    1. Composition of Matter

    2. All matter is made up of atoms. Elements- when all the atoms in the matter are the same. There are 118 elements. Ex: Carbon and Oxygen

    3. Compounds Compounds- matter that is made up of 2 or more combined elements. Compounds look different than the elements that make them up.

    4. Compound Ex: Ex: H & O = H2O C & O = CO2 C,H & O = C6H12O6

    5. Substance Substance- matter that is either an element or a compound.

    6. Mixture Mixture- material that is made up of 2 or more substances that can be separated physically.

    7. 2 Types of Mixtures Heterogeneous Homogeneous

    8. Heterogeneous Mixtures Heterogeneous Mixture- mixture that is unevenly mixed. You can see the stuff in the mixture.

    9. Heterogeneous Mixture Ex:

    10. Homogeneous Mixture Homogeneous Mixture- mixture that is evenly (uniformly) mixed. Homogeneous Mixtures are also called solutions.

    11. Homogeneous Mixture Ex:

    13. Colloid Colloid- a heterogeneous mixture that never settles. Ex: milk or fog

    14. Suspension Suspension- heterogeneous mixture that contains a liquid where visible particles settle.

    15. Suspension Examples

    16. Tyndall Effect Tyndall Effect- the scattering of light by particles in a mixture.

    17. Tyndall Effect Ex:
