This lesson is designed to: Review the definition of matter. Review the physical properties of matter

and how we use our senses to describe them.

Discuss how certain properties help us to sort matter into categories or states of matter.

Matter:

It’s what the world is made of.

What is matter?

• Everything in our universe is made of matter.

• All matter takes up space and has weight.

• There are 3 basic states of matter: Solid, liquid, Gas

What do you know about matter?

Liquids

GasesSolids

But what is the difference between a solid, a liquid, or a gas?

Solids

Solids hold their own shape.

Solids have weight.

Solids take up space.

Liquids Liquids take the

shape of their container.

Liquids have weight.

Liquids take up space.

Gases

Gases spread out to fill the entire space given.

Gases have weight.

Gases take up space.

STATES of matter?

What would it take for matter to move from one state to another?

Energy determines the state!

Solid

+ Energy =

Liquid

+ Energy =

Gas

All matter is made of molecules…

This is one water molecule (H2O)…

This is two H2Omolecules…

Molecules in Solids: Are packed tightly

together Molecules only have

space to vibrate. Have very little

energy

Molecules in Liquids: Are loosely

packed Molecules flow

freely Have medium

energy levels

Molecules in Gases: Move freely Molecules shoot

every direction Have LOTS of

energy

Add or subtract energy, and matter changes state!

What will happen when we add the energy from the sun?
