Solids, Liquids, and Gases

It surrounds us constantly, everywhere. Matter It surrounds us constantly, everywhere.

It makes up:

The books we read,

The food we eat,

The water we bathe in,

Even the air we breathe!

What does something have to be like to be called MATTER?

To be called MATTER, an object has to: Have mass Take up space (have volume) Exist as a solid, liquid, or gas

We can describe MATTER using something called PROPERTIES

Pick an object in this room. Describe some of its properties.

Now, pick an object that has different properties. Describe them.

solids, liquids, and gases, The properties of solids, liquids, and gases, Make them different from each other.

Think about the following questions. What would happen if you . . .

Tried to pick up a puddle of water? Why?

Blew through a straw into a glass of soda? Why?

Poured water from a container shaped like this: Into one shaped like this?

Tried to take a breath underwater?

Heated up a piece of plastic to a high temperature?

Tried to fit a basketball through a keyhole?

Put too much air into a balloon? Why?

Poured 12 ounces of orange juice into an 8 ounce glass? Why?

These objects behave the way they do because of their properties. Solids, liquids, and gases have different properties.

Write down some words that describe a SOLID.

Add these to your list: Definite shape Definite volume Particles are strongly attracted to each other Particles vibrate - but only slightly Particles are very close together

Write down some words that describe a LIQUID.

Add these to your list: Indefinite shape Definite volume Particles are less strongly attracted than in solids Particles move more freely than in solids

Write down some words that describe GASES.

Add these to your list: Indefinite shape Indefinite volume Particles have no attraction to each other Particles move freely There is LOTS of space between particles

With your group, pretend you are the particles that make up a SOLID. How might you look and act?

With your group, pretend you are the particles that make up a LIQUID. How might you look and act?

With your group, pretend you are the particles that make up a GAS. How might you look and act?

Can matter be changed from one phase to another?

How would you . . . . Change a solid to a liquid? Change a liquid to a gas?

Rank these in order from MOST to LEAST movement: solid, gas, liquid. Phases of matter differ because of the movement of the particles in them. Rank these in order from MOST to LEAST movement: solid, gas, liquid.

Adding heat energy makes particles move faster.

If you add heat to a solid ice cube, what do its particles do? What does it turn into? If you add heat to a solid ice cube, what do its particles do?

If you add heat to water, what do its particles do? What does it turn into? If you add heat to water, what do its particles do?

Matter is all around us. Whether it’s solid, liquid, or gas,

Thank goodness for matter!
