MATTER

Anything that has mass and takes up space

(volume)

HETEROGENEOUS

Mixture whose parts are unevenly distributed; you can see the different parts

easily

MIXTURES

Combinations of substances that are not chemically combined; they

can be separated by physical means

HOMOGENEOUS

Mixture whose parts are evenly distributed; you cannot see the different

parts easily

ELEMENT

“Pure Substance” made of only one type of atom;

COMPOUND

Combination of two or more different elements; can be broken down into

elements by chemical means

ATOM

Smallest part of a substance that is still that

substance

Molecule

Smallest part of a compound; can be broken

down into elements by chemical means

Sample concept map from Tuesday’s Activity

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

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?

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?

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?
