  1. Physical Science Unit Overview: Chapter 7 – Types of Matter Lesson 1 – Properties of Matter Lesson 2 – Elements Lesson 3 – Classifying Elements Lesson 4 – Mixtures Lesson 5 - Compounds Chapter 8 – Changes in Matter Lesson 1 – Chemical Reactions Lesson 2 – Metals and Alloys Lesson 3 – Salts

  2. Mixtures Lesson Overview: 1) What do we already know? 2) Vocabulary 3) Drawings 4) Main Ideas 5) Review Types of Matter: Lesson 2

  3. Page 1 MixturesWhat do we already know?BrainPOP Teaser What are the 3 categories of elements? a) Metal, metalloid, and Nonmetal 2) What are molecule? a) It is a particle that contains more than one atom joined together.

  4. Page 2 Mixtures : Vocabulary Part I Mixture: a physical combination of two or more substances that do not form new substances (Salt water). Suspension: is a mixture whose particles settle and separate within a few hours. Solution: is a mixture whose particles are the size of atoms or molecules (not visible to the human eye). Solvent: does the dissolving in a solution (water in salt water). Solute: gets dissolved in a solution (salt in salt water). Types of Matter: Lesson 2

  5. Page 3 Mixtures: Vocabulary Part II(pg. 354-355) 6) Solubility: it is the greatest amount of solute that a given amount of solvent can dissolve. 7) Filtration: separates substances that have particles of different sizes. 8) Homogenous: solutions that have the same makeup throughout (Salt water). 9) Heterogeneous: separate particles are big enough to see (Salad Dressing). Types of Matter: Lesson 2

  6. Mixtures Drawings (pg. 378-379) Page 4 Types of Matter: Lesson 2

  8. Page 6 Mixtures : Main Ideas 1) What is a Mixture? (pg. 378-379) A physical combination of two or more substances, such as salad dressing, trail mix, and chocolate milk. 2) How are mixtures classified? (pg. 378) They are either heterogeneous or homogenous. - Heterogeneous mixture is when separate particles are big enough to see. For example, salad dressing, trail mix, and granola bars. - Homogenous mixtures look the same throughout and have particles that are to small to see. For example, salt water, window cleaner, and cream cheese. Types of Matter: Lesson 2

  9. Page 7 Mixtures : Main Ideas 3)What are the parts of a solution? (pg. 380) The solvent and the solute. The solvent is the part that does the dissolving (liquid) and the solute is the part that dissolves (solid). * In a liquid-liquid, solid-solid, and gas-gas solution the part that is present in the greatest amount is the solvent and the part in the smaller amount is the solute.
