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

W ARM-UP

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

W ARM-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 (H2O)

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

Are all of the particles the same?

YES NO

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.

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: Granola Salad 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

Are all of the particles the same?

YES NO

Pure Substance Mixture

Does it look the same throughout?

NOYES

HOMOGENEOUS HETEROGENEOUS
