### Transcript of "Mixtures And Solutions Lesson 1"

1. 1. Mixtures and Solutions Lesson 1 Classifying Mixtures and Solutions
2. 2. What is a Mixture? <ul><li>A mixture is a combination of two or more different kinds of matter (solid, liquid, gas) or substances, each of which keeps its own physical properties. </li></ul>
3. 3. What is a Mixture? <ul><li>A substance is anything that contains only one kind of material. Examples would be sugar, water, iron filings </li></ul><ul><li>When you mix sugar with iron filings, you can easily see the two solids in the mixture. </li></ul>
4. 4. Identifying Mixtures <ul><li>Homogenous Mixtures </li></ul><ul><ul><li>A mixture in which the different substances are mixed evenly , and are too small to be seen. </li></ul></ul><ul><ul><li>No matter how long you let a powdered drink mix and water stand, like Kool-Aid, the evenly mixed particles that make up this homogenous mixture will not separate. </li></ul></ul>
5. 5. Identifying Mixtures <ul><li>Heterogenous Mixtures </li></ul><ul><ul><li>A mixture in which the different substances are mixed unevenly . </li></ul></ul><ul><ul><li>Many times you can see the different substances in the mixture. Examples would be: bread, chocolate milk, smoke and air, paper, sugar mixed with iron filings. </li></ul></ul>
6. 6. What is a Solution? <ul><li>Sugar and Water </li></ul><ul><ul><li>When you mix sugar and water, it’s not easy to tell what is in the mixture. </li></ul></ul><ul><ul><li>The sugar seems to disappear. </li></ul></ul><ul><ul><li>But if you taste it, you’ll find that the water is sweet. It is distributed evenly throughout the mixture. </li></ul></ul><ul><ul><li>When one substance dissolves in another, the two form a solution . </li></ul></ul><ul><ul><li>In other words, any mixture made up of tiny particles that are evenly mixed and do not settle out is called a solution. </li></ul></ul>
7. 7. What is a Solution? <ul><li>A solution is a specific type of mixture. </li></ul><ul><ul><li>Are all solutions mixtures? Yes </li></ul></ul><ul><ul><li>Are all mixtures solutions? No </li></ul></ul><ul><li>Solubility is the ability to be dissolved. </li></ul><ul><li>Sugar is soluble in water, but ground black pepper is not. </li></ul>
