Substances•Elements- simplest kind of matter
• Cannot be broken down into simpler• All one kind of atom.
•Compounds are substances that can be broken down by chemical methods
• When they are broken down, the pieces have completely different properties than the compound.• Made of molecules- two or more atoms

Mixtures•Made up of two substances.•Heterogeneous- mixture is not the same from place to place.
• Chocolate chip cookie, gravel, soil.•Homogeneous- same composition throughout.
• Kool-aid, air.•Every part keeps its properties.

Solutions•Homogeneous mixture•Can occur between any state of matter.
• Solid in liquid- Kool-aid• Liquid in liquid- antifreeze• Gas in gas- air• Solid in solid - brass• Liquid in gas- water vapor
•Like all mixtures, they keep the properties of the components.•Can be separated by physical means
