LTLT: I can identify properties of substances in a mixture to determine how the mixtures will be separated.

Learning Target:  I can review the types of separation methods used to separate a mixture 

Criteria for Success: I can create a scientific investigation I can describe all of the separation methods Agenda: Warm Up Review Quick Notes Thinking Lab Debrief Warm Up: What are the processes we have used to separate mixtures?  Review the LTLT, LT & CS Review the types of separation processes   QuickNotes:   Separation Methods- Quick Notes: 1.     Chromatography: ________________________________________________________         ______________________________________________________________________________________ 2.     Density: ____________________________________________________________________________                                                                                                                                                                                               _____________________________________________________________________________________ 3.     Distillation: _________________________________________________________________________        ___________________________________________________________________________________________ 4.     Condensation: _______________________________________________________________________       ______________________________________________________________________________________________ 5.     Magnetism: ____________________________________________________________________________________________      _________________________________________________________________________________________________ 6.     Filtration: ______________________________________________________________________       _______________________________________________________________________________________ 7.     Solubility: _______________________________________________________________________ ****Solvent: ______________________________________________________________________ *****Solute: _____________________________________________________________________________   Physical Properties Thinking Lab Q: If I gave you a mixture containing…. How would you separate it? HINT: This is your “cheat” sheet for your final lab… **Point out LT on POL…”Designing a scientific investigation” What are physical properties? **Use your notes    LTLT: I can identify properties of substances in a mixture to determine how the mixtures will be separated. Learning Target:  I can review the types of separation methods used to separate a mixture Separation Processes Thinking Lab *** You will need the information from this thinking lab for your FINAL PROJECT*** **** Do not lose this paper**** In this lab, you will be finding the physical properties of multiple substances. As you are exploring properties of each substance, keep this in the back of your mind: “what kind of information would help me separate this substance from others if it were in a mixture.” We have explored many ways to separate mixtures in this unit: 1.     Chromatography 2.     Density 3.     Distillation & Condensation 4.     Magnetism 5.     Filtration. 6.     Solubility Part 1: Physical Properties: Pretend you had a mixture composed of: Wood shavings, water, rubbing alcohol, sand, oil, salt, iron fillings , and colored dye For each piece of the mixture describe the physical properties. Use your notes.   *Wood Shavings: *Water:                                                                                                                                   *Rubbing Alcohol *Sand *Oil *Salt *Iron Filings *Colored Dye Part 2: Separation Processes: 1. For each of the above mixture ingredients, what separation method would you use to separate it from the larger mixture? 2. Describe HOW you would use that separation method. *Wood Shavings: *Water:                                                                                                                                   *Rubbing Alcohol *Sand *Oil *Salt (NaCl) *Iron Filings *Colored Dye Part 3: Separation Materials Think about what information, and materials would you need to use each method. List them here: *Chromatography: *Density: *Distillation & Condensation: *Magnetism *Filtration *Solubility:  Debrief: How do we separate mixtures?
