1. Water is made of H2O molecules
Water is made of H2O molecules. What do the molecules look like in each state of matter?

2. Making a foldable for STATES OF MATTER
Fold the paper hot dog style along the dashed line
Cut the top flaps along the solid lines to make three flaps

3. Flap 1- ?
Solid
These particles represent Atoms (if the solid is an element) or Molecules (if the solid is a compound)

4. Flap #1- Speed of particles: solid
How are the particles moving?
Tightly packed particles DO NOT move past each other. They vibrate in place.
Definite shape
Definite volume
The animation on this slide is meant to show students that the atoms in a SOLID object are moving, but cannot move past one another.

5. The only time particles of matter do NOT move, is when the temperature is absolute zero (-459 F)

6. Flap 2- ?
Liquid

7. Flap #2- Speed of particles: liquid
How are the particles moving in a liquid?
Tightly packed particles SLIDE past each other.
Definite volume
No definite shape
The animation on this slide is meant to show students that the atoms in a liquid are relatively close together, but slide past one another.

8. Flap 3 - ?
Gas

9. Flap #3- Speed of particles: gas
How are the particles moving in a gas?
Particles are not tightly packed together, and have so much energy they slip past each other quickly.
No definite shape
No definite volume
The animation on this slide is meant to show students that the atoms in a GAS move quickly and can spread a further distance than the atoms in solids and liquids.

10. Gases have NO DEFINITE SHAPE (They take the shape of the container)
Shape: Gas
Observe the following: Does the gas have the same shape in each container?
Gases have NO DEFINITE SHAPE (They take the shape of the container)

11. Volume: Gas
Observe the following: Does the gas fill the container?
What if I change the size of the container? Does the gas take up a different amount of space?
Gases have NO DEFINITE VOLUME (They can expand or compress to fill the container)

12. Think about passing gas, this smelly gas will expand to fill a room because gas has no definite volume!

13. 4th Phase of Matter: Plasma
Particles are moving so quickly it is hard to see what they are actually doing.
This animation is meant to show students that PLASMA is the phase of matter that is the fastest moving and it is impossible to see exactly how the atoms are moving.

Plasma on Earth: lightning, fire

18. Copper Phases - Solid

19. Copper Phases - Liquid

20. Copper Phases – Vapor (gas)

21. What do we call it when matter changes from one state to the next?
MELT
VAPORIZE/EVAPORATE
FREEZE
CONDENSE
SUBLIMATION

22. 1. A Review of the States of Matter
What phase of matter has the particles with the least amount of motion?
Solid

23. 2. A Review of the States of Matter
What temperature do particles show NO motion?
Absolute zero

24. 3. A Review of the States of Matter
What type of motion do particles have in a gas state?
Very far apart and they move very quickly.

25. 4. A Review of the States of Matter
What properties do liquids and solids have in common?
Definite volume

26. 5. A Review of the States of Matter
What properties do liquids and gases have in common?
Both take on the shape of the container they are in.

27. 6. A Review of the States of Matter
Infer: A scientist places 25 mL of a yellow substance into a 50 mL container. The substance quickly fills the entire container. Is it a solid, liquid, or gas and why?
Gas- takes the shape and volume of the container.

28. 7. A Review of the States of Matter
Why can I smell cookies baking in the kitchen when I am on the other side of the house?
Gases have no definite volume and will fill the container they are in.

29. 8. A Review of the States of Matter
What is the fourth state of matter?
Plasma

30. 9. A Review of the States of Matter
Which description best describes a solid?
It has a definite shape and volume
It has a definite shape but not definite volume
It adjusts to the shape of its container
It can flow A

31. 10. A Review of the States of Matter
In which state of matter do particles stay close together, yet are able to slip past one another?
liquid

32. So HOW does matter change its state?
