Physical Science is the study of the interactions between matter and energy, as well
as studying the composition, structure, and properties of matter. It is the study of
the physical world using experiments, theories, and laws in ways that most people
are not used. To ensure you are better prepared for studying the physical world in
the same way, please complete this packet over the summer. This packet is due
within the first week of school. This packet will be worth regular credit points
and extra credit points, based on completion. Do note that the Safety Contract
(last page) must be completed and signed by all students enrolled in a science
course. Signing it now will save time, effort, and paper.
For more information, help, science links, on-line tutorials, or to

you might want answered or discussed in class is available at the

RULES OF PHYSICS
Learn ‘em Love ‘em Live ‘em
1.
Physics exists to teach us critical thinking – nothing else is important.
1b. If you’re not thinking critically, you’re just not thinking.
2.
Visualization is more important than units. Draw the picture, stupid.
3.
Units, units, units.
4.
Release the ego. Nothing ruins physics classes faster than physics classes.
5.
Don’t get too excited that your answer is correct. The next problem is just around
the corner, and the chances are that it will be a killer.
6.
Physics is not Mathematics – don’t treat it that way. Insanity lies down that road.
7.
All physics problems are the same problem. The difficulty is realizing what that
problem happens to be.
8.
There is a fine-line between hardcore and stupidity – try not to cross that line.
9.
The universe is stranger, and simpler, than you can ever imagine. Get used to it.
9b. The only way to truly understand the universe is to be born as an 11th
dimensional being. In all likelihood, you weren’t that lucky.
10. If it’s stupid, but it works, then it is not stupid.
11. If you understand the following quotes…
“Mathematicians know everything about nothing.
Engineers know nothing about everything.
Physicists know something about something.”
– Albert Einstein
“Everyone else sux.”
– Richard Feynman
…then you don’t need the previous 10 rules. Honest.

SAFETY RULES
These Safety Rules are minimum requirements for all science labs. In certain laboratory situations, more specific rules
may need to be applied. Working in a science laboratory is normally very safe. To ensure your personal safety and the
safety of others, you need to reduce the risks associated with laboratory work. Risk in the science lab can come from
either physical or chemical hazards. By examining these hazards, you will understand why the following rules have been
developed for working in scientific laboratories.
Chemical hazards result from exposure to hazardous chemicals from absorption through skin or eye contact,
inhalation, ingestion, or injection. Physical hazards include falls, eye injury, electrical shock and fire.

Protect your eyes. They are the most important part of your body. If you get a chemical in your eye, flush with
water immediately and tell the teacher. Appropriate eye protection must be worn at all times in the laboratory.
Chemical splash goggles provide maximum protection from splashes. Contact lenses should not normally be
worn unless approved by the teacher. Unventilated goggles are essential if contact lenses are worn.
Wear appropriate protective clothing. Chemicals can burn or irritate the skin. Some chemicals are readily
absorbed through the skin and enter the body. Your clothing should cover your legs to the knees. Shorts are not
appropriate for the laboratory. When applicable, laboratory coats or aprons can protect good clothing. Loose
clothing should not be worn because it may dip into chemicals or fall into a flame and catch fire.
Wear shoes that cover your feet. Sandals and open-toed shoes do not protect your feet from broken glass that
is frequently found in science laboratories. Also, leather shoes protect your feet from chemical spills; canvas
shoes do not.
Do not apply cosmetics, comb hair, eat, or drink in the laboratory. These activities are ways by which you
can accidentally ingest harmful chemicals.
Do not taste any chemical.
Do not smell chemicals directly. Smell a chemical; only if your teacher specifically tells you to do so, then use
your hand to fan the vapor to your nose.
Do not pipette solutions by mouth. Use a rubber suction bulb or other device to fill a pipette so that you do not
draw chemicals into the mouth.
Wash your hands with soap and water before leaving the laboratory. This rule applies even if you have been
wearing gloves.
Know the hazards of the materials being used. Read labels carefully to make sure you are using the right
chemical. Know how to interpret data from a Material Safety Data Sheet, MSDS. Remember that hot and cold
glassware look the same, so allow ample time for cooling. If you are not sure if the glassware is extremely cold or
hot, use precaution when handling that glassware.
Tie back loose hair. Dangling hair can fall into a Bunsen burner and catch on fire or can fall into a chemical
solution.
Know the safety equipment. Know the location of eyewash fountains, safety showers, fire blankets, fire
extinguishers, and emergency exits. Know how to respond in case of an emergency. Know how to use the safety
equipment.
Carry out only the experiments assigned by your teacher. Never perform unauthorized experiments.
Never remove chemicals from the laboratory.
Never work in the laboratory unless authorized to do so by your teacher. Never work alone in the laboratory.
In case of a problem, you may need another person to prevent injury or even save a life.
Never engage in horseplay, games, or pranks in the laboratory. Remember that the laboratory is a place for
serious work. Careless behavior can endanger yourself and others and will not be tolerated.
Demonstrate safe behavior. Obey all safety instructions given by your instructor or found in your experimental
procedure. Clean up spills immediately if you know how. If you are uncertain how to clean up a spill or if a large
spill occurs, notify your instructor immediately. Before leaving the laboratory, return equipment and chemicals to
their proper places. Clean up your work area.
Dispose of all waste materials according to your teacher’s instructions.
Report any accidents or unsafe conditions to your teacher immediately.
The procedures for heating chemicals are: (1) angle the test tube, (2) keep the test tube moving, and (3) point
the opening of the test tube away from others and yourself.

SAFETY CONTRACT
Students will be removed from the laboratory by the teacher if:




their personal appearance or dress is such that they can cause injury or distraction to
themselves or others;
they are behaving in such a manner that they can cause injury to themselves or others;
they are not following the prescribed safety rules for the laboratory or the particular activity
being conducted;
they have not completed the pre-lab activities that are needed for them to work safely in the
laboratory.
I,
, a student at
School, have read and agree to follow
all safety rules and regulations given by my teacher. I realize that following these rules is necessary
to ensure the safe operation of the school laboratory and to provide a safe environment not only for
myself, but for my fellow students and my teachers as well. I will, therefore, cooperate fully with
teachers and students to ensure that all of us work safely. I will act responsibly to look for possible
safety hazards and will immediately point out these hazards to the instructor. I realize that, as a
student, much of the responsibility for safety is in my hands. I understand that violation of these rules
may result in the loss of laboratory privileges and possible disciplinary measures.
Contact Lens Wearers
Wearing contact lenses in the laboratory is the subject of controversy because of the extra risk they
create in case chemicals enter the eye. Some experts believe that contact lenses should never be
worn in the laboratory. Other experts believe that contact lenses can be worn with proper eye
protection.
I will wear contact lenses in the laboratory. Yes____ No____. If yes, I realize the hazards associated
with the use of contact lenses and will strictly adhere to the eye protection requirement.
