Solid

• Definite shape
• Definite volume

Evaporation
The warmth of the sun causes moisture to
evaporate from the earth and plants.
7
CONDENSATION

• Gases COOL off to form liquids
• clouds
• dew

8
DEPOSITION

• Gases COOL off too fast and form solids
• frost

9
Freeze
Cooling causes liquids to turn into solids.
10
Melting

• HEAT makes solids melt into
  liquids

11
Evaporate or Boil
Heat causes liquids to change into gases.
12
SUBLIMATION

• Solids HEAT up too fast and form gases
• Dry ice

13
This is.?
Evaporation (liquid changes to a gas)
14
This is an example of which change of state?
Condensation (gas changes to a liquid)
15
Why do we sweat? (Perspire)
Moisture EVAPORATING from our skin helps promote
cooling.
16
Is my glass leaking? Sweating?

• Condensation Change from a gas to a liquid
  because it is cooling off
• Where do we see this happening?
• Cars
• Grass
• Bus windows
• Seeing your breath
• ???

17
Observe
Keep your eyes open. Look for connections
Wonder
Why dat Do dat?
