1. Classification of Matter
Pure substance
Mixtures
Compounds
Elements
Homogeneous
Heterogeneous
Organic
Inorganic

2. Classification of Matter
Matter is anything with mass and volume
Two general categories all matter can be divided into are
Pure substance: matter in which all the basic units are the same
Mixtures: substances that are put together but not chemically combined

3. Pure substances can be further subcategorized as
Compounds: Two or more elements that are chemically combined
Elements: Substance made up of only one type of atom

4. There are two types of compounds based on the source of the compound in nature, living or non-living substances
All living substances have carbon

5. Inorganic compounds: either contain no carbon or single carbon atoms
Organic compounds: most contain chains of carbon
All sources of energy in your diet contain organic compounds
What nutrients provide you with energy?
Inorganic compounds: either contain no carbon or single carbon atoms
Minerals and water are examples

6. Mixtures are classified as
Homogeneous: having a uniform distribution of particles throughout the sample
Solution: Homogenus mixture of one material dissolved into another
Solute- the material that is dissolved
Solvent- the material that does the dissolving
Heterogeneous: a non-uniform distribution of particles

7. Group Activity Using the Matter Classification concept map
List three examples of
Compounds,
Elements,
Heterogeneous Solutions,
Homogenous Solutions

8. Physical Changes
Physical Changes involve changing the shape, physical state, size, or temperature without changing the chemical identity
Phase change is a visible change in structure without changing the molecular structure

9. Chemical Changes
Occurs whenever new substances with different chemical and physical properties are formed
Evidence:
Color
Odor
Flavor
Release of gas
Transfer of energy (change in temperature)
