3. Mixtures What do we already know? BrainPOP Teaser BrainPOP Teaser 1)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. Page 1

4. Mixtures : Vocabulary Part I 1)Mixture: a physical combination of two or more substances that do not form new substances (Salt water). 2)Suspension: is a mixture whose particles settle and separate within a few hours. 3)Solution: is a mixture whose particles are the size of atoms or molecules (not visible to the human eye). 4)Solvent: does the dissolving in a solution (water in salt water). 5)Solute: gets dissolved in a solution (salt in salt water).

8. 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. Page 6 Types of Matter: Lesson 2

9. 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.
