A lesson for students to learn about the interactions of matter

1. Matter:
IT’S WHAT THE WORLD IS MADE OF.

2. What is matter?
Matter is anything that has mass and takes up space.

3. What do you know about
matter?
Solids
Liquids
Gases
Plasma

4. Solids
Solids have definite shape and
definite volume.
Solids have mass.
Solids take up space.

5. Particles in Solids:
Are packed tightly together
Have very little energy
Vibrate in place

6. Liquids
Liquids take the shape of their
container and have definite
volume.
Liquids have mass.
Liquids take up space.

7. Particles in Liquids:
Are loosely packed
Have medium energy
levels
Particles flow around
each other

8. Gases
Gases spread out to fill
the entire space given
and do not have definite
volume.
Gases have mass.
Gases take up space.

9. Particles in Gases:
Move freely
Have LOTS of energy

10. Plasma
Lightning is a plasma.
Used in fluorescent light
bulbs and Neon lights.
Plasma is a lot like a gas, but
the particles are electrically
charged.

11. Particles in Plasma:
Are electrically charged
Have EXTREMELY high
energy levels

12. STATES of matter?
What would it take for matter to move from
one state to another?

13. Energy determines the
state!

14. Add or Subtract Energy. . .
When energy is added, particles move faster!
When energy is taken away, particles move slower!

15. What will happen? Why?

16. Solid + Energy = ?
When energy is added to
solids, they become
liquids!
Examples?

17. Liquid + Energy = ?
When energy is added to
liquids, they become
gases!
What examples can you
think of?

18. Changing States
There are several names for matter changing states:
◦State change
◦Phase change
◦Physical change

19. So, did we get something new?
Ice cream and melted ice cream?
Chocolate and melted chocolate?
Ice, water, and water vapor?
Steel and molten steel?

20. Think About These
Review Questions
1. What state of matter has definite volume and definite shape?
2. Describe the properties of liquids.
3. Describe the differences between gases and plasma.
4. What is needed for states of matter to change phase?
You will need to know this information for your assessment!
