1. Today is Wednesday, February 27, 2013
Homework: Read Chapter 11, Lesson 4 (for tomorrow)
Warm Up:
Look at the mixture inside the SMALL CUP at your table. Try to separate it out into its different components our your blue tray. Use the fork with the RED markings on it. Intentional messes, or not cleaning up accidents, will earn your whole table group one dart each.

2. Goal for Today
SWBAT Know differences in chemical and physical properties of substances are used to separate mixtures and identify compounds.

3. What are mixtures?
Mixture – different materials placed together but don’t bond to form compounds
Materials keep their own properties
Can separate materials according to their different properties
Iron filings and sand – use a magnet because iron filings are magnetic
Salt water – allow one to evaporate because they have different boiling points
Steel = iron and carbon
Brass = copper and zinc
Alloy – mixture of metals
Bronze – copper and tin

4. Pause for the Cause
What is a mixture of a solid and a solid you can think of?
A mixture of a solid and a liquid?
A mixture of a gas and a liquid?
Talk about it in table groups (1 minute)

5. One type of mixture is a solution
Special type of mixture in which substances spread out evenly and will not settle
Solute – dissolved substance
Solvent – substance in which the solute is being dissolved
Sugar water = solution
water = solvent, sugar = solute
Not all solutions are made by dissolving solids into a liquid
Two liquids, gas into a liquid
Other examples:
Gatorade
Kool-Aid
Coca-Cola (gas in a liquid – solution before it is opened and fizzes)
Tea
Coffee
Pure, filtered apple juice mixed with water (liquid in liquid)

6. Let’s make some drinkable mixtures!
Mix your drinks together
You may work with a partner or as table groups
The two forks WITHOUT RED are clean forks. Keep them clean and you can use them to stir your drinks
