Matter

SOLIDSSOLIDSWhat do you know about solids?

Can you list some solid objects in your classroom?

1. Solids

Word Definition Picture

- definite shape and volume. - Solids have their own shape.

- particles - close together and slow moving. - particles = low energy

LiquidsLiquidsCan you list some liquids in your classroom?

What do you know about liquids?

2. Liquid

Word Definition Picture

- definite volume but not a definite shape.

- Liquids take the shape of their container

- particles of liquids are farther apart and faster-moving than solids. - particles have more energy than solids

GASGASCan you list some gases in your classroom?

What do you know about gas?

3. Gas

Word Definition Picture

- no definite volume and no definite shape.

- spread out to fill and take the shape of their container

- particles of gases are farthest apart and move most rapidly.

- gas particles = most energy!

Yes

No – takes shape of container

Medium – faster moving molecules

Liquid water, soda, Kool-Aid, gator-aid
