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

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)

1. Evaporation

4. Runoff or

Groundwater

3. Precipatation

2. Condensation
