4. Classification of Matter
Go to page and read about colloids suspensions and solutions.
Define in your notes the italicized words.
What is a colloid?
What is a suspension?
How are they different from a solution?

6. Classification of Matter
List an example of each below:
Element  Zinc
Compound  Carbon Dioxide
Solution  Stained glass
Solid Mixture  Granite
Suspensions  Pulpy Orange Juice
Colloids  Milk, Jell-O, Hair Spray
In one minute I will unveil possible answers.
For homework come up with two other examples of each of the classifications of matter.
