Activities

**Ready for fruit loops???You need to complete all sheets

first, then see me to get your cereal.**

Record the title in your notebook.

Be sure to read ALL slides carefully and only take notes on

information that is in blue print.

States of Matter

States of MatterWe already know that matter is anything that has a MASS and

a VOLUME.

But if we were to sort ALL of the matter in the world into just

three categories, how could we do it???

States of Matter

The three states of matter are…

SOLIDLIQUIDGAS

States of MatterEach type of matter is made of particles/atoms

and they look different from each other.

Can you identify which of the following belongs to a

SOLID, LIQUID, AND GAS? Be sure to have a reason

WHY! Record your thoughts in your notebook!1. 2. 3.

ANSWERS!1. GAS 2. SOLID 3. LIQUID

SOLID MATTERSolid Matter:

atoms are packed close together (more dense)

has a definite volume and shape (don’t change shape or space it fills)

atoms vibrate a little, but not too much!

DRAW THIS EXAMPLE!

THINK ABOUT IT!!!

Consider a rock and how its size and shape stay the

same, regardless of where you put it.

You can break it, but it is still made of

solid rock particles.

SOLID MATTERWhat types of items do you

think are solid matter?Brainstorm a list in your

notebook!

SOLID MATTERAll of these solid examples below have a

definite shape and volume. Be sure to have at least three of these

examples in your notebook:

LIQUID MATTERLiquid Matter: has a definite volume (will always fill same amount of space)

can change shape by flowing (takes shape of any container)

atoms/molecules touch and can move around

DRAW THIS EXAMPLE!

THINK ABOUT IT!!!

Consider 8 ounces of milk. Its volume stays the same,

whether you put it in a saucer for the cat to drink or in a glass for yourself;

but its shape changes to match the shape of the

container.

LIQUID MATTERWhat types of items do you

think are liquid matter?Brainstorm a list in your

notebook!

LIQUID MATTERAll of these liquid examples below can change shape, but volume always stays

the same!Be sure to have at least three of these

examples in your notebook:

GAS MATTERGas Matter: no definite volume or shape (can change!)

can spread out forever OR take shape of container

have the most energy!particles do not touch and have low density (light)

DRAW THIS EXAMPLE!

THINK ABOUT IT!!!

Consider a sample of air.

It will fill an empty room, a balloon, a

tire, or a rubber raft. Its shape and

volume change to the shape and volume of the

container in which it is placed.

GAS MATTERWhat types of items do you

think are gas matter?Brainstorm a list in your

notebook!

GAS MATTERAll of these gas examples below can change its shape and volume!Be sure to have at least three of these examples in your notebook:

Helium gas in the

sun

Air in a bike tire

Change in Temperature

But what do you think happens to the atoms in matter when they

are heated or cooled??? Do any changes

happen?

Change in Temperature

*Temperature affects the atom’s energy levels!

Change in Temperature

Think about it…When you are hot, you normally don’t want anyone near you. You want to move far away from other

people so you don’t feel as hot.When you are cold, you want to get close and huddle with others

to stay warm!

Change in Temperature

Heated atoms gain energy and vibrate fast and expand (move

apart/more space)Cooled atoms,

lose energy and vibrate slower and contract

(shrink/get closer)

Change in Temperature

Think about a thermometer!

As it gets hotter, the liquid’s molecules inside the thermometer gain energy and expand.

Its volume increases (taking up more space).

Matter – Changes of State

Change in TemperatureThis happens to atoms in ALL states of

matter-solids, liquids, and gases.

What do you think would happen to any material if the temperature suddenly decreases from 70ºF to 30ºF? a. Expand because the molecules are gaining energy

and moving fasterb. Expand because the molecules are losing energy

and moving slowerc. Contract because the molecules are gaining

energy and moving fasterd. contract because the molecules are losing energy

and moving slower

Change in TemperatureWhat do you think would happen to any

material if the temperature suddenly decreases from 70ºF to 30ºF? a. Expand because the molecules are

gaining energy and moving fasterb. Expand because the molecules are

losing energy and moving slowerc. Contract because the molecules are

Finished???Be sure to have recorded all important notes that were in blue print. I will be checking notes and talking to you about what you have learned.

You may choose an option from Introduction B column.
