Students will be able to… List the states of matter, their properties
and relate them to real world situations and to Earth science.
Describe the phases of matter and define each.
Observe the forms of matter
Warm-up Notes/discussion Video clips – gases - plasma Crossword review – Chap. 4: What is Matter
Physical Properties of Matter Chap. 4 sec. 2 continue
Physical Properties of Matter
Four States or Phases of Matter
Solid – has a definite shape and a definite volume
Example –ice, book, desk
In a solid, atoms are in a fixed position relative to each other.
Liquids – has a definite volume but no definite shape.
Takes the shape of its container
Example: water, mercury
In a liquid, the atoms are free to change position with each other.
Gas – has no definite volume and no definite shape
Example: Steam (water vapor)
In a gas, the atoms are free to move independently of each other.

Plasma - is the most common kind of matter in the universe.
Plasma is matter in the state of ions and
electrons (charged particles)
Example: stars, lightning, auroras

Add or take away – Energy
Energy – the ability to do work
Examples: heat, light, nuclear
Matter plus energy
Ice + heat = water solid melting liquid
Water + heat = water vapor liquid evaporation gas
Evaporation – is the process of changing from a liquid to a gas
Matter minus energy
Water vapor - heat = water gas condesation liquid
Condensation – is the process of changing from gas to liquid
Water – Heat = Ice liquid freezing solid
The exchange of water amoung Earth’s hydrosphere (water), geosphere (land), and atmosphere (air). (4 steps)
