in algebra is assumed for Chemistry students.
I expect each student to: be present, prepared, and on time; be responsible for their own
learning and growth; complete all work to the best of their ability; be patient as they
master new material; and to be successful, if assignments are completed consistently.
Students should expect me to: be present, prepared, and on time; present material in an
organized and enthusiastic manner; help them become better problem solvers; and grade
all activities fairly and in a timely manner (3 days).
I expect students to bring their books (and a calculator, when appropriate) to class,
to have their homework ready to hand in as we start class (with your name and the
assignment # already on it), and to have their book open and ready if they want to
ask a question at the beginning of class.
Homework/Class participation/Quizzes 30 %
Lab Reports 30 %
Chapter Tests (3 each trimester) 20 %
Trimester Final 20 %
Chemistry is an experimental science. It’s more entertaining and informative to see and
experience chemistry than to listen to a lecture. Therefore, one period each week will be
spent in the laboratory performing experiments that illuminate the concepts covered in
class. Laboratory experiments and reports will be kept in a bound laboratory book
provided. Students will learn and practice proper safety procedures in the lab. Labs are
chosen to minimize contact with toxic or dangerous chemicals as long as proper safety
procedures are followed.
Note: Homework assignments and class notes are on the website and on the
syllabus attached to this disclosure statement. Homework assignments are also
written on the board each day. (Dates may sometimes change slightly on the
assignments, so check the website for current info.)
Chemistry can be a difficult subject and is best learned through practice, so timely
completion of the homework assignments and lab reports is essential to success in this
class. Homework will be assigned almost every day and is due at the beginning of the
next class period (or at the end of your “consultation days” if you have been absent). If
you are present in school for part of the day, your chemistry homework is due that
day, even if you miss my class. I will accept late assignments with a loss of 10% of the
points each day. There are no unexcused exceptions to this rule. If you have exceptional
circumstances, I will be happy to work with you: come to me with a plan. Assigned
essay questions should be answered in complete sentences and all work shown on
quantitative problems. Bonus problems are identified for each chapter and are due as
announced in class. Homework may be submitted in class, in my mailbox in the office, or
in the boxes in the back of the room. Please do not disturb class to hand me your
homework! Your attitude and participation in class are important and may positively
affect your grade if you’re “on the edge”. Studying with friends or in study groups is
encouraged, but identical homework assignments or lab reports will receive a zero.
When working in a group, each participant should have their brain and calculator
Redo policy: Homework assignments on which you have scored an 8 or below may be
redone for full credit if they were originally submitted on time. (Late assignments are
marked with a “.1” after the score and may NOT be redone.) Redos must be submitted
within 2 days of return of the paper. Redo scores are entered with a “.01” after the score.
Assignment numbers are critical on late or redone work. One point will be deducted
for missing assignment numbers. One test a trimester may be redone to recover one
third of the points lost. For the redo, use a new sheet of paper, redo all missed
calculations, redo multiple choice by giving the correct answer and explaining why that
answer is correct. Labs may not be redone, so take time to do them well.
Note: Computer or printer failure is not an acceptable excuse for missing or late
homework. “All students have been supplied an external hard-drive for backing up
computers and files. It is your responsibility to back up your work for class.” (quoted
from the Student Handbook) Print your assignments out well in advance of class.
We will have three tests per trimester and a cumulative (for the trimester) final. The tests
take the entire period allowed, are designed to be challenging, and I generally aim for a
Excused Absences and Consultation Days
Daily class notes and assignments will be available on the Chemistry website to help you
stay current with missed material.
Please read the Consultation Policy that covers excused absences in the Handbook. I will
usually be in my room (or lab) for consultations on Tues/Thurs during the morning break.
This consultation is NOT time for me to teach the lesson you missed, so read the missed
notes and book sections before you come to ask questions. It is instead time for you to
show me the work you have done and ask me specific questions to help you complete
your assignment. Consultation can be made in person or by email. (If I don’t respond to
your email within 24 hours, I did not get it and you need to follow-up on your request.)
“Students, faculty, staff, and administration must read and respond to email at least twice
daily. Not knowing about an assignment or responsibility sent by email is not an
acceptable excuse. Users should check their email in the morning and before leaving
campus for the day.” (From the Student Handbook)
If you are absent, check the website (web.mac.com/jdelmarrhsm) for the assignment
you missed. This is particularly important if you are going to return on a lab day since
you will need to have the pre-lab done to be able to participate in the lab.
A calculator that will allow you to do logarithms is required. You will also need
scissors and tape for lab reports and highlighters, post-its and a clear ruler for underlining
important information in active reading. A separate notebook for chemistry notes is
encouraged but not required. Bring a pen or pencil to class to take notes.
Course Work: Introductory Chemistry: A Foundation by Stephan S. Zumdahl
Laboratory Text: None; experiments will be drawn from many sources and provided as a
handout each week.
Additional Lecture material and sample problems will come principally from Chemistry:
Connections to Our Changing World by LeMay, Beall, Robblee and Brower. This book
presents many of the concepts covered in a somewhat different, and often more detailed,
form. Copies of this book are available on loan if you’re having trouble with a
Questions or Help
Questions about homework assignments are covered in the first few minutes of each
class. If you have other questions or need extra help with the material (and many people
do!), I’ll be happy to schedule a time to meet with you. I have 1st and 7th periods free. I
can be reached by phone at 801-487-4537 (until 9 pm) or by email at
email@example.com. (email is better) On-line tutoring, practice quizzes, and
additional help is also available at the student website (described in the student support
package provided with the book).
Experiments will be described in a handout provided each week. These handouts will be
used to prepare lab reports (which are described in a separate handout).
Tardies: If you are not in class when the bell rings you will be sent to the office to
obtain a green admit slip. No exceptions. As tardies accumulate you will be given
detentions per the school’s policy.
Dress: The RHSM dress code will be enforced in class. That means no pajamas or
clothes that are too short or revealing. You will be given one warning and then will be
given a detention.
Food and Drink: No food is allowed during class times, excepting class events.
Beverages are allowed within acceptable limits.
Laptops – You may not use laptops in the classroom unless you have been specifically
instructed to do so. (Talk to me if you want to take class notes with your laptop.) Misuse
of the laptop in class will result in a detention or worse depending on the infraction
Cell Phones/Other Devices – If any device becomes a disruption in class it will be
confiscated for the rest of the day.
