1. Separation of Mixtures

2. Evaluation/Assessment:
Objective:
Today I will be able to:
Explain how filtration, distillation, crystallization, and chromatography are used to separate solutions into their components
Analyze how detergents separate stains from clothing
Evaluation/Assessment:
Informal assessment: Listening to student interactions as they gather information about the separation of mixtures. Responding to student questions
Formal assessment: Analyzing student responses to the chart and exit ticket.
Common Core Connection
Build Strong Content Knowledge
Reason abstractly and quantitatively
Use appropriate tools strategically

8. Separation of Mixtures Chart
Work in groups of 4
Each person will be responsible for reading about one type of separation and filling in the chart
Once you have completed your section, share with your group members
If you have questions ask Mr. Klotz
15 minutes to complete this section

9. Separation of Mixtures Notes
Fill in any gaps on your charts as we review the following notes together

10. Filtration Used to collect solid particles on a filter
Works for heterogeneous mixtures containing a solid phase
Gravity allows for separation
Example Sand and Water

11. Distillation a pure liquid is recovered from a mixed solution
Two types
Simple Distillation – Salt Water
Fractional Distillation – Ethanol and Water
Effective because of different boiling points

12. Distillation Apparatus

13. Crystallization
A compound is heated and cooled down to produce crystals
Solubility
Salt Crystals

14. Chromatography – Think back to Biology

15. Chromatography Separate mixtures using absorbent paper Process:
Solution to be separated is placed on dry filter paper
A solvent is added and allows the solution to travel up the paper
Works due to capillary action

16. Read the article about stain removal and answer the questions
Whatever is not completed in class will become your homework

17. Exit Ticket
Brainstorm a list of real-life applications for each type of separation:
Filtration
Distillation
Crystallization Chromatography
