TRANSCRIPT
How can we
measure and
describe the
properties of
matter?
What is matter?
• Matter is everything around
you, including you!
• Matter is what all things are
made of.
Matter has certain properties.
• Matter can have color.
• Matter can be different sizes.
• Matter can have different shapes.
• Matter can have texture.
• Matter can be rigid or bendable.
• Matter also takes up space
and has mass.
Properties are the characteristics of
matter, how something looks or feels.
We can group objects by their properties.
How can we group these objects?
1. Did you sort them by color?
One property is color.
Color
Red
Green
Yellow
Size
Large objects
Small objects
2. Did you sort them by size?
A second property is size.
Circles
SquaresTriangles
3. Did you sort them by shape?
A third property is shape.
Shape
Mass
Is the amount of matter in an object.
Tool for measuring mass.
Digital balance Two pan balance
Units for measuring mass.
Gram (g)
Kilogram (Kg)
Metric sy
stem
Volume
Amount of space an object takes.
Tool for measuring volume.(For liquids)
Graduated cylinder
Units for measuring volume.
Milliliter (ml)
Liter (L)
Metric sy
stem
Density
Amount of space an object takes.
Are the following matter?
1)Sunlight
2) An idea (you think of)
3) Water vapor
4) Balloon
5) Beaker
6) Oxygen
7) Aluminum foil
Water is matter.
Did you know it comes in all 3 forms?
A Solid A Liquid A Gas
ice water vaporwater
Matter has 3 forms.
1. Solid
2. Liquid
3. Gas
Solids
• A solid has its own shape.
• A solid does not change
unless you cut, bend, or break
it.
• Solids take up space and have
mass.
Liquids
• Liquids do not have
their own shape.
• Liquids take the
shape of their
container.
• Liquids take up space
and have mass.
Gases
• Gases have no definite
size or shape.
• Gases take the shape of
its container.
• A gas will fill all the space
inside a container.
• Gases take up space and
have mass.

Change of state
Occurs when a substance
changes from one state to
another.
HOW can we change states of matter?
Melt
when solids turn to liquids due to heat being added
What happens to the solid
particles during the process of
melting?
Gaining
heat
More energy
LiquidSolid
Melting point(The temperature at which a
substance melts)
Liquid Melting

Water Above
0°c
Freeze
liquid turning to solids due to removing heat
What happens to the gas
particles during the process of
freezing?
Lose heat
Less energy
Liquid Solid
Evaporate
liquids turning to gas due to heat being added
What happens to the liquid
particles during the process of
evapouration?
Gaining
heat
More
energy
Liquid Gas
Boiling point(The temperature at which a
substance boils)
Liquid Boiling

Water 100°c
Condensation
gas turning to liquids due to removing heat
What happens to the gas
particles during the process of
condensation?
Lose heat
Less energy
