MATTER
- Definition: Any thing that's as mass and takes up space.
- This rock has matter.
- Feelings and thoughts are not made of matter.
PHYSICAL PROPERTIES
Definition: a characteristic of a substance that does not involve a chemical change.
This banana's color is yellow. Color is a physical property.
The fish in this market are smelly. Smell is a physical property.
This volleyball is round. Shape is a physical.
This tree's bark has a rough texture. Texture is physical property.
DENSITY
- The equation for density is mass divided by volume.
- If an object density is higher than 1 it will sink.
- If an object has a density less than 1 it will float.
This brick will sink because it has a density higher than 1.
SOLUBILITY
- Is the ability for a substance to desolve in a liquid.
This lemonade mix is soluble because it desolve a in the water.
PHYSICAL CHANGE
A change of matter from one form to another without a change of chemical property.
This ice changed from a solid to a liquid it went through a physical change.
Since this can is crushed it gas gone through a physical change.
This tinfoil changed from a flat sheet to a ball. It went through a physical change.
This Popsicle is changing from a solid to a liquid. It's going through a physical change.
CHEMICAL PROPERTIES
The ability to participate in a chemical change.
When iron is exposed to oxygen for a while it forms rust. This is called reactivity.

CHEMICAL CHANGES
A change that occurs when 1 or 2+ substances change into an entirely new substance.
