 Teach
the Teacher: What is the most
adventurous thing you have ever
done?
 Review:
Why do we have
independent and dependant
variables and control groups in the
scientific method?

Physical Science 1
The Stuff that Matters
◦ Study of matter and energy
Physics, Chemistry,
Astronomy, & Geology
What is Physical Science?
 Anything
space.
that has mass and takes up
What is matter?
 Atom=smallest
unit of matter
Structure of Matter
What makes up matter?
 Protons
 Neutrons
 Electrons
 Protons=positive charge
 Neutrons=neutral in a
car=no charge
 Electrons=electricity= “-”
 Nucleus contains protons
and neutrons
◦ Quarks could make up
protons and neutrons
What makes up an atom?
 Teach
the Teacher: What is one thing
that would make school 10x cooler?
 Review:
List as many parts of an
atom as you can remember.

Find a partner, Pound it!
Introduce yourself
Whoever is taller goes first: looks at other person’s
back gives a clue as to what the word is
Second person looks at the other person’s back and
gives clues as to what the word is
Keep giving clues until the music starts, DON’T Guess
until the end!
Don’t say the word on the card! (or what it sounds like
or starts with)
When music starts find a new partner (can’t use the
same partner more then once)
addoms family
Size of atomic particles
 Matter
comes in 4 different states
Solid
Liquid
Gas
Plasma
Atoms atoms family
What are the 4 states of
matter?
 Teach
the Teacher: What type of car
best fits your personality?
 Review:
What are the different
states of matter (4)?
Warm-up 10/4/12
 Buoyancy:
ability of a fluid
to exert an
upward force on
an object
Properties of Fluids
Bernoulli’s Principle

Increased speed of a
fluid or
gas=decreased
pressure
Properties of Fluids
 Teach
the Teacher: What was your
favorite thing to do as a little kid?
 Review:
Draw a picture of the shape
of an airplane wing, or the upward
force of water on the basketball


A smaller container of
gas will have a higher
pressure (if at the
same temp) then a
larger container of
gas
Properties of Gases
Plasma

Plasmas consist of
freely moving
charged particles
◦ electrons & ions

Plasma is formed at
high temperatures
when electrons are
stripped from neutral
atoms
Matter
Substances
Compound
Element
Mixture
Heterogeneous
Homogeneous
Classification of Matter


Element
◦ A substance that cannot be broken down by chemical
means
◦ 90 naturally occurring elements found on Earth
◦ 20+ man made elements (nuclear bombardment)
◦ Elements are listed on the Periodic Table
FORMULA = Only one capital letter
Elements vs. Compounds

Compound
◦ Two or more elements
bonded together.
◦ Bond in ratios
 Water = H2O it will
always have 2
hydrogen atoms for
every 1 oxygen
atom.
 Formula= more then
one capitol letters
Compound
Mixtures
 Mixture—a
material made of 2 or more
substances that can be separated
physically.
 There are 2 types of mixtures:
heterogeneous and homogeneous.
Heterogeneous Mixture—different
materials can be distinguished easily.
◦ Ex. Pizza, salad, chocolate chip
cookies (mmm), pepper jack cheese
 Homogeneous Mixture—substances
are blended evenly throughout.
◦ Ex. Pop, vinegar, cheddar cheese
◦ A homogeneous mixture is also called
a solution.

Types of Mixtures

Mixture
◦ Is made up of two or more substances that can be
easily separated by physical means.


Mixtures do not have to have the same
proportions
Two types of mixtures
◦ Heterogeneous
 A mixture where the substances can be easily
distinguished
 Most substances you come in contact with are
heterogeneous
◦ Homogeneous
 2 or more substances blended evenly throughout
Physical Changes


Physical changes DO NOT alter the
identity of the original substance
A change in size, shape or state of
matter is a physical change “3S”
Chemical Change

The change of one substance to another is a
chemical change

6 Clues that a chemical change has occurred
◦
◦
◦
◦
◦
◦
Color change
Bubbles (not boiling)
New odor
Heat or Cooling
Light
Sound

Chemical change
happens during a
chemical reaction

Never a change
in the number of
elements

Energy is always
taken in or given
off

 Review
questions: List as many
physical changes as you can think of
(where something changes size,
shape, or state but is still the same
substance) (ex: tearing paper)

 Teach
the teacher questions: List all
the cartoons you have seen more
then once (ex: Sponge Bob)
