-We reviewed the states of matter

-We drew the Solid, Liquid, Gas states of matter at the atomic level.
-We talked about how the atomic level predicts how the matter will act. (solid, little atomic movement, frozen in place)

-Classification of matter

-The difference between Mixture and Solution
-Difference between Pure substance and a Mixture
-Separation of mixtures
-We did a fun lab with filtration.

Research and answer the below questions:

1) Will passing salt water through a filter cause the salt to be filtered out?
2) If you pass a mixture of water and baking soda through a filter what will happen?
3) If you pass a mixture of corn starch and water through a filter what will happen?
4) if you pass a mixture of 'dirt' and water through a filter what will happen?
5) If you pass colored water through a filter what will happen?

define:

1) homogeneous
2) heterogeneous

Research-

1) some people think that there is plenty of fresh water on Earth because we can just filter the salt from salt water. Is that true?
