1. Anything that has mass and volume.
Matter
Anything that has mass and volume.

2. Mass
The amount of matter in a in an object or commonly referred to as weight.

3. Weight
The force of gravity between the earth or any other celestial body and an object being weighed.

4. Volume
The amount of space taken up by an object

5. Density
The amount of mass in a given amount of space.

6. How does the density of an object determine whether or not is floats?

7. Physical properties
Physical properties are things you can observe with your senses.
Physical properties can be observed without changing the identity of the substance.
Physical properties include color, texture, odor, density, the ability to conduct electricity, its state and its ability to react to a magnet.

8. A Substances State Solid Liquid Gas
All matter can be classified as Solid, liquid or gas.

9. Solid Tends to keep its shape Tends to keep it’s size
Resistant to a change in position.
Particle stay in a rigid arrangement.

10. Liquid Change shape easily
Assume the shape of their container but maintain the same volume.

11. Gas Change their size Change their shape
Change volume to fill the container.

12. State Compairison

13. Physical Change
A physical change is a change in size, shape, or state without forming a new substance.
Examples:

14. Changes in State

15. The temperature at which a substance changes from solid to liquid.
Melting Point:
The temperature at which a substance changes from solid to liquid.

16. Boiling Point
The temperature at which a substance turns from a liquid to a gas.

17. Like other properties melting and boiling points help to tell substances apart.

18. Mixtures
Any combination of two or more substances where substances keep their own properties.
You may or may not recognize this; for example perfumes are mixtures.

19. Suspensions A type of mixture. Parts separate when standing.
Products marked “shake well before using” are often suspensions.
Most solid particles settle to the bottom of a container.
You made need a filter or strainer to separate fine particles.

20. Emulsions
A suspension of two liquids that usually do not mix together.
Oil and water is an example of an emulsion. They will separate moments after you quit shaking them.

21. Colloids
A colloid contains undissolved particles or droplets that stay mixed in another substance.
Fog is a liquid-in-gas colloid.
Smoke is a solid-in-gas colloid

22. Solution A special kind of mixture
One substance is dissolved in another so that the properties are the same throughout.
All parts of a solution have the same properties such as color, odor and taste.
