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

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

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

5. 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.

6. 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

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

8. 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

9. 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

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

12. 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

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

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

15. 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

16. 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

17. 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
