  6. Do Now: (3 min) On a SEPARATE sheet of paper, write your name, period and date. Answer the following questions (the copier broke - this is your Do Now sheet for the next two weeks) Explain the difference between a heterogeneous and a homogeneous mixture. Are the following examples elements, compounds, homogeneous or heterogeneous mixtures? 1 2 3

  7. Do Now Discussion Explain the difference between a heterogeneous and a homogeneous mixture. One can see all the separate parts of a heterogeneous mixture while a homogeneous mixture looks the same throughout. Are the following examples elements, compounds or mixtures? 1 2 3 Mixture! Element! Compound!

  8. Separating Mixtures 10/19/09 Cornell Notes

  9. Last Week: (don’t write this) Matter Pure Substance Mixture Homogenous Heterogeneous Element Compound

  10. Why would we separate a mixture? • Cleaning water • Oil processing • Making candy • Salt and Sugar Production

  11. Mixture A physical blend of pure substances Physical blends mean – we can separate and sort the separate parts based on physical properties • Boiling or melting points • Size • State of matter

  12. Filtration Uses a barrier to separate a solid from a liquid or gas in a mixture. Liquids and gases pass through and solid stays behind.

  13. Distillaton • Separate homogeneous mixtures made of liquids using the different boiling points of each part • Heat a mixture, the part with the lowest boiling point turns into a vapor, can be condensed and collected. Water purification

  14. Crystallization the formation of pure solid particles of a substance from a solution containing the dissolved substance

  15. Practice! Examples of mixtures will be placed on the board Your task: You have 2 minutes to: • Write down the example • Write down which separation technique you would use • Explain why (1-2 sentences) You can work in your group, but you must have your own answer sheet. At the end, will grade our answers as a class.

  16. Example #1 Before we can drink water from a river, we must remove all the dirt. What technique do we use? Why do we use that technique?

  17. Example #2 Salt is an important ingredient in many dishes and people have been getting salt from the ocean since ancient times. What separation technique do we use? Why do we use that technique?

  18. Example #3 Oil drillers take crude oil from the ground, but it must be processed in order for us to get gasoline, diesel fuel and materials for plastics. What separation technique do we use? Why do we use that technique?

  19. Example #4 I made some kool-aid, but I want the sugar back. What separation technique do I use? Why do I use that technique?

  20. Example #5 There is a lot of dust in the air and we need to get rid of it because Ms. Akagi is allergic to dust (but not really). What separation technique do we use? Why do we use that technique?

  21. Grading • Gather your group members papers together • Trade with another group • Each person will grade another person’s paper • 2 points per question (10 points total) • 1 point for the correct separation technique • 1 point for a correct explanation

  22. Example #1 Before we can drink water from a river, we must remove all the dirt. Filtration! Remove a solid from a liquid

  23. Example #2 Salt is an important ingredient in many dishes and people have been getting salt from the ocean since ancient times. Crystallization! Salt is dissolved in the water

  24. Example #3 Oil drillers take crude oil from the ground, but it must be processed in order for us to get gasoline, diesel fuel and materials for plastics. Distillation! Oil is a homogeneous mixture!

  25. Example #4 I made some kool-aid, but I want the sugar back. Crystallization! The kool-aid mix and sugar are dissolved in the water!

  26. Example #5 There is a lot of dust in the air and we need to get rid of it because Ms. Akagi is allergic to dust (but not really). Filtration! Remove a solid from a gas

  27. Grading: • 2 points per question • 1 point for correct technique • 1 point for correct explanation • Put the number of points out of ten at the top of the paper • Collect the papers in your groups • Have one person bring them up to the front

  28. Reminders • Homework is due on Thursday! • Lab fee $10 in Room 225 A • (free homework pass if paid by 10/22) • Test on 10/30/09 (next Friday) • You need a calculator EVERYDAY for the next two weeks!
