HOW DO YOU DESCRIBE MATTER? ANSWER: WE CLASSIFY IT!! GOAL: DESCRIBES AND CITES EXAMPLES OF PHYSICAL AND CHEMICAL PROPERTIES OF MATTER.

The Atom - Atoms react or not depending on its electron structure. - All atoms desire to have a full outer electron shell. - Metals will lose e - and nonmetals.

Element – a substance that cannot be broken down into simpler substance by chemical means. Atom – the smallest unit of an element that still has all of.

 Matter is composed of extremely small particles, too small to be seen with a classroom microscope, called atoms.  Atoms: smallest part of an element.

HAPPY THURSDAY! Copy down tonight’s homework. Please get your folders.

TODAY, WE WILL: Do a warm-up Talk about what will be on tomorrow’s quiz Take some “quick notes” on classifying matter

WARM-UP As you watch this short video, about the aborted Red Bull Stratos launch, be aware of examples of matter and non- matter.

WARM-UP As you watch this short video, about the aborted Red Bull Stratos launch, be aware of examples of matter and non- matter. OK – Now, write down three INTERESTING examples of matter that you saw and three examples of things that are not matter.

We’ll be talking a lot about PARTICLES in this unit. So, what is a particle? A particle is the smallest piece of a substance. 10/11 Obj: Describe pure substances and mixtures

A particle can be:  a single atom  a molecule, which is two or more atoms that are connected by chemical bonds.

one atom of oxygen (O) one particle of water (H 2 O) one atom of hydrogen (H) A really small YOU swimming in a cup of water another atom of hydrogen

All materials on earth are either made of a pure substance or a mixture of substances. Matter - Has mass, takes up space and is made of atoms Matter - Has mass, takes up space and is made of atoms Are all of the particles the same? YESNO Pure Substance Mixture

PURE SUBSTANCE Matter that is made of one kind of “thing” All of the particles are the same.

Mixtures Definition: matter made of more than one kind of substance that are combined in the same container but not held together with chemical bonds. There are different PARTICLES in the container. Tank containing oxygen and hydrogen gases particle of oxygen particle of hydrogen

Mixtures There are two types of Mixtures: 1.Heterogeneous Mixtures 2.Homogeneous Mixtures

Heterogeneous Mixtures Definition: A mixture in which different materials can be distinguished easily.- not well-blended. Examples: GranolaSalad Dirt

Homogeneous Mixtures Definition: a mixture in which the different substances are indistinguishable - you can’t see the different substances because it is well- blended. It looks the same everywhere. Can also be called a SOLUTION. Examples: Vinegar a gold ring

Matter - Has mass and takes up space Matter - Has mass and takes up space Are all of the particles the same? YESNO Pure Substance Mixture Does it look the same throughout? NOYES HOMOGENEOUS HETEROGENEOUS EXAMPLES

BEFORE YOU LEAVE… What kind of matter is: Lucky Charms cereal your table top a shirt distilled (pure) water the gas in an oxygen tank Godzilla a piece of computer paper a piece of lined paper
