1. Classification of Matter HETEROGENEOUS vs. HOMOGENEOUS

2. Classification of Matter Using the glossary in your book define the following words in your notes. 1)Pure Substance 2)Element 3)Compound 4)Solution 5)Mixture 6)Homogeneous 7)Heterogeneous

3. Classification of Matter MATTER Heterogeneous Matter Homogeneous Matter 1)Solid Mixture Fluid mixtures 2) Colloids3) Suspensions 4) SolutionsPure Substances 5) Elements 6) Compoundsemulsions Gels Aerosols

4. Classification of Matter List an example of each below: Element  Zinc Compound  Carbon Dioxide Solution  Stained glass Solid Mixture  Granite Suspensions  Pulpy Orange Juice Colloids  Milk, Jell-O, Hair Spray Try and come up with two other examples of each of the classifications of matter. In a minute I will unveil possible answers. Get all your answers before the music stops

5. Matter Matter is anything That takes up space and has some mass. It comes in many forms like solid liquid or a gas. Water, gold and salt… well they are substances for sure… there’s no Physical way to break them down, So they are classified as Pure

6. Matter  Chorus Matter… Does it matter? HEY… matter means a lot! Matter is the only stuff we got.

7. Matter Substances are either, compounds or elements…you can break down compounds chemically., But with elements you can’t. Put substances together, and a mixture is what you get Mixtures are either hetero, or homogeneous.

8. Matter  Chorus Matter… Does it matter? HEY… matter means a lot! Matter is the only stuff we got.

9. Matter Mixtures are homogeneous, when they’re uniform throughout. Solutions like salt in water Are examples without a doubt. Mixtures are heterogeneous That lack uniformity, Like a mixture of dirt and water, That’s as clear as mud to me.

10. Matter  Chorus Matter… Does it matter? HEY… matter means a lot! Matter is the only stuff we got.

11. Matter  Chorus Matter… Does it matter? HEY… matter means a lot! Matter is the only stuff we got.

12. MATTER IS EVERYWHERE It is anything that takes up space and has mass.

13. Classification of Matter List an example of each below: Element  Zinc Compound  Carbon Dioxide Solution  Stained glass Solid Mixture  Granite Suspensions  Pulpy Orange Juice Colloids  Milk, Jell-O, Hair Spray For homework come up with two other examples of each of the classifications of matter.

14. Classification of Matter What is a colloid? What is a suspension? How are they different from a solution? Go to page 224-231 and read about colloids suspensions and solutions. Define in your notes the italicized words.

15. Classification of Matter SolutionsColloidsSuspensions HomogeneousHeterogeneous Particle size: 0.01–1 nm Particle size: 1–1000 nm Particle size: over 1000 nm Do not separate on standing Particles settle out, Shake before use. Cannot be separated by filtration or membrane. Cannot be separated by filtration. Only by membrane Can be separated by filtration or membrane. Do not scatter light Scatter light (Tyndall effect) May scatter light, but are not transparent
