WHAT IS URANIUM?
Matter
How is one kind of matter different from another kind?
What makes up matter?
How does matter behave?
![Page 15: Warm-up 10/11/13](https://reader036.vdocuments.site/reader036/viewer/2022081507/56816291550346895dd2fe49/html5/thumbnails/15.jpg)
WHAT IS MATTER?
• Anything that has mass and takes up space.
![Page 16: Warm-up 10/11/13](https://reader036.vdocuments.site/reader036/viewer/2022081507/56816291550346895dd2fe49/html5/thumbnails/16.jpg)
WHAT MAKES UP MATTER? • Atom=smallest unit of matter
• (IT’S, REALLLLLLLY SMALL)!•magnifying the universe
Structure of Matter
![Page 17: Warm-up 10/11/13](https://reader036.vdocuments.site/reader036/viewer/2022081507/56816291550346895dd2fe49/html5/thumbnails/17.jpg)
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)
![Page 18: Warm-up 10/11/13](https://reader036.vdocuments.site/reader036/viewer/2022081507/56816291550346895dd2fe49/html5/thumbnails/18.jpg)
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?
![Page 20: Warm-up 10/11/13](https://reader036.vdocuments.site/reader036/viewer/2022081507/56816291550346895dd2fe49/html5/thumbnails/20.jpg)
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
![Page 21: Warm-up 10/11/13](https://reader036.vdocuments.site/reader036/viewer/2022081507/56816291550346895dd2fe49/html5/thumbnails/21.jpg)
MOLECULES •Molecules are two or more atoms joined together of the same element…• Examples: O2, Cl2, etc.
![Page 22: Warm-up 10/11/13](https://reader036.vdocuments.site/reader036/viewer/2022081507/56816291550346895dd2fe49/html5/thumbnails/22.jpg)
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
![Page 23: Warm-up 10/11/13](https://reader036.vdocuments.site/reader036/viewer/2022081507/56816291550346895dd2fe49/html5/thumbnails/23.jpg)

![Page 24: Warm-up 10/11/13](https://reader036.vdocuments.site/reader036/viewer/2022081507/56816291550346895dd2fe49/html5/thumbnails/24.jpg)
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?
![Page 25: Warm-up 10/11/13](https://reader036.vdocuments.site/reader036/viewer/2022081507/56816291550346895dd2fe49/html5/thumbnails/25.jpg)
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?
![Page 26: Warm-up 10/11/13](https://reader036.vdocuments.site/reader036/viewer/2022081507/56816291550346895dd2fe49/html5/thumbnails/26.jpg)
WHAT DOES MATTER DO?
![Page 27: Warm-up 10/11/13](https://reader036.vdocuments.site/reader036/viewer/2022081507/56816291550346895dd2fe49/html5/thumbnails/27.jpg)
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”
![Page 28: Warm-up 10/11/13](https://reader036.vdocuments.site/reader036/viewer/2022081507/56816291550346895dd2fe49/html5/thumbnails/28.jpg)
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
![Page 29: Warm-up 10/11/13](https://reader036.vdocuments.site/reader036/viewer/2022081507/56816291550346895dd2fe49/html5/thumbnails/29.jpg)
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
![Page 30: Warm-up 10/11/13](https://reader036.vdocuments.site/reader036/viewer/2022081507/56816291550346895dd2fe49/html5/thumbnails/30.jpg)
WHAT ARE THE 4 STATES OF MATTER?
•Matter comes in 4 different states
SolidLiquid Gas Plasma
Atoms atoms family
![Page 31: Warm-up 10/11/13](https://reader036.vdocuments.site/reader036/viewer/2022081507/56816291550346895dd2fe49/html5/thumbnails/31.jpg)
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
![Page 32: Warm-up 10/11/13](https://reader036.vdocuments.site/reader036/viewer/2022081507/56816291550346895dd2fe49/html5/thumbnails/32.jpg)
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
![Page 33: Warm-up 10/11/13](https://reader036.vdocuments.site/reader036/viewer/2022081507/56816291550346895dd2fe49/html5/thumbnails/33.jpg)
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
A
B
