Unit 1:“About Science”
Introduction to PHYSICS
Physics - The Basic Science Natural philosophy-the study of unanswered questions about nature; as the questions were answered, this became known as present-day Science.
I. LIFE SCIENCES:
Biology Zoology Botany
II. PHYSICAL SCIENCES:
Geology Astronomy Chemistry Physics
Physics studies motion, forces, energy, matter, heat, sound, light, atoms
Physics (foundation for…)Chemistry (foundation for…)Biology
Mathematics – “universal” language
When information is expressed mathematically, it is easier to prove or disprove correctness
Mathematics – The Language of Science
Example:1. A red car is driving slowly; a blue car is
driving quickly(slowly or quickly relative to what?)VS 2. A car is driving at 35 mph, and a blue car is
driving at 110 mph(mathematical terms – more clear)
Scientific Methods
Methods used in science in gaining, organizing and applying knowledge
Problem – what question do you want answered? Hypothesis – what do you THINK the answer might
be? (an educated guess)
The hypothesis must be TESTABLE (scientists must be able to experiment to test the hypothesis)
Steps of the Scientific Method
For example:
Atoms are the smallest particles of matter – TESTABLE
VSAlbert Einstein is the greatest physicist of
all time – NOT TESTABLE
FACT – a close agreement by competent observers of a series of observations of the same phenomenon
(EX: water freezes at 0 degrees Celsius)
Scientific Attitude
Scientific Attitude, cont.• THEORY – a synthesis of a large body
of information that encompasses well-tested and verified hypotheses about certain aspects of the natural world
Theories are based on facts. (EX: Theory of Relativity, Theory of
Evolution)
LAWS or PRINCIPLES – a general hypothesis or statement about the relationship of natural quantities that has been tested over and over again and has not been contradicted
(EX: Newton’s Laws of Motion)
Scientific Attitude
Prediction – what will happen if your hypothesis is correct?
Experiment – test your hypothesisResults – visually show what you learned
in your experiment (usually charts and graphs)
Conclusion – was your hypothesis correct? What did you learn from the experiment?
Scientific Method Steps, cont.
Science, Technology, and Society
SCIENCE deals with theoretical questions;
It is a “way of knowing”TECHNOLOGY deals with practical
problems; it is a “way of doing”What do you think - Is technology
good or bad?
All are pathways to search for order and meaning
SCIENCE investigates natural phenomenonART is the creation of objects or events that
stimulate the sensesRELIGION is the belief in nature’s purpose
The 3 do not exist alone. The blending of all 3 creates diversity among scholars.

“Courage is not the absence of fear, but rather the judgment that something else is more important than fear.”

Laboratory SafetySafety Objectives:
1.The student must understand the importance of safety in the laboratory as it relates to itself and those around them.
2.The student must be able to explain the meaning of common safety symbols used in specific scientific fields of study.
3.The student must demonstrate complete knowledge of laboratory safety rules.
4.The student must be able to demonstrate proper safety practices in the laboratory setting.

Explanation of Symbols
Goggles- Wear safety goggles to protect your eyes during labs that use chemicals, flames or heating, or the possibility of broken glass.
Apron- Wear a lab apron to protect skin and clothing.
Breakage- handle breakable materials with care. Do not handle broken glass.Heat-resistant gloves – Use hand protection when handling hot materials. Do not touch hot materials with bare hands.
Electrical Shock- Never use electrical equipment around water, or when equipment or hands are wet. Be sure cords are untangled and can’t trip anyone. Disconnect equipment when not in use.No Open Flames- Flammable materials may be present. Make sure no flames, sparks, or exposed heat sources are present.
Physical Safety- When an experiment involves physical activity, take precaution not to injure yourself or others. Alert your teacher of any reason that you should not participate in the activity.
Explanation of SymbolsProper Disposal- Not everything goes in the trash or sink. Follow teacher’s directions as to where to dispose of all materials.
Hand Washing- Wash hands thoroughly after all lab activities.
General Safety- Follow additional safety precautions given by your teacher.Toxic/poison- Do not let poisonous chemicals come in contact with your skin, clothing or eyes. Do not inhale vapors. Wash hands when you are done with the activityOpen Flames- You will be working with open flames. Tie back loose hair and clothing. Follow teacher’s instructions about lighting and extinguishing flames.
Fumes- Work in a well-ventilated area or the fume hood. Do not inhale directly. Use wafting if you are to test the odor of a vapor.
Heating - Use a clamp or tongs to handle hot glassware. Do not pick up hot glassware with your hands.
Corrosive- Do not let chemicals come in contact with your skin, clothing or eyes. Do not inhale vapors. Wash hands when you are done with the activity
