1. Phases of matter
and how they change

2. Matter is made of particles
The three phases of matter are:
Solid
Liquid
Gas
Which they are depends on how tightly packed they are

3. Matter and the Particle model Matter has mass mass= # of particles Matter has volume Volume= the space between the particles
This is the title of your foldable
Cut it out and glue it to the top right of the construction paper

4. State or Phase solid low energy
Cut out this strip.
Fold it in half
Glue it to the right middle of construction paper
Open up the paper

5. On the left side
Draw this picture

6. On the right side Definite volume Properties Mass lots of particle
Volume particles are packed close together
Definite volume
Density most dense
Bonds particles are tightly bound together
Shape they have a definite shape
Speed particles only vibrate

7. State or Phase liquid medium energy
Cut out this strip.
Fold it in half
Glue it to the right middle of construction paper
Open up the paper

8. On the left side
Draw this picture

9. On the right side Definite volume Properties
Mass medium amount of particles
Volume particles have a little space between them
Definite volume
Density less dense than solids more dense than gas
Bonds particles are loosely bound together
Shape takes the shape of the container
Speed particles move a little bit

10. State or Phase gas high energy
Cut out this strip.
Fold it in half
Glue it to the top left of construction paper
Open up the paper

11. On the left side
Draw this picture

12. On the right side No Definite volume Properties
Mass very few particles
Volume particles lots of space between them
No Definite volume
Density least dense
Bonds no bonds between particles
Shape takes the shape of the container
Speed particles fly around fast

13. Phase changes Or how does water go from a solid to a liquid to a gas?
Add Heat
How does water go from a gas to a lquid to a solid?
Take away heat
These changes can happen with any kind of matter
Gold iron air helium alcohol Nail polish remover
Each od these changes has a special name.

14. Phase changes that require heat to be added
Cut out the add heat arrows
Colour them red
(one is upside down that’s good)
Fold them in half
Glue them down so that they link the phases
Solid  liquid
Open it up and on the inside write fusion or melting
Solid  gas
Open it up and on the inside write sublimation
Liquid gas
Open it up and on the inside write vaporization

15. Phase changes that require heat to be removed
Cut out the Take away heat arrows
Colour them blue
(one is upside down that’s good)
Fold them in half
Glue them down so that they link the phases
gas  liquid
Open it up and on the inside write condensation
Gas  Solid
Open it up and on the inside write deposition
Liquid solid
Open it up and on the inside write solidification or freezing

16. What phase change is this?
Jack frost painting pictures on your window in winter.
Dew on the grass is the morning.
Water on the outside of your cold glass of lemonade.
Melting ice cream.
Heating water in a teakettle until it boils.
“Fake smoke” in the movies.
Iodine crystals turning into purple gas.
Liquid silicon turning into glass.
Hardening liquid steel.
Eating a popsicle too slowly in summer.
