Warm-up 10/2/12
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?
AtomsMatterProperties of fluidsProperties of GasesMixturesChemical change Physical Change
Physical Science 1 The Stuff that Matters
What is Physical Science?
◦Study of matter and energyPhysics, Chemistry, Astronomy, & Geology
What is matter?
Anything that has mass and takes up space.
What makes up matter?
Atom=smallest unit of matter
Structure of Matter
What makes up an atom?
ProtonsNeutrons ElectronsProtons=positive chargeNeutrons=neutral in a car=no
chargeElectrons=electricity= “-”Nucleus contains protons and
neutrons ◦Quarks could make up protons and neutrons
Warm-up 10/3/12
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.
Don’t Say It! (Educational Taboo)
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)
Size of atomic particles
addoms family
What are the 4 states of matter?
Matter comes in 4 different states
SolidLiquid Gas Plasma Atoms atoms family
Warm-up 10/4/12
Teach the Teacher: What type of car best fits your personality?
Review: What are the different states of matter (4)?
Properties of Fluids
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
Warm-up 10/5
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
Flash Card
On the Front:
Parts of an atom
On the back:
Protons (+)Neutrons (0) (N&P=size)Electrons (-)
(much smaller)
On the front write:
Bernoulli’s Principle
On the back write:
Fast air=low pressure (light)
Slow air=high (heavy) pressure ( )
(airplane wing)
Properties of Gases
Boyle’s Law
A smaller container of gas will have a higher pressure (if at the same temp) then a larger container of gas
PlasmaPlasmas consist of
freely moving charged particles◦electrons & ions
Plasma is formed at high temperatures when electrons are stripped from neutral atoms
Classification of Matter
Matter
Substances
Compound Element
Mixture
Heterogeneous Homogeneous
Elements vs. Compounds
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
Compound
Compound◦Two or more elements bonded together.
◦Bond in ratiosWater = H2O it will always have 2 hydrogen atoms for every 1 oxygen atom.
Formula= more then one capitol letters
FORMULA = more than 1 capital letter
MixturesMixture—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 MixturesMixture
◦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 substanceA change in size, shape or state of
matter is a physical change “3S”
Chemical ChangeThe 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 Reaction
Chemical change happens during a chemical reaction
Never a change in the number of elements
Energy is always taken in or given off

Warm-up 2/3/11
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)
