### 5th Grade-Ch. 11 Lesson 4 What are mixtures and solutions

1. 1. Ch. 11 Lesson 4 What are mixtures and solutions?
2. 2. Activity- Separating a Mixture <ul><li>Problem: What is the easiest way to separate a mixture? </li></ul><ul><li>Information: </li></ul><ul><li>mixtures can be separated by their different densities- </li></ul><ul><li>mixtures do not form compounds </li></ul><ul><li>Hypothesis: </li></ul>
3. 3. mixture all the beads solution colored water saturated solution salt water solute salt solvent water
4. 4. mixture <ul><li>different materials are together but do not bond to form compounds </li></ul>
5. 5. mixture <ul><li>materials can be separated b/c have different properties </li></ul>
6. 6. alloy <ul><li>metal that is mixture of elements </li></ul><ul><li>ex. brass, bronze </li></ul>
7. 7. solution <ul><li>special mixture-substances are spread out evenly & do not settle </li></ul>
8. 8. parts of a solution <ul><li>solute = smaller amount </li></ul><ul><li>solvent = larger amount </li></ul>
9. 10. In a salt water solution  solute= salt solvent= water
10. 11. saturated solution <ul><li>contains all the solute that can be dissolved w/out changing temp. </li></ul>
11. 12. concentrated solution <ul><li>has so much solute-almost saturated </li></ul>
12. 13. dilute solution <ul><li>far from being saturated </li></ul><ul><li>small amt. of solute </li></ul>
13. 14. Classify each item as either an element (E), a compound (C), or a mixture (M). Use your textbook & the periodic table to help you identify elements. <ul><li>water </li></ul><ul><li>hydrogen </li></ul><ul><li>soup </li></ul><ul><li>soil </li></ul><ul><li>sugar </li></ul><ul><li>sulfur </li></ul><ul><li>iron sulfide </li></ul><ul><li>iron </li></ul><ul><li>brass </li></ul><ul><li>sausage </li></ul><ul><li>oxygen </li></ul><ul><li>human body </li></ul><ul><li>chop suey </li></ul><ul><li>air </li></ul><ul><li>mercury </li></ul><ul><li>nitrogen </li></ul><ul><li>salt </li></ul><ul><li>bread </li></ul><ul><li>gold </li></ul><ul><li>aspirin </li></ul>
