MATTER
Anything that has mass and takes up space (volume)
Sample concept map from Tuesday’s Activity
ATOM
Smallest part of a substance that is still that substance
ELEMENT
“Pure Substance” made of only one type of atom;
Molecule
Smallest part of a compound; can be broken down into elements by chemical means
MIXTURES
Combinations of substances that are not chemically combined; they can be separated by physical means
COMPOUND
Combination of two or more different elements; can be broken down into elements by chemical means
HOMOGENEOUS
Mixture whose parts are evenly distributed; you cannot see the different parts easily
HETEROGENEOUS
Mixture whose parts are unevenly distributed; you can see the different parts easily

2. To review:
A mixture is a combination of two or more substances that are not chemically combined
Two types:
Homogeneous: Uniform mixture
Heterogeneous: not the same throughout

3. Solution
Two or more substances mixed so it appears to be made of only one substance
Particles are evenly dispersed
Particles are small
Cannot settle out of the mixture.
There are two parts:
· SOLUTE: the substance that dissolves
· SOLVENT: the substance the SOLUTE dissolves in
Would this be Homogeneous or Heterogeneous?

4. Suspension
Particles are large and are dispersed throughout the mixture
Particles can block light
Particles can settle out if the mixture is left standing
Parts can be separated by filtering
Examples: Chocolate milk, orange juice, snow globes
Would this be Homogeneous
or Heterogeneous?

5. Colloid Particles are small to medium size They can block light.
They are dispersed throughout the mixture
Cannot settle out.
Particles cannot be filtered or picked out.
Examples: Whipped cream, Jell-o, deodorant, shaving cream, milk
Would this be Homogeneous or Heterogeneous?

Appears as one substance
Particles are small and do not settle

Particles are large and can settle out
