  1. Today’s Agenda… • Bellringer: Create a T-chart to compare elements and compounds • Frayer Model • Notes on Mixtures

  2. Mixtures Study Pack #11

  3. Today’s Target… • I can describe mixtures.

  4. What is a mixture? • Two or more substances combined • When the substances come together a physical change takes place • So the substances can be separated

  5. What is a mixture? • Since a physical change takes place when the substances come together it DOES NOT create a new substance • The original substances in a mixture keep their properties • Example: In a salad each substance in the salad keeps its own properties

  6. What is a mixture? • Mixtures do not have substances in fixed amounts • Example: When you make a salad you don’t have to have a certain number of cucumbers or tomatoes

  7. What is a mixture? • Mixtures are not represented by formulas

  8. Examples of Mixtures • Salt water • Salad • Toys in a toy chest • Soap

  9. Types of Mixtures • Heterogeneous mixtures • Homogeneous mixtures

  10. Homogeneous Mixtures • Homogeneous means “the same throughout” • You can’t see the different parts in this type of mixture • Sometimes also called a solution • Sometimes you might not even know they are mixtures because you can’t see all the parts that they are made up of • Examples: salt water, lemonade, air

  11. Heterogeneous Mixtures • Has larger parts that are different from each other • You can see the different parts in this mixture • Examples: pizza, sand and water

  12. Homework • Create a frayer model for mixture
