1. Unit 3 Exam Review Made by Ms. Manhart’s classes

2. Solutions Solvent & Solute Gabriela and Brianna

3. Definitions Solutions: They are the best mixed mixtures. They have the smallest particles. They stay suspended and they are clear (see through). Solute: Is the part that gets dissolved and could be more than one substance in a mixture. Solvent: Is the greatest amount and does the dissolving.

4. Solution: Salt Water Solvent: WaterSolute: Salt

5. Kool Aid Solvent: WaterSolute: Powder

6. Lemonade Solvent: Water Solute: Sugar and Lemon Juice

7. Hot Chocolate Solvent: MilkSolute: Chocolate Powder

8. Crystal Light Solvent: WaterSolute: Powder

9. Colloids vs. Suspensions By Brianna M. and Gwen D.

10. Colloids A mixture with medium particles that you can see with a microscope. The particles are suspended within the substance. The substance is translucent and it scatters light. Example: Fog or Smoke

11. Suspension A mixture with large particles that are visible to the bare eye. The particles settle to the bottom and are opaque. Example: Sand in water, snow globes or salad dressing

12. Fog- Colloid

13. Milk- Colloid

14. Smoke- Colloid

15. Sand in water- Suspension

16. Snow Globes- Suspension

17. Salad Dressing- Suspension

18. Colloids vs. Suspensions

19. Colloid A mixture containing small, undissolved particles that do not settle out.

20. suspension A mixture in which particles can be seen, and easily separated by settling or filtration.

21. Example 1 Salt water is an example of a suspension. The salt particles will eventually settle to the bottom.

22. Example 2 Salad dressing is an example of a suspension. This is because a the particles with a higher density fal to the bottom

23. Example 3 Milk This is because the substances in milk will not settle out, and cannot be filtered out.

24. SOLUTES AND SOLVENTS (SOLUTIONS) By:Josey, Alex and Cecilla

25. THE SOLUTION SONG http://www.youtube.com/watch?v=3G472AA3SEs

26. SOLUTES Solutes:The substance that gets disolved. They are things that are soluble!

27. EXAMPLES OF SOLUTES Examples: Lemonade and Water The lemonade powder is what is being dissolved. The water is doing the dissolving because when the powder is all gone the mixture becomes LEMONADE!

28. EXAMPLES OF SOLUTES Example: Sugar and Water Sugar is an example of a solute because sugar is what gets dissolved in water.

29. EXAMPLES OF SOLUTES Example: Milk and Hot chocolate When you mix hot chocolate powder with warm milk you create HOT CHOCOLATE!

30. SOLVENTS Solvent:Largest part of a solution: does the disolving.

31. EXAMPLES OF SOLVENT THIS DOES THE DESSOLVING

32. Homogeneous vs. Heterogeneous

33. Heterogeneous: You can see the different parts of the substance. Can only be a mixture. Homogeneous: You can’t see any different parts of the substance. Can be either a mixture or a compound.

34. Homogeneous Examples

35. Heterogeneous Examples

36. Colloids, Suspension, or Solution By Aiden and Aliea

37. Colloids Medium sized particles Cant see individual particles Particles stay suspended Translucent-allows light to pass through but disrupts images.

38. Fog

39. Milk

40. Shaving Cream

41. Smoke

42. jello

43. Suspension Large sized particles Can see particles easily Particles settle to the bottom of mixture Cannot see through them

44. Muddy Water

45. Snow Globe

46. Salad Dressing

47. Solar System

48. Dust

49. Solution Small sized particles Cannot see individual particles Particles stay suspended Homogeneous

50. Sugar Water

51. Salt Water

52. Peach Juice

53. Test Review Woo who!!!!!!!!?!!! Chemical and Physical Changes

54. Physical changes and Chemical changes. A physical change is any change that changes the appearance but not the chemical composition. A chemical change is a change in matter that makes one or more new substances.

55. Physical Change Add food coloring to water.

56. Physical Change Cutting a cucumber.

57. Physical Change Melting butter.

58. Chemical Change Burning a log.
