This document discusses the three forms of matter: solids, liquids, and gases. It explains their key properties - solids have a definite shape, liquids take the shape of their container, and gases fill their container and have no definite shape. Matter can also be described based on its properties, such as color, size, shape, texture, whether it is rigid or bendable. Properties are used to group and classify different objects. The document uses water as an example of how a substance can take on all three forms of matter as ice, liquid water, and water vapor.

1. Matter
by Denise Carroll

2. What is matter?
• Matter is everything around
you, including you!
• Matter is what all things are
made of.

3. Matter has 3 forms.
11.. SSoolliidd
22.. LLiiqquuiidd
33.. GGaass

4. 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.

5. Liquids
• Liquids do not have
their own shape.
• Liquids take the
shape of their
container.
• Liquids take up space
and have mass.

6. 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.

7. Water is matter.
Did you know it comes in all 3 forms?
AA SSoolliidd AA LLiiqquuiidd AA GGaass
ice water water vapor

8. Matter has certain properties.
Properties are the characteristics of
matter, how something looks or feels.
• 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.

9. We can group objects by their properties.
How can we group these objects?

10. 1. Did you sort them by color?
One property is color.
Color
Red
Green
Yellow

11. 2. Did you sort them by size?
A second property is size.
Size
Large objects
Small objects

12. 3. Did you sort them by shape?
A third property is shape.
Squares Triangles
Circles
Shape

13. We can group objects if they are
rigid or bendable.
• Bendable means that the matter can
bend, curve, or turn.
• Rigid means that the matter cannot bend,
it is stiff.
• Can you name something
that is rigid and something
that is bendable?

14. Which objects are rigid?
Which objects are bendable?

15. These objects
are rigid.
These objects
are bendable.
