This PowerPoint presentation introduces 3rd grade students to the three states of matter - solids, liquids, and gases. It defines each state, provides examples, and explains how water can switch between states. The learning objective is for students to correctly classify pictures as representing solids, liquids or gases.

2. Three States of Matter
 Content Area: Science
 Grade Level: 3rd
 Summary: The purpose of this instructional PowerPoint is
educate students on the three states of matter: solids,
liquids, and gases.
 Learning Objective: Given the PowerPoint on the different
states of matter, students will be able to classify the
pictures on slide 12 as solids, liquids, and gases, with 100%
accuracy.
 Content Standard: 0307.9.1 Use physical properties to
compare and contrast substances.
 Accomplishment: Identify the three states of matter

3. What is Matter?
The basic definition:
Matter is anything with mass
and takes up space

4. What are the States of
Matter?
 There are three states of matter: solids, liquids, and
gases.

5. What is a Solid?
A solid is the simplest and most tangible state of matter
A solid has these three main properties:
1. a definite shape.
2. a definite mass.
3. a definite volume.
A solid will always look the same and take up the same
amount of space.

6. Examples of solids

7. What is a Liquid?
A liquid is the most fluid and ever-changing state of matter
A liquid has these three main properties:
1. does not have a definite shape.
2. has a definite mass.
3. has a definite volume.
A liquid will always take up the same amount of space and
take the shape of its container.

8. Examples of Liquids

9. What is a Gas?
A gas is the most complex and difficult to understand state of
matter
A gas has these three main properties:
1. does not have a definite shape.
2. does not have a definite mass.
3. does not have a definite volume.
A gas does not always weigh the same or take up the same
amount of space. However, like a liquid, a gas will always
take the shape of its container, no matter the size or shape
of that container.

10. Examples of Gases

11. Switching Between States of
Matter
Water has the ability to easily switch between the
three states of matter.
ICE can be thawed to become WATER which can be
boiled to become STEAM which can condensate to
become WATER that you can freeze to make ICE!

12. Take out a sheet a paper and
identify the Solids, Liquids, and
Gases

13. Summary/Key Points
 Matter is anything is anything that has mass and takes up
space.
 The three states of matter are solids, liquids and gases.
 Solids have a definite shape, mass and volume.
 Liquids have a definite mass and volume, but not shape.
 Gases do not have a definite mass, volume, or shape.
