WHAT IS URANIUM?

Matter

How is one kind of matter different from another kind?

What makes up matter?

How does matter behave?

WHAT IS MATTER?

• Anything that has mass and takes up space.

WHAT MAKES UP MATTER? • Atom=smallest unit of matter

• (IT’S, REALLLLLLLY SMALL)!•magnifying the universe

Structure of Matter

WHAT MAKES UP AN ATOM? •Protons=positive charge•Neutrons=neutral in a car=no charge•Electrons=electricity= “-”•Nucleus contains protons and neutrons •Quarks could make up protons and neutrons

•Electrons orbit around nucleus (kinda like a fan)

SIZE OF ATOMIC PARTICLES

• Atomic Mass of particles:• 1 neutron about = 1 proton• 1,836 electrons = 1 proton

• Lots of empty space in an atom• If bowling

ball=proton/neutron• Golf ball= electron• Football field= space in-

between

addoms family

HOW IS ONE KIND OF MATTER DIFFERENT FROM ANOTHER

KIND?

ELEMENTS VS. MOLECULES 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•Have a different number of protons and electron

• FORMULA = Only one capital letter

MOLECULES •Molecules are two or more atoms joined together of the same element…• Examples: O2, Cl2, etc.

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

WARM-UP 10/30/13• Teach the Teacher: What would be the most fun activity to do at a nursing home?

• Review: What charge does a neutron have?

WARM-UP 10/31/13• Teach the Teacher: What is the worst thing anyone has ever gotten tricker-treating?

• Review: What is the part of an explanation where you discuss how the evidence supports the claim?

WARM-UP 11/4/13• Teach the Teacher: What was the best Halloween costume of 2013?

• Review: What is the part of an experiment that you keep the same?

WHAT DOES MATTER DO?

PHYSICAL CHANGES/PROPERTIES • Physical properties: describe what the

element/compound is like just hanging out • 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 PROPERTIES/CHANGE• Chemical properties: describe what will happen

to an element/compound if something is done or added to it. • 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 REACTION • Chemical change happens

during a chemical reaction

• Never a change in the number of elements • Conservation of Matter:

matter can never be destroyed or created• Energy is always taken in or

given off

WHAT ARE THE 4 STATES OF MATTER?

•Matter comes in 4 different states

SolidLiquid Gas Plasma

Atoms atoms family

PLASMA• Plasmas consist of freely

moving charged particles• electrons & ions

• Plasma is formed at high temperatures when electrons are stripped from neutral atoms• Examples: Sun, plasma

Tv’s, Northern lights

KINETIC(MOVING) MOLECULAR THEORY

Molecules/atoms are always randomly moving!

• Solids= very little movement• Liquids= more movement• Gases= lots of movement

What happens in gasses • Particles collide (but don’t lose

energy, no friction) into each other or the walls of the container

• Particles are not attracted to each other

• Speed of the particles and number of collisions depends on the temperature of the gas

PROPERTIES OF FLUIDS Bernoulli’s Principle • Increased speed of a fluid or

gas=decreased pressure • Look at picture• A=fast moving air• B= slow moving air• A= less pressure• B= more pressure, more

pressure pushes on bottom of wing= flying
