Solids
The animation starts with Neon in solid form.
Watch one particle for 15 seconds then……
 Draw a 9 particle sample structure in the appropriate top box below.
 Describe the motion of the particle you watched in the appropriate bottom box below.
Click on the menu box to the right to switch to the next substance. Do all four solids.
Neon solid
Argon solid
Oxygen solid
Water solid
DRAW:
WRITE:
What did all four solid particle models have in common?
Which model was different? Explain how it was different?
Liquids
Click on Liquid in the menu box. Water will be the first liquid shown.

 Draw a 9 particle sample structure in the appropriate top box below.
 Describe the motion of the particle you watched in the appropriate bottom box below.
Click on the menu box to the right to switch to the next substance. Do all four liquids.
Neon liquid
Argon liquid
Oxygen liquid
Water liquid

In general, how are the liquids different than the solids?
Review your drawings for solid water and liquid water. How do your drawings explain that the
density of solid water is less than the density of the liquid water?
Gases
Click on Gas in the menu box and note what gas you are observing.
Watch one particle for 15 seconds then……
 Draw a 9 particle sample structure in the appropriate top box below.
 Describe the motion of the particle you watched in the appropriate bottom box below.
Click on the menu box to the right to switch to the next substance. Do all four gases.
Neon gas
Argon gas
Oxygen gas
Water gas
DRAW:
WRITE:
What did all four gas models have in common?
How do gases differ from liquids?
How do gases differ from solids?
In Summary:
Given the terms fluid and rigid, use them to describe the phases of matter: solid, liquid and gas.
