1. Chemistry Mrs. Algier Do Now: Explain the difference between an intensive and an extensive property.

2. YWBAT Distinguish between a substance and a mixture. Differentiate between heterogeneous and homogeneous mixtures Explain how mixtures can be separated

3. Matter Classification Matter Mixture Substance

4. Mixtures Mixture – a physical blend of two or more components Examples?

5. Mixtures Mixture – a physical blend of two or more components Examples – Salad – Chocolate chip cookie – Coffee with milk and sugar – Gasoline – Air

6. Matter Classification Matter Mixture Substance Heterogeneous Homogeneous

7. Heterogeneous Mixtures Heterogeneous Mixture – a mixture in which the composition is not uniform throughout. Examples – Salad – Chocolate chip cookie – Chicken noodle soup

8. Homogeneous Mixtures Homogeneous Mixture – a mixture in which the composition is uniform throughout. Another name for a homogeneous mixture is a solution. Examples – Vinegar – Air

9. Phase Phase– any part of a sample with uniform composition and properties. Homogeneous Mixtures – 1 phase Heterogeneous Mixtures – 2 or more phases

10. Separating Mixtures Differences in physical properties can be used to separate mixtures Methods – Filtration – separates a solid from a liquid – Distillation – separates liquids based on boiling pt. – Magnetism

11. Filtration Filtration – the process that separates a solid from a liquid in a heterogeneous mixture – Filter paper is placed in a funnel. – The mixture is poured into the funnel. – Solid particles that cannot pass through the filter remain in the funnel. – The rest of the particles pass through.

12. Distillation Distillation – process which separates mixtures of liquids with different boiling points
