1. The Stages of Matter
Solid
Liquid
Gas

2. Solids
Particles in a solid are tightly packed together in a regular pattern
The particles vibrate but do not move from place to place
A solid maintains its shape

3. Liquids
Particles of a liquid are close together but do not have a regular pattern
These particles vibrate, move about and slide past each other
A liquid takes the shape of
it’s container

4. Gas The particles of a gas are far apart with no pattern
These particles vibrate and move freely at high speeds
A gas takes the shape of its container and can change volume

5. States of Matter (write this down)
Solid - The molecules of a solid are tightly packed and do not move very far. A solid holds it’s shape.
Liquid - The molecules of a liquid are close together but move around a lot. A liquid takes the shape of its’ container.
Gas - The molecules of a gas are far apart and move quickly. A gas takes the shape of it’s container and expands or shrinks to fill its container.
