1. ESSENTIAL QUESTION:
Which state of matter (solid, liquid, gas, or plasma) do you believe is most important for survival? Explain your thinking.

2. The States of Matter What is matter? What are the states of matter?
How can you tell the different states of matter apart?
Can the matter change into different states?

3. Does Matter Really Matter?
BY LINDSAY PURNELL

4. Topics of Discussion: What is matter?
The three states of matter: Solids, liquids, and gases
Changing matter from one state to another
Matter in the real world

5. What is matter? Matter is EVERYTHING around you!
Matter is anything that has mass and takes up space.
Matter is anything made of atoms and molecules.

6. The Three States of Matter
SOLID
GAS
LIQUID

7. SOLIDS Retain their shape
Particles are tightly packed, usually in a regular pattern
Particles will vibrate but cannot move past each other

8. LIQUIDS Assume the shape of their containers
Particles are close together but do not form a pattern
Particles flow and can easily move past each other

9. GASES Assume the shape of their containers
Particles are well- separated with no regular pattern
Particles vibrate and move freely at high speeds

10. Classifying the States of Matter: What have you learned?
Get ready to test your knowledge on the different states of matter! Is it a solid, a liquid, or a gas? It’s up to you to figure it out!

11. Changes In Matter
Temperature and pressure can make matter change states. How does this happen???

12. Raising The Temperature
When heat is applied to matter, its state usually changes from solid  liquid  gas.
There are some exceptions in which the solid will go straight to a gas.

13. Lowering The Temperature
When matter is cooled, its state usually changes from gas  liquid  solid.
There are some exceptions in which the gas will go straight to a solid.

14. NAMES OF CHANGES Heating Cooling Solid  Liquid = MELTING
Liquid  Gas = BOILING
Solid  Gas = SUBLIMATION
Liquid  Solid = FREEZING
Gas  Liquid = CONDENSATION
Gas  Solid = DEPOSITION

15. How it “matters” in the real world…
Watch how these artists from Columbus, Ohio use the states of matter in their every day lives…

16. Lesson Summary: What is matter? What are the three states of matter?
How are these states different?
How does matter change from one state to another? Give examples.
How is matter important to us?
