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?

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)
