Introduction to Matter -What is matter? -Is anything not considered matter? -What are the three forms of matter?

Modeling the three phases Liquid Gas Solid

You will assigned a phase of matter: As a group you will have to -Model it -Explain the key details associated with that phase of matter You will have 10 minutes, then you will have to present it

Phases of Matter -What differentiates the different forms of matter? -What are the key characteristics? -How can we tell which is which?

Solid, Liquid, Gas -Shape -Compressibility -Volume

Physical Changes: -Reversible -Alter matter but composition stays the same Physical Properties: -Observable qualities

Chemical Property: -What occurs during a chemical reaction -Help ID unknown substances Chemical Change: -Cannot be undone -When reactants go through a reaction it is the end result

Physical or chemical property -Tastes sour -Boiling point -Reacts with water -length -Toxicity -P, P, C, P, C

Chemical or Physical Change -Baking a cake -Freezing ice cream -Burning Carbon -Formation of a snowflake -Spoiling milk -C, P, C, P, C

Substance: Can’t physically separate Mixture: Combination Of two substances Hetero: mixer and cookie dough, sugar cookie Homo:

Is it heterogeneous or homogeneous Oil and vinegar? Chocolate milk? Key aspect of heterogeneous vs homogeneous is in homogeneous Chocolate milk is homogeneous Oil and vinegar: heterogeneous

What is the difference between substance and a heterogeneous mixture?

What is the Law of Conservation of Matter?

What type of matter is this? -Identify the characteristics -Make observations -Develop a claim -Provide evidence to support your claim
