*What are the states of matter?
Essential Question:
November 05, 2018
Matter
Matter is anything that has mass and takes up space.

*Matter is anything that has mass and takes up space.
Key Words: MATTER = ANYTHING THAT TAKES UP SPACE

How do you Define MatterMatter is Defined by it's properties. The properties of matter are, mass, volume, weight, and density. Mass is the amount of matter in an object. Volume is how much space an object takes up. Weight is the force of gravity on an object, and density is how heavy or light something is for its size.
*Mass: amount of matter in an object*Volume: How much space an object takes up*Weight: the force of gravity*Density: How heavy or light something is for its size

What are the States of MatterThere are three states of matter. Solids, Liquids, and Gases.

SOLIDSIn order for an object to be classified as a solid it must possess these properties. Solids must retain their shape, have the same volume regardless of the container, and can not be poured.
*Retain their shape*Constant volume*Can not be poured
Key Words: SOLID = FIRM & STABLE
NOTES:
November 05, 2018
LIQUIDSIn order for an object to be classified as a liquid it must possess these properties. Liquids take the shape of their container, do not have a definite volume, and can be poured.
*Take shape of container*No definite volume*Can be poured
Key Words: LIQUID = FLUID
NOTES:

GASESIn order for an object to be classified as a gas it must possess these properties. Gases fill the volume of their containers, can be poured, and do not have a fixed volume.
*Fill the volume of their container*No fixed volume*Can be poured

*What are physical changes?
Essential Question:
November 05, 2018
Physical ChangeA physical change is when matter changes in size, shape, or state without changing it's identity.
*Physical change is when matter changes size, shape, or state without changing it's identity
Key Words: PHYSICAL CHANGE = CHANGE IN SIZE, SHAPE, or STATE
NOTES:
November 05, 2018
Examples of a Physical ChangeExamples of a Physical Change:
-Melted-Frozen-Condensed-Evaporated-Crushed-Cut-When Salt or Sugar are dissolved in water
*Physical Changes can usually be reversed.

Can objects change their state?Yes, objects can change their state of matter by adding or removing heat.
*Can change their state by adding of removing heat*Add Heat:
*Cool:
SOLID LIQUID GAS
GAS LIQUID SOLID

So Lets check out some different experiments?
Quicksand....A solid or a liquid?
Instant Ice

What happens to the weight if an object changes.
If an object changes it state or breaks apart, the weight of the object does not change, which means the weight stays the same. So, let's look at an example.
Shrinking Styrofoam Cup
Even though the styrofoam cup shrunk in size it's weight did not change. The pressure compressed the tiny air pockets within the cup reducing it's size.
*If an object changes state:*Weight DOES NOT change
EXAMPLE:

What happens when objects are heated and cooled?
When the temperature of a material increases the particles move faster and expand or spread out. When the temperature of a material decreases the particles move slower and contract or shrink.
Examples:
*Increase in temp. particles expand or spread out*Decease in temp. particles contract or shrink*Water Expands when frozen
Key Words: EXPAND = SPREAD OUT CONTRACT = SHRINK

*What are chemical changes?
Essential Question:
November 05, 2018
What is a Chemical ChangeA chemical change is a change that results in the formation of a new substance. There are two parts to a chemical change. You have the reactant and you have the product. The reactant is the original substance. The product is the new substance. Some everyday examples are; Rust, Tarnish, Baking a Cake, and Engines.
*Chemical Change is a change that results in a new substance being formed*Reactant: Original substance*Product: New substance*Usually Cannot be Reversed*Examples:- Rust- Tarnish- Baking a cake- Engines (Cars and Rockets)Key Words: CHEMICAL CHANGE = CREATES SOMETHING NEW

How Do You Know A Chemical Change Has Occurred
A Chemical Change has occurred when you see one of these signs. There will be a color change, gas or bubbles will be produced, or you will see light or it will give off heat.
