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

liquid turning to solids due to removing heat

What happens to the gas

particles during the process of

freezing?

Lose heat

Less energy

Evaporate

liquids turning to gas due to heat being added

What happens to the liquid

particles during the process of

evapouration?
