Chemistry- is the study of properties, and the behavior of matter.

This is the branch of science that deals with all the changes matter and properties undergo.

Matter-  All the actual stuff in the universe.

The only thing that isn't matter, is energy.

The basic forms of matter are liquid, gas and solids.

Molecule- is a substance that has two or more atoms with a definite agreement held together by chemical bonds.

Diatomic Molecule- Contains only two atoms.

Polyatomic Molecule- contains more than two atoms.

Mixture- A mixture consists of two or more different substances chemically combined.

the are two types of mixtures

heterogeneous- means different you can see all the different types of substances.

homogeneous- means the same, you can see all the parts of the mixture.

Solution- is a special type of mixture

It is a homogeneous mixture that contains a solute and a solvent.

solute- the solid part that gets dissolved

solvent- the liquid part that dose the dissolving

Matter- is all the substances that have mass and volume.
Chemical Change- is any change that results in a formation of a new chemical substance, chemical change happens on the molecular level.  It involves in the making or breaking of bonds. examples: iron rusting, mild souring, gasoline burning, or bread rising.
Physical Change- Physical change requires energy to be transferred. It requires rearrangement of molecules but doesn't affect their internal structure.  examples: boiling water, dissolving salt into water, or cutting up a potato.  

Here is a youtube video on the difference between chemical and physical change. It helps to further show the differences between the two.
