Scientific Models: Scientists use models to understand the behavior of atoms and molecules and explain the properties of matter.

Everything that can be seen and touched is called matter.All matter on Earth exists in three forms: solid, liquid, or gas.

Solids, liquids, and gases are made of extremely tiny particles called atoms and molecules.

What is matter?

Matter is any substance that has mass and takes up space by having a volume.

States of matter

• On a piece of paper, draw particle diagrams for solids, liquids, and gases.
• Write down a sentence to describe each state.

Gas

Liquid

• Particles in a liquid are close together with no regular pattern.
• Particles in a liquid flow and can easily move or slide past one another.
• Liquids assume the shape of their containers.

• Particles in a gas are well separated with no regular pattern.
• Particles in a gas vibrate freely at high speeds.
• Gasses assume the shapes of their containers.

• Particles in a solid are tightly packed and usually in a regular pattern
• Particles in a solid will vibrate but cannot move past each other.
• Solids retain their shapes

• Add the names of the changes of state to your states of matter diagrams.

• What is it called when we change from one state to another?
