Expectations
I expect you to follow what I call the 4 P’s:
1. Be Prompt (Come to class and hand work in on time.)
2. Be Prepared (Bring materials and finish assigned work.)
3. Be Polite (Be respectful to others and clean up your lab area.)
4. Participate (Do your work with class time provided, take notes, and
answer questions.)
Remember: Chemistry = Chem is try !!!
Classroom Policies
A. Attendance: If a student is truant three times during a term, the student
loses credit for this class. If absent of a test day, the student will take the
test the next day back in class and make up whatever was missed in class
that day. If truant, you will not receive any credit for what was missed.
B. Tardy policy: If tardy, students will hand copy a page from their textbook
each time they are tardy or nothing will be graded until completed.
C. Make-up/late work: All unit assignments are due for full credit on the day
of the unit test.
a. Assignments turned in after the test date will only be worth 50%
credit.
b. Assignments turned in from a previous unit after the following unit
test will not be accepted.
D. Cheating: Any students caught cheating will automatically receive a
grade of zero for the work plagiarized. See Academic Dishonesty on the
next page.
E. Skills Tests: Skills Tests make sure that students have mastered a certain
skill needed for chemistry. In order to receive credit, a student must
receive a certain percentage (85%) or the grade will stay zero until it is
achieved. Students get three tries on all skills tests or get the score of
their 3rd skills test.
F. Lab Work: Students are reminded that doing work is a privilege not to be
taken lightly. Students must agree to follow all written laboratory rules as
well as rules stated by the teacher. Failure to do so would mean loss of
lab privileges.
G. Test Corrections
a. Test corrections can be made to any unit test before the next unit
test date if:
i. the test review was completely finished with quality work
and turned in before the test;
ii. all unit skills tests have been passed.
b. Each question corrected with work shown will be worth 1/3 points.
H. Cell phones/ipod/mP3 player use will not be tolerated (even as a
calculator). If I see a cell phone, I will take it! The cell phone will be taken
to your House office.

Getting extra help: I am usually available before and after school in case
you run into some trouble. Chemistry is a difficult subject, but with some
hard work you have the ability to do well in the course! Just remember to
talk to me to check my availability!

Academic Dishonesty
Academic dishonesty is any activity that involves a student attempting to
receive a grade by any means other than honest effort. Students are
reminded that cheating will not be tolerated. Representation of anyone
else’s work as your own will result in an F and the parent will be notified.
If you are a member of National Honor Society, the cheating will be
reported to the NHS Faculty Council, and this generally results in
dismissal from that organization. The following are examples of academic
dishonesty:
1. A student knowingly procuring, providing, or accepting any materials
that contain questions or answers to any examination or assignment to
be given at a subsequent time.
2. A student completing, in part or in total, any examination or assignment
for another student.
3. A student allowing another student to complete, in part or in total, any
examination or assignment.
4. A student plagiarizing from any source including the internet, or
copying the work of another person, and submitting the work for
evaluation as his or her own.
5. A student using unauthorized aids in completing and submitting an
assignment or exam, i.e. a cell phone, pager, downloaded programs on
a calculator, etc..
6. A student altering a graded exam or assignment without proper
authorization to do so and then submitting the assignment for regrading.

Safety Procedures in Secondary School Science Classrooms
1. Written and verbal instructions concerning procedures and/or precautions are given for
my protection. I will read and listen carefully, and follow all directions. I will only use the
quantity of chemical I am directed to use by the lab instructions.
2. Experiments done in class are for instruction. They are planned in order to teach an
idea. I will perform only authorized experiments. I will never work alone in the science
laboratory.
3. I will handle only those chemicals or equipment for which I have received training. No
control for gas, air, or water is to be turned on except for lab work. Electrical outlets are
only to be used for electrical plug-ins; other inserts are dangerous.
4. Tasting, smelling, or mixing unknown substances can be very dangerous. I will not do so
unless instructed to do so in a planned, approved experiment, with proper techniques.
5. Chemicals are labeled to identify them. I will always carefully read the label (read it
twice) to be sure I am using the correct substance.
6. To avoid contaminating chemicals, never return used or unused chemicals to the
original container. Dispose of leftover and used chemicals as described by the lab
procedure or your instructor.
7. Dropper bottles are frequently used in the chem lab. NEVER touch the tip of the dropper
to the sides of a test tubes or other glassware. NEVER touch the tip of the dropper to
other chemical solutions. This will avoid contamination.
8. No more than one chemical container should be uncapped at a time. I will always screw
the cap back on a bottle immediately after using it. This will prevent spilling or
contamination of the chemical as well as stop the escape of volatile liquids from the
container.
9. I will dispose of chemicals as my teacher directs and never mix chemicals in the sink
drain. To avoid mixing chemicals in the sink drain, pour one chemical down the drain,
flush down with large amounts of running water and then safely pour the second
chemical down the drain, again flushing with water.
10. Horseplay and practical jokes in the science classroom are dangerous and can be
expensive. I will practice safe conduct in the classroom.
11. Fire is dangerous and care must be taken when working with it. I will not reach across a
flame or bring a flammable substance near flames. I will confine long hair and loose
clothing to prevent it from igniting. While working in lab, you or your lab partner must
always stay near a lit burner. I know where the fire extinguisher is located and how to
use it. I will not carry any lighted splints away from the lab station.
12. All fire must be extinguished, gas off, and materials capped before departing from the
classroom for a fire drill or other school activity.
13. Safety equipment (eyewash, shower, first-aid kit) is provided in the science classroom in
case of emergency. I know how and when to use this equipment.
14. Hot materials, such as glassware, hot plates, burners, and chemicals can cause serious
burns. I will be extremely careful when working with these to prevent injury to others
and myself. Important to note: hot glass and cold glass look exactly the same! 
15. I will be sure the open end of a test tube points away from anyone while the test tube is
being heated or shaken. I will always heat test tubes evenly to prevent liquid from
“shooting.” Test tubes heated directly in a burner flame should be removed

immediately if they begin to boil. Test tubes should always be viewed from the side, not
from above.
Broken glass is dangerous. I will use a broom and dustpan to immediately pick up all
broken glass and place it in the broken glass container. If broken glass is in the sink, I will
use forceps to pick the pieces out of the sink and place them in a dustpan to carry them
to broken glass container.
Safety goggles are required by law and must be worn upon entering the lab and not
removed until clean-up is completed and you are leaving the lab (MN Statutes, Section
126.20 [Ex. 1967, C14, S1-6]). Goggles must be worn covering the eyes during all
activities using fire or glassware; mixing, handling or heating chemicals; chipping rock; or
whenever danger exists to the eyes. I will wear my safety goggles unless permission to
remove them is granted by the teacher. Be aware that students who wear contact
lenses may be at a greater risk should chemical enter their eyes because the contact will
aid in spreading the chemical across the surface of the eye and can trap gases. If you
wear contacts and chemical splashes in your eye, you must remove those contacts in
order to thoroughly rinse your eye.
I will wear other necessary apparel required for specific work, i.e. apron, gloves, closetoed shoes.
If an incident should occur that results in injury to others or myself in the classroom or
damage to equipment, I will immediately report it to my teacher, no matter how minor
the injury or damage may appear.
Chemical spills on skin or clothes should be flushed with water immediately and
continue flushing for several minutes. Should you spill acid or base on your clothing, the
contaminated article of clothing must be removed immediately so that the area of skin
under the clothing can be flushed.
Spills to the eyes must be immediately flushed using the eyewash station most like for
15 to 20 minutes.
For large chemicals spills, I will use vermiculite (kitty litter) to contain and absorb the
spill and report the spill to the teacher to determine what further treatment must occur.
If the large spill was an acid spill, I will sprinkle baking soda on the spill before using
vermiculite.
I will not eat, drink, or chew gum in the science classroom. I will always wash my hands
carefully after working in the laboratory even if chemicals were not used. Chemical
residue on the surface of the lab tables, from previous labs, can be transferred to skin
through contact with the lab table.
I will use proper techniques and be careful with sharp instruments.
It is important to know the exits to be used in case of emergencies. Students must not
sit in aisles, which would prevent emergency exit from the classroom. Likewise, projects,
materials, or equipment must not be stored so as to slow room evacuation. I am familiar
with exits and the appropriate action to take when the emergency signal is heard.
I will use the fume hood when working with volatile chemicals that produce flammable
or poisonous vapors. I will also use the hood when conducting experiments that may
produce a lot of smoke. I will make sure the fume hood is turned on and the sides are
down (so I can’t lean into the hood) every time I use the fume hood.
I will never remove chemicals or equipment from the classroom without the permission
of my teacher.
Please read through, sign, and bring back to Mr. Hoelz.
We have both read and acknowledge these classroom policies.
