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
